Product details
Product information
Product information
Bostik Plasterer's Grit is specially designed for the plastering professional. The pregrit product primes and stabilises most interior surfaces, providing an excellent key for skim coats. Unlike other plasterer's primers, this product doesn't contain sand, meaning it doesn't require mixing and can be applied straight from the bucket with a brush or roller. The particles in Plasterer's Grit don't flick off the brush or roller like sand can, so there's no mess during the application and no risk of sand being dragged through the plaster as with other products. Sand-based plasterer's grit products can also absorb moisture from the plaster, which causes it to dry too quickly and crack. With Bostik Plasterer's Grit plaster bonding agent, the risk of cracking is significantly reduced. The plasterer's primer can be applied to porous and non-porous surfaces including brick, block, concrete, plaster or plasterboard. The high-performing plaster stabilising solution can even be used on problem surfaces, such as well-adhered emulsion paint and wallpaper adhesive residues. Once applied, it can be left to dry completely before the first coat of plaster is applied, meaning you don't have to wait around for it to go tacky and are free to complete the job at a time that suits you. The distinctive colour of the green grit for plastering makes for a controlled application and ensures even coverage.

Fab product
Brilliant product, prepped the walls that were very bad lathe plaster ready for my plasterer to come and skim the room. Made the walls very secure where they were basically like dust before. And the plaster was able to grip nicely to the walls. I used brushes and rollers to get it on the walls as the roller alone didn't get the job done, probably because walls were so bad. It's like painting with gritty melted ice cream. So it takes a bit of time getting used to working with the texture.

Excellent did the job it was meant to do. Nice plaster finish now. Essence of a good job is preparation.

Does what it says on the tin
I used this product on extremely dry porous walls and it kept shrinkage to a minimum, definitely worth for a better finish over blue grit
Wyller - 2 / 5 - 25/02/2026
Good enough for the job
Nope. It does do the job but its more messy and complicated than traditional ways
