Second, look at the stain resistance: the stain resistance of caulking agent is better than colored sand, and the experiment proves that the stain resistance of caulking agent is better.
Third, look at hardness and adhesion: the adhesion and hardness of colored sand and double-tube caulking agent are very good. As long as the gaps are completely dry and clean, there is no need to worry about them falling off.
Fourth, look at the construction: scrape the colored sand with a scraper to make the colored sand flush with the tiles; The double-tube sewing agent is pressed with steel balls or sewing pieces, which is slightly concave. If the flat seam tungsten steel sheet is used to press the joint filler, it can be similar to the tile, but the flatness of tile paving is very high.
To sum up, I summed up four words, that is, "watching the dishes and eating." If you want to be effective and economical, choose beautiful sewing agent, and if you want scrub, choose colored sand!
