Liquid wallpaper: calculate the consumption per 1 sq.

Indoor wall decoration is a trivial task that can be solved in various ways. The main criterion on which the quality of surface decoration depends is the material. Today, paper and fabric canvases have gained immense popularity. Among this variety, modern liquid wallpaper can be distinguished.

Liquid wallpaper is a type of plaster applied to walls for the purpose of decorating them. This product is presented in the form of a mixture that evenly covers the base.

The composition of this substance includes several main components:

• cellulose in the form of flakes;
• natural cotton;
• silk fiber;
• foil and special glue.

Ideally, manufacturers expect that the wallpaper will be applied to even walls without cracks, depressions, irregularities and other defects. If all these nuances are present, then the number of flakes will increase by an undefined value.

How to properly apply liquid wallpaper to the wall can be seen in the following video.

As for the technology of applying these materials, it is worth noting that you can cover the walls with liquid wallpaper with a spatula or a special pistol. The first option is more labor-intensive and unpredictable, since it makes it difficult to control the uniform alignment of the layer manually. If you use specialized sprayers, then the material will surely lie in an even layer. It should be noted that this method reduces the consumption itself by about 30-50%, depending on the surface quality and other factors.

Calculation of the required volume of material per 1 sq. M is an important step in order to purchase the required amount. The consumption of liquid wallpaper is not constant and depends on several features:

• Homogeneity of the solution. Wallpaper is prepared by mixing the components with water. With the wrong approach, you can get a composition, the density of which can vary significantly. With inaccurate application, the mixture will be unevenly distributed, which will affect the fill factor per square meter;

• The amount of liquid. Water is the main component of the wallpaper, without which the mixture will not be applied to the wall. It is also important here to observe the correct ratio of liquid and flakes, since the plasticity of the product depends on this. If the substance is too thick or liquid, then it will not be possible to evenly distribute it over the surface;
• Time after cooking. If you use the mixture only after a few days, then it will already lose its plasticity. Also, this fact will negatively affect the consumption of material. It will be very difficult to calculate the number of such a composition.

One of the ways to find out the number of wallpapers is to calculate their volume depending on the unit of area.

To calculate the consumption of plaster per 1 sq. M, you need to perform a few simple operations.

1. First of all, you should find the flow rate, which is indicated by the manufacturer. This value is often printed on the packaging itself. It can be indicated in relation to weight or unit of area;
2. When you know the flow rate, you should increase the resulting value by about 10%. A similar algorithm allows you to approximately find out the real amount of the mixture that will cover a square meter.

If the consumption is not indicated on the package, then it can be calculated based on the weight of the product. Often 200-350 g of dry mix is ​​enough for a square meter of a wall. But this is taking into account the fact that the material will be applied evenly and in a layer with a thickness of 1.5-2 mm. Based on these data, it can be said that one 5 kg bag is enough for about 15-20 square meters.

Consumption calculations are carried out in order to find out how much material will have to be spent on a specific wall or room.

To calculate this indicator, you can use the following algorithm of actions.

• Initially, you should find out the overall dimensions of the room or a particular wall. To do this, measure their length, width and height;
• After that, based on these indicators, the area of ​​each individual base is calculated. As a result, all received data should be summarized;
• At this stage, you need to calculate the area of ​​windows, doors and other elements that will not be covered with plaster. The calculation algorithm is the same and involves multiplying the width by the height;

• To get the real area of ​​the room, you need to subtract the size of the unused surfaces from the total value. When the dimensions of the room are calculated, you can find out the volume of the mixture. To do this, the area is simply multiplied by the flow rate, and then the resulting value increases by about 10-15%. Please note that the stock should be taken without fail, since you will not be able to calculate the specific volume of the solution to the nearest gram.

A similar algorithm can be used for cases when each of the walls is covered with a different type of mixture. If several color shades are used that are needed to form patterns, then it is advisable to take into account the area of ​​these elements when calculating.

The consumption indicated by the manufacturer is not always a real value and can be drastically different when the substance is applied to the wall. Therefore, in order to find out this indicator more accurately, you can calculate it yourself.

This process is quite simple and involves performing such sequential operations.

• Initially, you need to find a flat wall on which you can apply wallpaper. To do this, mark 3 pieces of the same area on its surface. To better calculate, you can use elements of 1 sq. M.
• After that, the mixture is prepared according to the manufacturer's instructions. To do this, weigh about 300 g of flakes and add the right amount of water there - soak. The resulting solution is weighed in order to further calculate the flow rate.

• Then, plaster is applied to one of the pieces of the wall with a spatula. When the surface is completely covered, the remaining mixture is weighed again and the amount of mortar used for the plaster is obtained.
• To find out the consumption, the weight of the material should be divided by the area that it covered. It is important to bring the values ​​to square meters, since in such units it is best to calculate the flow rate.

After that, a similar procedure is carried out on the remaining two sections of the wall. All the values ​​obtained should be calculated and divided by 3. Thus, you will find out the average, which will indicate the real consumption of wallpaper.

Applying liquid wallpaper is a complex procedure that requires certain skills and experience.

But there are ways to reduce consumption:

• Application of the solution with special sprayers. They distribute the composition more evenly over the surface, while minimizing physical effort;
• Aligning the walls. The smoother the base, the thinner the layer needs to be applied to it.Therefore, it is important to level the walls with plaster and several types of fillers;
• Surface treatment with special primers. Experts recommend using deep penetration mixtures that reduce the absorption of wallpaper material by the wall;
• Filling with snow-white solutions. This is necessary in almost any case, since the wall is visible through the liquid wallpaper, and it should be of a neutral color.

The choice and calculation of liquid wallpaper involves the implementation of many rather complex operations that are better to be trusted by specialists. They (based on their experience) will calculate the correct amount of material with a minimum amount of residue after completion of the work.
