Description
EUCOBAR RTU is a ready-to-use evaporation retardant and finishing aid for use on concrete surfaces of all types. When sprayed over fresh concrete, EUCOBAR RTU forms a monomolecular film that prevents rapid moisture loss from the concrete surface. EUCOBAR RTU is especially effective when concreting operations must be performed in direct sun, wind, high temperatures, or low relative humidity. EUCOBAR RTU is supplied pre-diluted, and does not require the addition of water before using.
FEATURES/BENEFITS
• Holds in surface moisture on concrete floors, slabs, and repairs
• Helps prevent plastic shrinkage cracking
• Easy and economical to use
• Helps eliminate crusting caused by loss of surface moisture
• Water based for total compatibility with fresh concrete
• Excellent for both interior and exterior concrete projects
• Will not affect adhesion of curing compound or other treatments
PRIMARY APPLICATIONS
• Floors
• Pavements
• Concrete toppings
• Vertical/overhead repairs
• Dry shake floors including all SURFLEX and EUCO-PLATE formulations
• Specialty iron toppings
• Parking decks and ramps
APPEARANCE
EUCOBAR RTU is a light pink liquid. The use of EUCOBAR RTU will not affect the color of concrete
COVERAGE
EUCOBAR RTU will cover approximately 200 to 400 ft²/gal (5 to 10 m²/L).
Coverage will vary depending on concrete texture and environmental (temperature, humidity, wind) conditions.
TECHNICAL INFORMATION
EUCOBAR RTU is a pre-diluted water based polymer. Evaporation rate is a function of relative humidity, concrete temperature, air temperature and wind velocity. Plastic shrinkage cracking is a strong possibility when the rate of evaporation exceeds 0.2 lb/ft²/hr (1.0 kg/m²/hr). The chart on the back of this page (Fig. 2.1.5 of ACI 305, Hot Weather Concreting) is useful in determining the evaporation rate under a given set of jobsite conditions. Use EUCOBAR RTU when the above limit is exceeded.
