CS-309-25™ (formerly CS309-1315)
NON-YELLOWING ACRYLIC CURING AND SEALING
CS-309-25 meets maximum VOC content limits of 700 g/L for Concrete Curing and Sealing Compounds as required by the U.S. EPA Architectural Coatings Rule.
Once properly applied, CS-309-25 provides an impermeable
seal for efficient moisture retention. This produces a hard, dense,
high-compressive strength concrete. CS-309-25 will minimize hair-checking as
well as premature cracking, dusting, spalling and other common defects that
result when concrete is not properly cured. This economical, easy-to-use
compound dries quickly and protects the concrete during construction. It resists
adhesion of mortar droppings and permits easier clean-up. CS-309-25 also resists
discoloration or yellowing due to ultraviolet degradation.
The use of CS-309-25 on any exterior concrete surface
provides a durable long-lasting finish that has improved resistance to
chemicals, oil, grease, deicing salts and abrasion. CS-309-25 provides an
attractive, low sheen finish that enhances the natural appearance of the
concrete. If a higher sheen is desired, a second coat of CS-309-25 or a coat of
TIAH may be applied.
CS-309-25 should not be applied during high temperature conditions in direct sunlight. These conditions cause rapid evaporation, which does not allow the film to form properly. Under these conditions, the film may peel, bubble and/or turn white (blush).
CS-309-25 should not be applied to concrete exposed to excessive moisture. Entrapped moisture in a solvent based sealer may cause the film to peel and/or turn white (blush).
NOTE: For added protection and a greater sheen on new or old concrete, we recommend (2) coats of CS-309-25 or a coat of TIAH be applied at right angles. Additional coats may be applied after the previous coat has thoroughly dried; naturally, this may vary depending on temperature, humidity and project conditions.
DRYING TIME...CS-309-25 dries quickly. Drying times may be extended; again, depending on temperature, humidity, and project conditions. Restrict foot traffic for at least four hours...twelve hours is preferable.
NOTE: Use of fillers, extenders or additives in the concrete mix can result in a higher than normal porosity. To provide proper surface treatment, adjust coverage ratios to compensate for the resulting penetration.
