a. Sandblast – best
Sandblast to a “commercial” (SSPC-SP6-63) or “Near White” (SSPC-SP10-63) blast finish. For best results, prime same day with PC-636 or MCU-100 Aluminum.b. Power Tool Clean
Follow instructions as outlined in SSPC-SP3 specification.
c. Hand Cleaning
2. Galvanized Steel
b. Old, Weathered or Rusty
3. Previously Painted Surfaces
All concrete should be prepared in accordance with the American Concrete Institute (ACI), Steel Structures Painting Council (SSPC) and National Association of Corrosion Engineers (NACE) concrete specifications. Remove all dirt, dust, oil, grease, laitance, efflorescence, loose or unsound concrete, and any chemical contaminants by such methods as high pressure water blast, wet or dry abrasive blast, vacuum shot blast, acid etching and other accepted surface preparation methods. A combination of these methods are normally used. Random pH readings using distilled water should be made to ensure all contaminants have been removed. A final pH reading of 7.0 – 8.5 is acceptable.
Coating System Concrete
|Mixing Instructions, Application Procedure & Recoat Time|
Stir each component to a uniform consistency, using an explosion proof variable speed drill with a Jiffy Mixer. Make sure any pigment settled to the bottom is incorporated. Do not vary proportions. PC-636 is prepared by mixing 4 parts Base (part A) to 1 part Hardener (Part B) with a power mixer. Allow an induction time of 15 minutes. PC-636 may be thinned up to 15% with SA-65 Thinner.Application Procedure
When spraying, use a 50% overlapping Crosshatch pattern to minimize the occurrence of pinholes. Do not apply to surfaces below 25 F or above 120 F. Do not apply over dew or frost. The surface temperature should be at least 5 F above the dew point.
|PC-636 is Flammable. Keep away from all sources of ignition during mixing, application and cure. The Hardener (Part B) is also corrosive and can cause eye and skin irritation 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 spraying coatings. Proper ventilation is always required.

PC-636 Low Temperature Curing High Build Epoxy Coating
Poly-Chem PC-636 is a high performing, surface tolerant, two component, high solids, high build amine cured epoxy designed to cure at temperatures down to 25 F. PC-636 Epoxy is specially modified with a proprietary blend of selective resins, wetting agents and penetrants to provide excellent adhesion and protection of sound, rusty steel surfaces. Depending on the temperature, the fast setting PC-636 can be recoated the same day.
