Roll on primer for cement sheet, flush jointed block work, AAC and racked brick. Including, well adhered “gloss free” painted surfaces.
Armatex Firewall Aggra-Prime is an aggregate filled water reducible primer supplied ready for use straight from the drum except for the addition of fresh clean cement which speeds up cure times during cold weather applications and further enhances adhesion to mineral substrates.
The product is applied by roller or brush and is suitable for application to most correctly prepared mineral based construction surfaces such as cement sheet, flush jointed block work, AAC and racked brick. Including, well adhered “gloss free” painted surfaces.
The product is principally used on cement sheet to seal the board, reduce suction and provide a non-skid surface. The non-skid surface aids in the application of the render coat that is required across the entire project to feather pre-filled panel jointing and nailing points before the application of an acrylic texture and topcoat.
