Half-timbered house, plasterboard walls, underfloor heating in the screed. The joint between the floor and the wall is constantly getting cracks. Is there a way to deal with this phenomenon?
Remove the cement mortar and seal the joint with silicone in the color of the tiles. In general, there are decorative corners for such joints in almost any color. However, they are installed as part of the process of laying tiles.
There are special additives (liquid) for elasticity of grouting cement, added in the process of mixing grout. And silicone must be chosen by color-not always possible to find a color to match the tile.
