When laying inner and outer walls, the surface should be cleaned and wetted fully with water, and then plaster concrete mortar onto the opposite side of tiles equably with around 3mm thickness and stick immediately (especially notice that the concrete mortar satiation is a key step that’s often neglected by people). Tap with wooden hammer to fasten and even and level with ruler immediately to avoid empty space. Apply immediately after mixing the mortar and don’t lay aside for a long time.

　　When laying the floor, generally apply the mortar directly onto the surface firstly, with plastering width of not more than 1m and 30mm more than the tile width. Tap with wooden hammer, with mortar seam not more than 2mm (excluding the square tile and granite tile), and often level with ruler, better to leave expansion seam after sticking large area sideline. Leave an 8-10mm seam on the surroundings near the wall and later fill it in with wood bits and plaster thin concrete mortar on the surface.

　　If there are angular tiles, lay them first and stagger each other for long and short sizes. After laying angular tiles, lay even tiles from the edge to the center of the wall. Take directly out of the paper box according to some direction. When sticking products onto the wall, press solidly to let the sticking mortar overflow from around the product evenly.
