First, we measure the horizontal lines (5 rows of tiles) from the top of the adhesive base. The height can be marked using ropes or laser spirit levels. Apply the glue with a notched trowel (comb) with a tooth size of 4 mm. The area covered with the adhesive needs to be done in around 10 minutes – do not use excessive adhesive, work in small areas. The ideal gluing temperature is +10-20 °C. Due to high humidity or cold weather the setting time of the glue can be longer. Tiles may not be glued if the ambient temperature is expected to be lower than +5 degrees Celsius within 7 days of gluing the tiles.
The tiles are pressed into the glue so that its back side completely adheres to the special glue. The standard seam width is 12 mm. The seam width can be changed as desired. It is recommended to use corner tiles on 90º corners, or you can stick tiles on corners in two ways: bend the tile on a slightly rounded corner or cut it, joining the corners and covering the resulting gaps with an adhesive mass of the same color, but there is a chance that cracks will appear when bending the tiles.
Tiles are easily cut with scissors or using a sharp knife.
Level the glue between the tiles with a damp 10 mm wide brush. It is important that the adhesive gets even under the tile and no water can get between the tile and the adhesive.
