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 a square meter of surface with it, it is easy to make calculations regarding the required number of cans in a particular case. It is convenient, first of all, in terms of cost savings. After all, paint has its own expiration date. And the remaining banks may never come in handy. Thus, paint consumption per 1m2 is a very important parameter.
How to do the calculations
First of all, you need to measure the surface to be processed along the perimeter and calculate the area. This will make it easy to determine exactly how many cans you need to purchase. At the moment, the paint is most often sold in 3-liter containers. Thus, for example, for painting a floor with an area of 30 m22 at the specified consumptionin 0.05l/1m2 you will need to purchase 2 cans. But this is only if the surface has previously been painted or well primed. Sometimes the labels also indicate another parameter - how many meters one liter is enough. In this case, it will be even easier to calculate the number of cans.
Dependence of consumption on the type of dye
Of course, it takes a different number of different types of helmets to paint a square meter of surface. Let us consider this issue in more detail, since it can be quite important when performing repair work. So, for painting ceilings, water-dispersion acrylic paint is usually used. For the treatment of wooden and metal surfaces - various types of enamel. 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 consumption of paint per 1m2 when using one or another of its varieties?
Acrylic water dispersion paint
Such dyes can be used both for fine finishing of walls and ceilings indoors, and for facade decoration. After application, they form a durable matte film that perfectly hides all minor defects in the treated surface. You cannot use the same type of acrylic water-based paint for both walls and ceilings.
The purpose of the composition must be indicated on the label. CaseThe fact is that on the walls the dye is subjected to much more significant loads than on the ceiling. Acrylic paint consumption per 1m2 is usually 1/8-1/6 liter. That is, for staining 6-8 m2 you will need 1 liter of this product.
Tikkurila Paint
Tikkurila brand dyes enjoy well-deserved popularity in our time. They form an unusually strong film on the treated surfaces, resistant to abrasion and cracking.
Dyes are produced 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 1m2 ("Tikkurila") is 0.1-1/8 liters. That is, for coloring 8-10 m2 you will need to purchase a liter jar. When treating outdoor surfaces, a liter of product takes about 10-14 m2.
PF Paint
Pentaphthalic enamel is another fairly popular dye today. It is used for surface treatment both indoors and outdoors.
In the event that it is applied to a previously unpainted surface, the consumption will be about 180-200 gr. material per 1m2. This is very little. If the surface is treated, already painted, or a second layer is applied, the consumption of PF paint per 1m2 will decrease by about 40 gr.
When buying any dye, including pentaphthalic enamel, you shouldkeep in mind that usually at least two layers must be applied to obtain a high-quality finish. Therefore, when painting a new, never before treated surface, you will have to purchase a product at the rate of approximately 320-350 gr. 1m2.
Powder paint
Powder polymer paints are becoming more and more popular lately. 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. The films created by such dyes can withstand truly colossal loads. So, what is the paint consumption rate per 1m2 in the case of using a powder composition?
The calculation is made based primarily on the weight of the agent 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 using a spray gun for painting, it takes about 120-140 gr. funds.
Factors affecting paint consumption
Consumption of paint per 1m2 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 indicating 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 processedthe wall, for example, absorbs the product very strongly. 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 metal and plastic surfaces, the product will, of course, be less.
Thus, the consumption of paint per 1m2 depends primarily on the variety of the composition itself, as well as the type of surface being treated. In addition, this indicator is largely influenced by which tools will be used in the process of performing the work. So, when painting with a brush or paint roller, a little more is consumed than when using a spray gun. Much in this regard also depends on the skill of the person doing this work.
