Surface preparation: According to Neogard Guide Specifications.

Application conditions: Recommended air temperature: ≥50°F (10°C). Recommended relative humidity: 45–75%. Temperature of concrete must be at least 5°F (3°C) above the air dew point during coating application and cure time. Avoid application on a damp surface. Do not apply in the late afternoon if moisture condensation can appear during the night.

Subsequent coat: According to Neogard Guide Specifications.

Storage temperature: Store above freezing (32°F, 0°C). Freezing will cause 7779/7781 to become unusable. Do not ship or store unless protection from freezing is available. Do not apply if conditions will not permit complete cure before rain, dew or freezing temperatures occur.

Remarks: Avoid applying a thick film. Thick film increases cure time, especially at low temperature and high relative humidity, and may blister and crack on a hot concrete surface.
