Surface Preparation

New or Bare Timber: 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. Previously Finished Timber: 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 24 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. If the coating is not removed, sand the test area back to a uniform dull surface and proceed. Note: If the existing finish is wearing back to bare timber, it must be thoroughly removed before continuing, a combination of Intergrain Liquid 8 Paint Remover and sanding is recommended. In humid, tropical or mould susceptible areas timber should be treated with Intergrain TSS prior to coating. TSS should be left for 24 hours before applying UltraClear Interior. 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. APPLICATION Do not apply by roller. Stir thoroughly before and during use with a flat blade stirrer. Do not shake or thin. If project requires more than one can of tinted UltraClear Interior, mix all cans together in one large container to ensure colour uniformity. Apply a minimum of TWO generous coats of UltraClear with a quality synthetic or pure bristle brush or by spray (HVLP or airless). Take care to apply sufficient product to edges and end grain. Maintain a wet edge to avoid lap marks and an uneven finish. When applying by brush, lay off in the direction of the grain. To aid application, soak the brush in water and remove surplus before loading with UltraClear. Do not overwork as this can result in poor appearance. When spraying ensure adequate film build is applied to achieve maximum durability. It is normal for UltraClear Interior to have a milky appearance when first applied, this disappears on drying. Allow a minimum of 3 hours drying between coats. Sand lightly with fine grit sandpaper to remove any raised grain. If coating large surfaces in warm conditions, wash the brush out at regular intervals to allow smooth application. If using tinted UltraClear Interior, the colour will become deeper with each application. If desired colour is achieved after one coat, apply untinted UltraClear Interior to complete the required number of coats. MAINTENANCE Clean using water and a non-abrasive household detergent. To ensure minimum preparation when recoating, surfaces should be recoated before UltraClear Interior has worn away to expose bare timber. Clean to remove any waxes or polishes. When dry, sand to a uniform dull surface and remove dust. Apply 1-2 coats following application instructions. Where UltraClear Interior has worn away to expose bare timber it must be thoroughly removed and the surface prepared as per instructions for new timber. A combination of Liquid 8 and sanding is recommended.
