Application conditions

The surface to be painted must be dry i.e the moisture content of the wood shall not exceed 20 %. During painting and drying, the temperature of the air must be at least +5 ºC, and the relative humidity of the air below 80 %.


Untreated surfaces: 
Remove all dirt, mould and loose material from untreated or industrially primed wood surface. Wash dirty and mouldy surfaces with Tikkurila Mould Removal solution according to instructions. Treat bare wood surfaces with Valtti Base or Valtti Akvabase priming oil at the earliest possible construction stage. Protect nail heads and other rusting metal parts with Rostex Super Metal Primer. Remove loose resin from knots. 

Previously treated surfaces: 
Scrape away loose paint, finish clean with a steel brush. Wash down dirty and mouldy surfaces with Tikkurila Mould Removal solution according to instructions. Treat bare wood surfaces with Valtti Base or Valtti Akvabase priming oil. Patch paint with Ultra Primer. 


Stir the paint carefully before use and thin with water max. 10 %, if necessary. Apply with wide paint brush or high-pressure spray gun and brush. Treat end-grain carefully. 
Top coat is recommended to be applied as soon as possible after priming, however latest within 10 months from priming. 
Finish 1-2 times with Ultra or Pika-Teho house paint depening on the colour difference of the substrate and the condition of the surface to be treated. 
Discoloration of paint may occur over knots and resinous areas present in the wood. Using a primer reduces discoloration.
