USG Diamond Veneer Finish - Sanded is an economical way to give walls and ceilings a strong, hard surface that resists abrasion and surface cracking. It is preaggregated for convenience and higher productivity, dries in as little as 24 hours, and finishes to create a textured finish. USG Diamond Veneer Finish is formulated for hand application over USG Imperial Veneer Basecoat, or as a finish of a two-coat system over a sanded gypsum basecoat, USG Imperial Veneer Basecoat or USG Diamond Veneer Basecoat. USG veneer plaster systems offer the opportunity to trim days from interior finishing schedules and provide strong, highly abrasion-resistant surfaces.
