BondMaxx 128 Oil Stop Primer

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 70Β°F
  • Light foot traffic: approximately 16–24 hours

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 55Β°F and 90Β°F, and the substrate temperature must be at least 5Β°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.

PRODUCT STORAGE: Store product at normal room temperature before using. Continuous storage should be between 60Β°F and 90Β°F.

SURFACE PREPARATION: Surface preparation will vary depending on the condition of the concrete and the full system being applied. The substrate must be clean, sound, dry, and free from loose contamination, laitance, dirt, dust, grease, or foreign materials. BondMaxx 128 is designed for petroleum-based oil contaminated concrete, but the surface should still be cleaned as thoroughly as possible before coating. Solvent cleaning, steam cleaning, and water-emulsion cleaners can all be considered depending on site conditions. Shot blasting oil-soaked concrete may open oil-filled pores, so the cleaning and preparation method should be evaluated on site. A test should be made to determine that the concrete is dry by placing a 4’ x 4’ plastic sheet on the substrate and taping down the edges. If after 24 hours the substrate is still dry below the plastic sheet, the concrete is dry enough to start coating.

PRODUCT MIXING: This product has a 1:1 mix ratio by volume. Mix equal volumes of Part A and Part B, such as 1 gallon of Part A with 1 gallon of Part B. After the two parts are combined, mix well with slow-speed mixing equipment, such as a jiffy mixer, until the material is fully mixed and streak free. Improper mixing may result in product failure.

PRODUCT APPLICATION: Apply BondMaxx 128 by roller or brush at approximately 5–8 mils wet film thickness. For best results, use a high-quality 3/8” nap roller. Make certain the floor temperature and air temperature are between 55Β°F and 90Β°F, and the substrate temperature is at least 5Β°F above dew point. Preferably, relative humidity should be below 90%. Do not apply too thick, as excessive thickness may result in product failure. Because petroleum oils can continue to migrate upward through newly applied coatings, a representative test patch should always be applied and thoroughly evaluated for suitability before coating the full area.

RECOAT OR TOPCOATING: After BondMaxx 128 has cured sufficiently, proceed with the selected compatible intermediate coat or topcoat system. Typical recoat or topcoat time is approximately 4–8 hours at 70Β°F. Colder temperatures will require additional cure time. Before topcoating, inspect the primer for adhesion, contamination, or oil migration. Clean previous coatings as necessary before applying the next coat. Always read the technical data sheet for each product being applied over BondMaxx 128 before proceeding.

CLEANUP: Use xylol.

FLOOR CLEANING: Some cleaners may affect the color or appearance of the installed floor system. Test each cleaner in a small area using your intended cleaning method. If no ill effects are noted, continue with the product and process tested.

RESTRICTIONS: Restrict the floor to light traffic and non-harsh chemicals until the coating system is fully cured. It is best to keep the floor dry throughout the full cure cycle. Depending on the complete system applied, the surface may be slippery, especially when wet or contaminated. Keep the surface clean and dry.

IMPORTANT LIMITATIONS: BondMaxx 128 is intended for petroleum-based oil contaminated concrete only. It is not intended for concrete contaminated with vegetable oil, animal fat, or synthetic oils. Always apply and evaluate a test patch before use to confirm suitability, adhesion, and compatibility with the full coating system.

Can This Be Installed Over My Existing Floor?

Yes, in many cases, but the floor underneath has to be clean, solid, and mechanically prepared. The coating can only bond as well as the surface it is applied to.

Every floor is different. When coating over anything other than properly prepared concrete, we strongly recommend applying a small test area first.

Bare Concrete

Best Surface

This system is designed to bond to properly prepared concrete. The concrete must be clean, dry, sound, and mechanically ground or shot blasted.

Existing Epoxy

Good With Prep

This system can be installed over an existing epoxy coating if the old coating is firmly bonded, clean, sound, and fully deglossed.

Tile

Conditional / Test First

Can be installed when tile is firmly bonded, clean, degreased, abraded, and tested first. Installation is done at your own risk.

VCT Tile

Conditional / Test First

Many customers successfully coat over VCT, but the bond depends on tile, adhesive, waxes, moisture, and movement. Installation is at your own risk.

Wood

Conditional / Scratch Coat

Requires a scratch coat first. Wood installations are done at your own risk. Always test first.

Required Surface Prep

For a strong bond, the surface must be mechanically prepared. Cleaning alone is not enough.

1

Grind or Shot Blast

The floor must be mechanically ground or shot blasted to create a surface profile the coating can grip.

2

Remove Contamination

Oil, grease, wax, soap residue, dust, old adhesive, sealers, and loose material must be removed before coating.

3

Repair Cracks & Defects

Cracks, holes, divots, and damaged areas should be filled before coating for a stronger, smoother finish.

4

Test First When Unsure

For tile, VCT, wood, unknown coatings, sealed floors, or questionable surfaces, apply a small test area.

Installation Questions We Get Every Week

Click any question to expand
? Does the floor need to be ground?

Yes. For a strong bond, the coating needs a clean, mechanically prepared surface profile.

? What does delamination mean?

Delamination is when the coating separates, peels, bubbles, or lifts from the floor underneath.

? Can this be installed over an existing epoxy?

Often yes, if the existing coating is fully bonded, clean, sound, abraded, and tested first.

? Can this be installed over VCT tile?

Sometimes, but the installation depends on the tile, adhesive, waxes, movement, and moisture. Test first.

? Can this be installed over wood?

Wood is conditional and normally needs a scratch coat. Always test first.

? Can this be installed over tile?

Tile can be conditional. It must be firmly bonded, cleaned, abraded, and tested before a full installation.

OK

Still Not Sure? Test Before You Coat.

Every floor is different. If you are coating over tile, VCT, wood, an unknown coating, sealed concrete, or a questionable surface, apply a small test area first before installing the full system.

The coating can only perform as well as the surface underneath it.
