    The present invention relates to a use of a grinding tool. The present invention further relates to a sealing set for producing a seal of a transition area between adjacent components against water. The present invention also relates to a method for sealing a transition area between adjoining components against water.
    [0002] Sealing tapes are used, for example, in the sanitary sector to seal a joint between a built-in object and an adjacent part of the building in a watertight manner. According to DIN 52460, a joint is the intended or tolerance-related space between components. In order to allow movement compensation between the adjoining components, the sealing tapes are designed to be flexible and, in particular, to be permanently elastic. The sealing tapes can also be used to seal a transition area, for example in a building corner, between two adjacent walls or between a wall and an adjacent floor or between two adjacent floor sections. The sealing tapes usually have their own adhesive surfaces so that they can be glued to the adjacent components. In principle, however, the sealing tapes can be glued to the components in addition or as an alternative to their own adhesive surfaces by means of sealing slurry or liquid sealing paints, with tile adhesive or the like.
    Tiles or damp-proof panels are laid at least in sections over the installed sealing tapes, in particular after completion of the sealing arrangement. After the laying work, joints between the adjoining components, for example between an installation item such as a shower or bathtub and an adjoining tile or damp-proof panel, are closed by means of elastic joint seals, for example with silicone as a sealant. Such elastic joint seals are considered maintenance joints and require regular maintenance and care. Accordingly, the sealant used to produce the joint seal must be checked at regular intervals and replaced if necessary. When removing the aged sealant, pointed, sharp cutting tools, for example knives, cutters or carpet knives, are usually used. It can happen that when the sealant is removed, the cutting tool is set too low and the sealing arrangement behind it, for example the sealing tape or a sealing layer made of a liquid or sheet-like sealant (sealing slurry, sealing paint, sealing membrane or the like) is damaged or even cut.
    From DE 10 2010 050 752 A1 a sealing tape with an integrated flexible cut protection is known. The cut protection can, for example, be a flexible metal foil that is intended to prevent the sealing tape from being cut through completely. It is also known that the flexible cut protection can be inserted from the outside in a pocket formed on the sealing tape. By integrating the cut protection in the sealing tape or by inserting the cut protection in a pocket formed on the sealing tape, however, it cannot be prevented that sealing coatings applied to the sealing tape or in part the sealing tape itself are damaged. In addition, the sealing tape is expensive to manufacture.
    The present invention is therefore based on the object of providing a cut protection that protects the sealing arrangement better and is cheaper and easier to assemble. Furthermore, the present invention is based on the object of providing a sealing set that better protects the sealing band or the sealing arrangement and is more cost-effective and easier to assemble. Another object of the present invention is to provide a method in which the sealing arrangement is better and more easily protected.
    The object is achieved in a use of a grinding tool with a grinding layer as a cut protection for a sealing arrangement of the type mentioned for sealing a transition area between adjacent components against water.
    The advantage is that the cutting tool used when removing the joint seal, for example a knife, a cutter or carpet knife, becomes blunted when passing the grinding tool on the grinding layer and thus loses its cutting effect. Because the grinding tool is a tool with which a workpiece can be machined in a manner known per se. Grinding is a cutting manufacturing process that is standardized in DIN 8589. Grinding is a machining process with undefined cutting edges. If the fitter in particular presses a blade of the cutting tool against the cutting tool and pulls it past the grinding layer, material is thus removed by cutting from the cutting tool, in particular from its blade. As a result of the blunting of the cutting tool, an increased expenditure of force would now have to be applied in order to be able to cut into the sealing arrangement located behind the grinding tool. Since audible scratching noises occur when the cutting tool is pulled past the grinding tool, the craftsman is also made aware that the cutting tool is being set too low. Damage to the sealing arrangement arranged behind the grinding tool is reliably prevented in this way.
