VOCOMP®-20

WATER-BASE ACRYLIC CURING AND SEALING COMPOUND
Cures and/or seals interior or exterior concrete surfaces in one easy and economical application.

SEALTIGHT VOCOMP-20 Water-Base Acrylic Curing and Sealing Compound is a ready-to-use, non-yellowing, true water-base liquid compound designed to cure and/or seal new concrete in one quick and easy application.

A potable water approved product (in accordance with Standard ANSI/NSF 61-1997B 69RL) is available upon request. A copy of this approval is also available upon request.

Technical Description
SEALTIGHT VOCOMP-20 Water-Base Acrylic Curing and Sealing Compound is formulated of special acrylic copolymers in a true water-base carrier. It is a ready-to-use curing and sealing compound.

Once properly applied, VOCOMP-20 provides an impermeable seal for efficient moisture retention. Color-wise, VOCOMP-20 appears "milky white" in the container and, when first applied, it leaves a "bluish" cast on the concrete for easy, visual identification of coverage. VOCOMP-20 dries clear to provide a transparent sheen finish. If a greater sheen is desired, a coat of VOCOMP-25 or VOCOMP-30 may be applied. (Refer to catalog Nos. 369 1nd 374).VOCOMP-20 resists yellowing due to ultraviolet degradation and provides a durable, long-lasting finish that offers improved resistance to chemicals, petroleum and abrasives.

VOCOMP-20 will minimize hair-checking, premature cracking, dusting and spalling. However, good concrete and good concreting practices should be used as VOCOMP-20 is not a cure-all for improperly mixed or placed concrete. VOCOMP-20 meets maximum VOC content limit of 350 g/L for Concrete Curing Compounds as required by the U.S. EPA Architectural Coatings Rule.

Uses
VOCOMP-20 Water-Base Acrylic Curing and Sealing Compound may be quickly and easily applied to simultaneously cure and/or seal new interior and exterior, vertical and horizontal concrete surfaces. It is ideal for application on commercial and industrial floors, sidewalks, basement and garage floors, multi-level parking decks, patios, driveways and parking areas. VOCOMP-20 dries very quickly to protect and enhance the natural appearance of concrete.

Features and Benefits

Application Tools

Application
SURFACE PREPARATION... NEW CONCRETE: Apply VOCOMP-20 when the surface water has disappeared and the concrete surface will not be marred by walking workmen.

APPLICATION METHOD... VOCOMP-20 is ready-to-use "as is" from the container. A typical, manual sprayer provides an easy, economical method of application. VOCOMP-20 should be sprayed on with an 8001 tip that produces a flow of 1/10th 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.

DRYING TIME...VOCOMP 20 dries very quickly. Restrict foot traffic for at least 4 hours...12 hours is preferable.

NOTE... For added protection and a greater sheen on the concrete, a coat of VOCOMP-25-1315 may be applied after the first coat of VOCOMP-20 has dried. Naturally, drying time may vary depending on temperature, humidity and project conditions.

CLEANUP: While VOCOMP-20 is still wet, equipment may be easily cleaned with soap and water. Once dried, the material may be removed with a solvent such as Xylene or Toluene.

Packaging
1 gallon (3.79 liter) Cans (6 per case)

Complies with the ultraviolet light degradation - yellowing classification of ASTM C 1315, Class A, Section 6.4.1.

Coverage
Approximately 300 ft.²/gal. (7.36m²/L). Coverages may vary due to porosity and condition of the concrete.

Precautions
Keep material from freezing. Do not apply if temperature of the concrete is less than 40ºF (4ºC).
Do not paint or apply resilient flooring over VOCOMP-20 without first checking the specifications and securing the approval of the paint or resilient flooring manufacturer. VOCOMP-20 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.

NOTE: Concrete floors properly cured with VOCOMP-20 meet Section 8.9 "Adhesion of Tile Cements" of ASTM C 1315. Read and follow application information, precautions and Material Safety Data information.
