How to hydroisolate and tile a bathroom or a wet room with tiles?

The most important thing about this case-study:

  • The hydroisolation eliminates the chance of leakage in the lower rooms and defends the concrete construction from moisture.
  • The applying of the tiles in the bathroom starts from the walls and finishes with the tiles on the floor.
  • Every one of the used cement pastes, glues and grouts have to be waterproof or hydrophobic, the silicones and the sealants with increased protection of mold.
  • Extra impregnate the fugues.
  • Read carefuly the instruction for applying of every product. Their correct following is very important for the durability of their coverage.
  • You must apply the tile adhesive not only on the foundation, but also on the back of the tile, because that way there are no cavities left under them, which could fill with water.
  • Apply the hydroisolation not only on the floor of the bathroom, but also on the walls on the height of the wetting.
