Contractors grade PVA for general purpose bonding, sealing and priming of construction materials. Effectively primes and seals porous surfaces, such as interior walls. Ideal for use in combination with concrete, mortar and plaster, to improve adhesion to the substrate and seal dust/flaking surfaces.

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.

Bostik Renderer’s Grit has been specially developed for the rendering professional. Previously called Renderer’s Stabilising Primer, it primes and stabilises most exterior surfaces to give extra grip prior to the application of new render.
It can be applied straight from the bucket onto previously rendered walls, as well as other porous and non-porous surfaces including brick, blocks, concrete, render and plaster. When rendering externally it removes the need for initial scratch coats, only receiving render is required. The grit suspended in the product provides an excellent mechanical key.
Renderer’s Grit can also be used on internal shiny surfaces such as sound, well adhered ceramic tiles before plastering. Bostik Renderer’s Grit is coloured grey to show uniform coverage and only one coat is required using a short pile roller or soft brush to provide an even key for render. It gives a more uniform surface that dries evenly, providing excellent adhesion and a faster, easier finish. It reduces suction on porous surfaces, allowing a consistent rendering working time and reducing the risk of cracking.
