Coatings for glass reinforced faced gypsum board

摘要: A coating method for gypsum board comprising forming a entrained with polymer additive in surface layer, applying preferably acrylic primary coating, curling and drying, passing the through first roll coater wherein second fluid is deposited over which forms chemical bond polymer, coating. material can form copolymer bonds then on same, dried cured, resulting coated having low tension surface, essentially impermeable to water, vapor or moisture penetration. In another aspect, at least one layer of capable applied either on-line off-line from formation line.
