Drying and its use in the treatment of various surfaces

Types varnish

Of all the types of the most popular natural, combined, oxoil.Also alkyd compositions and composites may be used.Describe in detail each of them.

• Natural linseed oil is made up of this oil has the form of a thick, opaque fluid (black and brown).Manufactured in accordance with GOST 7931-76.Used for impregnating wood substrates and pastes diluting paints.Professional staff recommend it to be used only indoors.Outside - it is quite impractical.
• Oksol made of oil and solvent, in accordance with GOST 190-78.Moreover, the oil content is about 55%, the remaining 45% - solvent (white spirit and drier).The mixture has a bit of an unpleasant odor that may persist after drying layer.Oksol much cheaper than natural drying oil.Used to plaster wooden bases inside buildings.Outside it can also be used, but is required to be applied on top of varnish, paint or enamel.
• Combined , in essence, no different from the previous structure, a ratio of solvent and oil.The oil content of the mixture is about 70% and 30% mineral spirits.The scope of use is the same as that of the oksolem (for wooden and plastered walls).
• composite consists of synthetic substitutes, and not from natural oils.Most often it contains petroleum products.It made this linseed oil according to the specifications defined by GOST on it there.Unlike natural, these compounds are virtually colorless and longer dry form.They are used only for outdoor use, as they have some toxicity.
• Alkyd made of alkyd resin modified with the addition of oil and solvent.These compositions are much more economical to use than natural drying oils, because they can easily be used for the exterior as well as for the preparation of paints.

Recommendations for choosing

Before buying varnish should explore the contents of the jars carefully.First of all, note the color, it should be dark brown (in-kind) and colorless (in composition).Plus, learn the composition indicated on the label, as well as compliance with GOST (available at oxoil and natural varnish).

On oxoil and natural drying oil must also present a certificate of conformity for the composite - hygienic.And indeed, with the latter, be very careful, because it has toxicity, it is important that there was no fuzz (residue oils), or it never dries.

also necessary that the composition was not osprey (substances from the refinery).With the content of linseed oil is also unlikely to dry up.And finally, it may be noted that - look at the fluid homogeneity.There must be no residue, mechanical impurities, and, of course, the smell.

Drying: use

As mentioned above, the main purpose of this mixture - in the surface treatment, it is also used for the manufacture of paints.If we talk about the processing bases, the ideal linseed oil for wood.She was impregnated with the product as well as the walls.However, for exterior varnish is better to use only as a surface preparation for subsequent painting.

And use it is recommended oxoil or alkyd compositions (not natural, which do not practical).This is due to the fact that resistance to precipitation and durability of the coating mixture natural minimal.It is better to use it for dilution of paints.If we talk about the inner workings, then natural drying oil is well suited, since it has an ecological structure and has no smell.

all kinds of drying oils used in the manufacture of paints.For example, natural use for gustotёrtyh paint, alkyd - for oil.Only the composite is not applicable because of their poor quality.
