Preparation

Ensure the surface to be coated is clean and free from grease

• Lightly sand wooden surfaces with 80/120 grit for vertical, 60/80 grit for horizontal surfaces.
• Remove any moss, mould, lichen and carbon deposits with a sprayer or specially designed cleaner and stiff brush.
• Fungus, pollen or spores not removed and trapped below the clear varnish will discolour the surface of the timber when exposed to moisture.
• New or bare wood should be lightly sanded and cleaned with white spirit.
• Previously varnished surfaces if in sound condition, clean down to remove dirt, grease, oil and wax polish. If the existing varnish is in poor condition, remove it completely.
• Remove any poorly adhering or defective varnish by scraping back to a firm edge.
• Fill all joints, Cracks, and nail holes with a good quality Polyurethane or acrylic prior to coating.
