Wet rooms and damp areas

Instructions - Wet and damp interior spaces

The Feelings Watertight method complies with the waterproofing requirements of C2. Other surface treatment methods mentioned here are intended for damp spaces.


Before treatment

  • The air, surface to be treated, and paint or lacquer temperature must all be at least +5°C. Relative humidity must be below 80%.
  • The relative moisture of the wood must be below 16%. NB! Adequate humidity makes it easy to apply water-borne products, but prolongs their drying time.
  • Always read the instructions on the product label before use.
  • Undercoat new panels before fitting. Ensure that the undercoat is dry.
  • Paint the panel tongues and grooves thinly so that the paint dries well.
  • Choose an undercoat and topcoat of the same colour.
  • When treating wood surfaces with semi-transparent finishes, the final colour of the wood depends on its species, hardness, and original colour, and the number of times it has been treated. Make a small test application first to ensure the final colour!
  • For an even finish, always apply semi-transparent finishes in continuous strokes parallel to the grain.

During treatment

  • Stir products thoroughly both before and during application.
  • If you are painting an entire room, begin with the ceiling and then paint the walls.
  • Dry indoor air can cause water-borne paints to dry too quickly during painting.

  • If you continue painting the following day, put the paint roller or brush in a plastic bag and seal tightly overnight.

After treatment

  • Ensure adequate ventilation.

  • Let the products dry properly before use. It's not enough to let just the surface dry. Depending on the product and thickness of the coat applied, final curing can take anything between a few days and two weeks.

  • If there is any paint or lacquer left over, put the lid carefully back on the can to form a tight fit. Turn the can upside down for a moment to make the lid airtight. Opened and/or tinted products cannot withstand prolonged storage.

  • Take liquid paint waste to a hazardous waste collection point. Empty or dry cans can be taken to a recycling point or to a public waste disposal site.
