Hot, dry weather conditions tend to accelerate the hydration rate of cement-based materials, including pool plasters. Using a plaster retarder, such as Fritz-Pak’s Plaster Delay Set, helps mitigate the impact of higher temperatures. One bag of this plaster retarder offers up to one hour of delayed setting time. Plaster Delay Set is a white, powdered admixture. It does not contain hazardous or corrosive materials and can be safely used with colored plaster mixes. It comes packaged in our signature water-soluble bag for easy use at the job site.
