Working time: Once the product is applied to the floor.
Open Time: Once the product is mixed and is still in the bucket.
Both working time and open time are greatly influenced by ambient temperature, material temperature and humidity. Concrete products lose their workability at 90 degrees so if the bags, water and Resin 221 are all 90 degrees or higher, then the material will not apply properly. We address hot weather application by NEVER diluting the Resin until a batch is ready to be mixed; this gives us the flexibility to use chilled or ice water for the mix. Ice water will extend open and working time significantly. Working time will additionally be affected by direct sunlight, substrate temperature and porosity and mix viscosity; installation of the adhesion enhancer according to instructions will prevent outgassing in porous floors and cool temperatures of hot substrates. Cooler weather conditions obviously have the opposite effect; open and working times are extended into undesirable gaps between application steps. Heated water, heaters to raise the ambient temperature and fans or blowers to move the air will all reduce working times.
