One year in an unopened container, stored in a dry area away from moisture.

Surface Preparation … Clean existing debris from all stamping tools. When working with a fresh concrete surface, ensure that the concrete is sufficiently set, and that all bleed water has dissipated from the surface to be worked on.

Application Method … Liberally apply SPECTRUM 920 powder stamp release by broadcasting the material over the concrete surface. Ensure that the surface is uniformly covered for proper release of the decorative concrete tools.

Place the decorative concrete texturing or stamping mats over the area that has been covered with SPECTRUM 920 powder stamp release. Using an impact tool, ensure that the concrete surface is adequately stamped for depth of texture. Remove the decorative concrete texturing mats from the concrete surface. SPECTRUM 920 powder stamp release should remain in a dry state on the concrete surface – the product should not be worked into the surface. Allow the concrete to set for a minimum of 24 hours.

Using a pressure washer and/or rotary floor machine, clean the concrete surface to remove any excess release agent. Do not attempt to remove excess release agent until concrete has attained sufficient strength. Premature removal of release agent may damage the concrete surface.

Sealing … Seal the concrete surface using DECRA-SEAL™ or DECRA-SEAL W/B from W. R. MEADOWS. If there is a concern that the surface may be slippery when wet, apply DECK-O-GRIP® or SURE-STEP™ from W. R. MEADOWS in the final coat of sealer applied to the concrete surface.

Cleanup … Tools may be cleaned with soap and water.

Avoid direct contact with this product as well as inhalation of dust. If dust is generated, the use of respiratory equipment (dust mask) is recommended. If contact with the skin or eyes occurs, flush area with water. Consult product material safety data sheet (MSDS) for complete health and safety information.
