SpecFilm Concentrate

Evaporation retardant/finishing aid concentrate

SpecFilm Concentrate is a cost-effective solution designed to control moisture evaporation in concrete flatwork, enhancing durability and finish quality. Dilutable with potable water at ratios up to 9:1, it forms a protective film over fresh concrete to prevent rapid moisture loss, essential in conditions of direct sunlight, wind, high temperatures, or low humidity.

  • Mitigates plastic shrinkage and cracking by preserving moisture in harsh conditions.
  • Facilitates the use of concrete mixes with lower water to cement ratios for enhanced strength and durability.
  • Promotes a smoother and more resilient concrete flatwork surface.
  • Minimizes surface imperfections such as wind crusting and uneven textures.
  • VOC compliant for environmental safety.
  • Supports the finishing of challenging concrete mixes, such as microsilica or those with reduced air entrainment.

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.


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.


SpecFilm Concentrate aligns with the ACI 302 guideline for “Evaporation Retardant/Monomolecular Film,” ensuring industry-standard performance.


Cleaning of equipment should be immediate, using soap and water to prevent material buildup.
