The diluted varnish at home?

homemade mixture of linseed oil

used for the production of oil and acrylic paints and for dilution.Also, some types of material used for impregnating and priming of wooden surfaces.For it is possible to make use of their own home.Consider how to make varnish.Natural

done by heat treatment at a temperature of 250 degrees Celsius with the gradual addition of driers.To do this, apply linseed, hemp and other refined drying oils.Driers are the lead-manganese or manganese-lead-cobalt linoleates.Polymerization is carried out in stainless steel reactors that are suitable for administration driers.

Castor oil varnish made by the polymerization of castor oil and glycerol by esterification.Next, the resulting mixture is dissolved in white spirit with addition of siccative.The composition of this mixture is:

• 50% of castor oil;
• the prepared 46% castor oil;
• 4% mineral spirits;
• driers (lead, manganese, calcium).

There is a separate group of materials called synthetic varnish.They are by-products of petrochemical plants, which tend to form a film when dry.The quality of these materials is low, and they are used for not too demanding applications.Due to the poor quality in the home, they are not widespread.In this regard, to make such a mixture in the home does not make sense, and the process is too complicated.

Note! Using synthetic varnish, you must strictly follow the instructions of the manufacturer, as it has a limited scope.

The diluted varnish and whether to do it?

As linseed oil is to freeze the property, it is often necessary to dilute it.However, many experts argue that it is meaningless.This is due to the fact that the material, which has already entered the stage of polymerization by oxygen oxidation, will not have their original qualities.Drying should itself be fluid and oxidize only applied surface.But many domestic craftsmen think differently and bred them for later use.

Before diluted mixture should be familiar with the composition.Since they are natural, synthetic and semi-natural, and it is necessary to breed them in different ways.Natural and semi-natural blend is best diluted with mineral spirits or turpentine, but synthetic - solvent.In any case, better to start to dilute a small amount of linseed oil and trace her reaction.

Important!mixture is not recommended to dilute gasoline and kerosene.

Dilute silverfish

often linseed oil used to dilute the silverfish.This aluminum powder, which is produced by grinding.It perfectly fits and protects the surface.Consider how silverfish diluted varnish.For dilution use materials in a ratio of 1: 4 or 1: 3, that is, per liter of linseed oil should fall 250-350 grams of silverfish.To obtain a homogeneous mass in the first container is filled with jewel, and only then gradually poured diluent.All work should be carried out under vigorous stirring of the mixture.

Important!Can not be used for razbavki natural varnish as part of their coating properties deteriorate.

also often raises the question of how different materials are applied in a sequence.So, lacquer varnish can be put to better protect the surface.If serious protection of the surface is not necessary, it is possible to paint it did not open.Conversely, if you want to protect the painted surface, it is possible to cover it with varnish.
