Grout consumption for tile joints

Regardless of how the laying of ceramic tiles, the seams between it are filled with a special solution - grout for joints Regardless of how the laying of ceramic tiles, the seams between it are filled with a special solution - grout for joints. The seam method of laying tile is more preferable than the butt-butt method for a number of reasons: tiles laid in this way do not fall off, do not crack, look more aesthetic, and seams hide all dimensional defects of ceramic elements. The ideal seam width for ceramic tiles of 15x15 cm in size is 1.5-2 mm, for parts of floor covering of 33x33 cm sizes it is 2-3 mm. The grout must be selected according to the tonal character of the tile.

Grout for ceramic tiles are available on cement and epoxy base. For traditional tiles, cement grout is used for tiles with a joint width of 6 mm. For pools and special types of floors with a seam width of 4-16 mm, special grouting is used to move and deform tiles without destroying the seam structure.

Grout consumption can be calculated depending on the area of ​​the lined surface and the size of ceramic tiles. For example, for standard floor tiles 30x30 cm, laid with a joint width of 2 mm, will require 300 grams of grout per 1 m2 of area. Grouting solution is prepared in strict accordance with the manufacturer's instructions, so that the resulting plastic mass qualitatively filled inter-joint seams. For a mosaic tile of the usual size of 5x5 cm and a seam width of 2 mm, it will take about 1 kg of dry grout, since such a significant expense is associated with the small size of mosaic elements and a considerable number of seams.

The formula for calculating the consumption of grout for joints

(A + B) / (A * B) * C * D * F = Kg / m2 (+ margin of 10-15%)

A - tile length (mm)

B - tile width (mm)

C - weld width (mm)

D - the depth of the seam (mm)

F is the volumetric weight of the grout, approximately 1.6

In order to grout the desired consistency, you must use a special latex or clean cool water, the temperature of which should be from +5 to + 35C. The mixture is gently mixed with a construction mixer at low speed to obtain a homogeneous mass without lumps. After the mixing process, a 5-10 minute pause is maintained, then the solution is mixed again, and only after that the grout is ready for use. Non-observance of proportions can lead to deterioration of the physical and chemical properties of the mash and increase its consumption. To work with grout should use special tools - rubber spatulas, which are available in different sizes and configurations.
