Painting instructions

UULA LINSEED OIL PAINT

Traditional oil paint for exterior surfaces. The genuine UULA Linseed Oil Paint is made in the traditional way from pressed and boiled linseed oil and colour pigments. Boiled linseed oil, used as oxidative binder, ensures that the paint coat develops a water vapour permeate surface that is breathable with the wood. Water vapour evaporates through the paint so that the paint does not peel and the wood underneath does not decay. The paint dries slowly,which ensures good absorption and adhesion.

TINTING AND COLORS

Linseed Oil Paint is tinted with color pastes made from genuine color pigments. Colors can be chosen from Uula Traditional Color Chart and from our previous color charts.  Other colors are available on special orders.

APPLICATIONS AND CONDITIONS

Apply by paint brush or levelling paint brush. The surface must be dry and the moisture content of the wood below 15 %. The relative air humidity must be below 80 % and the temperature at least +10°C. Drying time At 20°C and <80 % relative humidity: tack free in 2–3 days, depending on the circumstances. A new coat can be applied after four days at earliest. Heat and light is required for the paint to dry (min +10°C).

PAINTING INSTRUCTIONS

Preparation:

Remove peeling and flaking old paint with a wire brush and scraper. Remove old paint as thoroughly as possible. Old, thick paint layers can be removed efficiently by using Uula Paint Remover. Wash dirty surfaces with Uula Paint Washing Agent and moulded ones with Uula Mould Cleaning Agent. Sand new planed surface to ensure adhesion.

Priming:

Previously painted exterior wood surfaces: Patch-prime with Uula Exterior Primer if necessary and treat the surface with Uula Anti- Mould Agent. For metal surface prime with anti-rust primer before painting. New exterior wood surfaces: Prime new exterior surfaces with Uula Exterior Primer. New, industrially primed wood surface does not need to be primed with Uula Exterior Primer or treat with Uula Anti-Mould Agent. If the surface is new planed timber, sand the surface to ensure adhesion or protect the surface with Uula Anti-Mould Agent and let the wood age for 1-2 years before painting.

Undercoat:

Paint the primed exterior surfaces with Uula Linseed Oil Paint thinned 10–15 % with Uula Oil Paint Thinner 166. Let dry for at least 3 days.

Finishing:

Paint tightly with thin layers. Make sure that the paint has dried and brush off dust and dirt. Thin the paint 10 % at maximum if necessary. (e.g. in cool conditions) Painting exterior metal surfaces prime with anti-rust paint, otherwise follow the instructions above.

Points to note:

  • Reserve enough paint for a large surface in order to avoid potential colour
    variations in different batches.
  • The paint must always be stirred well before and during use.
  • Check the colour before painting.
  • Do a test painting to a separate piece of wood e.g.
  • The paint must be applied thinly and tightly. If the paint coat is too thick it may wrinkle
    when drying. Also heating the paint makes the paint easier to be applied thinly.
  • The paint brush or levelling paint brush must be stiff enough.
  • Paint also the cross-sectional surfaces of the timber carefully.
  • It is distinctive of oil paints to turn yellowish in the dark.
  • Do not paint in the rain, in direct sunlight or a sun heated surface.
  • If the paint is sprayed to the surface, spread the paint with a brush after spraying.
  • If the painting of the surface is postponed to the next summer, protect the
    surface with Anti-Mould Agent.
  • If there is mould and dirt in the surface, the surface should be washed.
  • More detailed instructions for maintenance and cleaning can be found in our website
    www.uula.fi
  • In case of uncertainty, submit to the manufacturer or to a competent distributor before
    starting the painting process.
