Surface Preparation
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 with sand injection all surfaces to remove all concrete laitance, contaminants, and other foreign deposits to provide a sound, clean surface. Use clean, dry air to blow down these areas to remove excessive moisture.

2. Acid Etch

Apply Gulf Coast Paint’s Clean & Etch Concrete Acid Solution at a spread rate of approximately 75-150 square feet per gallon.

Work the 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. Then flush floor thoroughly with clean, fresh water to remove all laitance, dirt, and other foreign materials.

NOTE: Do not allow the Clean & Etch solution to dry on the floor before flushing off because dirt, etc., can be redeposited 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. A thorough washing may be necessary prior to blasting to remove all foreign matter. Check with Blastrac Mfg. for propel shot and application procedures.

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.

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 that 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. Do not apply to slabs on grade unless a heavy unruptured vapor barrier has been installed under the slab All laitance, efflorescence, sealers, chemical contaminants, grease, oil, and other foreign material must be removed. The prepared surface must be clean, dry and structurally sound. Holes, cracks, spalled areas and other structural defects should be filled with CF-613 Crack Filler or PC-1000 Mortar. Rub smoother with a hand grinding stone to remove burrs or protruding aggregate.

Remove all dirt, oil, grease soil, chemical contaminants, and any other foreign matter before abrasive blast cleaning. Prepare and paint only clean, dry surfaces in accordance with Steel Structures Painting Council (SSPC) or National Association of Corrosion Engineers (N.A.C.E.) specifications.

Sand blast to a “Near-White” blast finish as outlined in SSPC-SP10-63T or N.A.C.E. No. 2 specification or sand blast to a “White Metal” blast finish as outlined in SSPC-SP5-63 or N.A.C.E. No. 1 specification. A 1-2 mil profile is required when blasting.

Primers: Prime all blasted steel within 4 hours to prevent rust from reoccurring. Apply 1 coat of PC-110, CM-15 or PC-636 Epoxy Coating depending on service.

Mixing Instructions, Application Procedure & Cure Time
Mixing Instructions
PC-650 is prepared by mixing 4 parts Base (Part A) to 1 part Hardener (Part B) with a 400-600 RPM explosion proof variable speed drill and Jiffy mixer. PC-650 may be thinned 5-10% by volume with SA-65 Thinner if necessary. Thinning will decrease the non-skid profile. Use immediately after mixing, no induction time is needed.Application Procedure
Do not apply until surface has been properly prepared. For best results prime concrete with PC- 149, or PC-155 Concrete Primer. On steel surfaces, prime with PC-110 Polyamide Primer, CM-15 Epoxy Mastic or PC-636 Epoxy. Allow primer to cure before applying PC-650. PC-650 should be applied with a Phenolic core roller, flatblade squeegee, or trowel. A core roller cover produces a uniform ridged surface. If a smoother surface is desired, use a trowel or a flat blade squeegee. Immediately after mixing pour a ribbon the PC-650 on to surface. The ribbon should be approximately 2-3 feet long and 6 inches wide. When using a Phenolic Core Roller pull the material towards you using some pressure. Do not over roll material this can decrease the non-skid. Roll material only in one direction. Strike off any excessive material build-up on edges from roller lap. The spread rate is approximately 30-40 sq. ft. per gallon. When using a squeegee or trowel, hold on 45 angle pulling material toward you. Pour a 2-3 inch wide ribbon. Apply at an even thickness at a approximate coverage rate of 40-50 sq. ft. per gallon. Do not apply over expansion joints. Do not apply if the surface temperature is within 5 of the dew point. Always apply a test patch of PC-650 for owners approval prior to application.Cure Time
For safety and proper product curing, good ventilation is necessary when painting indoors or in confined areas. Be sure the batch numbers are all the same to provide uniform color. Epoxy coatings may yellow or darken during application and after final cure. This will affect the color but will have no effect on the performance of the product. Heaters that emit carbon dioxide and carbon monoxide can cause the coating to yellow.
PC-650 is flammable. Keep away from all sources of ignition during mixing, application and cure. The HARDENER and BASE can cause eye and skin burns as well as allergic reactions. The use of goggles, fresh air masks or NIOSH approved respirators, protective skin cream and protective clothing. This 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.