    [0008] The grinding tool is expediently already mounted when the sealing arrangement is being produced. The grinding tool can be handheld. In the installed state, in which the grinding tool is arranged on the sealing arrangement, the grinding layer of the grinding tool is preferably directed outwards, that is to say arranged on the side of the grinding tool facing the joint. The grinding tool is preferably arranged on the outside of the sealing arrangement. Depending on the configuration of the sealing arrangement, the grinding tool can also be arranged in the transition area directly on the sealing tape or directly on a sealing layer of a liquid or sheet-like sealant. In principle, however, it is also possible for the grinding tool to be embedded in the sealing arrangement, for example by coating it with a liquid or sheet-like sealant after assembly.
    For fastening to the sealing arrangement, the grinding tool can have at least one adhesive surface. The at least one adhesive surface is arranged in particular on a side of the grinding tool facing away from the grinding layer. In the simplest case, this can be the adhesive surface of a double-sided adhesive tape, which in turn is glued to the grinding tool.
    The grinding tool can have an elongated shape. This means that the grinding tool can be many times longer than it is wider. The grinding tool is expediently at least 10 times as long as it is wide, in particular at least 15 times as long as it is wide. This allows the grinding tool to be arranged in a simple manner in the transition area parallel to the joint seal. The grinding tool expediently has a width that is at least essentially constant over its length. At least essentially means that the width can vary by up to +/- 10 percent. The width of the grinding tool can be between 10 millimeters and 50 millimeters, preferably between 15 millimeters and 30 millimeters. Particularly good results were achieved in terms of handling and cut protection with a grinding tool width of 20 millimeters. In this way, the grinding tool covers the usual joint widths, which are usually between 1 millimeter and 6 millimeters, sufficiently to ensure sufficient protection for the sealing arrangement when the elastic joint seal is renewed.
    In a preferred manner, the grinding tool has a maximum thickness of 3 millimeters. The minimum thickness of the grinding tool can be 0.5 millimeters. With such a thin design of the grinding tool, the grinding tool can be arranged in a simple manner in the transition area without endangering the seal between the adjoining components against water. The maximum thickness of the grinding tool is preferably less than 2.0 millimeters, in particular less than 1.5 millimeters, in particular a maximum of 1.0 millimeter. The grinding tool preferably has the grinding layer only on one of the two main sides which extend parallel to the longitudinal axis of the elongated grinding tool, in particular on the main side of the grinding tool on the joint side or on the room side. The abrasive layer can be a continuously closed abrasive layer or have no lattice structure. This reliably prevents the cutting tool from cutting into the sealing arrangement. The rear main side of the grinding tool, with which the grinding tool can be attached to the sealing arrangement, can be free of abrasive, whereby a particularly thin grinding tool is provided.
    Furthermore, the grinding tool can have a length of at least 0.5 meters, in particular of at least 1 meter and / or a maximum of 20 meters. As a result, the grinding tool is particularly suitable for use in the sanitary area, for example to provide cut protection for the sealing arrangement when creating a seal for a transition area between a floor-level shower tray and the adjoining fixed wall and floor components. In a very preferred manner, the grinding tool can be cut, for example using pliers, a knife or conventional household scissors. The grinding tool can thus be shortened or cut in length in order to be able to adapt it to the respective installation situation at the installation site.
    [0013] The grinding tool can be designed as a particularly flexible grinding belt. The grinding belt can preferably have a length of more than 3 meters and less than 20 meters. The grinding belt can be provided as a roll and can in particular have a length of 10 meters. The thickness of the grinding belt is preferably less than 2 millimeters, in particular less than 1.5 millimeters, in particular less than 1.0 millimeter. Thicker sanding belts are too brittle and are only suitable to a limited extent in order to be able to adapt them to the installation situations in the sanitary area. Alternatively, the grinding tool can be rigid. For example, it can be a flat bar so that the grinding tool can be made available as bar goods that can be butted against one another in corner areas. Manageable lengths are between 0.5 meters and 4 meters.
