Plaster Bonder™ - 160207

For bonding new plaster to any structurally sound interior surface. USG Plaster Bonder™ is a vinyl acetate homopolymer emulsion used to bond new plaster to any structurally sound interior surface. The product is available clear, or tinted pink to allow visual confirmation of application where desired. It is a liquid that may be applied by brush, roller or spray in a uniform coating. When dry, USG Plaster Bonder™ forms a film that rewets when plaster is applied to provide an integral, strong, durable bond. Compatible with gypsum plaster, cinder block, stone, gypsum drywall panels and other similar materials; should not be used around swimming pools or in exceptionally moist or humid areas. Do not apply to underside of concrete roof decks. USG Plaster Bonder™ is required for applications of plaster over DUROCK® Brand Cement Board, FIBEROCK® Brand Abuse-Resistant Gypsum Fiber Panels and monolithic concrete. When applying the USG™ Decorative Interior Finish System, use only USG Plaster Bonder™ —Clear, since tinted (pigmented) bonder will show through the colored finish.
