How to Use Mortar Set Retarder

When adding a mortar delay set admixture to your mortar mix, it is very important to thoroughly mix the retarding agent into the batch. Otherwise, you may not achieve the desired set delay time or the delay time may be unevenly applied to the project. For the best dispersion of our product, Fritz-Pak recommends adding Mortar Set Retarder to the mixer and then mixing at a high speed for at least five minutes.
