Question: What about mixing and warming the polyurea joint fill?
 
Answer:
. The “B” side must always be mixed/stirred before use. This re-blends the chemicals and pigments to ensure the product will be on-ratio and uniform in color. Warming the polyurea to approximately 70° helps keep the material in a nice flowable state. The colder the product, the thicker it seems; likewise, warmer material will be thinner.
