Dukkaboard AQUA77 Primer is an eco-friendly, water-based surface isolation product for dry, absorbent mineral, cement, gypsum or anhydrite-based substrates. It is part of the AQUA77 Waterproofing System, and is used to seal substrates before applying AQUA77 Neo-Flex and AQUA77 Tanking Fleece.
It is also available as part of the AQUA77 Waterproofing Kit.
Dukkaboard AQUA77 Primer is single-component, with very low volatile organic compound emissions. Safeguards the health of both operators and the environment.
Dukkaboard AQUA77 Primer develops an isolating, cohesive film which neutralizes the expansive chemical reaction of gypsum or anhydrite-based substrates in contact with mineral mortars and adhesives, and reduces and regulates the absorption of highly porous substrates.
Dukkaboard AQUA77 Primer is a professional, concentrated water-base isolation product for gypsum and anhydrite substrates before ceramic tiles are laid using cement based adhesives or before paint is applied to walls.
