How to lay a tile in only six steps
1- CLEAN THE BASE
Be sure that the base is clean, dry, even, load-bearing and dust free. If you want to lay your tiles onto a board the base has to be fixed by scrawls. For absorption of vibrations you should use a shock absorber plate
2- SMOOTHEN UNEVEN SURFACES
Use a spatula or a smoothing trowel or self levelling mortar to smooth smaller cracks. You have to make a foundation before laying the tiles. Using a wide brush or a paint roller apply penetrating primer or bonding emulsion. Use deep penetrating primer or bonding emulsion. Use deep penetrating primer in rooms with high moisture content or in wet rooms (or where water could be splashed).
Use a tile cutting machine in order to achieve a straight edge on the tiles for the edges cut to size. Scratch the tile on the upper surface and brake it off by the edge.
In order to cut round opening use tile-cutting nippers (“parrot break”) and pinch off the opening by the millimeters or use a drilling machine equipped with a circular hole-cutter.
3- MARK THE MIDDLE OF THE ROOM
Having prepared the foundation measure out the floor area exactly and mark the middle of the room. First, as a test lay the tiles in a cross form
4- APPLY TILE ADHESIVE
Let it set for a short time then smoothen the adhesive using a spatula or a smoothing trowel. Use ready-to-use adhesive. If you lay the tiles on particle board/above floor heating use flexible tile adhesive. Smear the adhesive on 1-1,5m2 depending on the work-in-time of the spatula depend on the backside of the floor tiles, their size and the foundation.
5- START IN THE MIDDLE
Start to lay the first row of tiles measured to this and continue with the middle of the tiles or with a joint. Lay the next tiles by the wall.
