Step by step solution
The substrate must be sound, clean, strong enough to bare weight, free from dust, dirt, grease, oil or any contaminating materials that can cause
For waterproofing over gypsum, apply 2 coats of acrylic waterproofing membrane
weberdry gum with the use of weber band embedded in the 1st coat (in all corners and sensitive points).
Apply webercol paste, a dispersing tile adhesive, uniformly on the substrate and use the notched spatula to achieve the required thickness.
Apply the tiles and press them strongly on the substrate in order to spread the product evenly on the walls. webercol paste can be used over gypsum substrate without any primer.
It is recommended to have a minimum joint width of 2 mm around the tiles. Grouting should be done at least 24 hours after fixing tiles, using weberepox easy, weberjoint perfect or weberjoint deco.
Apply with a rubber trowel in a diagonal direction to completely fill the joint. Remove excess material from the surface with a damp sponge. When the grout is dry, clean it with a dry cloth.
Gypsum plaster loses most of its cohesive strength when wet, so it needs to be protected in areas wet areas. Therefore, a protecting layer such as weberdry gum is required when applying in wet areas.
