Construction Techniques
Preparation and tools: Check the back of ceramic tiles, and clean any release agents and impurities. The application tools mainly include mechanical agitator, mixing barrel, measuring cup, notched trowel, putty knife, rubber hammer, horizontal ruler, tape measure, ink box or laser level, ceramic tile cutter, sponge, cross rubber particles, etc.
Substrate treatment:The substrate must be flat and true, clean, and free of oil, grease, wax stains, concrete curing agent or any loose materials. The flatness deviation of the substrate should be less than 3mm/2m.
Preparation of the tile adhesive:Volume of water is given in Certificate. Add water to the mixing bucket, and then slowly add the powders while mixing with mechanical agitator until a homogeneous paste without lumps is obtained. Wait 3 to 5 minutes prior to mixing again for 15-30 seconds. Finally, it is ready for use. The mixed adhesive should be used up in 2 hours.
Tiles paving:Apply forcefully a thin layer of the tile adhesive on the surface of substrate with spatula to enhance the bonding strength between the adhesive and substrate. And then apply a thick layer, and process the adhesive layer with notched trowel. Make sure that each coating area is not more than one piece of brick. Then press the tiles on the processed adhesive layer before drying. Under unfavorable weather condition (such as high temperature and wind) or for high water-absorbing substrate, tiles paving should be done as soon as possible. Before tiles paving, touch the adhesive layer with your fingers to check whether it is dried. If it is not dried yet, tiles paving can be conducted. Otherwise, adhesive layer should be applied again. The choice of trowel should be governed by the depth of the grooves or ridges on the back of each tile and the evenness of the substrate.
Announcements
During application, temperature should be 5℃~35℃; Avoid application in conditions such as rain, high temperature, wind, frost, etc.
Clear up the releasing agent on tiles’ backside before operation;
Tile joint gaps should be at least 2mm
Hold the notched trowel at an angle of approximately 60°from the substrate when combing.
