Application conditions
The surface to be treated must be dry The temperature of the air has to be at least +5 ˚C, and the relative humidity of the air below 70 % during application and drying of the surface. Do not work in strong sunlight or damp and cold weather. Plan the work so that the lacquer film will have enough time to dry before evening dew.
Untreated surface:
Remove dirt and dust from new wooden surfaces. Wipe hardwood surfaces with White Spirit before treatment. Always prime bare exterior wooden surfaces with Valtti Base priming oil prior to applying lacquer.

Previously treated surface:
Wash down the surface with Cleaning Agent (Maalipesu) and rinse carefully with water. Remove old/loose lacquer with scraper. Sand down surface and remove the sand dust.
Stir the lacquer well before use and frequently during use. Prime new surfaces with Unica Super 90 gloss thinned with 20 % White Spirit. If you want a coloured surface, tint the priming lacquer to the same colour with the finishing lacquer. Finish evenly by applying 1-2 thin coats of unthinned lacquer. Apply evenly 1-2 thin coats of unthinned lacquer on previously treated surfaces without priming. Sand down lightly between each coat.
Cleaning of tools
Clean the tools with White Spirit 1050 or with Tikkurila Pensselipesu (Tool Cleaner).
Maintenance instructions
Not earlier than 1 month after treatment: Clean the surface with neutral cleaning agent (pH 6-8) using smooth brush, sponge or cleaning cloth. Clean very dirty surfaces with lightly alkalic cleaning agent (pH 8-10) using e.g. cleaning cloth, mop or sponge. Rinse the surface carefully with water.

The surface achieves its final hardness and durability after few weeks (1 month) under normal conditions, therefore the surface should be handled with care during that time. If the surface has to be cleaned soon after treatment, use smooth brush, damp cleaning cloth or mop.
Maintenance treatment
Observe the condition of the exterior surface and recoat when necessary. Longer maintenance interval can be obtained with a tinted product compared to a colourless product. Surfaces lacquered with Unica Super can be maintenance lacquered with Unica Super or same kind of solvent-borne lacquer.
