Paint consumption per 1 sq. m of wall area: we calculate according to the selected material

Today, painting has become the most common way to decorate walls. Almost every home owner can transform the interior of his apartment with his own hand using only paint. The final cost of the work will depend on how competently the calculation of the required dye is made, and it will be possible to avoid buying an excess amount of paint.

Before you start counting the amount of paint that will be required during the finishing of one room or an entire apartment, you need to study all the factors that affect the consumption of such a composition. Usually, the consumption of the coloring agent is calculated per 1 m2 of the surface.

It seems to many that the calculation is very simple: you need to measure the surface area of ​​the walls and ceiling that need processing, and, having studied the instructions offered on the product packaging, you can get to work. But this is along the ideal "trajectory", that is, when the area is absolutely smooth.

In fact, many factors affect the amount of paint consumed:

• the way by which the paintwork is applied;
• Colour;
• type of composition;
• the type of surface to be treated.

It is necessary to take into account all the above aspects in order to correctly calculate how much mixture is required.

The fluidity of the paint and its type are the main factors that influence the count. This indicator is called "hiding power" and differs in all types of mixture.

Acrylic paint is a water-dispersion mixture based on acrylic. In tinting, special colored pastes are used, which are also created on the basis of this raw material. The surface to be painted will have a matte color.

Compositions of this type are widely used in both indoor and outdoor repair work. One of the main advantages of the acrylic composition is that it is resistant to ultraviolet radiation, therefore it adheres so well to the facade walls and does not lose its color in the sun. The decorative qualities are preserved for 5 years.

1 liter per 8 square meters - this is the consumption of acrylic mixture when painting the surface of the walls. Here the calculation is for one layer. However, this indicator may differ for paints from different manufacturers.

The amount of product that you need during work depends on the quality of the product. Walls with acrylic paint are covered with at least two layers, preferably three.

It is advisable to pre-coat the walls with a primer, as this will significantly reduce material consumption.

The proportion should be 50/50. The ceilings are covered with matte latex paint.

This variety is not resistant to dampness, since it is based on an aqueous solution. In order to give it water-repellent properties, they use various additives.

Firstly, its consumption per 1 square meter will depend on the thickness of the water-based paint. m. If the mixture is too thick, then it must be diluted with water. The emulsion must be applied in a thin layer. After the first layer has completely dried, you need to go through the paint one more time.

Counting of water-based paints is made from the standards of 1 liter per 10 m2 of the painted area.But in reality, this indicator can vary from 1 liter per 6 m2 to 1 liter per 18 m2, so it becomes much more difficult to make an accurate calculation. Everything will depend on side factors: the structure of the area, density and color.

Oil paint. During the production of such compositions, drying oil is often used. It acts as a solvent. After such a composition is applied to the surface, it begins to polymerize in the fresh air.

PF-115 enamel is the most common composition of oil paints, it can create a film of increased strength. This film has a uniform texture. If you paint the wall in one layer, then the approximate paint consumption will be 120-130 gr. per 1 m2.

When calculating the quantity, you need to know that the consumption of oil paint will depend on the color. The hiding power of pigments is greatly influenced by the density of the mixture used.

Below are examples of indicators of mixture consumption per 1 kg:

• black color - up to 20 m2;
• blue color - up to 17 m2;
• blue color - up to 15 m2;
• green color - 13 m2;
• white color - up to 10 m2;
• yellow color - up to 10 m2.

According to the above data, you can see: the lighter the color, the smaller the surface can be covered with it.

Below is a list of the best manufacturers of paints and varnishes:

• Dufa superweiss - differs in durability and color purity. The paint is used in small rooms, it allows you to visually increase the volume of space.
• Caparol CapaSilan - the manufacturer focuses on silicone ceiling coverings. The paint has the ability to cover small cracks up to 2 mm.
• Dulux - the best option when painting ceilings. Country of origin - Great Britain.
• "Halo Discount" - ceiling paint that dries 1.5 - 2 times faster than paints from other manufacturers.

• Tikkurila Euro 7 - a very expensive option with excellent product quality. The paint is UV resistant.
• Ceresit CT 54 - paints and varnishes for facade works. The product is endowed with anti-fungal properties.
• SNIEZKA EKO - suitable for use on any type of surface. However, the flow rate is quite large, which is a significant disadvantage.
• "Expert" - paint from the manufacturer DEKART. The only drawback of the product is excessive thickness. This can be solved, but the problem is not indicated in the instructions on the package.
• "Tex pro" - a fairly budgetary paint option, characterized by the absence of a pungent odor.

The calculation of paint consumption also depends on the type and texture of the surface intended for painting. The consumption indicator can increase significantly if the paint is applied to plaster or concrete, and a smooth, dense surface, for example, sheet steel or galvanized steel, significantly reduces this indicator.

Today, people resort to a variety of methods to reduce the porosity of a surface. Wood structures are pre-sanded and covered with several layers of drying oil, the base is covered with a primer-composition.

Primers are designed to fill small pores and small cracks in the surface to be painted. This reduces the level of absorbency of the paintwork, thereby avoiding unnecessary painting costs.

The way in which the paint is applied also has an impact on how much material will have to be used.

True, the use of a spray gun is not always suitable.

Having studied the above information, almost everyone will be able to correctly calculate how much composition he needs, even without the special skills of a plasterer-painter. Of course, there are many aspects that affect this indicator, so even professionals cannot make an accurate calculation, however, the approximate consumption of the mixture can always be calculated.
