    General rules for laying a mosaic tile floor

    General rules for laying a mosaic tile floor

    Mosaic tiles are made of small-sized slats and butt-joined. The sets of slats in the board are glued to the paper with the face side, or the face side to the mesh. Hence, depending on the material used to connect the slats in the board, they are glued to the base or with paper facing up, be a net for the ground.

    The substrate must be perfectly flat, so that the slats in the board adhere evenly to it. Otherwise, the so-called. keying and then the slats detach from the ground and successively fall out of the floor. Small irregularities can be leveled with glue, larger ones should be leveled with cement-sand mortar in relation to 1:1.

    A mosaic tile floor is basically laid out in a single checkerboard pattern. No other formulas are used, inter alia, due to the difficulties in precisely cutting the plates. The boards are laid in rows, starting from one of the walls. Each subsequent row is overlapped with the previous one in this way, to maintain the checkerboard pattern of the slats.

    Mosaic tiles are glued to a well-bonded and dried concrete substrate, with glue. The glue is a water emulsion, which penetrates the substrate and slats quite quickly. Therefore, it is good to lay the floor in two people. One spreads the adhesive over the substrate with a notched trowel, and the other applies the boards and presses them against the substrate. Each of the boards should be pressed against the substrate. The raindrops can be pressed with a heavy metal roller made e.g.. from a metal rod or tap them with a hammer. You should remember to keep the necessary 1-2 cm of play near walls, which is necessary, because in the first phase of sticking the board they absorb water from the glue and swell. Mosaic tile flooring is generally non-sagging and non-wedging. After 1-2 days, you can walk on it freely. However, sanding should be stopped for a few days (minimum 7) until the glue is completely dry and the water evaporates. During this time, the room should be intensively ventilated.
