APPLICATION DETAILS

Application conditions

All surfaces to be painted must be dry, the moisture content of the wood below 20%, the temperature of the air, surface and wood finish at least +5°C , and the relative humidity of the air below 80% during painting and drying. The working properties are at their best at a calm, cloudy dry weather day with temperature +10 - + 20°C.

Preparation

Untreated surfaces:
Clean surfaces from dirt, dust and loose material with steel or scrubbing brush. Wash moldy surfaces with Tikkurila Homeenpoisto Mould Removal or Tehopesu Super Clean according to instructions. Prime surfaces at the earliest possible stage of construction with Valtti Pohjuste or Valtti Plus Base. Protect plants from splashes of priming oil.

Surfaces previously treated with semi-transparent product:
Remove loose material and wood turned grey with a scraper and/or steel brush. Clean the surface and wash with Homeenpoisto Mould Removal or Tehopesu Super Clean, if necessary. Prime bare wood surfaces with Valtti Pohjuste or Valtti Plus Base. If a clear possibly gloss film remains on the wood surface, remove it or at least sand carefully.

Make sure that timber cladding, weatherboarding and timber glazing beads, etc. are adequately fastened with non-corrosive fixings. Valtti Akvacolor 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

In as early construction stage as possible a priming coat of Valtti Pohjuste or Valtti Plus 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.

Treatment

Reserve enough tinted Valtti Akvacolor for one uniform surface, mixed in one can, to avoid possible colour differences. Stir thoroughly before and during use. Apply Valtti Akvacolor evenly and continuosly along the length of a log or few boards to avoid overlapping. Apply liberally on the end grain. Apply two coats, on sawn and log surfaces thin coats. Always use a tinted product for the treatment of a new surface. Check the condition of the treated surface and make maintenance treatment when necessary. The maintenance interval is affected by the location, point of compass and weather conditions. Check the condition of the timber and the functionality of the log structure before applying the finishing coat.

Cleaning of tools

Clean with water and soap immediately after use. Rinse with water. Tikkurila Pensselipesu (Tool Cleaner) is recommended for removal of hardeded finish.
