Press All Grout Lines Firmly Make sure you press ALL grout lines firmly, and try NOT to touch the adhesive side as much as you can. Wall & Tile Temperature The temperature of the wall and tiles should be at least about 70°F for 12 hours before installation and 24 hours after installation. This is very important because if wall and tiles are cold, the tiles will not stick well. During the winter, the wall temperature is usually lower than room temperature so make sure that your walls are warm.
