Prime Porous Substrates. Get the Bond Right First Time.

Arbokol AG2 Porous Primer is a specialist primer designed to improve adhesion of sealants and adhesives to porous substrates such as concrete, masonry, brick, stone, and timber. Applying a primer to porous surfaces before sealing ensures the sealant bonds to the substrate rather than being absorbed into it — giving you a stronger, longer-lasting joint that won't fail prematurely.

Supplied in a 500ml tin.
