Bostik A790 Acrylic Crackle White – 300 ml Cartridge

Bostik A790 Riss Acryl – textured acrylic sealant for cracks and joints

Bostik A790 Riss Acryl is a ready-to-use acrylic sealant for sealing and repairing cracks and joints in mineral substrates. Its granular texture allows the surface to blend in particularly well with adjacent plaster and masonry surfaces.

This makes A790 particularly suitable for repair, renovation, and patching work on walls and facades. Once fully dried, the white sealant can be painted over.

Technical data

Application

The surfaces to be treated must be clean and load-bearing. Remove loose particles, dust, and other contaminants that may reduce adhesion before application.

Open the cartridge, cut the nozzle to the desired application width, and use a cartridge gun to apply A790 evenly into the crack or joint. Then smooth the surface to match the adjacent texture.

The material must be fully dried before painting over. When used outdoors, protect the fresh material from rain and heavy moisture during drying.
