Repair joints in the bathroom

Joints between tiles and on the edges of sanitary facilities initially serve a functional, inconspicuous purpose. But if they are dirty and damaged, they clearly devalue the entire room. You can upgrade your bathroom accordingly by touching up the joints.

Depending on whether you want to repair plaster or silicone joints, various measures are recommended.

Plaster joints

In cemented joint plaster between wall and floor tiles, dirt and lime can accumulate in the grainy surface structure. As long as no mold has spread and you are only bothered by the yellowish or grayish discoloration that remains after thorough cleaning, you can simply freshen it up optically with a grout pen. Grout paint also brings very beneficial results and is also mold-resistant. This permanently prevents the formation of mold. However, it can only be used with glazed joints.

If the cleaning joints are not only discolored, but molded or placed in places, they should rely completely completely. Scratch the surface on the damaged areas with the help of a joint reel or an electric ridge. Take care not to damage the tiled edges and, for example, take a square wood as protection limit to help. Then fill in the recessed places with special, water-repellent moisture room mortar and elapse instructions.

Silicone joints

Silicone joints, which as seals between the bath or shower tray and tiled wall or. Shower cabin wall are attached, can accommodate much dirt, soap residues and mold spores in your rubbery material. If they were discolored black, mold has already spread and is usually no longer completely removing. If there are still fragile areas due to incorrect maintenance, you should completely replace the joint.

To do this, after cleaning the area, scrape out the old joint with a craft knife (€ 15.00 on Amazon *). When doing this, close the drain so that the old silicone does not get into the pipeline. Stubborn residues can be removed with silicone remover. Press the new silicone joint into the crack with a spray gun. Because the silicone shrinks as it dries, the new joint should be about 1-2 mm thicker than the old one. To smooth it out with a putty knife, wet the silicone with a little soapy water.
