Category: Pool Plaster Products


Plaster Supreme is an additive designed to greatly improve troweling and workability of plaster while decreasing the incidence of shrinkage cracks. It increases water retention for a more even and controlled set. Contains no chlorides, nitrites, nitrates or clay.


  • Plaster Supreme improves workability, making plaster smooth and easy to spread.
  • Greatly reduces cracks.
  • Slows evaporation, increases water retention.
  • Will not affect set times.
  • Will not discolor white plasters, and helps colors mix evenly in colored plasters.
  • Contains no clay, only 10 oz required to treat a standard plaster batch.
  • Easy and safe to handle by workers.
  • English and Spanish usage directions on every bag.
  • Very easy to store and ship.
  • Prepackaged doses in patented water-soluble bags are simple to use.


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.


Plaster Supreme is compatible with most concrete admixtures. When used with other admixtures, each one must be dispensed separately into the mix.
