Experienced craftsmen, knowing the footage of the room, looking at the base and at the tile chosen by the customer, can determine up to a kilogram how much mixture is needed. Nevertheless, the issue of the consumption of tile adhesive per 1 m2 is still one of the most common. The answer to it is for beginners in the decoration, as well as customers who are knocking down estimates of upcoming repair costs.
Tile adhesive consumption rates are shown on the dry mix packaging. Based on these data, the area of the room, as well as the required layer thickness, you can make a simple calculation of the consumption of tile glue.
It’s much easier to make this calculation on an official website or special application. You need to enter several parameters (length and width of the surface, wet room or dry, tile format, etc.) in order to instantly get information about the most suitable type of tile adhesive, as well as the required amount.
What determines the consumption of tile glue?
In order to correctly evaluate how much tile adhesive is required, several factors must be taken into account :
The curvature and general condition of the base.
The smoother the wall and the fewer holes, bumps, and cracks on it, the fewer glue leaves. Often, in pursuit of speed, they try to level the surface curvature using a layer of tile glue. Naturally, its consumption increases significantly.
By the way. In fact, neither in time nor in money, there is no special saving in leveling the surface with tile glue. Firstly, if you first plaster the surface, then you can win at the cost of materials, because plaster mix is cheaper than tile glue. Secondly, a layer of plaster + tile adhesive or just tile adhesive of the same thickness will dry for approximately the same time. The only thing that you need to spend time on the plastering works themselves, but this will be offset by the savings on tile adhesive and the ability to lay tiles faster and better, not to mention the pleasure of working on an even footing.
Type, format, and features of the tile.
For laying heavy, massive, large-format tiles, you must use the appropriate layer of tile adhesive. Often, the thickness of the layer of tile adhesive determines the depth of the relief on the back of the tile. We just can’t use a millimeter layer if there are more bumps in the back of the tile.
Type of spatula and application technology.
There is an opinion that V-shaped spatulas are more economical than U-shaped ones. Although in practice this is hardly confirmed. The choice of a spatula is more a matter of convenience for each particular master than a way to save. But the tilt of the tool really plays an important role. The optimal slope is 45 degrees. If you hold the spatula incorrectly, then the glue will go away by almost a third.
