VOCOMP®-30

WATER-BASE ACRYLIC CONCRETE CURING AND SEALING COMPOUND

Description
VOCOMP-30 is a ready-to-use, 30% solids Concrete Curing and Sealing Compound formulated of special acrylic polymers in a true water-base carrier. VOCOMP-30 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.

Color-wise, VOCOMP-30 appears "milky-white" in the container and when first applied, leaves a "bluish" cast on the concrete for easy visual coverage. VOCOMP-30 dries clear to provide a transparent sheen finish. This sheen can be controlled by the number of coats applied. VOCOMP-30 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.

Uses
VOCOMP-30 may be used wherever a thicker film, with a medium to high sheen, is desired to bring out the natural beauty of concrete without discoloring, checking or peeling. When properly applied, VOCOMP-30 provides an impermeable seal for superior moisture protection. It may be applied to simultaneously cure, seal and dustproof new and old, interior and exterior, horizontal and vertical concrete surfaces. VOCOMP-30 is ideal for curing, sealing and dustproofing driveways, sidewalks, patios, swimming pool areas and commercial and industrial floors. Horizontal surfaces protected with VOCOMP-30 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 used as VOCOMP-30 is not a cure-all for improperly mixed or placed concrete.

Features and Benefits

• Provides a ready-to-use, non-yellowing, water-base compound that seals and protects concrete in one quick and easy application
• Dries quickly on new concrete to provide a clear, tough, easy-to-clean sheen finish
• Applicable for use on new, old, interior, exterior, horizontal and vertical concrete surfaces
• Offers improved resistance to most chemicals, petroleum, abrasives and mortar droppings
• Application tools can be cleaned with soap and water
• VOC compliant...actual VOC content is less than 200 g/L

APPLICATION
Surface Preparation...Existing (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-30 until all traces of the compound have been completely removed and the surface is clean and dry. New Concrete: Apply VOCOMP-30 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: TO AVOID FOAMING, DO NOT MIX EXCESSIVELY.

Application Method...A typical commercial sprayer provides an easy, economical method of application. VOCOMP-30 should be sprayed on with an 8001 tip that produces a flow of 1/10 of a 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 existing (old) concrete, we recommend (2) coats of VOCOMP-30 be applied at right angles. Additional coats of VOCOMP-30 may be applied after the first coat has thoroughly dried.

Drying Time...VOCOMP-30 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-30 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-30 when air, material and surface temperatures are expected to fall below 40°F(4°C) within 4 hours of completed application. DO NOT MIX "WATER -BASE" COMPOUNDS WITH ANY COMPOUND CONTAINING SOLVENT.

VOCOMP-30 may be applied to colored concrete, but mottling may occur. Do not use on non-porous surfaces or surfaces which are not uniform in porosity, i.e., brick, stone, masonry, etc. Concrete floors properly cured with VOCOMP-30 meet section 8.9 "Adhesion of Tile Cements" of ASTMC 1315. For other specifications, secure the approval of the paint or resilient flooring manufacturer before applying VOCOMP-30. 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. Refer to Material Safety Data Sheet for complete health and safety information.
