If you want to remove tile adhesive from the tiles, it is recommended in two stages. The first dry cleaning. Make it with a special construction float. At the time of the execution of the works hold the tool at right angles to the surface of the tiles. Move the trowel diagonally, so as not to tear off the coating at the joints between tile. Don't forget to clean the tile adhesive must immediately, before it had time to dry and harden.
After dry-cleaning give the glue time to dry, then proceed to the second stage. Now remove the glue residue with warm water and sponge. Gently dampen the surface and wipe in a circular motion. So, gradually you will get rid of any imperfections.
If you hesitated and did not immediately removed the glue from the surface, causing it to harden, then use special tools. Such as construction, concentrated liquids or powders designed specifically for such work. Dilute them according to the instructions printed on the package, and then apply to the pollution and gently remove excess building material.
You can try to remove the glue and just mechanically with a spatula. However it must be done very carefully. Otherwise you can just ruin the surface of the tile.
You can remove the glue on the tile surface, and with ordinary vinegar. Wash very carefully, don't RUB, otherwise you'll scratch the tile, and the repair will have to redo it again.
If glue residue you noticed on the wall after we removed the old tile, then try them out using the means for washing the concrete. To tear using the tools useless and can spoil the surface, organizing it cracks and chips. If you use a special liquid, the removal of adhesive residues will be uniform and will be much softer.
