Surface Preparation

New Bare Timber: Allow timber to weather for approximately 4-6 weeks until leaching of the tannins and oils has ceased. After this time, clean timber with Intergrain Reviva, closely following label instructions. Previously Painted, Stained or Oiled Timber: All paints and coatings that seal the surface must be thoroughly removed back to bare timber. For previously oiled or stained coatings that do not seal the surface, clean timber with Intergrain Reviva, closely following label instructions. Weathered, Grey or Mould Affected Timber: For best results, sand timber back to a fresh surface. Remove sanding dust, and clean timber with Intergrain Reviva, closely following label instructions. Clean all timber with Intergrain Reviva Timber Cleaner, closely following label instructions. Ensure surface is rinsed clean and allowed to thoroughly dry. Test if the surface is ready for coating by sprinkling water on the timber. If the water beads on the surface, repeat the application of Reviva. If the water is absorbed into the timber, it is ready for coating. In humid, tropical or mould susceptible areas, new and cleaned timber should be treated with Intergrain TSS Timber Sterilising Solution before coating. TSS should be left for 24 hours before overcoated. Prime all new or bare timber surfaces with one heavy or two wet on wet saturating coats of Intergrain Dimension 4, taking care to seal all exposed end grain and joinery to prevent moisture absorption. Nail holes and surface defects shold be filled with Intergrain Woodblend Wood Filler. APPLICATION The UV absorber system in DWD will impart a transparent golden orange-brown tint. Test for colour suitability before proceeding. Do not apply by roller. Stir thoroughly before and during use with a flat blade stirrer. If project requires more than one can of tinted DWD, mix cans together in one large container to achieve colour uniformity. Apply THREE coats of DWD, taking care to apply sufficient product to edges and ends. FOUR coats will be required in extreme conditions such as full sun exposure, around pools and in humid areas, and may be required on porous timbers. Apply with a quality synthetic or pure bristle brush, pad applicator or spray (HVLP or airless). When applied at the correct application rate, the coating will have an opaque appearance which becomes transparent on drying. Do not brush out until tranparent, over brush or apply thinly as insufficient film thickness will compromise performance and durability. If necessary, sand lightly between coats to remove any raised grain. MAINTENANCE Annually conduct a routine maintenance inspection. Best protection of the timber and ease of maintenance is ensured if DWD is recoated before deterioration of the coating and timber underneath occurs. First indications of the need for recoating will be observed as patchiness or thinning of the surface coating on edges and areas where insufficient product has been applied. If small areas of timber have weathered through to cause deterioration of the coating, clean area thoroughly with Reviva, sand and recoat as for bare timber. For large weathered areas, remove existing DWD coating back to bare timber. This can be done with Intergrain Liquid 8 and power washing, or sanding. Coat as for bare timber. To recoat DWD which is in good condition, simply clean the surface with Reviva and apply one coat of DWD.
