Tips & Advice

  • 1. Preparing the Surfaces
    Make sure surface is clean, dry and free from loose particles and mould. Remove any wallpaper or loose paint. Fill holes or cracks with an appropriate Polycell product and sand down well. The product is not a cure for damp, which should always be treated at source before applying and is not suitable for use against rising damp. The product should not be used at ground level, where efflorescent salts are present, or where condensation is a problem.
  • 2. Cleaning
    Remove paint form the brush or roller with a cloth then wash with water.
  • 3. Storing
    Store paint in dry conditions and protect from extreme temperatures.