    [0014] The grinding tool is preferably designed to be flexible or pliable. According to EN ISO 527-1, the modulus of elasticity of the grinding tool can be less than 10,000 Newtons per square millimeter. The flexible grinding tool can be easily adapted to structural conditions and, for example, can also be guided around corners or radii. The grinding tool can thus be guided in one piece over a corner area of a built-in object, in particular a shower or bathtub, in order to be able to equip the transition area in the corners with the cut protection.
    According to one aspect of the present invention, the grinding tool is designed as a grinding belt, in particular for metalworking. Such an abrasive belt is flexible and can also be referred to as an "abrasive on a pad". A commercially available abrasive belt can be used to equip the sealing arrangement with the cut protection.
    Furthermore, the grinding tool, in particular the grinding belt, can have an abrasive carrier with a front surface and a rear surface facing away from the front surface for fastening the grinding tool to the sealing arrangement. The abrasive carrier forms the base of the grinding tool. The at least one adhesive surface, by means of which the grinding tool can be fastened to the sealing arrangement, is preferably arranged on the rear surface of the abrasive carrier. It is advantageous that due to the at least one adhesive surface attached to the rear surface of the flexible abrasive belt, in particular in the form of the double-sided adhesive tape, the abrasive belt forms fewer cracks when it is bent or kinked.
    The grinding layer is preferably attached to the front surface of the grinding tool, or applied to the front surface. Furthermore, the abrasive layer can be applied flatly on the front surface of the abrasive medium carrier and can in particular cover the front surface over the entire area or completely. The grinding tool preferably has the grinding layer only on the front surface. Thus, the back surface of the grinding tool can be free of abrasives, so that the grinding tool can be made particularly thin.
    [0018] In particular, the abrasive layer has at least one binder and abrasive grains. The at least one binder can be applied to the abrasive carrier and the abrasive grains sprinkled on the at least one binder in a manner known per se. The abrasive grains can have been applied using an electrostatic scattering process in order to align the abrasive grains in such a way that they are distributed evenly with defined spaces or without gaps and with defined positioning of the grain tips on the abrasive carrier. The scattering process can also be a mechanical scattering process in which the abrasive grains are applied randomly. The abrasive layer can thus have a rough contact surface which is formed by the projecting portions of the abrasive grains, which can come into grinding engagement with the cutting tool in an abrasive manner. As is well known, grinding is a machining process with undefined cutting edges. The individual abrasive grains have the smallest individual cutting edges that are distributed irregularly. These arise during the manufacture of the cutting tool through the dressing and profiling (conditioning) of the grinding layer through grain splinters. In addition to the abrasive grains and the bond composed of at least one binder, the abrasive layer also has pores. The pores, also called pore space or chip space, lie between the abrasive grains and are not filled with the binder. The pores serve to receive or transport away the chips and are accordingly open to the outside of the grinding layer. When the cutting tool moves past the grinding layer, the individual cutting edges of the abrasive grains that come into contact with the cutting tool remove material chips from the cutting tool, which twist into the pores and can basically fall out of the pores again. In this way, a particularly high amount of material is removed from the cutting tool when it is pulled past the grinding layer. In order to ensure that the mostly metallic blade of the cutting tool is quickly blunted, the abrasive grains can be made of silicon carbide, corundum (aluminum oxide), zirconium corundum, ceramic corundum or diamond, for example. Mixtures of different abrasive grains can also be provided in the abrasive layer.
