Some tips for wall tiling

The surface of the substrate should be clean and smooth, free from residues of dirt, grease or paint. If you still find irregularities, you should seal them with an equalizing solution.
The glue solution can be applied only to a surface that is not larger than 1 sq. M. m., since it retains its properties only the first 10-25 minutes.
The beginning of laying the tile should go from the first solid tile from any angle. If you have batteries in this room, then you should place the tile on the appropriate heat-resistant adhesive near it, so that in the future there will be no problems.
When you are laying ceramic tiles on a wall, you must start from the first row from the corner. This way the uneven edges of the tile will be closed and not visible.
Ceramic tiles can be placed on the previously painted surface with the help of several rules:
Glossy paint should be treated with sandpaper, texture - completely level with a wire brush. By any means, to remove the paint, you can not use it;
Cut the tiles only with a glass cutter along the intended line with a pencil. It is better to work with special tools for cutting tiles, because if you use a glass cutter, then apply it to the table and forcefully break off a piece of tile, it can break in the wrong place, or there may be a chip;
It is possible to seal the seams only after 24 hours from the moment of laying the tile so that the adhesive solution can dry properly.
Many can not count the number of wall tiles. The first thing you need is just the height of the wall multiplied by the perimeter of the part of the wall to be trimmed. Next, to the resulting number, you should add another 5%. This is necessary to resolve some issues:
Some tiles, for example, porcelain stoneware under a tree will need to be drilled or trimmed, that is, adjusted to the overall pattern;
of course, there will be unnecessary parts of the tiles, but they can come in handy in the future, if you suddenly decide to dismantle some part of your wall or the corner of the room.
It is also worth noting that the design of the bathroom with ceramic tiles is easy to make, you will need borders, plinths, steps to the bath and much more. All this will help beautifully and comfortably decorate the bathroom, along with painting on ceramic tiles.
