Abstract (en)

[origin: WO02058902A2] A gypsum board is coated with a coating (32) during the manufacturing process to form a coated gypsum board. Coatings are applied to wet gypsum boards before being dried (325) in the oven and coating penetrates through at least a portion of the facing sheet and into the gypsum core of the gypsum board. Rapid coating compositions allow faster installation; quick setting compositions provide for more durable finishes. Either coating may be made lightweight by addition of perlite and may have enhanced finish appearance by incorporating pigments. A coated gypsum board can be fastened to a support structure to form a wall and the seams between adjacent coated gypsum boards can be taped and finished using a joint compound having a composition substantially similar to the composition of the coating. Overall, the resulting coated gypsum board and the method used to produce it help to improve final finish appearance and to reduce manufacturing time and costs.
