When exposed to hot weather, mortar tends to set up faster than normal. Fortunately, Fritz-Pak’s Mortar Set Retarder offers up to one hour of set delay on even the hottest days. This product slows the hydration rate to keep the mix in a plastic state as you work with it. It does not affect the mix’s overall compressive strength or the color of decorative mixes. Mortar Set Retarder does not contain chloride or other potentially hazardous materials.
