Consumption of paint on (1m2). What is the rate of paint consumption per (1m2)

Calculation of paint consumption is usually performed per square meter of surface. When buying, be sure to pay attention to this indicator, usually affixed to the label. Knowing the amount of paint needed to cover the square meter of the surface, it is not difficult to calculate the required number of cans in this or that case. This is convenient, first of all, in terms of cost savings. After all, the paint has its own expiration date. And the remaining banks, perhaps, will never be useful. Thus, the paint consumption per 1m2 is a very important parameter.

How to perform calculations

First of all, you need to measure the surface that will be processed, along the perimeter and calculate the area. This will make it easy to determine how many cans you need to purchase. At the moment, the paint is most often sold in 3-liter containers. Thus, for example, to paint a floor with an area of 30 m ² at the indicated consumption of 0.05 l / 1 m ^2, you will need to buy 2 cans. But this is only if the surface was previously painted or well primed. Sometimes on labels another parameter is specified - on how many meters one liter suffices. In this case, it will be even easier to calculate the number of cans.

Dependence of consumption on the type of dye

Of course, the coloring of a square meter of surface takes a different number of different types of helmets. Let's consider this issue in more detail, since it can be of great importance when performing repair work. So, for painting ceilings water-dispersive acrylic paint is usually used. For the treatment of wood and metal surfaces - various kinds of enamels. Facades are painted using special formulations resistant to water and temperature changes. Very effective and convenient in the application are powdered products. So, what is the consumption of paint per 1 m2 when using one or another of its varieties?

Acrylic waterborne paint

Such dyes can be used both for finishing the walls and ceilings indoors, and for decorating the facades. After application, they form a strong matte film, perfectly concealing all minor defects of the treated surface. Use the same type of acrylic waterborne paint for both walls and ceilings.

The composition is always indicated on the label. The fact is that on the walls the dye is exposed to much more significant loads than on the ceiling. The consumption of acrylic paint per 1 m2 is usually 1 / 8-1 / 6 liters. That is, for staining 6-8 m ^{2 you} will need 1 l of such a remedy.

Paint "Tikkurila"

Dyes of the brand "Tikkurila" are in our time quite well-deserved popularity. They form an unusually strong film on the surfaces to be treated, resistant to abrasion and cracking.

Dyes are produced, intended for painting plastered surfaces both in dry rooms (in this case acrylic copolymer or latex formulations are usually used) and outdoors (alkyd enamels). In the first case, the paint consumption per 1 m2 ("Tikkurila") is 0.1-1 / 8 liters. That is, for coloring 8-10 m ² will need to buy a liter jar. When treating surfaces outside the room, a liter of the product leaves approximately 10-14 m ² .

PF paint

Pentafthal enamel is another popular dye for today. It is used for surface treatment both indoors and outdoors.

In the event that it is applied to an unpainted surface, the consumption will be on the order of 180-200 g. Material on 1m ² . This is very little. If the surface is already painted, or the second layer is applied, the consumption of PF paint per 1 m2 will decrease by approximately 40 g.

When buying any dye, including pentaphthalic enamel, it should be borne in mind that usually to obtain a high-quality finish you need to apply at least two layers. Therefore, when painting a new, never previously treated surface, you will have to purchase a tool at a rate of approximately 320-350 grams. On 1m ² .

Powder paint

Powder polymer paints are becoming more popular recently. And no wonder. After all, with their help you can get a finish with such properties that it is absolutely impossible to achieve, using the usual liquid formulations. Films created by such dyes can withstand truly colossal loads. So, what is the norm of paint consumption per 1m2 in case of using powder composition?

The calculation is made here, first of all, based on the weight of the agent and the thickness of the applied layer. The "lighter" the paint, the less it is needed to get a high-quality coating. The thickness of the protective and decorative layer should be at least 100 microns. As practice shows, when using a sprayer for painting, 1 to 2 m ^of surface in this case takes approximately 120-140 grams. facilities.

Factors affecting the consumption of paint

The paint consumption per 1 m2 depends not only on its properties, but also on what surface it will be applied to. This factor often becomes decisive in the calculation. Pointing to the label of these or other norms of consumption, the manufacturer usually means that the paint will be applied to a not very porous surface. In practice, it often happens that the treated wall, for example, absorbs the agent very much. As a result, it takes a little more. Usually in such cases it is necessary to paint the surface in several layers. This applies, for example, to materials such as wood and concrete. When painting the same metal and plastic surfaces, the funds will go, of course, less.

Thus, the paint consumption per 1 m2 depends, first of all, on the variety of the composition itself, as well as the type of the surface to be treated. In addition, this indicator is significantly influenced by which tools will be used in the course of work. So, when painting with a brush or a paint roller, a little more is consumed than with a spray gun. Much in this respect depends on the skill of the person who performs this work.
