GSA Acrylic Gap Filler White 450g

The fine gaps along skirtings, architraves and cornices are what separate a tidy paint job from a rushed one. Gap filler closes them up so the finish reads clean.

This is a paintable, water-based acrylic filler that stays flexible, so it moves with the timber instead of cracking out when the seasons change. It guns into the gap, tools off with a wet finger, and paints over once it's set.
