U-Add POZ

Strengthen your pool's interior finish, Naturally

Universal's U-Add Poz™ is a plaster/marcite admixture that will turn the standard cement used in pool finishes into a high performance product. It will make your pool's plaster, pebble or quartz finish stronger and last longer.

U-Add Poz™ was specifically developed for the swimming pool industry. It is the only patented blend of pozzolans and has been installed in over 100,000 pools since 1995. What makes U-Add Poz™ unique is the formulation of different natural pozzolans that are combined in the correct percentages for the maximum results.

The blend of natural pozzolans in the U-Add Poz™ consume and reduce the amount of calcium hydroxide, a normal by product is the weakest part of cement and is the cause of many problems. Calcium hydroxide forms voids, which are unstable, weak, porous and are easily attacked by chemicals and aggressive water. Pozzolans reduce the amount of calcium hydroxide and turn it into a cementitious material forming a denser and tighter matrix. The improved water tightness significantly reduces the amount of water and chemicals that can infiltrate the plaster and cause the deterioration of cement. The increased strength of the plaster will provide many years of pool enjoyment.

Natural pozzolans were used in the Roman Era for construction purposes. True testimonials of pozzolanic strength and durability can still be found today in ancient structure constructed between 1550-2000 BC. Today pozzolans are required as an additive by many Federal agencies for structures such as bridges, dams and highways to improve durability and increase strength.
