General
Application is critical to the success of high performance coatings. It is imperative that the proper choice of equipment be made, that the proper technique in using the equipment be followed, and also that the equipment be properly cleaned. B-2 Primer can be applied directly to most conventional coatings with no need for an intermediate coating. This allows the user to upgrade the chemical and solvent resistance of a surface with no fear of lifting or poor adhesion to old coatings. Induction Time: None required
Application
Drying Time (hrs.) 75°F to touch 0.75 to handle 4 to recoat 8 Pot Life 1-2 Limitations: Apply in good weather when air and surface temperatures are above 50°F. Provide adequate ventilitation to ensure thorough cure. Unmixed material (in closed containers) should be maintained in storage between 50° and 100°F. Keep from freezing.
Surface Preparation: Paint only clean, dry surfaces. Remove all grease, oil, dirt or other foreign matter by solvent or detergent washing.
Unpainted Surfaces: Prepare surface and prime with B-2 Primer. Apply one or more coats of B-2 Primer as required.
Concrete:
- "Brush-Blast Cleaning (SSPC-SP7) can be used to prepare the concrete by removing all foreign matter and provide tooth for bonding. Remove all dust from surface before starting the application of the coating. B-2 Primer is recommended to prime and seal concrete.
- “Water Blasting: Water Blasting equipment ,3500 psi tip pressure will remove laitance and provide suitable profile to assure good adhesion of B-2 Primer.
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). Sand or brush blast any glossy areas until dull. Spot prime bare areas as recommended and apply one or more coats of B-2 Primer 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 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.
Mixing: Material is supplied in 2 containers as a unit. Always mix a complete unit as supplied (3B to 1A). Thoroughly mix B Component before adding A Component. Combine entire contents of Part A and Part B and mix thoroughly with a Jiffy Mixer or equal for 2-3 minutes.
Thinning: Material is supplied at spray viscosity and normally needs no thinning. Thin only with amount necessary to obtain proper application and/or atomization (break-up) properties.
Application: Apply by conventional or airless spray. Thoroughly flush equipment with water. To obtain maximum edge protection and film build, conventional or airless spray is recommended. Application by other methods, brush or roll, may require more than one coat. Apply B-2 Primer at 4.0 mils wet which will yield 2.0 mils dry film thickness.
