- Applications
- Typical Uses
- Mainly, but not limited to, applications for concrete floors, concrete or brick walls, suitable for any similar architectural or structural concrete structures.
- Performs on metal surfaces.
- Epoxytec 45 Primecoat™ is recommended for use on class 1, 2, 3, 4 concrete floors as classified in 1.1 of ACI Standard 302-69.
- Surface Preparation
- Coat only clean, dry surfaces.
- Remove all grease, oil, dirt or other foreign matter by solvent or detergent washing.
Concrete:
- Brush-Blast Cleaning (SSPC-SP7) can be used to prepare the concrete by removing all foreign matter and provide profile for bonding.
- Remove all dust from surface before starting the application of the coating.
- Epoxytec 45 Primecoat™ is recommended to prime and seal concrete.
Water Blasting:
- Water Blasting is acceptable in order to meet the standards described in NACE No. 6/SSPC-SP 13, “Surface Preparation of Concrete.”
Previously Painted Surfaces:
- Remove all rust, rust scale, other corrosion products, loose or heavy chalk and loose or scaling paint by: Hand or Power Tool Cleaning” (SSPC-SP-2 or 3).
- Brush blast any glossy areas until dull.
- Spot prime bare areas as recommended and apply one or more coats of Epoxytec 45 Primecoat™ as specified.
- Check compatibility by applying coating to a representative area and allow to cure and age.
- Then make cross-hatched cuts through the coating and check adhesion by firmly applying masking tape to the cross-hatched area and removing with a fast pull.
- If the coating remains intact and there is no wrinkling, lifting, blistering or any other sign of incompatibility present, coating work may then proceed.
- Application Method
- Epoxytec 45 Primecoat™ can be applied by brush, roller, or spray.
Mixing:
- Material is supplied in containers as a unit.
- The unit comes ready as supplied.
Thinning:
- Supplied at spray viscosity, requires no thinning.
Induction Time:
- Not applicable.
- To obtain maximum edge retention and film build, conventional or airless spray is recommended.
- Thoroughly flush equipment with solvent.
- Application by other methods, brush or roll, may require more than one coat.
Roller:
- Short nap roller cover.
Conventional Spray:
- DeVilbiss MBC-510 gun or equal; E-tip and 704 air cap; 3/8” ID material hose; double regulated pressure tank with oil and moisture separator.
Airless Spray:
- Minimum 28:1 ratio pump; .013” - .017” orifice tip; ¼” ID Teflon material hose; 90- 100 PSI line pressure.
- Limitations
- Apply in good weather when air and surface temperatures are between 50°F and 100°F.
- Keep from freezing.
- Coverage & Thickness
- Theoretical coverage will depend on substrate (how absorbent); however, product should be applied at 3 - 4 mils DFT (as thin as possible).
- The coverage will yield between 300 and 500 square feet per gallon depending on thickness.
