Valuable tips for painting with linseed oil paint

  • In the first 24 hours after applying the linseed oil paint, it should be preferably not raining since the water droplets would settle on the surface and make the paint appear blotchy.
  • Linseed oil paint should be well spread out and be massaged into the wood, literally. If a too thick paint layer is applied, the paint would dry much slower for starters and, secondly, there is the danger of the paint getting wrinkles. Therefore linseed oil colours should be applied as thinly as possible!
  • Always use a dense brush with a large amount of strong bristles. A dense, strong brush made of pig hair is said to be very suitable. You can find the matching brushes in our Shop
  • The use of strong cleaning detergents (high pH values) can chemically alter linseed oil colours and make it unusable. Surfaces that are to be painted, should be sanded and dusted before painting. The proper tools needed for paint removal can be found in our Shop
  • It is recommended to prime highly absorbent surfaces with cold-pressed linseed oil before applying paint. This can also be found in our Shop.
  • Untreated wood should be treated with at least three layers of colour. The third and final coating actually prolongs the life of the paint.
  • Pigmented linseed oil paint is a natural product. Small differences in colour are therefore quite normal.
  • Linseed oil-soaked rags can be easily ignited. Therefore, they must always be kept in a bucket of water or in a metal container.

Practical Tips in dealing with Linseed oil paint

 

Practical Tips in dealing with Linseed oil paint The paint may be left out overnight or even stored longer time periods. To ensure paint quality, the orifice or bucket should be covered with plastic wrap. In this case the plastic wrap should be applied directly on top of the surface in order avoid contact with oxygen. Thus, the colour does not come into direct contact with oxygen and does not form a film layer. The plastic wrap should be peeled away before use and the paint thoroughly stirred. Used brushes can be stored well in a glass filled with cold pressed linseed oil or stored in water, if necessary. Be sure to shake off excess water or oil before re-using the brushes. Wrapping or rubbing them in a newspaper should usually suffice. Another effective way to clean the brushes would be the use of linseed oil soap. If chosen, please be sure to massage the “soap” well into the brush or brushes until it lathers. Then allow them to soak for one hour and rinse the brushes with clear, hot water. Important: first soap only, then water. Turpentine should only then be required only when the brushes have dried excessively. It is important to thoroughly wash out the brush, so that no soap residue in the brush is left behind. These could otherwise dissolve into the linseed oil paint and affect its quality. Not yet dried linseed oil stains on clothing can usually be removed by carefully applying linseed soap. In this particular case, the affected area should be dampened or moistened before be sure to allow the soap to soak in long enough.

The half-timbered building today embellish the image of many old towns and villages. One is surprised by the well-preserved variety of design details and decorative elements. Of course it varies regionally.

In recent years, these beautiful houses have come more into focus. Now the question of proper restoration, maintenance and upkeep of these important to maintaining buildings.

In the past few years the selection of suitable materials for the restoration of half-timbered houses has become very important. Half-timbered houses have been repaired and maintained for hundreds of years. However, in recent decades there have been a number of new materials and methods that have brought more harm than good.

Since wood, when exposed to changing weather conditions, including moisture and strong Ultra-violet sun exposure, can have a great impact on the overall structure within only a few years. For this reason, it is important to use a paint material that protects the wood while keeping the moisture level to a minimum. This can be achieved be using a vapor-permeable and resilient color that can follow the natural shrinkage or changes in the wood, including its dimensional changes.

Pure linseed oil colors without chemical additives, solvents or resins have traditionally been used traditionally for half-timbered houses and are now being increasingly used. Its small molecular size delivers very good penetration and high resistance to weathering conditions. Linseed oil colors remain flexible and are not prone to flaking. The binding quality of linseed oil paints (linseed oil) dries chemically, ie Linseed oil takes oxygen from the air and builds a web-like structure, thereby building a very elastic paint film. By choosing a color with natural earth pigments, additional UV protection is ensured.

Since excessive moisture / wetness usually leads to wood rot, the moisture protection of the truss timbers are of particular importance. This is due to the fact that the lying and facing compartments tend to easily allow the moisture to enter the wood through cracks in the joints. It is a natural process. However, this moisture must be able to dry out easily. Therefore, you need a vapor-permeable material when painting. The water vapor permeability (described by the Sd value) of linseed oil colors is 0.879 to 1.584. That is linseed oil colors have enough permeability to ensure the wood will be water-tight through the entire wooden structure. Though they are also naturally open enough to allow water vapor to pass through to exit the wood. The thickness of the paint film is decisive for a low Sd value. It is therefore necessary to remove old coatings.

Linseed oil paints weather gradually, but only on the surface. If the loses its shine, it can be renewed with a fresh layer of boiled linseed oil.

In Scandinavian countries, you can find wonderful examples of century-old, yet well-preserved half- timbered houses. Linseed oil paints and lime coatings have a long tradition there and have been used through and through. The good properties of natural materials is known there and highly appreciated. The knowledge and experience with these materials have been passed on for generations.
