When you need to slow down the set time for your pool plaster mix, you can’t beat the power of Fritz-Pak’s Plaster Delay Set. This retarding pool plaster additive comes packaged in our signature water-soluble bag. It is the perfect product for those hot summer days when the plaster wants to set up faster than you can finish.

Why Use a Pool Plaster Additive

During hot, dry weather, the hydration rate of plaster accelerates because of the extra heat. When the plaster sets up too fast, it can weaken and crack. Using a pool plaster additive, like Plaster Delay Set, slow down the naturally occurring hydration. This way when the heat from the sun speeds up the hydration, it is still only setting up as fast as it normally does. The slowed hydration helps maintain the strength and durability of the plaster as it sets.

Benefits of Plaster Delay Set

Fritz-Pak’s Plaster Delay Set contains no calcium chloride or other corrosive materials, which can be destructive to pool plaster. After the manufacturing process, this pool plaster additive comes out as a white powder, which means it will not discolor the plaster during placement or as the pool is being filled. Finally, depending on what dosage is used, Plaster Delay Set can delay the setting time of the plaster by between one and three hours.
