|Recommended as a deep penetrating sealer to protect new and old concrete surfaces from attack by chemicals, water, and effects of freeze/thaw cycles. The resulting tight film helps prevent “dusting” of the concrete, spalling, and deterioration.
Excellent industrial concrete sealer for warehouse floors, parking decks, concrete slabs and walls, bridges, loading docks, exterior walks, runways, dams, driveways, garages, aircraft hangars, and secondary containment areas. PC-149 can be made into a non-skid finish.
Used as a primer for Gulf Coast Paint’s PC-200, CM-15, PC-500, PC-517, PC-555, Epoxies; CT-352, and CT-370 Polyurethanes.
|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
3. Vacuum Blast
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.
|Mixing Instructions, Application Procedure & Recoat Time|
PC-149 is prepared by mixing 1 part Base (Part A) to 1 part Hardener (Part B) with a power mixer. Allow an induction time of 30 minutes before using. Thinning is not required.Application ProcedureFor best results, use a medium nap, phenolic core roller. Apply a uniform wet film while working material into surface. Do not allow material to “puddle”. Spread rate will be approximately 175 to 250 sq. ft. per mixed gallon, depending upon porosity of concrete surface. One or two coats may be required. PC-149 may be sprayed, men “back-rolled” to produce a uniform coat. May be applied with a pure bristle brush.
Do not apply to surfaces below 50 F. or above 120 F. Do not apply if the surface temperature is within 5 of the Dew Point. PC-149 Base and Hardener should be stored at 75 F – 85 F. 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. PC-149 is not recommended as a finish coat in areas where there is direct sunlight. PC-149 Gray is not recommended as a finish coat due to its very light pigment loading. Not recommended on floors susceptible to hydrostatic pressure.
|PC-149 is flammable. Keep away from all sources of ignition during mixing, application and cure. The HARDENER (Part B) and mixtures of BASE (Part A) with HARDENER (Part B) can cause eye and skin bums as well as allergic reactions. The use of goggles, fresh air masks or NIOSH approved respirators, protective skin cream and protective clothing is a recommended standard practice when applying coatings.
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.
PC-149 is for industrial use only
Prime-Crete PC-149 Clear Epoxy Penetrating Primer-Sealer
A low viscosity, two component, clear, polyamide modified epoxy primer/sealer formulated with unique wetting agents to provide maximum penetration into concrete surfaces. PC-149 seals concrete surfaces from penetration of water and chemicals which cause concrete deterioration and spalling. Ideal for both new and old concrete surfaces for exterior or interior exposures. This epoxy concrete sealer is also used as primer sealant for epoxy and polyurethane top coats.
