Water-based wall primer & undercoat for uniform topcoats.
The product, up close.
The problem it solves.
A topcoat is only as good as the undercoat beneath it. Uneven, absorbent surfaces give patchy, weak finishes.
A water-based undercoat with strong adhesion and alkali resistance.
Contractors preparing walls before emulsion.
Interior and exterior plaster and concrete.
What it is.
A water-based wall primer and undercoat that improves substrate consolidation and topcoat performance, providing excellent adhesion, good alkali resistance and a uniform finish. Easy to apply and fast drying.
