Bare Wood

1. Lightly sand wood in the direction of the wood grain
2. Any old, decayed, loose wood must be removed before treating the affected area with Ronseal Wet Rot Wood Hardener prior to filling
3. Any existing woodworm can be eradicated with Ronseal Woodworm Killer
4. Fill any gaps in the wood with Ronseal High Performance Wood Filler or Ronseal Multi Purpose Wood Filler
5. Clean and degrease the wood by wiping over with a lint-free cloth dampened with white spirit prior to coating

Previously Painted Wood

1. If paint is in good condition, a light sanding is all that is needed
2. If paint is flaking, peeling or cracked, it must be taken back to bare wood by stripping or sanding
3. If the wood shows signs of rot or decay, follow the process above for 'Bare Wood'
4. Wipe down with white spirit, being sure to remove any excess sanding dust before applying Ronseal One Coat Wood Primer

Always do a small test area before beginning any project to assess adhesion and overall performance. Follow the manufacturer's instructions on the tin at all times. Stir thoroughly before use.

1. Apply Ronseal Wood Primer and Undercoat with a good quality synthetic brush or microfibre roller
