Calculation of paint consumption is usually performed per square meter of surface. When buying, you should definitely pay attention to this indicator, usually put on the label. Knowing the amount of paint needed to cover a square meter of the surface, it is easy to make calculations regarding the required number of cans in a particular 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 may never come in handy. Thus, the paint consumption per 1m2 is a very important parameter.
How to make 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 exactly how many cans you need to purchase. Currently, paint is most often sold in 3-liter containers. Thus, for example, for painting a floor with an area of 30 m
2 at a specified flow rate of 0.05 l / 1 m
2 you will need to purchase 2 cans. But this is only if the surface has previously been painted or well primed. Sometimes another parameter is indicated on the labels - how many meters is enough for one liter. In this case, calculating the number of cans will be even easier.
The dependence of the flow on the type of dye
Of course, it takes a different number of different types of helmets to paint a square meter of the surface. We will consider this issue in more detail, since it can be quite significant when performing repair work. So, water-dispersed acrylic paint is usually used for painting ceilings. For processing wooden and metal surfaces - all kinds of enamels. Facades are painted using special compositions that are resistant to water and temperature extremes.
Powder products are considered very effective and easy to apply
. So, what is the paint consumption per 1m2 when using one or another of its varieties?
Acrylic water dispersion paint
Such dyes can be used both for the finishing of walls and ceilings indoors, and for the design of facades. After application, they form a strong matte film that perfectly conceals all minor defects of the treated surface. It is impossible to use the same type of acrylic water dispersion paint for walls and ceilings.
The purpose of the composition must be indicated on the label. The fact is that on the walls the dye is subjected to much more significant loads than on the ceiling. The consumption of
acrylic paint per 1m2 is usually 1 / 8-1 / 6 liters. That is, for staining 6-8 m
2 you will need 1 liter of such a tool.
Tikkurila paint
Dyes of the Tikkurila brand enjoy quite well-deserved popularity in our time. They form on the processed surfaces an unusually strong film resistant to abrasion and cracking.
Dyes are available for painting plastered surfaces both in dry rooms (in this case, compositions based on acrylic copolymer or latex 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 you will need to purchase a liter jar. When treating surfaces outdoors, a liter of product leaves about 10-14 m 2 .
PF paint
Pentaphthalic enamel is another dye that is quite popular today. It is used for surface treatment both indoors and outdoors.
In the event that it is applied to a previously unpainted surface, the flow rate will be about 180-200 g. material per 1m
2 . This is very little. If the surface is already painted, or a second coat is applied, the PF paint consumption per 1m2 will decrease by about 40 gr.
When buying any dye, including pentaphthalic enamel, it should be borne in mind that usually at least two layers must be applied to obtain a high-quality finish. Therefore, when painting a new, never before processed surface, you will have to purchase a tool at the rate of about 320-350 gr. on 1m 2 .
Powder paint
Powder polymer paints have recently become increasingly popular. And no wonder. After all, with their help, you can get a finish with properties that are completely impossible to achieve using conventional liquid formulations. Films created by such dyes can withstand truly colossal loads. So, what is the rate of paint consumption per 1 m2 in case of using a powder composition?
The calculation is made in this case, based primarily on the weight of the product and the thickness of the applied layer. The "lighter" the paint, the less it is needed to obtain a high-quality coating. The thickness of the protective and decorative layer should be at least 100 microns. As practice shows, when used for painting a spray gun, about 120-140 grams are left per 1 m
2 of surface in this case. facilities.
Factors Affecting Paint Consumption
The consumption of paint per 1 m2 depends not only on its properties, but also on which surface it will be applied to. This factor often becomes decisive in the calculation. When specifying certain consumption rates on the label, the manufacturer usually implies that the paint will be applied to a not too porous surface. In practice, it often happens that the processed wall, for example, absorbs the agent very strongly. As a result, it leaves a little more. Usually in such cases you have to paint the surface in several layers. This applies, for example, to materials such as wood and concrete. When painting metal and plastic surfaces, of course, less will be required.
Thus, the consumption of paint per 1 m2 depends, first of all, on the variety of the composition itself, as well as the type of surface to be treated. In addition, this indicator is largely influenced by what kind of tools will be used in the process of performing work. So, when painting with a brush or roller, a little more is consumed than when using a spray gun. A lot in this regard also depends on the skill of the person performing this work.
