Meet Bostik GRIP A936 XPRESS — the quick-drying, water-based wonder primer that makes even the slipperiest floors behave. Perfect for smooth, shiny, or non-absorbent surfaces like tiles, metal, terrazzo, or concrete that’s as dense as your mate Dave.
It’s got tiny bits of quartz in it, which basically act like built-in sandpaper — giving your next layer something to grab onto. And no, you don’t need to go mad with grinders or sanders beforehand.
It dries in about 2 hours, doesn’t stink, and won’t gas you out since it’s solvent-free.
Roll it on nice and thin (around 80–120 g/m²) with a short roller, let it fully dry, and then get cracking with your levelling compound. Works a treat with Bostik’s Screedmaster range and underfloor heating too.
Whether you’re fixing up an old floor or laying a new one, this primer helps everything stick properly so it doesn’t peel up later. Think of it as double-sided tape for grown-ups.