    [0019] Furthermore, the abrasive grains can only be arranged in a single layer in the abrasive layer. This provides a thin grinding tool. In particular, the abrasive grains are distributed homogeneously in the abrasive layer. It is advantageous if the abrasive grains cover at least 60 percent of the front surface of the abrasive backing. The closer the abrasive grains are applied to the abrasive carrier, the higher the abrasion performance and the associated cut resistance of the grinding tool. The abrasive grains preferably cover at least 70 percent, in particular from 80 percent to 100 percent of the front surface. In a preferred manner, the abrasive carrier is almost completely, preferably completely covered with the abrasive grains. This so-called dense scattering, in which at least 80 percent of the front surface is covered with abrasive grains, enables high material removal in metalworking. Since the cutting tools that are usually used to remove the joint sealant mostly have a metallic blade, the grinding tool with its dense distribution is particularly suitable as a cut protection. It is advantageous if the abrasive layer has as high a proportion as possible of the abrasive grains, since these can come into abrasive engagement with the cutting tool through their protruding sections. Preferably, more than half of the volume of the abrasive layer is filled by the abrasive grains. In relation to the abrasive layer, in the ratio of the volume proportions of the abrasive grains and the at least one binder, the volume proportion of the abrasive grains can thus be greater than 50 percent by volume, in particular more than 60 percent by volume, in particular more than 70 percent by volume. The at least one binder preferably only serves to hold the abrasive grains in the abrasive layer.
    A particularly effective cut protection against the mostly metallic blades of the cutting tool is given with the abrasive grains, which have an average grain size (d50) between 1815 micrometers and 39 micrometers, preferably between 642 micrometers and 100 micrometers. The information relates to the entirety of all abrasive grains present in the abrasive layer. The mean grain size (d50) can be determined, for example, by sieving. It has been shown that smaller abrasive grains do not offer sufficient protection against cuts and that too coarse abrasive grains remove too little material from the usually metallic blades of the cutting tools. With reference to the FEPA standard, the abrasive grains can thus have grain sizes between P12 to P360, preferably P30 to P150, in particular between P36 and P120. The grinding tool preferably has abrasive grains with grain sizes P36, P40, P50, P60, P80, P100 or P120.
    In order to improve the resistance of the grinding tool to water, the at least one binding agent can have a synthetic resin. The at least one binder can have a resin, in particular a synthetic resin, and a hardener. In addition to the abrasive grains, the structure of the abrasive layer can include further components, for example a base binder, a top binder and, if necessary, an additional application. The base binder, the top binder and / or the application can comprise the same binder or binders that differ from one another. The bond is preferably an all-synthetic resin bond. The abrasive layer can be fastened or glued to the abrasive carrier by means of the at least one binding agent. This allows the abrasive layer to bond closely to the abrasive backing.
    The abrasive carrier can be made of a tear-resistant material that can be cut. Tear-resistant is intended to mean in particular that the abrasive backing cannot be torn with both hands. This provides a sufficiently stable grinding tool for installation in sanitary areas, which can also be cut to length in a simple manner, for example using household scissors, thanks to the design that can be cut, in order to be able to adapt the grinding tool to the installation conditions at the installation site. In order to be able to be cut, the abrasive carrier can have a maximum thickness of 2 millimeters, in particular a maximum of 1 millimeter. The density of the abrasive backing can be less than 2 grams per cubic meter, in particular less than 1.5 grams per cubic meter. Furthermore, the abrasive backing can have a basis weight of less than 2000 grams per square meter and preferably more than 100 grams per square meter. In particular, the weight per unit area of the abrasive backing is between 300 grams per square meter and 1000 grams per square meter, in particular between 500 grams per square meter and 700 grams per square meter.
    In order to improve the resistance of the grinding tool to water, the abrasive carrier can have at least one fabric tape, in particular a polyester fabric or a cotton-polyester blend. In principle, however, other materials, in particular paper, plastic films, vulcanized fiber, foam or combinations thereof, can also be used.
    According to a further aspect of the present invention, the grinding tool can have an indicator which, when irradiated with at least one defined wavelength, emits light in the visible spectrum, or between 780 nanometers and 380 nanometers. Since the cut protection cannot be seen behind the joint sealant to be serviced when installed, the installer cannot determine before removing the joint seal whether a cut protection has been used when producing the sealing arrangement. The grinding tool acting as a cut protection can be more easily detected by the indicator. For this purpose, the fitter only removes a small section of the joint seal that is sufficiently large to illuminate or illuminate the section of the sealing arrangement located behind it with a light source. If visible light is emitted during irradiation with the at least one defined wavelength, the fitter knows that a cut protection in the form of the grinding tool has been arranged on the sealing arrangement. Then the installer can remove the remaining joint seal faster and more carefree. Furthermore, the indicator can also be used during a construction inspection to check whether the described grinding tool was used as a cut protection during the production of the seal.
