Sealants

Sealants here cover protective and remedial treatments applied to existing substrates: concrete, tiles, walls, roofs, facades and terraces.

Protect, remediate, clean

• Protective varnishes for concrete and tiles, some of which are presented as suitable for foot traffic.
• Treatments for damp walls, by injection or as a colorless application against saltpeter.
• Fungicidal treatments against green deposits, algae and lichens on roofs, facades and terraces.

Before choosing, the buyer checks the type of substrate to be treated, the cause of the problem (rising damp, biological soiling, surface wear), the method of application and the product's technical data sheet. The buyer also checks compatibility with the existing materials, the level of traffic expected on the treated area and the precautions for use on the site and its surroundings.

For a renovation or building maintenance project, compare offers from several suppliers and request quotes through the quote selection. More general solutions are gathered in Structural work : Waterproofing.
