Spray Film is effective in combating rapid drying of the surface during adverse conditions including high temperatures, low humidity high winds, direct sunlight or interior work in heated conditions.
Uses
- Fresh concrete surfaces where the evaporation rate exceeds the rate of bleeding of the concrete.
- Exterior placements during times of low humidity, high wings, direct sun or temperatures exceeding 75°
- Interior placements in heated areas or with low humidity or areas subjected to drafts
- Large dry shake placements where surface moisture must be retained for proper installation.
Advantages
- Reduces surface moisture loss by approximately 80% in windy conditions and 40% in direct sunlight.
- Will not interfere with the adhesion of subsequent curing & sealing compounds.
- Reduces crusting, stickiness and sponginess which may cause uneven or poor surface texture.
- Reduces plastic shrinkage cracking and wind crusting on flatwork.
- Allows lower water content in concrete mix since Spray Film eliminates the need to add extra mixing water to the mix to compensate for rapid evaporation during finishing.
- Keeps the surface plastic and finishable for a longer time.
