ALWAYS READ THE PAINTING ADVICE ON THE TIN!

New, untreated timber of pine or spruce should first be primed with a coat of Falu Rödfärg diluted with 15-20% water. This should be followed by a coat with undiluted paint. Cover thinly, the paint should be worked into the wood. Coats that are too thick can cause the paint to flake.
Cover over foundations, down pipes, paving slabs and windows with board or plastic. If possible leave the cover in place for about 1 week if there is a risk of rain. The paint can run in strong rain, we therefore recommend that paving slabs are not laid right up to the house wall but leave a couple of decimetres with an alternative filling material.

Weather
Do not apply to surfaces that have been exposed to strong sunlight or to wet wood (the moisture content of the wood should be less than 15%, ask your timber supplier). The lowest air temperature for painting is +5°C. Also avoid painting if there is any risk of night frost. If there is a risk of mildew spores in the wood, it should be treated with an anti-mould agent.

Discolouring mould (black dots)
Use some form of facade wash, anti-mould agent, and follow the instructions on the bottle. Available at paint retailers.

It is important to wash off algae or mould before painting! If there is any mould left on the frontage the paint acts as nourishment for the mould and the wall is soon covered in black dots again.

How does mould occur?
Wood must be stored in a protected place. If it is lying directly on the ground or under a tarpaulin there is a major risk of mould starting to grow. Rot can also develop if the timber is stored wet, out in rain. Moisture in the soil also contributes to mould starting to grow.
Paint is not a means of control and cannot provide guaranteed protection against mould.
The problem has increased in that we are having wetter summers and longer periods of warmer and damper autumns and winters.

To bear in mind
Check that the frontage is free of mould and/or algae. Wash the frontage as per the above if necessary.

Falu Rödfärg should be applied in thin coats that are worked into the wood. If it is too thick there is a risk of the paint flaking when it has dried.
Does the paint seem too thick? Dilute it with a small amount of water.
Does the paint seem too thin? The consistency of the paint can vary, this is usually due to the quality of the starch that is used as binder. The paint is equally good to use.

Repainting
It is important that the coat of paint has time to age and start to whiten (the pigment becomes loose on the frontage) before you repaint. If you repaint too often there is a risk of the coat of paint becoming too thick and the wall can start to flake.
When you have to repaint, it is sufficient with one coat of Falu Rödfärg.
