How linseed oil dries or when it is possible to continue working ?

Classification material

Drying - penkoobrazovatel is made on the basis of vegetable oil and passed a special treatment (long overheating heat or oxidation).Also it added driers and solvents that are used in the manufacture of paints, varnishes, primers and putties.Linseed oil is used as a primer wood and other porous materials prior to painting, for the manufacture of plastering compounds, as well as a separate decorative covering.

By their classification they are:

• Natural;
• semi-natural;
• Combined;
• Synthetic.

Depending on what class linseed oil, it has a period of drying.Knowing the drying time of linseed oil of a particular class, you will be able to work with this material much better.So, if it is dry enough, and you begin to paint the object, the coating will be bad to go to bed and eventually begins to crack.

Note!All kinds of varnish, except natural, a part of have bystrovosplamenyayuschiesya solvents, making them explosive and flammable.

natural and semi-natural varnish

Natural linseed oil is made by processing vegetable oils (linseed, sunflower, tung and others), which are in the process of drying.This material incorporates virtually no solvents.Linen natural drying oil - is a transparent, light and oily liquid that is made from flax oil and desiccant.It is used for the following purposes:

• primer wood, metal surfaces;
• For breeding fillers, putties and paints;
• to work on the color of floors, window frames and doors.

its drying time at a temperature of 20 degrees is not more than 24 hours.The same drying time of linseed oil and hemp.It is a dark oily liquid.It is used for the same purposes as linen.Sunflower oil varnish dries slowly and after 24 hours still slightly tacky.Its elastic film, but the strength, hardness and resistance to water of less than linen and hemp.

seminatural drying oils are the product of a strong heat treatment of sunflower oil and driers containing 55% condensed oil and 45% of volatile solvents.Their technical characteristics allow to use them in combination with other materials in order to obtain high-quality paint coatings.The film has good gloss, high hardness and water-repellent effect.

Important!Seminatural drying oils are not suitable for floor painting.

Combined and synthetic varnish

combined drying oil - a product of dehydration and polymerization of drying oils.In general, they are used for the production of paints pastes.Available brands K-2, K-3, K-4 and K-5.They dry for 24 hours.

synthetic drying oil - a dark liquid produced by the oxidation of shale oil, which was dissolved in xylene.On the complete drying it needs at least 24 hours, resistant to atmospheric influences.This is the cheapest linseed oil, it is used for cultivation of painting dark colors and for minor paint work in the room.Use it only in well-ventilated areas.This linseed oil does not dry as well as other species.It weakly impregnated, and most of the film remains on the surface.

Important!Not suitable for painting subjects of household use and floors.

is used for the following purposes:

• Priming concrete surfaces;
• Preparation fillers and putties;
• Priming metal surfaces indoors;
• for impregnating wood in outdoor applications;
• To consolidate and update the old coatings.
