Application

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.