    [0025] The indicator can in particular have solid and / or liquid particles that are added to the grinding layer. In order to achieve the most homogeneous possible distribution of the indicator in the grinding layer when using solid particles, the indicator can be added, for example, in powder form or dust form. In particular, the indicator can be admixed with the at least one binder. The indicator can also be an application of paint on the grinding layer. It is also possible for the indicator to be applied to the abrasive carrier when the at least one binding agent and / or the abrasive grains are / is transparent. Furthermore, the indicator can be or comprise a fluorescent additive. The indicator can preferably contain or be a fluorescent agent which can be activated by UV light. Such a UV indicator can fluoresce light in the visible range when irradiated with black light or with a wavelength of less than 380 nanometers, for example between 240 nanometers and 300 nanometers. In particular, a UV lamp can thus be used to activate the indicator or to make it fluoresce.
    A solution to the above-mentioned object is further a sealing set of the type mentioned for producing a seal of a transition area between adjacent components against water, comprising a particularly flexible sealing tape, a grinding tool and means for at least indirectly attaching the grinding tool to the sealing tape. The grinding tool can be designed according to one of the above-mentioned embodiments. With the sealing set according to the invention, the same advantages result as with the grinding tool according to the invention, or its use as a cut protection, so that reference is made to the above description in this regard.
    [0027] The sealing tape and / or the grinding tool are preferably rolled goods. The means for at least indirectly attaching the grinding tool to the sealing tape can comprise at least one adhesive surface which is attached to the rear surface of the grinding tool.
    One solution to the above-mentioned object is also a method for sealing a transition area between adjacent components against water of the type mentioned at the beginning, which method has the following steps: providing a grinding tool which can be designed according to one of the above-mentioned embodiments; Gluing a sealing tape to a first component of the adjacent components and to a second component of the adjacent components; Fastening the grinding tool at least indirectly to the sealing tape, the grinding tool at least partially covering the transition area between the first component and the second component. The grinding tool can be designed according to one of the above-mentioned embodiments. With the method according to the invention, the same advantages result as with the grinding tool according to the invention, or its use as a cut protection, and the sealing set according to the invention, so that reference is made to the above description in this regard.
    A preferred embodiment of the present invention is illustrated in the drawings and described below. Herein shows:<tb> <SEP> FIG. 1 shows a sectional view of a grinding tool according to an embodiment of the present invention, which according to the invention can be used as a cut protection; and<tb> <SEP> FIG. 2 shows a sectional view of a sealing arrangement according to an embodiment of the present invention with the grinding tool shown in FIG.
    In the figure 1, a grinding tool 1 is shown with a grinding layer 2 according to an embodiment of the present invention. The grinding tool 1 can be used as a cut protection for a sealing arrangement for sealing a transition area between adjoining components 3, 4 against water. The components 3, 4 are shown in connection with the sealing arrangement shown in FIG.
    The grinding tool 1 has a shape extending along a longitudinal axis X, that is to say elongated, with a constant width that extends transversely to the longitudinal axis X. The grinding tool 1 is, here, designed as a flexible grinding belt, which can be provided as rolled goods. Such a grinding tool 1 can also be referred to as a grinding belt or “abrasive on a base”. In the sanitary sector, it has been shown to be particularly advantageous in terms of manageability and cut protection if the grinding belt 1 has a length of 10 meters and a width of 20 millimeters. The thickness D1 of the grinding belt 1 is a maximum of 2 millimeters, preferably a maximum of 1 millimeter. The grinding tool 1 is particularly suitable for machining metal.
