Norms for Tile Glues

(Based on about 1 sq. yd)

There is no getting away from the glue during repairing. However it brings up another point, how much glue to buy, for example, for laying tiles? It seems that it will be better to have more glue than not enough, say, in the middle of the repair. To solve this problem you need at least to calculate the cost of repairs.

Thus, the tile glue is usually packed by the pounds. Therefore, you need to determine the consumption of glue per about 1 sq. yd (square yard), and then calculate the total amount based on the area of the room. But, the simple answer to the question, how much tile glue consumed in about 1 sq. yd − no. It all depends on many factor.

1) Type of glue

The tile glue is divided into three groups:

- dispersion,
- epoxy,
- cementitious.

The most economical and easiest variant for working glue based on cement (diluted with water). Depending on the layer thickness, the average consumption of it is between about 2-4 lb (pound). Dispersion glue is ready for use; it is based on resin and has a liquid structure. An epoxy glue also has a resin in its composition which when used it is added to the catalyst.

2) Size of tiles

The larger the tiles, the heavier it is, so the thickness of the glue layer must be more. So, for tiles of size about 4 x 4 in. (inch) desired a layer of cement glue, about 79 mil (fractional mille), for tiles about 8 x 12 in. – about 118 mil, for tiles about 12 x 12 in. or more – about 157-197 mil.

To measure the thickness of the glue base is quite difficult. Even if the glue layer will look smooth, in reality it may not be so. So, rely on the size of teeth of the trowel. So, for tiles about 12 x 12 in. it is suitable a trowel with teeth 315 mil.

When applying the glue with a trowel it must be kept under an angle of 90 degrees relative to the wall, only then the thickness of the glue layer can be more precise. For the optimal distribution of the glue it is necessary to apply at first the trowel without teeth and then to hackle the glue's basis. Therefore, the glue consumption depends on the size of the spatula (this is often stated in the instructions). So, for example, if you use the glue Ceresit CM12, the flow rate will be about 9 lb per 1 sq. yd, provided that you use a spatula with teeth 394 mil for the tiles of about 12 x 12 in.

3) Kind of tiles

Different kinds of tiles absorbs different amount of glue. The granite absorbs the least glue, a little over – the glazed tiles, and finally, the most glues are absorbed by a porous surface of the Cotto tiles (hand-made tiles also absorb a lot of glue).

In addition, if the tile surface is irregular, then it will additionally have to lay a small layer of glue, which will be increased its consumption.

4) Glue spread − technology of laying tiles and substrate type

An ideal surface for laying the tiles must be smooth, flat, not have cracks. In this case, the glue consumption is minimal since it is only necessary to ensure adhesion of the tile surface.

If the surface has swings, cracks, they often compensate by leveling glue. There are specially designed glues, which also line the wall. Usually these are used if the difference of the variations is greater than about inch. So this glue will need for laying a tile that has swings on the back side, for example, for a clinker.

There is a diverse porosity not only at the backside of tiles, but and at the surface on which the last are coated. The higher porosity, the more glue is absorbed. And, then, to secure the tiles will require additional costs. For example, concrete walls absorb less glue than with the cemented base.

5) Composition of glue and brand are nevertheless important

The glue composition includes various additives that give it certain properties (frost resistance, etc.). Accordingly, these additives are changing of glue structure, making it liquid or vice versa more viscous. Therefore, the consumption of different brands glue, but of the same volume, could be different.

As a result, for each type of glue and glue for a specific brand name there are their own rates of application. For example, to glue K80 Litokol the norm is a little more − 3 lb.

6) Weather conditions also affect technique works

The optimum temperature is suitable for laying tiles in the range of about 640-770 F (Fahrenheit). But the limits are much broader: from about 410 to 1000 F. The higher the temperature in the room, the more glue you will need, because the moisture evaporates very quickly. The glue can lose its properties in freezing temperatures.

7) Glue consumption depends on technique and skills of specialist

The quantity of consumed glue depends on the technique of its application. So when you tilt the trowel with an angle of 65 degrees, the glue consumption will be greater than of 45 (the difference amounts to 20-30 percents). The shape of the spatula can also play a significant role. It is better to work with a V-shaped form spatula or with a U-shaped one. A higher consumption of glue falls on the spatula with the tines of a square shape. Moreover, the glue flow by the specialist with his rich working experience will obviously be less than by the amateur. So if you lay tiles for the first time, it is better to buy the glue with the stock.


Calculation of glue amount

There are several ways to calculate the necessary amount of glue:

The first variant is suitable for those who buy glue again, worked with it and knows all the features of the glue consumption of this brand. In this case, buying glue, you can go to the official website of the company representative. Very often such sites offer the option for calculation – a virtual calculator. You only need to enter data on the tiles size, the square footage of dwelling and the specific type of glue. The final answer you will receive in pounds.

The second variant. We offer you a rough calculation of the consumption of glue based on cement. Take the most favorable conditions, glue spending weight about 3 lbs (pounds). Multiply this value by the thickness of the glue layer (for example that a tile has a size of about 12 x 12 in., then the thickness of the glue layer is equal to 157 mil). The received result: about 11 lbs − per about 1 sq. yd. For tiles of other sizes, the only change is the increased thickness of the glue base. However, this result is difficult to give absolutely exact, though, because all glues are different. However, a rough estimate will give you some point of reference.

The third variant – perfect for those who urgently need to know how much glue will be needed for about 1 sq. yd.

This requires the following parameters: half the thickness of the tile (fractional mille), average consumption of purchased glue. Multiply these figures and obtain the result. This method is very approximate because even a porcelain tile from the same batch has a different thickness.


Most Popular Brand of Glue: Rate of Consumption

We offer to your attention the average spending of the glue per about 1 sq. yd of the most popular, having the highest quality, the construction industry brands.

First, let us consider the general dosage, where the first figure − is the rate of glue spending in ounces (oz) per about 1 square yard (sq. yd); while the second component − is the thickness of the adhesive layer in fractional milles (mil):

- Ceresit glue: about 49-56 oz per 39 mil of the glue/3-13 lb per 79 - 315 mil;
- Litokol glue: about 46-53 lb per 39 mil of the glue/6-13 lb per 79 - 315 mil;
- Mapei glue: about 42-56 lb per 39 mil of the glue/4-18 lb per 79 - 315 mil.

Well, and now we offer you detailed results of the glue spending.
