Previously Painted Wood
If paint is in good condition, a light sanding is all that is needed
If paint is flaking, peeling or cracked, it must be taken back to bare wood by stripping or sanding
Be careful preparing surfaces that were painted prior to 1960 as they may contain harmful lead
If the wood shows signs of rot or decay, follow the process above for ‘Bare Wood’
Wipe down with white spirit, being sure to remove any excess sanding dust before applying Ronseal All Surface Primer
Always do a small test area to assess colour, compatibility and end result. Follow the manufacturer’s instructions on the tin at all times. Make sure you choose a warm, dry day (above 10℃). Stir well before use.
Using a good quality synthetic bristle brush, apply the primer in the direction of the wood grain
Apply 2 coats, allowing 4 hours drying time between coats
The primer will be touch dry in 2 hours, but allow 4 hours before applying a top coat
