Specifications
Preparation
Surfaces must be clean, dry, and free from grease, dirt, oil, wax, all loose material and surface contamination. Use recommended Tikkurila products for mould removal and cleaning. Fill cracks, joints, nail holes, etc., with a good quality wood filler. Ensure that existing glossy, previously stained and filled surfaces are thoroughly flatted down so as to ensure adequate penetration of Valtti Extra in to the surface of the wood. Make sure that timber cladding, weather-boarding and timber glazing beads, etc., are adequately fastened with non-corrosive fixings. Valtti Extra is not recommended for use with linseed oil putty. Good quality non-setting glazing compounds which form a protective skin should be used in accordance with manufacturers instructions. Particular attention with regards to preparation should be given to wood such as Oak, Teak, Cedar, Douglas Fir, Mahogany and Idigbo, etc., which contain oil and water-soluble tannin which may impair the drying, hardening or adhesion of surface coatings.
Priming
A priming coat of Valtti Base should be applied to all exterior wood which has not been pre-treated or vacuum impregnated with an approved wood preservative. Apply liberally on end-grain.
Application
Methods: brush or spray. For airless spray: use a 0.009" – 0.013" (0.23 – 0.33mm) spray tip. Thinning: Valtti Extra requires no thinning.
Painting conditions
All surfaces to be painted must be dry, the moisture content of the wood below 20%, the temperature of the air at least +5 deg. C, and the relative humidity of the air below 80%.
Coverage
Smooth wood:10-12 m2/litre per coat. Sawn wood: 4-8 m2/litre per coat. Actual spreading rates will depend upon many factors including texture, porosity and moisture content of the substrate.
Drying times
At 23 deg. C and 50% relative humidity of the air: normally touch-dry after 8 hours and recoatable after 24 hours.
Cleaning of tools
Clean immediately after use with white spirit.
Maintenance
Depending upon exposure and elevation, one coat of Valtti Extra is normally sufficient after 3-5 years.
