General information about ceramics and porcelain tiles
The differences between ceramic and porcelain tiles:
"granite porcelain" is a wrong expression - the correct definition is porcelain tiles.
There are several types of porcelain tiles : full body, polished, glazed, lapato, anti-slip, which come with various kinds of finishes - glossy, matte, etc.
The two main types of porcelain tiles are "pure porcelain" and "glazed porcelain."
Clay and homogeneous both side material. it is pure and a non-glazed material consisting of a high dose of kaolin (glassy) particles which gives the tile hardness and also enables its polishing.
has two main parts, the biscuit (similar to ceramic) and the glaze. the base layer (biscuit) is clay with organic ingredients with stronger and more compact particles, and the glaze usually is layers of paint.
Ceramics (Ceramics / gress)
It has two components: The basic ingredient is a clay (biscuit) that is the backing of the tile, and the glaze.
Both types go through the production process of high temperatures at levels of 1000-1200 ° C .
"joints " - fuga in Hebrew
There is a standard requiring ceramic tile flooring application and porcelain tiles.
The size of the joints should be 2-3 mm. Spacers - intervals are recommended to use for even joints.
The reasons for the use of joints filled with grout are to obtain a sealing, uniform flooring surface.
The more precise the tile, the narrower margin can be applied (minimum 2 mm as mentioned)
In addition, the grout is a sort of tile-to-tile shock absorber.
For your convenience, we have included a formula to help you calculate the amount of grout required:
Values in mm must be calculated with m"m :
(Tile length + tile width) / (tile length x tile width)
The result in the row must be multiplied by the thickness of the tile x the width of the interface x 1.5
For example, if we are dealing a 40 cm by 50 cm tile whose thickness is 6 mm , paved with a 3 mm wide joint, then the formula will look like this:
(400 * 500) / (400 + 500) = 0.045
0.045 * 6 * 3 * 1.5 = 0.12
This means that we will need about 120 grams of grout to cover a square meter.
For a 70 sqm compound of the same tile, we will need about 8.5 kg of grout.
