BondMaxx 128 Oil Stop Primer

BondMaxx 128 Oil Stop Primer is a two-component, solvent-based epoxy primer designed for properly prepared concrete surfaces affected by petroleum-based oil contamination. It is built to penetrate into the concrete surface, helping create a strong bond where standard primers may struggle. This primer is best suited for garages, workshops, automotive service bays, maintenance areas, mechanical rooms, warehouses, and industrial floors where petroleum-based oils may be present. BondMaxx 128 is supplied in black only and can be used as the first coat before applying a suitable epoxy, urethane, or polyaspartic flooring system. Why Use BondMaxx 128? Oil contamination is one of the biggest reasons floor coatings fail. Even after cleaning, petroleum oils can remain deep in the pores of the concrete and interfere with adhesion. BondMaxx 128 is designed to help overcome that issue by penetrating the substrate and creating a suitable primer layer for the next coating stage. Key Benefits Designed for petroleum oil-contaminated concrete Excellent concrete penetration Helps improve adhesion over difficult substrates Two-component solvent-based epoxy Suitable primer before compatible epoxy or topcoat systems Satin gloss finish 1:1 mix ratio by volume Black only Coverage: approximately 200–320 sq ft per gallon Recoat window: approximately 4–8 hours at 70°F Light foot traffic: approximately 16–24 hours Full cure: approximately 2–7 days Recommended Uses Automotive service areas Garages and workshops Maintenance bays Mechanical rooms Industrial floors Warehouse floors Concrete areas exposed to petroleum-based oils Important Limitations A representative test patch should always be applied and evaluated before proceeding with the full installation. Petroleum oils can continue to migrate upward through newly applied coatings, so adhesion and compatibility should be checked before applying additional coats. Application Overview Apply BondMaxx 128 by brush or roller at approximately 5–8 mils wet film thickness. For best results, use a high-quality 3/8" nap roller. The floor and air temperature should be between 55°F and 90°F, and the substrate temperature must be at least 5°F above dew point. The concrete should be clean, sound, dry, and free from loose contamination. Oil-contaminated concrete should be cleaned using an appropriate method for the site conditions, such as steam cleaning, solvent cleaning, or water-emulsion cleaning. Always confirm the surface is dry before coating. System Recommendation BondMaxx 128 is used as the primer layer. Once cured sufficiently, it can be topcoated with a suitable intermediate coat and finish coat, depending on the required floor system. For heavy-use areas, we recommend pairing it with a compatible Dymond epoxy base coat and a durable CrystalCoat topcoat.
