Surface preparation

The wood must be free from wood dust and contamination. The moisture content of the wood should not exceed 18%. All softwood and non-durable hardwood for exterior use should be treated with TEKNOL AQUA 1410-01 wood preservative.


After on-site cutting the specified loading rate must be re-instated.

Application conditions

The temperature of the air, the surface and the paint shall be above +10°C and the relative humidity of the air below 80% during the time of application and drying. The best result is achieved when the temperature of the air is between +23°C and +38°C, the relative humidity of the air is 50-70% and the ventilation good. Stir the paint thoroughly before use, preferably using mechanical stirring. For all coated solid wood or wood-based panels, a non-marking protective layer of minimum 1.5 mm thickness (e.g., polyethylene film) is recommended to be used between coated surfaces.


The best storage temperature is +10°C - +25°C. Must not freeze.
