Applications & Uses
- Applications
- Uses
- Steel and concrete surfaces that require a coating.
- Corrosion protection of sheet piles.
- Corrosion protection of steel piles.
- Corrosion protection of reservoirs, lock gates and many other application.
- All applications where a coal tar epoxy would be used.
- Surface Preparation
Steel: All contaminants shall be removed from the steel surface to be coated. Remove oil, dust, and grease and other contaminants that could interfere with adhesion of the coating. Surfaces shall be free from projections, sharp edges, high points and filets must be ground smooth including all corners. For immersion service, prepare surfaces by grit blasting to a clean, near-white finish, SSPC-SP 10 or NACE No. 2. Appropriate angular grit shall be used to achieve a 2.0 to 4.0 mil (50 to 100 microns) anchor profile. For non-immersion service, prepare surfaces using SSPC - SP2 / SP3.
Concrete: Concrete must be cured 28 days at 77°F (25°C) and 50% relative humidity. All surfaces shall me prepared in accordance with ASTM D4258 and ASTM D4259. All voids in concrete shall be filled and repaired.
- Application
Spray: A single-leg, airless unit shall be used. The unit shall be a minimum of 68:1 airless pump. A wet-on-wet spray technique should be used to achieve 16 to 26 mils (406 to 660 microns). The coating thickness should be measured using a wet-film thickness gage.
Brush: Use a medium bristle brush.
Roller: Use a short-nap roller cover with phenolic core.
For complete application instructions please refer to Protal 650 CTR Application Specifications.
- Cleaning
Clean equipment with MEK, Archco 400E™ Thinner or equivalent solvent cleaner.
- Mixing
Power mix both A & B separately then combine and power mix thoroughly for two minutes. Do not mix partial kits.
