Diamond Brite is a plaster/marcite product that contains either quartz or small stones. It is troweled on very similar to plaster and some of the cream is washed off at the end to expose some of the material. It is very difficult to get it exposed properly and the durability is questionable as the product contains calcium carbonate, which is damaged by acid.
Diamond Brite finish above water will have a dry appearance that will differ from the plaster below the water. Some check cracking may occur. Whenever possible, water curing of exposed areas for 7 to 28 days will lessen the occurrence of shrinkage cracking and increase the overall strength of the plaster.
The lifespan of Diamond Brite is generally longer than of plaster. Industry experience has shown that Diamond Brite pools, if maintained in a wet or moist condition, will typically have a lifespan of 7 to 15 years. In most cases achieving a 10 year life on a Diamond Brite surface is expected.
The Division 13 Cementitious Finish Specification includes a 3 year warranty on all cementitious finishes, including Diamond Brite.
The cost of Diamond Brite has a slight premium of approximately $2/SF when compared to plaster. However, when comparing life cycle cost the increased lifespan of Diamond Brite generally proves to be the better long term economic decision.
