QUESTION:  Can POLAR•SET Matrix be installed on a concrete driveway when temperatures are below 25°F and snow is present on the grass surrounding the driveway?

ANSWER:  Yes, but only when temperatures are above 20°F and only if the temperature is rising (4°–5°) during and after the application. The recommended temperature range for application of POLAR•SET Matrix is generally 20°F–50°F under dry atmospheric conditions. Note: The concrete surface temperature may also be lower than the surrounding air temperature which can complicate application and material set–up problems.

QUESTION:  How long does new concrete need to cure before applying PermaCrete?

ANSWER:  Concrete should cure for 7 days prior to application of PermaCrete. However, in very hot temperatures of 90°-100°F, PermaCrete can be applied after 3 days.

QUESTION:  Can a "broom finish" be applied to a PermaCrete texture coat on a horizontal concrete surface?

ANSWER:  Yes. A medium bristle, concrete broom can be used to create a broom finish, if it is pulled across the Matrix surface only using light pressure, because Matrix does not have the surface depth of poured concrete. Note: The Matrix should be tacky before application of the broom finish. Also, application(s) of PERMA•SEAL Stain Sealer or Clear Sealer should only be used after the application of the broom finish.

QUESTION:  Will PermaCrete harm marine wildlife such as fish when installed in a concrete pond?

ANSWER:  PermaCrete can be applied to a concrete pond, provided PERMA•THANE CRU–750 is applied as the sealer to minimize growth of algae, bacteria, and other natural contaminants that are detrimental to marine life. Note: Urethane sealers (such as PERMA•THANE ) contain gases that could be damaging to marine life during the cure cycle, but not after full cure when water and fish are placed in the pond. PERMA•THANE is fully cured after 96 hours at 72°F.
