What are tannins?
Exterior Timber Preparation
Timber, as a product of nature, is subject to fungal attack, degradation from UV light, expansion and contraction with varying moisture levels, variations in density and oil, tannin and resin content. All these characteristics impose considerable demand on timber finishes. Preparation is vital for achieving the longest life span possible from your Intergrain Timber Finish.
Step 1
New Bare Timber
Allow timber to weather for approximately 4 - 6 weeks until leaching of the tannins and oils has ceased. After this period, proceed to Step 2.
Previously Painted, Stained or Oiled Timber
All paints and coatings that seal the surface must be thoroughly removed back to bare timber. A combination of Liquid 8 and power washing, or sanding is recommended. For previously oiled or stained surfaces that do not seal the surface commence at Step 2.
Weathered, Grey or Mould Affected Timber
For best results, sand timber back to a fresh surface. Remove sanding dust, then proceed to Step 2
Step 2
Clean timber with Reviva closely following label instructions. Ensure surface is rinsed clean and allowed to thoroughly dry.
Step 3
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.
Step 4
In humid, tropical or mould susceptible areas coat timber with TSS. TSS should be left for 24 hours before applying your chosen timber finish. When using DWD, timber must be primed with Dimension 4.
Step 5
Fill nail holes and surface defects with Woodblend as directed on the selected timber finish can instructions.
Always refer to the surface preparation and application instructions provided on the back of the Intergrain Timber Finish product before commencing your project.
