WATER-BASE ACRYLIC CONCRETE CURE & SEAL
DESCRIPTION
VOCOMP-25 Water-Base
Acrylic Concrete Sealer is a ready-to-use concrete curing and sealing compound
formulated of special acrylic polymers in a true water-base 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. The VOC content of VOCOMP-25 is 200 g/ L, which is substantially less than the maximum limit of 700 g/L required by the US EPA Architectural Coatings Rule.
USES
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.

APPLICATION
Surface Preparation...Old Concrete: Surface preparation is extremely important.
Concrete 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,
or VOCOMP-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 commercial sprayer provides an easy, economical method of application.
VOCOMP-25 should be sprayed on with an 8001 tip 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, we recommend (2) 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 ... 12 hours is preferable.
Clean up...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.
PRECAUTIONS
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-BASE"
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 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.
HEALTH HAZARDS
Direct contact may result
in mild irritation. Inhalation may cause irritation of the respiratory tract.
