PCAC-25

PRODUCT DESCRIPTION AND USE

PCAC-25 is a clear, solvent-based acrylic designed for sealing conventional concrete,
exposed aggregate, porous tile, concrete pavers, and a variety of architectural concrete surfaces.
PCAC-25  is based on a hard acrylic polymer that produces coatings that give excellent gloss, stain resistance, and clean ability. Adhesion to properly prepared cementitious surfaces is excellent
and the material is completely non-yellowing. PCAC-25 is produced in a standard formulation that
meets Arizona VOC requirements and a second formulation that meets the 100 gram/liter
California standard. Both formulations bring out the rich, natural beauty of the substrate.

Chemical Composition

High molecular weight thermoplastic acrylic resin dissolved in a specially formulated blend of
solvents.

Limitations

• Do not use on exterior on-grade flagstone, sandstone or slate.
• Use in heavy foot traffic areas requires regular maintenance coating.
• Will not resist solvents or brake fluid.
• Concrete must be absolutely dry.

GENERAL INFORMATION

            All interior concrete floors not poured over an effective moisture vapor retarder are subject to
possible moisture vapor transmission and related high levels of alkalinity that may lead to
blistering and failure of the coating system. It is the coating applicator’s responsibility to conduct
calcium chloride and relative humidity probe testing to determine if excessive levels of vapor
emissions or alkalinity are present before applying any coatings.   Paver Coatings can supply moisture remediation products.  Consult with our technical department.  Paver Coatings and its sales agents are not responsible for coating failure as a result of undetected moisture vapor emissions.

            Surface must be clean, sound and absolutely dry. Surface preparation should be done with a
floor machine and nylogrit type brush. Scrub the surface well using Pavercoatings.com Cleaner Degreaser
1 with water. Do not let cleaning solution dry on the surface. Rinse well with water and allow to
dry thoroughly before coating.

            PCAC-25 may be applied by brush, roller, airless sprayer or floor squeegee. If rolling the
material, use a 1/2-3/4 inch nap roller cover and work from a roller pan or 5 gallon pail. Use the
dip and roll method. Do not pour the material on the surface. Because the material dries quickly,
apply liberal amounts, work small areas and keep a wet edge. Distribute the material evenly by
slightly overlapping the area previously coated. Roll laterally across the body and roll again with
a vertical up and down motion. Application rates will vary from 200-400 sq. ft. per gallon
depending upon the texture and porosity of the substrate. PCAC-25 may be thinned with MEK,
Xylene or Acetone if desired. If using in California, use only Acetone to maintain VOC
compliance.

 

            PCAC-25 may be recoated with itself as soon as it is tack free, usually 20-40 minutes.  Recoating with itself after the material is fully cured requires that the surface be clean and dry.  No abrading is necessary. Recoating with other materials can be problematic and requires thorough cleaning and abrading.  Apply to a small test area and conduct a tape pull test prior to the main application. Contact factory for specific test  instructions.

 

            Material is flammable. Extinguish all flames, pilot lights and electric motors until all vapors are
gone and the coating is hard. The vapor is harmful. Do not use indoors unless area can be
properly ventilated. Use a cartridge type respirator during application. Avoid contact with skin,
wear protective gloves. Read Material Safety Data Sheet before using.

            OSHA and the American Disabilities Act (ADA) have now set enforceable standards for slip resistance on pedestrian surfaces. The current coefficient of friction required by ADA is .6 on level surfaces and .8 on ramps. Pavercoatings.com  recommends the use of angular slip resistant aggregate in all coatings or flooring systems that may be exposed to wet, oily or greasy conditions. It is the contractor and end users’ responsibility to provide a flooring system that meets current safety standards. Pavercoating.com or its sales agents will not be responsible for injury incurred in a slip and fall accident.
