Preparation
Ensure that wooden surfaces to be treated are clean, dry and free from dirt, dust and any other surface contaminants. Make sure the room temperature is above 10°C. Put down dust sheets to cover any areas that do not need painting.
- Lightly sand wood using 120 grit sandpaper in the direction of the wood grain to give it an even finish
- Vacuum and wipe wood over with white spirit, being sure to remove any sanding dust, prior to painting
- Any instances of wet rot can be treated with Ronseal Wet Rot Wood Hardener, and any existing woodworm can be eradicated with Ronseal Woodworm Killer
- Fill any holes or cracks with Ronseal High Performance Wood Filler or Ronseal Multi Purpose Wood Filler
Application
Always do a small test area before beginning any project to assess performance. Follow the manufacturer's instructions on the tin at all times. Stir the contents of the tin thoroughly prior to use.
- Apply Knot Block Wood Primer using a good quality synthetic brush in the direction of the wood grain
- Allow 4 hours to dry, then apply a second coat
Finishing
Once fully dry, Ronseal Knot Block Wood Primer & Undercoat can be over-coated with Ronseal Stays White Ultra Tough Paint, Ronseal Stays White One Coat Non Drip Paint or Ronseal Diamond Hard Floor Paint.
