    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 filler prior to coating

  • Application

    Always try the varnish on a test patch before embarking on the project to ensure you are happy with the finished results.

  • Stir well before use
  • Apply using a brush, roller or sprayer
  • Apply 3 coats in total allowing a minimum of 2 hours between each coat
  • On porous surfaces dilute the first coat with 10% water
  • Leave 16 hours for the finish to sure

  • Always follow the manufacturer's instructions found on the container
