Although the floor tiles are very practical and can add brilliance to the family, after the tiles are used for a period of time, there will be many problems, so it is very important when repairing the tiles. The following Xiao Bian introduced the method of repairing the floor tiles and the identification of the floor tiles.
Method for repairing floor tiles 1. When repairing floor tiles, you can use fine sandpaper to dip water on the walls, remembering that it must be wetted. This method has a good effect on small scratches.
Repair floor tiles method Second, for some floor tiles that are difficult to bitch out, you can use epoxy glue to coat the back of the tiles with a thin layer, which can keep the new tiles flush with the surrounding tiles.
Repair tile method 3, the tiles are still intact, but with other junctions off, this time repair as long as the joints of the sand removed ash, and add epoxy adhesive, dry joints and then with a waterproof flexible The caulking material is embedded.
Tiles are good or bad
1. See if the color of the floor slab is uniform or not. Generally, the floor slab is of good quality and the color of the slab is uniform and uniform.
2, to see whether the tiles cross-section surface fine, if the fracture is fine, hard and crisp, uniform color for the top grade. For tiles with larger particles, moisture can easily infiltrate and affect quality.
3, you can gently tap the floor tiles, listening to the sound is crisp, if the sound dull, quality problems.
4, can test the water, look at the speed of tile water absorption, and then look at the front left the mark is obvious, if the water is not obvious, it is regarded as top grade.
5, with ink painted on the top after waiting for an hour and then scrub whether there are traces, if the ink will infiltrate, resolutely not selected.
6, can compare the test report of the national testing agency, compare the data to see if it meets the national standard.
Editor's summary: The method for repairing floor tiles and the identification of floor tiles are introduced here. I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
