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. Fill nail holes and surface defects with Intergrain Woodblend Wood Filler after applying the first coat of UltraDeck. APPLICATION Do not apply by roller. Stir thoroughly before and during use with a flat blade stirrer Do not thin. If project requires more than one can of tinted UltraDeck, mix cans together in one large container to achieve colour uniformity.. Apply TWO coats of UltraDeck using a quality synthetic or pure bristle brush, pad applicator or spray (HVLP or airless). THREE 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. 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 spraying, backbrush after each section is coated to ensure a uniform finish. Apply along the lenght of the board including exposed edges and end grain. If necessary, sand lightly between coats to remove any raised grain. If using UltraDeck in conjunction with UltraGrip, DO NOT sand between coats. MAINTENANCE First indication of the need for recoating will be observed as signs of dryness and loss of colour. Clean the timber thoroughly with Reviva and recoat with UltraDeck following application instructions.

Clean Up

So, for best results on Spotted Gum use Intergrain Nature's Timber Oil or Intergrain NaturalStain.
