Surface Preparation

New timber and joinery should be clean, dry and smooth. Any knots should be cleaned off with methylated spirit. Rub it down with fine glasspaper, following the grain and removing any dust. Remove oil, grease, dirt or surplus glue to prevent these showing through the primer. Oily woods, such as teak or iroko, should be thoroughly cleaned with a cloth impregnated with white spirit to remove natural oils. Non-ferrous nails are recommended for fixing beading etc. Remove old varnish completely with Blackfriar Professional Paint and Varnish Remover and then treat as new timber. Any French Polishes must also be completely removed.
