EVRT (EVAPORATION RETARDANT)
EVRT is a ready to use water-based evaporation retardant for concrete flatwork. EVRT reduces surface moisture evaporation in rapid-drying conditions (high temperature, low humidity, wind and direct sun).
EVRT, when applied over fresh concrete, creates a monomolecular film retarding the moisture loss from the concrete surface, allowing time for proper finishing and help in preventing plastic shrinkage of the concrete slab.
- Ready to use formulation – no mixing
- Retains needed surface moisture in concrete slabs
- Helps prevent plastic shrinkage cracks
- Reduces crusting and stickiness, allowing easier troweling of the concrete surface? Promotes higher strength, more durable concrete by allowing lower slump concrete without the need for additional mix water to combat effects of evaporation
- Allows additional time, when applying surface hardeners, to properly finish and later cure the slab
- Allows easier finishing of polymer, fiber reinforced, or silica fume-modified concrete mortar mixes
- Effective for both inside and outside flatwork
- Will not inhibit bonding of coatings nor alter the final color of the concrete
