Thistle GypPrime makes your job easier, giving you extra working time by reducing the suction base to prevent rapid drying.
It's easy to apply by roller, brush or spray, and is coloured yellow so you can see where you've treated. When the primer is diluted, it can cover up to 600 square metres. However, you can also apply it neat to correct extremely dry surfaces.
