Oil paint for walls, ceilings and other surfaces was used in Soviet times in every house and apartment. The choice of finishing materials was small, and such paint was always widely available on store shelves, and the price for this material was acceptable.
Today, in any building market, when choosing coloring agents, you can get lost in a variety of options, but the good old oil paint is still in demand and reliably holds its position on the shelves.
What is this material?
The binder in the composition is linseed oil. Now this substance just like in acrylics guts.pk/shop/category/art-supplies/acrylics/ is produced mainly by a synthetic method, since it is unprofitable to use natural oils due to their high cost. Mineral flour and other additives act as fillers, while inorganic pigments give the solution a certain color. The solvent allows you to achieve the desired consistency and degree of viscosity.
Features of oil-based paint
Before deciding whether to purchase this material for the upcoming repair work, it would be good to familiarize yourself in detail with the advantages and disadvantages of such a choice.
pros
The versatility of oil paint has long been known. This composition lies on any surface and holds on to it with a stranglehold. Wood, concrete, plaster, plastic, brick, glass - all these bases can be successfully painted with this product.
The following advantages of this material can be noted:
has high anti-corrosion properties, therefore, it is with oil paint that metal structures are often treated;
the coating forms a hard film resistant to mechanical stress;
the surface painted with oil paint becomes water-repellent, easy to clean and is not afraid of exposure to household cleaning agents;
the coloring composition applied to a properly prepared base will last for many years, reliably protecting the surface from damage;
working with oil paint is not difficult, no serious professional skills are required for this;
the product has good hiding power, that is, it qualitatively overlaps the original color of the painted surface;
the material can be used not only for interior decoration, it is successfully used for facade work, as well as for painting almost any objects in the open air (roofs, benches, gazebos, fences, etc.).
Outbuildings inside and outside, utility and industrial premises are covered with oil paint. Modern decoration of stairwells in the entrances is often still carried out using the same coloring agents.
Oil-based materials are used to refurbish the exterior of country houses or cottages, paint plank floors, walls and ceilings.
Unfortunately, the formulations also have a number of disadvantages that can serve as a reason for refusing to purchase and use them.
Minuses
First of all, I would like to dispel the myth that there are odorless oil paints. A characteristic sharp and rather unpleasant "chemical" aroma, which does not disappear for a long time, will be present in one way or another when working with this material.
Modern manufacturers find ways to muffle it a little, but so far no one has been able to completely neutralize it. Accordingly, if you are looking for an odorless coloring agent, then oil solutions are not your option.
The disadvantages of this type of paint and varnish products are the following:
the composition of the oil paint contains toxic substances that actively evaporate when the fresh layer of the coating dries and can cause serious poisoning; it is recommended to work with this coloring agent in a respirator and goggles;
even after the coating dries, a small amount of a harmful substance will be released into the air, and this can provoke an allergic reaction in people with hypersensitivity;
the vapor permeability of the coating is practically zero, which can negatively affect the quality of the finish during sharp temperature fluctuations (cracks and bubbles appear on the surface);
drying oil, on the basis of which the coloring material is made, has an unpleasant property to turn yellow over time, which is why the color of the painted surface changes noticeably and fades.
Despite the listed disadvantages of oil paints, practice again and again confirms the appropriateness of their use. These formulations have very good technical characteristics, and the extremely affordable price is still one of the most important factors when choosing them.
Application
One of the options for interior decoration of the premises is painting the walls with oil paint. It is practical, inexpensive and simple. This is especially true for surfaces already painted with this composition, since the preparatory process will be greatly simplified:
a similar solution will lay on oil paint perfectly if there are no cracks and other defects on the surface; adhesion will be at the highest level;
you will avoid the tedious and time-consuming process of removing old paint, which sometimes also costs a pretty penny.
Where to begin?
They always start by clearing the walls. They are washed if the problem is only in the accumulated dirt. They are cleaned with a spatula, a scraper, a drill with special attachments, a construction hair dryer or chemical compounds designed to remove old paint (washes) if the coating is in a deplorable state. In the same case, leveling of the surface is also required. At this stage, putty starting and finishing mixtures, sandpaper are used.
A smooth and smooth wall is completely cleaned of dust (you can use a household vacuum cleaner) and primed.
The need for a primer is as follows:
The consumption of the coloring material is reduced.
The adhesion of the paint to the surface is improved.
Primer mixes often contain antiseptics, which is very important when decorating rooms with high humidity levels; this way you can protect the premises from the appearance of mold and other harmful microorganisms.
The simplest tools will do:
paint brushes guts.pk/shop/category/art-supplies/brushes/ and roller,
ditch for paint,
adhesive masking tape.
If you have a spray gun, you can use it. In any case, the joints with the ceiling, door frames, baseboards, sockets and switches are first pasted over with masking tape. Now you can paint.
