Disposal Dispose of  material, containers, solvents, etc.per Federal, State and local guideline, rules and laws
Available Colors Light Gray
Mixing & Installation Combine part A and B into a single container, large enough to accept the entire kit (1 mix equals 6 gallons when Part C is added). Premix liquids at 350 RPM for 1 minutes using an appropriate mixing blade or mixing machine. Pour material on to floor and spread to desired thickness using a screed rake and back roll techniques. If a broadcast has been selected, begin broadcasting evenly across the floor, following the same order in which the coating was installed. Whenever possible, work the shorter distance not the longer as this will help keep a fresh edge and make for easier blending. Recoat within 24 hours. Clean tools with a solvent similar to Xylene or Acetone.
