Florida Stucco Gem Finishes, the etch resistant Marcite alternative, are a mill prepared Marcite alternative blended with the highest quality selected colored quartz aggregates, white Portland cement and proprietary additives to enhance strength, density, bonding and curing. A Gem Finish will yield a hard, long lasting surface highly resistant to stains and spot etching prevalent with traditional pool plasters. Exposure of the aggregate produces a safe, slip resistant and non-abrasive surface and comes in so many beautiful colors.
