Selder linseed oil paints can be used indoor and outside using a brush, a sprayer or a roller on all substrates - from wood to metal. They remain durable and fine practically forever when you prime and paint as described in this work manual and perform simple maintenance measures.
We produce the paints as zinc-based primer and as topcoats in semi-gloss and half sheen, in white and as tinting bases A, B and C for machine tinting using certified modern pigments. They’re available in all NCS and RAL tints as well as in our own tints. The hue is identical from one delivery to the next.
They differ from other linseed oil paints first and foremost in that the binder consists exclusively of drying oils. The other constituents of linseed oil do not dry and have been removed. The paints therefore have excellent drying properties, excellent durability and mould resistance. Read more on the TECHNOLOGY.
They differ from alkyd oil paints and other synthetic paints in that they penetrate the surface structure of the substrate, adhere permanently and “breathe”, i.e., are permeable to water vapour but not to liquid water. Therefore no condensation accumulates under the coat of paint and it doesn't flake off.
They are painted undiluted “straight from the can” to covering 70–120 μm, i.e., 0,07-0,12 mm thick coats, which gives 14-8 square meters per coat, usually applying one coat of LINSEED OIL PAINT PRIMER and two coats of topcoat, LINSEED OIL PAINT HALF SHEEN or LINSEED OIL PAINT SEMI-GLOSS.
Drying time: Less than 24 hours at 20 ⁰C / 68 ⁰F with good ventilation.
SIMPLE MAINTENANCE, NO NEED TO REPAINT
Selder’s linseed oil paints age slowly as the molecular chains of the polymerized binder gradually are broken down by UV radiation. When this happens, after a couple of decades in shaded locations in the North down to after a few years in sun-drenched locations in the tropics, the surface becomes matte and fades, the paint becomes chalky. A thin layer of Selder's LINSEED VARNISH OIL replaces the lost binder and instantly gives the surface its original colour and gloss. With this simple maintenance measure, the lifespan of the paint is unlimited. If maintenance is neglected for a long time, most of the binder is eventually destroyed, the paint cracks, a typical crocodile skin pattern appears and squares of paint start to come off the surface. Such surfaces can be seen on outdoor objects painted with linseed oil paint in the 19th century or during the first half of the 20th century.

WORK MANUAL FOR LINSEED OIL PAINTS
The work differs significantly both from painting with synthetic paints and with other linseed oil paints. READ CAREFULLY FOR A GOOD RESULT.
First read the summary and then check the parts that are of relevance to you in the TABLE OF CONTENTS below.
Selder's linseed oil paints remain durable and fine practically forever when you prime and paint as described in this work manual and perform the simple maintenance measures described below.
The paints are tinted to the desired NCS, RAL and our own colours on modern machines that use our tinting system.
The ordered colour is identical from delivery to delivery.
They can be painted with a brush, sprayer or roller on any surface - from wood to metal.
Water in the substrate and movements in wood due to significant variations in moisture cause the paint to flake off. Make sure that water does not get into the substrate and affects the painted surface from the back. Paint only on a dry substrate, on wood with a maximum moisture content of 12%, i.e., air dry. Impregnate wood that is exposed to water and moisture with Selder PRIMER OIL before painting as described below.
Porous substrates are pore-saturated with PRIMER OIL or LINSED VARNISH OIL before priming with LINSEED OIL PAINT PRIMER. Otherwise too much binder is absorbed into the substrate and too little is left in the pigment, the optical properties of the paint change, the colour fades and becomes matte and often blotchy.
First paint a covering but not thick coat of LINSEED OIL PAINT PRIMER, i.e., of 70-120 μm (0.07-0.12 mm) thickness. It adheres particularly well as it is especially greasy, and it prevents the growth of mould, algae and lichens for decades on the finished paint surface as it contains 0.5 kg of zinc oxide / litre. However, it is not as weatherproof as the topcoat paints.
Let the paint dry thoroughly between coats.
The paint dries within 24 hours at 20 °C / 68 °F and good ventilation; dark, clear shades slightly slower.
Then paint two covering coats of LINSEED OIL PAINT SEMI-GLOSS OR SEMI-MATTE of similar thickness.
Wash used brushes, tools and containers with strong soft soap before the paint dries.
Rinse sprayers with white spirit.
WARNING: RISK OF SELF-IGNITION The paint contains oxidizing fatty acids. Cloths and other porous materials moist with paint must be immersed in water without delay. Painted or oil treated surfaces do not ignite spontaneously - the risk only applies to fibrous materials.
