Surface preparation

  1. Step 1
      Sand dressed timbers to a uniform, smooth surface. Ensure the timber is dry and free from all dirt, dust, wax and oils. Clean oily timbers, such as Brushbox, Spotted Gum, Cypress or Tallowwood with methylated spirits and allow to dry.
      Note: Do not use steel wool on timber to be coated with UltraClear Interior as severe staining will occur.
      Clean surface with warm water and household detergent. When dry, sand to a uniform, dull surface. Vacuum and wipe off dust. Check for adhesion by applying UltraClear Interior to a small test area. Allow to dry for twelve hours then firmly press a strip of sticky tape over the section coated and rip off quickly. If the coating is removed sand back to bare timber and remove sanding dust. If the coating is not removed, sand the test area back to a uniform dull surface, remove sanding dust and proceed.
      Note: If the existing finish is wearing back to bare timber, it must be thoroughly removed before continuing. To remove coating sand, or use a combination of Intergrain Liquid 8™ Timber Stripper and sanding.
  2. In humid, tropical or mould susceptible areas timber should be treated with Intergrain TSS™ Mould Preventer prior to coating. TSS Mould Preventer should be left for a minimum of four hours before applying UltraClear Interior.
  3. Nail holes and surface defects should be filled with Intergrain Woodblend™ Wood Filler after the first coat of UltraClear Interior. Do not use Linseed Oil putty.

  2. Apply a minimum of two generous coats of UltraClear Interior with a quality brush or spray.
  3. Maintain a wet edge to avoid lap marks and an uneven finish.
  4. To aid application, soak the brush in water and remove surplus before loading with UltraClear Interior.
  5. Allow a minimum of three hours drying between coats. Sand lightly with fine grit sandpaper to remove any raised grain.
