SpecFilm RTU Green Conscious Product

Ready-to-use evaporation retardant/finishing aid

SpecFilm RTU is crafted for use as an evaporation retardant and finishing aid on all types of concrete flatwork. Applied via spraying on fresh concrete, it creates a protective film to inhibit rapid moisture loss. It’s particularly beneficial in conditions prone to rapid evaporation, such as direct sunlight, wind, high temperatures, or low humidity.

  • Dramatically reduces the incidence of plastic shrinkage and cracking by maintaining moisture, especially in harsh environmental conditions.
  • Enables the use of concrete mixes with reduced slumps and water-to-cement ratios.
  • Mitigates issues like wind crusting and uneven surface textures, ensuring a smoother and more uniform finish.
  • Features a pink dye as a visual aid to ensure thorough application. Fully compliant with VOC regulations.
  • Designed to minimize surface cracking in concrete types prone to early water loss, such as silica fume concrete.
  • Pre-diluted to an optimal 5:1 ratio for immediate use, guaranteeing maximum effectiveness.
  • Facilitates the finishing of concrete and repair mortars that typically produce minimal bleed water, like microsilica or non-air entrained mixes.

Before application, ensure SpecFilm RTU is well agitated. Apply to fresh concrete immediately after screeding and as necessary between finishing operations to avert plastic shrinkage. During dry-shake hardener applications or under severe drying conditions, multiple applications may be required. Apply under standard conditions at a rate of 300-500 sq. ft. per gallon. In more extreme drying conditions, increase the application rate to 150-300 sq. ft. per gallon. Avoid over-application.


SpecFilm RTU maintains a shelf life of one year from the date of manufacture when stored in its original, tightly sealed containers. Keep containers free from water, dirt, and other contaminants.
