Recipe: Oil Paint on Heavily-Used Wooden Surfaces (Interior and Exterior)

Oil paint is suitable for almost all indigenous wood species (except for highly resinous larch wood). Application on exotic wood can be problematic, because it can contain substances that may prevent the drying of the oil. In this case, we recommend pretests prior to the application! The new paint coat should to be protected from rain and dew for at least one week after the application. For the first three days (and nights), the temperature should not be below +12 °C (= 53.60 °F)! We recommend, the use of siccatives/desiccants for external application.

Processing

For priming the wooden surface, mix 1 part Hard Drying Oil (#79021) and 1 part Pine Turpentine (#70010). Apply the half-oil thickly and richly onto the raw wooden surface. After one hour you can take up excess liquid with a lint-free cloth. Gently sand with sandpaper (granulation 150) when dry. Consumption rate is about 100-120 ml/m2. Step 1#336: For priming the wooden surface, mix 1 part Hard Drying Oil (#79021) and 1 part Pine Turpentine (#70010). Apply the half-oil thickly and richly onto the raw wooden surface. After one hour you can take up excess liquid with a lint-free cloth. Gently sand with sandpaper (granulation 150) when dry. Consumption rate is about 100-120 ml/m2.
For the first, lean coat, dilute 1 part oil paint paste with about 1 part Pine Turpentine in order to make it spreadable, then apply thin and evenly. For better drying, you should add siccative to the oil paint (7 milliliters of siccative per 1 liter of oil paint paste). Sand with sandpaper (granulation 150-220) when dry. Consumption rate is about 100 ml/m2. Step 2#360: For the first, lean coat, dilute 1 part oil paint paste with about 1 part Pine Turpentine in order to make it spreadable, then apply thin and evenly. For better drying, you should add siccative to the oil paint (7 milliliters of siccative per 1 liter of oil paint paste). Sand with sandpaper (granulation 150-220) when dry. Consumption rate is about 100 ml/m2.
For the second, semi-rich coat, mix 1 part Hard Drying Oil and 1 part Pine Turpentine. With this mixture, dilute the siccativated oil paint paste to spreadability (take about 1 part of the mixture and 1 part oil paint paste). Apply the paint thin and evenly. Sand with sandpaper when dry (granulation 220-360). Consumption rate is about 80 ml/m2. Step 3#346: For the second, semi-rich coat, mix 1 part Hard Drying Oil and 1 part Pine Turpentine. With this mixture, dilute the siccativated oil paint paste to spreadability (take about 1 part of the mixture and 1 part oil paint paste). Apply the paint thin and evenly. Sand with sandpaper when dry (granulation 220-360). Consumption rate is about 80 ml/m2.
For the final, rich coat, dilute the siccativated oil paint with the hard dry oil with a mixing ratio of about 1:1 in order to make the paint spreadable. Apply thin and evenly. Consumption rate is about 60 ml/m2. Please respect the following waiting times when applying oil color: The prime coat requires 1 day drying time. All following layers require 2 days drying time. Step 4#374: For the final, rich coat, dilute the siccativated oil paint with the hard dry oil with a mixing ratio of about 1:1 in order to make the paint spreadable. Apply thin and evenly. Consumption rate is about 60 ml/m2. Please respect the following waiting times when applying oil color: The prime coat requires 1 day drying time. All following layers require 2 days drying time.

General Safety Procedures

Note

The consumption information and recipes given above contain circa measures. Consumption may vary on different surfaces and depending on coat thickness and the oil paint used! Paint the oil color on dry would only and avoid dew affected areas. Warm wood which is exposed to sunlight will bring out oil color at its best. Products containing linseed oil and oil contaminated cloths dry by oxidation, which is an exothermic reaction that accelerates as the temperature of the oily substances/textiles increases. This is why we recommend that all oil contaminated cloths and rags etc. be kept in closed metal buckets. Dispose carefully.

We assume no liability for the processing instructions described above. In any case, we recommend the production and evaluation of sample surfaces.
