Information
The main component of tung oil are olejostearové acid derivatives containing predominantly conjugated double bonds, which influence compared with linseed oil different properties at drying and the application.The thus practically differs from linseed oil, tung? At the same resistance to the effects of surface impregnated wood are enough layers 3-4, with linseed oil is required to deposit 10-20. Surfaces with tung oil also non-yellowing over time and more resistant to water. Drying for 1 to 2 days, linseed oil after about 1 week. Tung oil creates more flexible after drying impregnation, which is also used in paints wooden boat (the major component of the so-called Danish oil). Surfaces with tung oil are usually also declared as suitable for contact with food and toys for children. Surfaces are resistant not only water but also alcohol and food acids and alkalis. Unlike the linseed oil surface, the surface of tung oil more resistant molds.
This line strengths outweigh higher cost of tung oil compared with linseed. Tung oil is darker and more durable than linseed oil. Tung oil can be mixed with linseed oil.
As with tung oil works?
Dry surfaces before applying a fine grind (with the grain of the wood) and thoroughly cleaned. Less absorbent surfaces are first impregnated solution of tung oil and turpentine or white spirit (1:1), respectively. other suitable solvent. It is performed by applying the best and smear on the surface of textile materials. After the application is allowed to stand 20 to 30 minutes to soak a clean cloth and then wipe off excess coating. Another deposition is carried out after drying prior-usually after 24-48 hours, with many sajúcich documents and a day later. Suitable 3-4 layers. The last is usually already thinned.
