Repair work is impossible without the correct calculation of the consumption of materials. It is especially important to correctly calculate the amount of paint, which will significantly save not only financial resources, but also time.
Acrylic paints are some of the best on the market, but they cost a lot of money. If you buy too much of a substance, there will be excess, but the lack threatens not only to interrupt the work process, but also to break the identity of the shades on the painted surface.
Let's consider how to correctly calculate the amount of paint required for repair work.
What can affect paint consumption?
Often on paint cans they write how much volume is enough for a certain area. Only blindly using such numbers is not worth it, because all averaged calculations are based on the fact that the walls in the house are perfectly even. In real life, much more paint is needed than is stated in the instruction sheet on the container.
The main factors that affect paint consumption:
- method and methods of applying paint to walls or facades;
- what color was chosen;
- wall texture;
- what type of paint will be used.
Possible methods and means of application
A variety of tools are used to apply acrylic paint. Using a roller with a medium pile of flat relief, you can create a flat relief, and if you want to achieve the effect of a stone wall, it is better to use a short-haired roller… The specifics of rolling in both cases follows the same principle.
If we talk about a spray gun, the result of the work will depend on what kind of tool is chosen, what kind of mechanical pressure will be used during operation.
A wide brush is best used to scuff the wall. Use hard sponges or plastic trowels to blend.
Standard flow calculations
On average, if we are talking about acrylic paint (for facade or for interior work), then one square meter takes from 170 to 210 grams. You also need to take into account the factor that for acrylic paint all calculations are made in grams, not milliliters.
It is important to know that average rates are only suitable for perfectly smooth surfaces.
To correctly calculate the number of square meters for painting, calculate:
- distance between floor and ceiling;
- the length of each of the walls of the room;
- multiply the length by the width.
Quite often premises are of a complex configuration, so it is important to take into account the complexity of the "relief". It is imperative that during the calculations, you should be guided by the plan diagram.
You will learn more about paint consumption per 1m² in the following video.
Calculation of the amount of acrylic paint for wallpaper
Acrylic wallpaper paint has the following benefits:
- does not release toxins;
- has a good adhesion coefficient;
- dries quickly;
- is inexpensive;
- resistant to moisture and temperature.
If you need to apply acrylic paints for non-woven wallpaper, the standard consumption will be 210-260 grams per 1 m². In order to make painting as economical as possible, the main thing is to choose the right roller. If paint is applied in 2 layers, costs will be, respectively, 400-450 grams one square meter.
Not only the material consumption, but also the layer structure will depend on which roller is purchased..
If we are talking about painting wallpaper with an absolutely flat surface, then to save money, a roller with a pile of at least five millimeters is chosen. More material is used to cover textured surfaces; for painting such planes, a roller is needed with a pile length of at least 25 mm.
Here you should know when to stop, because too long a pile will absorb a lot of substance, and it will be distributed unevenly.
We calculate the consumption of dye for painting the facade
There are options when you can significantly save paint without compromising the quality of the coating. The consumption of the substance will depend on the tool that will have to be used, as well as on the material from which the facade is made and its texture.
At the standard rate, about two hundred grams of paints and varnishes are spent on painting the facade per one square meter of the coloring matter. If staining is performed on decorative plaster, paint consumption increases by at least fifty milliliters for each square meter.
When using textured acrylic paint, you should prepare 40 percent more of the coloring material.
