Step 1: joint cleaning-the first step is to clean the joints of the tiles, that is, to clean the gaps of the tiles. After the tiles are laid, there will be cross, sand, cement and other sundries in the cracks of the tiles. We need to use a joint cleaning tool to clean the cracks in the tiles. For hard things, we need to use a seam cleaning cone and a sharp knife.
Step 2: Wipe the bottle mouth with a paper towel, then screw on the glue nozzle, compare the gaps between the tiles with the glue nozzle, and obliquely cut the angle of 45 degrees from below with a utility knife. Remember that the opening is smaller than the gap between tiles. If the gap between tiles is relatively small, there is no need for a glue cutter.
Step 3: Stick masking paper on both sides of the tile gap, so that the caulking agent will not run onto the tile. If it is convenient, don't stick masking paper, and then shovel it off with a shovel.
Step 4: You can squeeze the sealant. There are several colors of caulking agent. You can choose one you like. The color below is gold, which makes you feel good. When you squeeze, you should control the strength, be careful not to squeeze too much, do it piece by piece, and don't step on it when it's not dry, so as not to get all over the floor.
Step 5: Fill it in, and scrape and smooth the sewing agent with a hanging spoon.
Step 6: In the last step, press down along the gap with a sewing ball, and there will be a shallow depression, and the surface will look better and shiny after pressing down with a sewing ball.
Step 7: Wait for it to dry.
