How to use Crystal Clear Exterior Varnish


Sand the wood using 120 grit paper. Wear a mask to avoid inhaling any dust. Don't use in temperatures lower than 10°C. Stir well before use and test on a small area to check you are happy with the finish. It's off white in the tin but it dries clear.


Use a synthetic brush and apply 3 coats in the direction of the grain. Leave 6 hours between each coat and lightly sand using 240 grit paper before the final coat.

Clean Up

Remove any varnish from your brush and wash in warm, soapy water. Don't put any left over varnish down the drain or into watercourses. Your local authority may have facilities to get rid of unused varnish.
