SpecFilm Concentrate 
Evaporation retardant/finishing aid concentrate
SpecFilm Concentrate is an economical concentrate that, can be diluted with potable water up to a 9 to 1 ratio, providing a very effective evaporation retardant and finishing aid for concrete flatwork. Once diluted and sprayed over fresh concrete, SpecFilm forms a thin, continuous film which prevents rapid moisture loss from the concrete surface. SpecFilm is especially effective when concreting operations must be performed in direct sun, wind, high temperatures, or low relative humidity.
- Significantly reduces plastic shrinkage and cracking caused by evaporation in low humidity, high temperatures and high winds
- Allows use of lower slump and lower water to cement ratio concrete
- Reduces wind crusting, stickiness, and sponginess, which often cause poor and uneven surface texture.
- VOC compliant
- Aids in finishing concrete that produces little or no bleed water, like microsilica concrete mixes or concrete with no air entrainment.
Application
Before use, ensure SpecFilm is well-agitated. It’s best applied to fresh concrete right after screeding and, as necessary, between finishing operations to curb plastic shrinkage. In conditions requiring dry-shake hardener applications or when combatting severe drying conditions, re-application may be necessary. During typical weather, apply at a rate of 300-500 square feet per gallon, adjusting to 250-300 square feet per gallon as conditions dictate.
For optimal performance, dilute SpecFilm Concentrate with clean, potable water following a 5:1 ratio, although up to 9 parts water can be used. Mix thoroughly before application.
Packaging
SpecFilm Concentrate is available in 55-gallon drums, 5-gallon pails, and cases of four 1-gallon jugs.
Shelf Life
When stored properly, SpecFilm Concentrate has a shelf life of one year from the date of manufacture.
Standards
SpecFilm Concentrate aligns with the ACI 302 guideline for “Evaporation Retardant/Monomolecular Film,” ensuring industry-standard performance.
Cleaning
Cleaning of equipment should be immediate, using soap and water to prevent material buildup.
