ASTM D-4060: Abrasion Resistance

ASTM D-2794: Impact Resistance

ASTM D-3359: Adhesion

PREPARATION

  1. The concrete substrate to be coated must be clean, dry, and completely free of loose particles, grease, oil, or any substance that would interfere with proper bond.
  2. Surface and air temperatures must be at least 55°F during application. Surface and air temperatures should not exceed 90°F. Keep material from freezing.
  3. The surface-zone moisture content of the concrete should not exceed 4% wt. A test should be made to determine that the concrete has an appropriate vapor barrier. This can be done by placing a 4’X4’ plastic sheet on the substrate and taping down the edges. If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate does not show signs of eventual hydrostatic pressure problems that may later cause disbanding.
  4. For a one or two coat thin build system (3-10 mils dry) we recommend either mechanical scarification or acid etching until a suitable profile is achieved. For a complete system build higher than 10 mils dry, we recommend a fine brush blast (shot blast). If acid is used to clean the concrete, neutralize the surface completely and rinse it with water prior to application. Then wait for the concrete to dry out for at least 24-48 hours.

APPLICATION

Mixing:

This product has two components. The part A should be mixed with the part B thoroughly until uniform. The kits come prepackaged and should be used in their entirety and should not be broken down. If a color pack is used, it is recommended that the color pack be combined with the part A prior to adding the part B and then mixed well with the part B. After the two (or three, if color packs are used) parts are combined, mix extremely well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free. Avoid whipping air into the coating. Improper mixing may result in product failure. Once the material is opened, it cannot be re-sealed for later use.

Application:

Test the sealer in an inconspicuous area to ensure the desired coverage and appearance is achieved. Pour the mixed material into the application tray. Apply at the rate of 600 square feet per gallon in a uniform manner with a 3/8” nap roller. For uniform appearance, it is critical that the material is not applied thicker than this application rate. Dip the roller in the coating and roll out excess material in the roller tray prior to the actual application to the substrate. Overlap subsequent passes being sure no excess material is applied when overlapping. Make sure the floor has just enough material to cover evenly in a thin application. Finally, re-roll the area in the opposite direction of the first pass applications to level and even the application. The final re-rolling for the entire floor should be in the same direction. Remix the material in the application tray to maintain a uniform mix throughout the application process. If the appearance is not satisfactory, re-roll until the area is uniform in appearance. Maintain temperatures and humidity within the recommended ranges during the application and during the curing process. Make sure the substrate has a suitable epoxy primer that has been de-glossed (see surface preparation above) It is best to maintain a wet edge to avoid roller marks. Direct sunlight or high temperatures may cause visible roller marking during application. Too thick of an application may result in solvent entrapment and product failure. The surface must be dry before the application of this product.

NOTES

  • Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured. It is best to let the floor remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.
  • Some cleaners may affect the color of the floor installed. Test each cleaner in a small area, utilizing your cleaning technique. If no ill effects are noted, you can continue to clean with the product and process tested.
  • Colors or clarity for clear may be affected by high humidity, low temperatures, or chemical exposure
  • For best results use a high quality 3/8” nap roller.
  • Slab on grade requires moisture barrier.
  • Substrate temperature must be 5°F above dew point.
  • Relative humidity must be below 75°F.
  • All new concrete must be cured for at least 28 days.
  • Colors may vary from batch to batch, therefore, use only product from the same batch for an entire job.
  • Improper mixing or too thick of an application may result in product failure.
  • Light or bright colors (white, etc.) may require multiple coats or a suitable color coordinated primer to achieve a satisfactory hide.
  • Tire contact may cause discoloration or staining.
  • Material has to be applied at the recommended thickness per gallon uniformly for proper appearance and development of physical properties.
  • The epoxy primer must be abraded/de-glossed for proper adhesion.

Clean Up

Clean equipment, tools and surfaces with ketone solvent. Unused or old material may be disposed of in a waste disposal site in accordance with local, state and federal laws.

Precautions/Safety

Use appropriate safety equipment during application and handling. Please refer to the safety data sheet (SDS) for additional precautionary instructions before use.

Best Performance

  • Proper application is the responsibility of the user.
  • Make sure the most current versions of technical data sheets and safety data sheets are being used.
  • Keep out of reach of children and pets.
  • Store in a cool, dry place away from direct sunlight. Avoid opened containers, as moisture will cure the material.

Coverage

500 square feet per gallon. Variations in texture and porosity of substrate will affect the coverage and performance of the product.
