Plaster Supreme is a white, dry powdered admixture packaged in a patented, ready-to-use, water-soluble bag. It is intended for use in pool plasters, to create a smooth, easily-spread plaster that reduces water loss and subsequent cracking. Plaster Supreme is a chemically active agent that improves the water retention of cement-based plasters, grouts, and mortars. In pool plaster, this reduces water loss from evaporation, thus eliminating the need for constant re-wetting in warm conditions. It also reduces water loss to the concrete shell. This allows for better cement hydration and a more even finish. Plaster Supreme also contains pumping additives that make the plaster more workable and easier to trowel. Unlike clay-based additives, Plaster Supreme will not leave residues that can promote discoloration or increased plaster cracking.

How will Plaster Supreme affect my plaster?
It will improve workability, reduce cracks, and increase water retention to reduce evaporation.
How does Plaster Supreme work?
Mainly, Plaster Supreme increases the level of entrained air in the plaster, making it easier to pump and spread. It also increases the plaster's ability to withstand cracking. Additionally the water retention agent will insure that the water does not evaporate from the plaster, thus creating a better environment for curing.
Does Plaster Supreme have any effect on plaster coloring?
Does Plaster Supreme affect the durability of plaster?
Yes. Plaster Supreme increases durability.
Does Plaster Supreme have a water reducer in the formulation?
Yes, plaster made with Plaster Supreme will require slightly less water, thus creating a stronger cement paste within the plaster.
