|Best Method is an abrasive blast (SSPC-SP6, or better), but PC-517 will perform well over minimally prepared surfaces. Because of the lack of “standards” for minimal surface preparation, test applications should be made to determine adequate surface cleanliness and compatibility with existing paint.
A. Steel: Remove oil, grease and other chemical contaminants by solvent wipe or steam cleaning. Abrasive blast to SSPC-SP6, or better.
B. Galvanized Steel: Solvent clean per SSPC-SP1 or steam clean. Apply VE-180 Vinyl Wash Etch Primer/Conditioner or abrasive sweep blast to achieve a profile.
C. Previously Painted Surfaces: Solvent clean per SSPC-SP1. Remove loose existing paint by wire brush or other hand tools. Feather edges. Make test application to check for compatibility.
D. Concrete: Do not use form release agents, surface hardeners or curing compounds.
All laitance efflorescence, chemical contaminants, grease, oil and other foreign material must be removed. The prepared surface must be clean and structurally sound. Methods such as abrasive blast, high pressure water blast, Blastrac, scarifying, scrabbling, acid etch/rinse, etc. can be used. Voids, spalled areas, and other defects should be grouted with Poly-Crete epoxy grout formula, then rubbed smooth before proceeding.
After concrete surface preparation is completed, prime the area with Prime-Crete PC-149 or PC-155 Concrete Primer per label instructions.
E. Epoxy Mortars: Surface to be coated should be free of all contamination. Observe the manufacturer’s recoat time recommendations.
|Mixing Instructions, Application Procedure & Cure Time|
Stir each component to a uniform consistency using an explosion proof variable speed drill with a Jiffy mixer. Then mix 4 parts Base A with 1 part Hardener B for 3 minutes using the powered Jiffy mixer. PC- 517 may be reduced up to 20% S-74 per mixed gallon. Do not substitute reducers.Application Procedure
1. Airless Spray
Gun – Graco – 205-591
Tip Range. – 0.019″-0.025″ at 2500 PSI
Hose – 1/2″ ID
2. Conventional Spray
3. Brush – use pure bristle brush
4. Roller – medium nap solvent resistant phenolic core
When spraying, use a 50% overlapping Crosshatch pattern to minimize the occurrence of pinholes. Do not apply to surfaces below 50 F. or above 120 F. Do not apply over dew or frost. Do not apply if the temperature is within 5 of the Dew Point.
|PC-517 Base is flammable. PC-517 Hardener is corrosive. 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 burns as well as allergic reactions. The use of goggles, fresh air masks or NOISH approved respirators, protective skin cream and protective clothing is a recommended standard practice when spraying 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-517 Poly-Chemcure Glass Filled Epoxy Mastic Coating
A two component, very high solids, high build, glass filled, Epoxy Mastic. PC-517 is based on a cycloaliphatic polyamine cured Epoxy. PC-517 Epoxy can be used as a One Coat-20 mil dry film Epoxy Ion horizontal surfaces. This unique coating has excellent chemical, abrasion, impact, and weather resistance with outstanding adhesion to marginally prepared surfaces as well as clean blasted surfaces.
