Weathered Timber
Prepare exterior weathered or grey timber by cleaning thoroughly with Woodclean as per the instructions. Sand to a smooth surface and remove all sanding dust before coating.
Previously Coated Timber
Previously coated surfaces need to be taken back to bare timber by sanding timber to a smooth surface. Remove all sanding dust before coating.
New Timber
Allow new timber to acclimatise in its final position for 4-6 weeks. Coat with Feast Watson Timber Primer to protect it from stains and warping during the acclimatisation period.
Prepare exterior timber for coating with Feast Watson Woodclean as per the instructions.

Weatherproof Varnish should be stirred thoroughly before and during application with a flat blade stirrer taking care not to introduce bubbles. Apply Weatherproof Varnish using a brush, roller or spray. If spraying Weatherproof Varnish may be thinned by using 10% mineral turpentine. If applying by roller, use a short nap (5mm) mohair roller. Ensure edges and end grain are fully coated. Apply minimum three coats. Four or more coats may be applied for extra durability, or when the coating has been thinned. Allow 12 hours drying between coats. Sand lightly between coats. The final coat should be applied within 30 hours of the previous coat to ensure timber is protected.
Maintenance
Regularly monitor the surface for signs of colour loss or surface defects. When required, lightly sand the surface and remove dust. Re-coat with additional coats of Weatherproof Varnish as per application instructions.
