The main purpose of the primer
For an ideal end result of repair work inside the premises for various purposes, whether it is painting or using roll wallpaper, the wall surface is covered with a primer. This is necessary so that the plaster does not fall off and crack over time, and the wallpaper does not go in whole stripes.
The primer, thanks to its good technical characteristics, contributes to better adhesion of the putty and the finishing material, helping the wall to maintain the original beauty acquired after repair.
For the result of your work to be magnificent, never forget about such an important moment as priming. But what tool to choose for this? Shops of building and decoration materials offer so many options that it is not a sin to be confused by an ordinary person. Let's look into this further.
to contents ↑What is an oil based primer?
An oil alkyd compound is called an oil based primer, which contains synthetic synthetic oil resins. In addition, it contains drying oil and grated paint. These components determine the future color tone of the product.
An important component of the oil primer is the solvent, but it is present only in the spray. If the product is sold in cans and should be applied to the surface with a brush or roller, then there will be no solvent in it.
Note that it is worth buying only products with a quality certificate. So you can protect yourself from the risk of buying a fake or low-quality product.
Brief description of oil soil
An oil based primer often has a matte finish. From a design point of view, it is a universal product, since it can be tinted.
The average material consumption is 50 - 100 g. per 1 sq.m., however, this parameter is determined by the scope and absorbent properties of the surface to be coated.
The oil primer layer has a coating thickness of up to 1 mm. It is possible to achieve complete drying of the first layer of the agent only after one day. Only after this time can we proceed to the application of the second layer.Before using it, manufacturers recommend carefully placing the composition.

These funds have a number of positive qualities:
- great for preparing the surface for painting with oil paint;
- provide wood with high resistance to moisture;
- perform the function of a natural surface antiseptic;

Types of oil soil
Today you can buy two types of acrylic oil-based primers. What type of primer is it intended for? We will answer this question further:
- Universal, due to its excellent technical characteristics, it is perfect for covering surfaces made of brick or concrete, but it is completely unsuitable for wood and metal. It is these materials that are ideal for self-processing of walls before they are painted or glued with wallpaper;
- Primer paint is intended for the treatment of metal or wooden surfaces. It has a standard set of characteristics for soil, but in addition it is also characterized by antifungal properties. Often it is white, therefore, after priming with such a tool, the surface appears painted.
Features of the use of oil soil
When performing priming work, it is important to remember the following rule: the product must match the composition of the paint used. In other words, alkyd enamel will lie perfectly on alkyd soil, and oil enamel on oil. Otherwise, there will be problems with the wall coating in the form of cracks and partial chips.
Oil primer
To do the work yourself, you will need to buy a universal type oil primer with a quality certificate and a special tool:
- a cuvette with a ribbed squeezing place into which soil is poured;
- roller and brush, which process hard-to-reach corners;
- telescopic handle if you do not have a stepladder.
Phased work involves the following operations:
- pour the finished soil into the cuvette;
- put the roller on the telescopic tube and soak it in the tool. Then, with a few movements along the ribbed surface, remove the excess primer from the roller;
- apply the product on the wall.
Note that it is allowed to apply several layers of primer. It is important to observe the current time for drying. So the second layer of the agent should be applied only when you are convinced of the complete drying of the first layer. According to manufacturers instructions, this may take about 5-6 hours. But depending on external factors, this indicator may vary. That's all. In fact, nothing complicated.
