The consumption of tile adhesive per 1 m2, the rate of consumption of tile adhesive from manufacturers

The use of tile is one of the most common ways of finishing a bathroom and a bathroom. For repair, in addition to the tile itself, consumables are required, and the main one is tile glue.

One of the first questions arising when buying materials used for work for tiles - is how large is the consumption of tile adhesive per 1 m2.
Since on the basis of this quantity it is possible to calculate not only the volume of the desired material, but also its cost. Unequivocally answer this question, in principle, it is impossible, but to calculate the approximate solution consumption per 1 m2 is quite realistic.

How can I calculate the required amount of the mixture?

The first option that comes to mind is to find out about the required quantity of the person who produces it. For a specific manufacturer, there are norms for the consumption of tile adhesive from the condition of a constant thickness of the applied solution. These data are indicated on the packaging and are indicative for calculation. The table below shows the characteristics of the glue of the most popular brands. The spread of the values is due to the different compositions of the mixtures and the type of application.

Variants of approximate calculation of the amount of tile adhesive

As you can see from the presented table, the values are approximately the same and there is not much to talk about. It is better to estimate the consumption of tile glue per 1 m2 on a calculator, which is presented by each manufacturer on its website.

In order to use this service, you need to know the area of the room, determine the size of the tiles and choose the type of mixture. As a result, you will be given a result in kilograms.

Another simplified version of the calculation under optimal conditions of use: half the thickness of the panel is multiplied by the consumption of the solution indicated on the package, the result is the required glue consumption per 1 m2.

In order to correctly determine the required amount of a mixture, it is necessary to take into account all the factors that affect this quantity.

Factors affecting the consumption of glue

The first thing on which the consumption of a mixture depends is the type of surface and its general state. The thinner the wall and the less irregularities and cracks on it, the less glue goes away. That's why professional builders recommend to pre-prepare the base with a less expensive finishing material such as plaster.

In addition, the back side of the tile can also have an uneven surface, and then an additional layer of solution is applied to it.

The next parameter that determines the required amount of glue is the material of the execution of both the wall and the tile itself. Each material has its own porosity, depending on which it has a certain absorbency. For example, walls made of concrete absorb the least amount of solution. To reduce the consumption of tile adhesive by 1 m2, the base before tiling is carefully treated with a deep penetration primer.

Tiles are also made of different materials. The most insignificant amount of glue is lost on the panel of porcelain stoneware, the largest porosity of the cotto tiles.

The size of the panels plays a role, too, than the larger the tiles, the thicker the layer should be.

Much depends on the way of laying and the professionalism of the masters. The finisher is more experienced, the more thin layer of glue he can put without losing the quality of fastening.

Types of glue

Before determining the consumption of tile adhesive for 1m2, you must choose which composition will be used. There are three main types of tile mix:

1. Dispersion - already ready-made, extremely convenient because it does not need to waste time preparing it. It is good because it has an ideal plasticity and viscosity, which allows to apply the solution optimally in a thin layer.

2. Cement-based glue, the most inexpensive mixture, which is sold in dry form and needs to be diluted. Thanks to the cheap components, it is very popular and is used in 80% of cases. For this species there is a way of calculating consumption, approximate, but giving at least some idea of the required quantity. To determine the flow rate, it is necessary to know the thickness of the adhesive layer, which is calculated from the size of the tile. Multiply the thickness by 1.3 (this is the average weight of the tile glue) and obtain the desired result.

3. Epoxy mixture is usually used by professional finishers, since its manufacture requires some experience. A special catalyst is used for breeding, which provokes a chemical reaction.

Spatulas used in operation

From the size and type of spatula also much depends. To apply the solution use a spatula of a certain shape. If it is incorrectly chosen in size, then the consumption of tile adhesive per 1 m2 significantly increases. On the packaging often indicated the recommended type of spatula, in this case it is better to obey the manufacturer and purchase it. In addition, it is recommended to adhere to the following rules:

1. The consumption of glue directly depends on the tilt angle of the spatula during application, the more the slope, the greater the consumption.

2. Most glue is consumed when applying mortar with a spatula with square teeth, the most economical option is the V-shaped tool.

So how much should you buy glue?

Experts propose to take the rate of glue consumption per 1 m2 - 10 kg at a layer thickness of 10 mm. Even if you are doing the tiling yourself, there will be more than enough. In order to reduce the consumption of tile adhesive by 1m2, the advice of professionals suggests carefully studying the technology of applying the solution and follow the recommendations from the manufacturer.
