Product details

Product information

  • Water-based
  • Apply using a Brush or roller
  • Instructions for Use - Make sure the surface is clean, dry and free from loose particles or mould. Remove any wallpaper or loose paint. Fill holes or cracks with an appropriate Polycell product and sand down well. This is not a cure for damp, which should always be treated at source before applying, also not suitable for use against rising damp. Should not be used at ground level, where efflorescent salts are present or where condensation is a problem. Use a brush or roller, allow new plaster to dry for at least 1 to 2 weeks before using this product. Stir well, do not thin. Apply the product generously to damp but not saturated surfaces working well over the affected area while avoiding runs. Avoid splashing on polystyrene tiles or any plastic materials. Allow to dry fully before over coating overnight. Treated surfaces are now ready to decorate, drying of wall coverings especially viny coverings may be slower.
