APPLICATION INSTRUCTIONS

Application conditions
The surface to be treated must be dry and the moisture content of the wood below 20%. During painting and drying, the temperature of the air, surface and wood finish must be at least +5 ºC, and the relative humidity of the air below 80%. The working properties are at their best in calm, cloudy dry weather in temperatures of +10 to 20 °C.
Surface preparation
Untreated surface:
Clean the surface from dirt, dust and loose material with a steel or scrubbing brush. Wash moldy surfaces with Tikkurila Homeenpoisto according to the instructions. Prime surfaces at the earliest possible stage of construction with Valtti Pohjuste or Valtti Plus Base. Protect plants from splashes of primer.
Surfaces that have previously been treated with a semi-transparent product:
Remove loose material and wood that has turned gray with a scraper and/or steel brush. Clean the surface and wash with Homeenpoisto mold removal, if necessary. Prime bare wood surfaces with Valtti Pohjuste or Valtti Plus Base. If a clear possibly glossy film remains on the wood surface, roughen the surface by sanding.
Reserve enough tinted Valtti Plus Kesto for one uniform surface, mixed in one can, to avoid possible color differences. Stir thoroughly before use and from time to time during use.
Apply Valtti Plus Kesto evenly and continuosly along the length of a log or few boards to avoid overlapping. The product dries quickly. Apply the product enough to form an even, thick layer. Treat the end surfaces of the wood with special care.
Apply two coats on new, primed surfaces and in maintenance painting 1-2 coats, depending on the condition and earlier treatment of the old surface. The surfaces previously treated with a thin, wood absorbent product usually demand two treatments.
Check the condition of the treated surface and perform maintenance treatment as necessary, when the surface of the stain starts to wear out. The maintenance interval is affected by the location and direction of the object as well as weather conditions.

Cleaning of tools
Clean the tools with water and soap Tikkurila Pensselipesu Tool Cleaner is recommended to remove slightly hardened paint.

Maintenance instructions
Handle the painted surface with care as the product achieves its final hardness and durability in normal conditions in about four weeks. If a surface needs cleaning soon after treatment, use a soft brush, a damp cloth or a mop.
After one month from painting, a dirty surface can be cleaned with Huoltopesu (mix 1 part of Huoltopesu with 10 parts of water).
Clean stains and very dirty surfaces with a stronger Huoltopesu solution (1:1). After washing rinse with water and let dry.

Maintenance treatment
Valtti Plus Kesto can be maintenance treated with Valtti Plus Kesto. See Pretreatment.

Environmental and waste disposal
