Block-resistant gypsum board |
| 摘要 |
A predecorated printed paper on the gypsum wallboard with a clear washable coating over the printed paper, and having a thin coating of polyethylene emulsion on the back paper which overcomes the tendency of the coated predecorated paper to stick to the back paper of an adjacent board when the boards are piled in stacks for storage and shipment.
