1, Huang's craftsman is a brand specializing in sewing agents and has a good reputation. It is mainly recommended that the yellow craftsman set gold and drill porcelain as a beautiful sewing agent, which does not collapse or shrink, is heat-resistant and frost-resistant, and its products are tough and colorful, which can solve the problem of moldy and black cracks in ceramic tiles.

2. The beautiful and clean joint agent shrinks and collapses obviously after curing, and cracks are formed again, which is easy to hide evil people and shelter evil people, with poor adhesion, too soft, not resistant to pollution and scrubbing. So the royal family is good.
