APPLICATION DETAILS

Application conditions

The surface to be painted must be dry, the temperature of the air at least +5º C, and the relative humidity of the air below 80 % during painting and drying.

Preparation

Remove weathered grey wood surface mechanically. 
Untreated surface: 
Clean untreated wood surface from dirt, mould and loose particles. Wash surfaces with Maalipesu Cleaning Agent or with Homeenpoisto Mould Removal, if necessary. Remove loose resin from wood knots. 

Prime bare exterior wood surfaces with Valtti Plus Base or Valtti Pohjuste Priming Oil. 

Surface treated previously with a lacquer or translucent finish: 
Remove loose lacquer and putty from previously treated surface. Wash surfaces with Maalipesu or Homeenpoisto Mould Removal, if necessary. Sand glossy surfaces until matt and round sharp corners. Remove sanding dust. 
Interior wood work: fill holes and cracks with Spakkeli Wood Putty and sand the filled areas. 
Treat exterior bare wood surfaces with Valtti Plus Base or Valtti Pohjuste Priming Oil. 

Apply Presto Window Putty for window frames. Note! Unica Akva Lacquer can't be applied on top of silicone putties or on surfaces contaminaned with silicone. 

Painting

Stir Unica Akva Lacquer thoroughly before use. Apply with a brush 1-2 times, on new surfaces 2 times. 
On large surfaces it is best to apply the lacquer first with a short-napped roller and then smoothed out at once with a brush. Do not let the edges of the stripe get dry. Unica Akva Lacquer can be thinned for brush application with max. 5 % of water. 
The lacquer dries quickly and it is recommended to do the work in strips. The best application tools are synthetic fiber brushes that have multi-branched bristles. 
Treat visible wood end-grains carefully. 

Maintenance treatment: 
Unica Akva Lacquer can be maintenance treated with Unica Akva Lacquer. See Pretreatment. 
 

Cleaning of tools

Remove excess lacquer from the tools. Wash them with soap and water. Tikkurila Pensselipesu is recommended for removal of hardened lacquer.

Maintenance instructions

The product achieves its final hardness and durability at the earliest after 
2 weeks under normal conditions, therefore the surfaces must be handled with care during this time. If the surfaces need to be cleaned soon after finishing, clean them lightly with a soft brush, damp cleaning cloth or mop. 

At the earliest after 2 weeks from finishing the surfaces can be cleaned with Huoltopesu (1 part Huoltopesu in 10 parts of water). Very dirty surfaces and stains can be cleaned with a stronger Huoltopesu solution (1:1). After washing rinse and let dry.
