WR Meadows VOCOMP-25 – Concrete Curing & Sealing Compound

VOCOMP-25 – Concrete Curing and Sealing Compound

Water-Based, Acrylic Concrete Curing and Sealing Compound

VOCOMP-25 water-based acrylic concrete sealer is a ready-to-use concrete curing and sealing compound formulated of special acrylic polymers in a true water-based carrier. VOCOMP-25 provides improved resistance to rain, sun, freezing temperatures, most acids and industrial chemicals, petroleum, deicing salts, cleaning agents (except aromatic solvents), diluted caustics, and other pollutants.

VOCOMP-25 appears milky white in the container and, when first applied, leaves a bluish cast on the concrete for easy visual coverage. VOCOMP-25 dries clear to provide a transparent sheen finish. This sheen can be controlled by the number of coats applied.


VOCOMP-25 may be used wherever a medium-to-high sheen is desired to bring out the natural beauty of concrete without discoloring, checking, or peeling. It may be applied to simultaneously cure, seal, and dustproof new, old, interior, exterior, horizontal, and vertical concrete surfaces. VOCOMP-25 is ideal for curing, sealing, and dustproofing driveways, sidewalks, patios, swimming pool areas, and commercial and industrial floors. Horizontal surfaces protected with VOCOMP-25 offer excellent wearing qualities for foot and vehicular traffic. If, after prolonged usage, traffic patterns appear, the surface can be washed clean and recoated to restore the original beauty. Good concrete and good concreting practices should be followed, as VOCOMP-25 is not a cure-all for improperly mixed or placed concrete.

Surface Preparation … Old Concrete: Surface preparation is extremely important. Concrete curing must always be clean and dry, with all stains, oil, grease, dust, and dirt removed prior to application. If not, they will be amplified by the transparent sheen finish. CAUTION: If a liquid compound other than VOCOMP-20, VOCOMP-25, orVOCOMP-30 has been used, do not apply VOCOMP-25 until all traces of the compound have been completely removed and the surface is clean and dry. New Concrete:Apply VOCOMP-25 when the surface water has disappeared and the concrete surface will not be marred by walking workmen.

Mixing … For optimum performance, gentle mixing or agitation is recommended. CAUTION: DO NOT MIX EXCESSIVELY.

Application Method … A typical industrial sprayer, such as a Chapin 1949, provides an easy, economical method of application. VOCOMP-25 can also be applied using a lint-free roller or lambs wool applicator. Care should be taken to maintain a wet-edge during application to prevent roller marks in dried film.

VOCOMP-25 should be sprayed on with a Chapin 1-5916 nozzle that produces a flow of 1/10 of one gallon per minute. Spray on in a fine, fog pattern without spurts and dribbles to form a thin, continuous film. AVOID PUDDLING in low areas. If puddles occur, brush or roll them out. For added protection and a greater sheen on new or old concrete sealing , we recommend two coats of VOCOMP-25 be applied at right angles. Additional coats of VOCOMP-25 may be applied after the first coat has thoroughly dried.

Drying Time … VOCOMP-25 dries quickly. Drying times may be extended, depending on application rate, temperature, humidity, and project conditions. Restrict foot traffic for at least four hours. Twelve hours is preferable.

Cleanup … While VOCOMP-25 is still wet, equipment may be cleaned with soap and water. Once dried, the material may be removed with a solvent, such as xylene or toluene.

KEEP FROM FREEZING. Do not dilute. Do not apply VOCOMP-25 when air, material, and surface temperatures are expected to fall below 40° F (4° C) within four hours of completed application. DO NOT MIX WATER-BASED COMPOUNDS WITH ANY COMPOUND CONTAINING SOLVENT.

VOCOMP-25 may be applied to colored concrete, but mottling may occur. Do not use on dense or non-porous surfaces, i.e., brick, stone, etc.

Concrete Sealing floors properly cured with VOCOMP-25 meet section 8.9 “Adhesion of Tile Cements” of ASTM C 1315. For other specifications, secure the approval of the paint or resilient flooring manufacturer before applying VOCOMP-25. The specifier and user shall determine the suitability and assume all responsibilities in connection therewith.

Caution should be taken when applying to dense surfaces. Over-application or buildup of the film may result in the film being scratched by pallets or objects being dragged across it.

Direct contact may result in mild irritation. Inhalation may cause irritation of the respiratory tract. Refer to Material Safety Data Sheet for complete health and safety information.
