POLY-CHEMCURE PC-1703

100% SOLIDS EPOXY CONCRETE PRIMER

PRODUCT DESCRIPTION

V.O.C. COMPLIANT

PC-1703 is a specially formulated two component, 100% Solids Epoxy Concrete Primer. PC-1703 is a low viscosity, self leveling resin that can be applied at a dry film thickness of 5-10 mils in one (1) coat. It is designed as a concrete primer for use under epoxy mortar toppings, slurries, lining systems, and thin film epoxies and polyurethanes. The PC-1703 being a 100% Solids Epoxy, is ideal for use in confined areas where solvent odor is objectionable. It meets all EPA and other air pollution regulations.

SURFACE PREPARATION – CONCRETE

Gulf Coast Paint Mfg., Inc. recommends four types of surface preparation. Any one of the four surface preparations may be sufficient or a combination of the four may be required, depending on the condition of the concrete surface.

1. High Pressure Wet Abrasive Blast Cleaning

All loose and unsound concrete must be mechanically removed down to sound concrete by means

of power tool equipment, such as chipping, scaling hammers, rotary scalers, etc.

High pressure water blast all surfaces with sand injection to remove all laitance, contaminants, and

other foreign deposits to provide a sound, clean surface. Use clean, dry air to blow these areas and

to remove excessive moisture.

2. Acid Etch

Work the Acid Etch solution into the concrete with a stiff broom or fiber brush. Allow solution to

remain on the concrete surface for approximately 10 minutes, or until the effervescing and bubbling

ceases. Flush floor thoroughly with clean, fresh water to remove all laitance, dirt and other foreign

materials.

Random pH readings using distilled water should be made to insure all contaminants have been removed. A final pH between 7.0 and 8.5 is acceptable. Also, at the same time, it is recommended that a “Water Dissipation Test” be made on random areas of the floor to determine if the proper degree of porosity has been achieved.

Note: Do not allow the Acid Etch solution to dry on the floor before flushing off because dirt, etc. can be deposited in the pores of the concrete.

3. Vacuum Blast

All areas of the existing concrete shall be Vacuum Abrasive Blast cleaned using a Wheelabrator

Blastrac Shot Blast Machine with Dust Collector. A proper anchor profile pattern shall be achieved

to provide maximum adhesion of the recommended system.

4. Dry Abrasive Blast

Abrasive blast concrete surface to remove all laitance, loose concrete, coating, sealers, etc. It is

necessary to achieve a rough anchor pattern and get to sound concrete. All blast material and

foreign matter must be removed before application.

PC-1703/page 3

In all cases of surface preparation, the pH should be checked. A pH reading of 7.0 to 8.5 is acceptable. Also, a Water Dissipation Test should be made on random areas of the floor to determine if the proper degree of porosity has been achieved. A “Vapor Barrier Test” should also be run on the concrete. Consult Gulf Coast Paint Mfg., for specifics on testing.

New concrete must be cured at least a minimum of 28 days before applying a coating. All laitance, sealers, efflorescence, chemical contaminants, grease, oil, and other foreign material must be removed. The prepared surface must be clean, dry and structurally sound.

MIXING INSTRUCTIONS

PC-1703 is a 3:1 mixing ratio by volume, and is prepared by mixing 3 parts of Base (Part A) by volume with 1 part of Hardener (Part B) by volume with a Power Jiffy mixer. Blend the two components together for 2-3 minutes. Do not vary from the 3:1 mixing ratio. No thinning or induction time is recommended. PC-1703 should be used immediately after mixing.

APPLICATION PROCEDURE

For best results, apply PC-1703 with a roller or squeegee at 5-10 mils DFT. After applying PC-1703, immediately back-roll material with a spike or porcupine roller to break up any air bubbles formed by mixing or during application. If any concrete out-gassing occurs, roll 1-2 coats of PC-149 or PC-155 Concrete Primer directly to the concrete surface to help reduce out-gassing before applying PC-1703. The primer should be butterfly rolled into the concrete to provide uniform coverage. PC-155 Primer should be top coated while it is still “tacky”. Refer to the PC-155 Technical Data Sheet for specific information on recoating.

Note: For safety and product curing, proper ventilation is necessary throughout application and cure. When using pigmented Finish Coats, be sure the batch numbers are all the same to provide a uniform color.

PC-1703 is not designed for use in direct sunlight or in exterior applications, use suitable topcoats in all applications.

Do not apply if the surface temperature is within 5ºF of the Dew Point. PC-1703 Base and Hardener should be stored at 75 to 85ºF to help maintain a lower, rollable viscosity. Do not apply when material is cold. Allow a minimum of 72 hours with good ventilation before putting floor back into service. If a non-skid finish is required, prepare a test patch for owner approval prior to application. These systems are designed for application by professional experienced flooring contractors.

CAUTIONS

PC-1703 is COMBUSTIBLE. Keep away from all sources of ignition during storage, mixing, application and cure. PC-1703 Hardener is corrosive. The Hardener and base can cause eye and skin burns as well as allergic reactions. When spraying, the use of goggles, fresh air masks, or NIOSH approved respirators, protective skin cream and protective clothing is recommended as a standard practice.

The product is sold without warranty as to performance expressed or implied. Users are urged to make their own tests to determine the suitability for their particular conditions.
