Definitions
- the present invention relates to a method for grouting joints having coverings such as slab coverings and the like.
- the present invention is therefore based on the object of providing an improved method of the type mentioned at the outset which avoids the disadvantages of known methods.
- the process should have coverings with joints that are optically and flawlessly available quickly and efficiently.
- this object is achieved in a method of the type mentioned in that the visible surfaces of the covering are coated at least in the area of the joints with a sealant which can be redissolved in an aqueous medium, then the joints are filled with the desired jointing agent and then the sealant is sealed. Solvent is dissolved with aqueous medium and removed.
- the surfaces of the covering to be kept clear of the grouting agent are therefore first provided with a protective layer, so that the grouting agent cannot adhere directly to the surface of the covering. Applied next to the joints
- Grouting agents can be removed by dissolving or Layer can be removed easily and effortlessly after the grouting has set.
- the grouting process can accordingly be carried out efficiently, since dirt on the visible surface of the covering can be removed easily.
- coverings made of porous materials are protected from dirt that can no longer be removed.
- the sealing layer advantageously prevents the jointing agent from acting directly on the visible surface of the covering.
- discoloration of the natural stones can be prevented, which can be caused by the action of the grouting agent and can no longer be eliminated.
- a film-forming sealing agent is applied to the visible surface of the covering.
- the surface to be protected is sealed flat and tight.
- the film can be very thin, preferably it can have a thickness in the range of about 0.5 to 1 mm or less.
- the sealant is water soluble.
- the sealant could also be soluble in an alkaline medium. However, it is preferably water-soluble. This has advantages with regard to simple and harmless processing when grouting the covering, in particular with grouting agents that are not based on water.
- Grouting agent used a mortar based on synthetic resin, especially based on epoxy resin.
- an epoxy resin mixture in particular in connection with quartz sand, a high-strength and tight joint can be achieved with simple processability.
- Such a mortar does not dissolve the sealing layer.
- the sealant is advantageously biodegradable. This significantly simplifies processing. The sealant can simply be dissolved in water and washed away. Any sealant that penetrates the floor does not permanently pollute it.
- a sealant based on carbohydrate, in particular gum arabic or starch dextrin, is particularly advantageous. Sealants based on carbohydrates are easy to process, harmless and effectively seal the surfaces of the flooring that are to be kept free of grout.
- the sealant can also contain powdered fillers. This is particularly preferred when coarse-porous covering plates are to be temporarily sealed.
- the sealing agent is expediently applied in such a way that the side surfaces of the covering parts facing the joints remain essentially free of sealing agent.
- the sealing agent is only applied to the visible surfaces of the covering that are to be kept free of the grouting agent.
- the grout can adhere to the remaining free joint sides of the covering parts and achieve a firm bond with the covering parts.
- the joint mortar provides a good seal of the joints between the covering parts.
- the sealant is preferably applied mechanically in aqueous solution, in particular rolled on or spread on. As a result, the sealant can be applied quickly and locally to the visible surfaces of the covering.
- the sealant preferably has a viscosity in the range from 25 to 75 cP, in particular approximately 35 to 70 cP, at approximately 20 ° C.
- the sealing agent can preferably have thixotropic agents.
- the sealant is advantageously slightly liquid during brushing, but has a significantly greater toughness when at rest, so that no drops or tears can form on the coated surface. This simplifies the processing of the sealing means, in particular in the case of inclined or vertically laid plate coverings, such as wall coverings.
- the invention is suitable for all types of coverings to be grouted, in particular slabs and paving, regardless of whether outdoors or in buildings and regardless of wall or floor.
- Coarse-porous coverings as are known, for example, using porous artificial stone slabs according to DE-U-91 16 773, can also be temporarily sealed according to the invention. The pore filling from the sealant can be easily washed out again.
- FIG. 1 shows a cross section through a covering, which shows two covering parts with an intermediate joint, the covering being shown in an intermediate stage of the jointing after the grout has been filled in and before the sealing layer has been removed
- Fig. 2 shows a cross section through the covering corresponding to Fig. 1, wherein the covering is shown fully grouted.
- the covering 1 shown in FIGS. 1 and 2 is only shown in sections and can be a floor covering, such as on terraces or building icons or a paved street covering, but also a wall covering.
- the covering is in several parts and has plates 2, in particular natural stone plates, between which joints 3 lie.
- the plates 2 of the covering 1 are attached with an underside to the floor or the wall. As FIGS. 1 and 2 show, the underside of the plates 2 is embedded in a support 4, for example made of sand or gravel or mortar or the like.
- the sealing agent is first rolled or spread over the entire surface of the free upper side of the plates 2, so that it forms a sealing layer 5 on the upper side (FIG. 1).
- the sealing layer 5 extends on the upper side of the plates 2 around the joints 3 and completely covers them, but the outer side surfaces 6 of the plates 2 which face the joints 3 and delimit them remain free of sealing agent.
- the sealing layer 5 therefore does not extend on the side surfaces 6 of the plates 2.
- the joints 3 are filled with joint mortar 7.
- this can be done by sweeping in the grout.
- 2 grout is also applied unintentionally to the top 8 of the plates.
- this does not come into direct contact with the plates 2 itself, but can only sit on the sealing layer 5 and form det dirt there 9.
- the top 8 of the plates 2 is washed off with water, for example sprayed with water and / or brushed off. Since the sealing agent is water-soluble, the sealing layer 5 is dissolved and detached or washed from the top 8 of the plates 2. At the same time, the contaminants 9 are also washed away by the grout 7 from the visible top 8 of the plates 2. After the sealing layer 5 and the impurities 9 have been washed off, the covering 1 is properly grouted (FIG. 2).