    Specifically, the grinding tool 1 has an abrasive medium carrier 5 with a front surface 6 and a rear surface 7 facing away from the front surface 6. A double-sided adhesive strip 8 is applied over the entire surface of the rear surface 7 of the abrasive carrier 5 and is used to fasten the abrasive belt 1 to the sealing arrangement. On the front surface 6 of the abrasive carrier 5, the abrasive layer 2 is applied, which, here, covers the entire front surface 6 of the abrasive carrier 5 flat.
    The abrasive layer 2 has at least one binder 9 and abrasive grains 10 fixed in the binder 9, of which only one is provided with the reference numeral 10 in FIG. 1 for the sake of clarity. The abrasive grains 10 are arranged exclusively in a single layer and distributed homogeneously in the abrasive layer 2. The abrasive carrier 5 is almost completely covered with the abrasive grains 10. Almost completely means that the abrasive grains 10 are densely scattered (so-called “dense scattering”) and, here, cover more than 90 percent of the front surface 6 of the abrasive material carrier 5. The abrasive grains 10 are, for example, made of silicon carbide, corundum, zirconium corundum or ceramic corundum. The mean grain size (d50) of the abrasive grains 10 is preferably between 538 micrometers and 125 micrometers.
    In relation to the abrasive layer 2, in the ratio of the volume proportions of the abrasive grains 10 and the at least one binder 9, the volume proportion of the abrasive grains 10 can be greater than 50 percent by volume. The at least one binding agent 9 can be a reactive adhesive, in particular comprising synthetic resin and hardener, in which the abrasive grains 10 are firmly held. The bond of the abrasive layer 2 is preferably a fully synthetic resin bond. The abrasive layer 2 is held intimately on the abrasive carrier 5 via the at least one binding agent 9. Furthermore, an indicator can be applied to the grinding layer 2 which, when irradiated with at least one defined wavelength, for example with 254 nanometers, emits light in the visible range. The indicator can additionally or alternatively be contained in the grinding layer 2.
    The abrasive carrier 5 can be made of a tear-resistant material that can be cut. The weight per unit area of the abrasive backing 5 is less than 2000 g and preferably more than 300 grams, preferably between approximately 520 grams and 680 grams, in particular approximately 600 grams. The material can be, for example, a polyester fabric material or a cotton-polyester blend fabric material. The thickness D5 of the abrasive backing 5, i.e. its extension transversely to the longitudinal axis X and transversely to the transverse extension (width), is constant over the longitudinal axis X and is a maximum of 1 millimeter, preferably about 0.7 millimeter.
    In FIG. 2, the sealing arrangement is shown with a sealing set according to the invention in an installation situation in a sanitary area. The sealing set has a flexible sealing tape 11 for producing a seal of the transition area between the two adjoining components 3, 4 against water. The first component 3 is, here, a built-in object, for example in the form of a shower tray, which is sealed off from a stationary second component 4, such as a wall or a floor, here a wall of a building by means of the sealing arrangement. The sealing set also has the grinding tool 10 described in connection with FIG. 1, which serves as a cut protection for the sealing arrangement behind it.
    The sealing tape 11 has a narrow and elongated shape. A width of the sealing tape 11 that is in particular constant over the length of the sealing tape 11 can be between 60 millimeters and 120 millimeters. The sealing tape 11 is designed to be flexible and permanently elastic and can be provided as rolled goods.
    Furthermore, the waterproof sealing tape 11 has a first longitudinal side 12 and a second longitudinal side 13 which faces away from the first longitudinal side 12. In the installed state, the first longitudinal side 11 faces the shower tray 3 and the second longitudinal side 13 faces the wall 4. On the first longitudinal side 12 of the sealing tape 11, there is a first adhesive section 14 for sticking the sealing tape to the tub rim 15 of the tub 3 that faces the wall 4. Outside the first adhesive section 14, the sealing tape 11 has on the first longitudinal side 12 a section 16 with a knitted fabric or a flexible nonwoven fabric to improve the adhesion of further components of the sealing arrangement, in particular a sealing slurry or another sealing coating on the sealing tape 11.
