How to cover stains and hairline cracks on ceilings
1. Ensure the surface and hole are dry and free from loose material.
2. Using a filling knife, apply the Polycell Deep Gap Polyfilla directly into the hole and smooth off with a wet knife.
3. For holes over 20mm deep, build up in layers, leaving the filler to dry in between.
4. Once the surface is dry, sand the area to a smooth finish and it’s ready to be painted over.
5. When you’ve finished using Polycell Deep Gap Polyfilla, pop the lid back on and wash your tools in warm water.
