New timber:
Sand timber 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 Exterior as severe staining will occur.

Grey and weathered with no previous coating:
Sand timber back to a fresh surface, and remove sanding dust. Note: The rounding of sharp edges with sandpaper is highly recommended to maintain coating film thickness.

Paints, varnishes or coatings in varied condition:
All paints and coatings that seal the surface must be thoroughly removed back to bare timber. To remove coating sand, or use a combination of Intergrain Liquid8™ Timber Stripper and sanding.

All composites & bamboo substrates:
Sand, remove sanding dust, then check for adhesion by applying UltraClear Exterior to a test area, approximately 250mm x 250mm. Allow to dry for twelve hours then firmly press a strip of sticky tape over the coated section and rip off quickly. If the coating is removed do not proceed as the surface is not suitable.

Important: If mould is present or if timber is in a mould prone area, use Intergrain UltraPrep Mould Killer to remove surface mould effectively as the first step of preparing the timber for coating

Nail holes and surface defects should be filled with Intergrain Woodblend™ Wood Filler.

Conduct a routine 12 monthly maintenance inspection. Note: For marine environments conduct a 3 monthly maintenance inspection.

Best protection of the timber and ease of maintenance is ensured if UltraClear Exterior is recoated before deterioration of the coating and timber underneath occurs.

First indication 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, sand affected areas back to bare timber, remove sanding dust and recoat.

For large weathered areas remove UltraClear Exterior by sanding, or use a combination of Liquid 8 Timber Stripper* and sanding.

To recoat UltraClear Exterior which is in good condition, lightly sand, remove sanding dust and apply one coat of UltraClear Exterior.