    On the second longitudinal side 13 of the sealing tape 11, two further adhesive sections 17, 18 are arranged. With a view to FIG. 2, the lower adhesive section 17, which can be a butyl strip, is used to glue a sound insulation strip 19. The upper adhesive section 18 can also be a butyl strip in order to provide a permanently watertight connection to the wall 4. The two adhesive sections 17, 18 form a continuous adhesive surface, whereby it is basically also possible for the two adhesive sections 17, 18 to be spaced from one another in the transverse direction of the sealing tape 11. In a central band section 20 of the sealing band 11, which can extend over part of the section 16 with the knitted fabric, the sealing band 11 bridges a gap 21 between the wall 4 and the tub 3, which forms the transition area, in the installation situation shown here .
    To assemble the sealing arrangement, the sealing tape 11 is first connected to the tub rim 15 by the first adhesive section 14. Furthermore, the optional soundproofing strip 19 is connected to the lower adhesive section 17 of the sealing tape 11. Before the shower tray 3 is installed, the wall 4 can be provided with a first sealing layer 22, for example by applying a liquid sealant or by applying a sheet-like sealant. The shower tray 3 is moved with the preassembled sealing tape 11 to the wall 4 until, here, the optional sound insulation strip 19 rests on the wall 4. The upper adhesive section 18 of the sealing tape 11 is then connected to the wall 4. In the installed state, the middle band section 20 lies at least substantially above an imaginary extension of an upper edge 23 of the tub rim 15. Subsequently, a further sealing layer 24 can be applied to the wall 4, with the section 16 of the sealing tape 11 extending above the tub rim 15 at least partially can also be covered with the further sealing layer 24. The sealing arrangement can thus comprise the first sealing layer 22, the sealing tape 11 and the further sealing layer 24, it being understood that the sealing arrangement can also comprise only one of the sealing layers 22, 24 or more than two sealing layers. A sealing arrangement without the sealing tape 11 is also conceivable, for example in a vertically upright corner area between two walls that are adjacent to one another.
    The grinding tool 1 shown in FIG. 1 is attached to the sealing arrangement. For this purpose, the grinding tool 1 is glued to the sealing tape 11 by means of the adhesive strip 8 arranged on the rear surface 7 of the abrasive carrier 5 or, if the further sealing layer 24 has also been applied to the middle section 20 of the sealing tape 11, to the dried further sealing layer 24. The grinding tool 1 covers at least the middle band section 20 of the sealing band 11 and protrudes at its lower end slightly below the imaginary extension of the upper edge 23 of the tub rim 15 in order to provide adequate protection against cuts even with a cutting tool attached at an angle from above.
    Subsequently, to complete the composite seal, the sealing arrangement equipped with the grinding tool 1 as a cut protection can be covered in subsequent work steps, here, with tiles 25, which hold onto the sealing arrangement with tile adhesive 26. The grinding tool 1 can be covered with the tile adhesive 26 or left out of this. A joint 27 is now formed between the lowermost tile 25 and the tub rim 15, which is finally closed in a manner known per se with the elastic joint seal (not shown). Silicone, for example, can be used as a sealant for the joint seal. It can be seen that the grinding tool 1 is arranged between the joint 27 and the sealing arrangement and thus protects the sealing arrangement behind the grinding tool 1 from unintentional damage when the joint seal is renewed.
    With the recurring replacement of the joint seal, a cutting tool used to remove the silicone joint, for example a knife, cutter or carpet knife, can no longer cut into the sealing arrangement 11, 22, 24 located behind the grinding tool 1 with normal effort. The cutting tool pulled past the grinding tool 1 when removing the silicone joint becomes blunt on the grinding layer 2 and thus loses its cutting effect. The resulting scratching noises also warn the fitter that the cutting tool is being set too low.
