Why should artificial stone be treated with backside glue?

　　Organic artificial stone is an artificial building material composed of unsaturated polyester resin, crushed stone, stone powder, quartz sand and other materials.

　　Although the material is economical and environmentally friendly, the unsaturated polyester resin used as a binder can easily react chemically with alkaline water in cement, adhesives, etc. Therefore, if the artificial stone is not glued, the alkaline water will corrode the back of the artificial stone.

　　Adhesive treatment of artificial stone, in addition to the function of isolating alkaline water, the adhesive can also improve the bonding strength. At the same time, the adhesive is flexible, which can reduce stress and prevent hollowing and falling off to a certain extent.
