MIXING AND APPLICATION INSTRUCTIONS

SUBSTRATE PREPARATION: It is recommended that the concrete be prepared by method of shot blasting. To assure a trouble free bond, all dust, oil, dirt, foreign contaminants and laitance must be removed. It is recommended to perform a moisture test 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. Once 24 hours has passed, and 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 disbonding. This test does not guarantee, however, that there may not be future hydrostatic pressure issues in the future.

PRODUCT STORAGE: Product must be stored in an area that will bring the product to room temperature prior to using. Continuous storage should be between 60 and 80 degree F. Keep from freezing.

PRODUCT MIXING: Each kit is pre-measured, do NOT mix partial kits, but only mix the entire kit at one time.   Mix each kit in the proper order.  Please note:  Medium Gray or Tile Red Pigment is pre-mixed into the aggregate which is shipped in a plastic pail.  Step 1. Mix Parts A and B by themselves for 1-2 minutes in an oversized mixing bucket, add the gallon of Part B, then add the gallon of Part A and mix thoroughly until streak free.  Step 2.  Slowly add the 35 lbs of Part C aggregate into the bucket with mixed Parts A and B and slowly mix with a slow speed Jiffy mixer. Mix the material for 2-3 minutes until it’s uniform in color and thoroughly mixed. For easier application, mix parts A and B together for 1 minute, add 16 oz water and then mix another 30 seconds before mixing aggregate into bucket.  The water makes the mix wetter and will allow for easier application. Improper mixing may result in product failure.

For best mixing results and proper blending of parts A and B, recommend a JIFFY MIXER style drill mixer.

Product Application: The only time it’s necessary to prime the substrate is if outgassing is occurring during the installation process. Stop the process and prime the concrete. Once the kit has been thoroughly mixed, pour the mixed material directly on to the concrete. Use a GUAGE RAKE, or notched trowel to level out the product ensuring the product is as level and even as possible. It is then recommended to finish rolling the product out using a LOOPED ROLLER. If the desire is to achieve a smooth, 1/8” system, then the installation is complete, however, the floor will not be UV stable, so it is recommended to apply a UV Stable top coat.

For best thermal shock and heat resistance and achieve a 3/16” broadcast system, allow the material to self-level for 5-10 minutes, then broadcast 20-40 mesh silica sand into the floor. Do not broadcast the silica directly into the floor, but broadcast it upward, in a fanning motion, until complete rejection (full broadcast to refusal). It is very important to make sure the silica is broadcasted as even as possible.  When adding silica sand, will then need to add a clear topcoat to fully encapsulate and cover the silica. Once the floor is cured, about 4 hours later, sweep the floor for any excess aggregate, this silica can be reused.

Do NOT overapply HyperCRETE more than the designed application rate of 36 sq’ for each 2 gallon kit.  Over application can result in solvent entrapment and a weakened coating.  To achieve a thicker application you CAN apply a 2nd coat of HyperCRETE after the 1st coat has cured, typically 4 hours when it is tack free.  Apply the 2nd coat of HyperCRETE using the same process as the 1st coat.

Topcoat: A topcoat is required to encapsulate the silica if it is broadcast into the HyperCRETE.  If silica aggregate is not broadcasted into the HyperCRETE slurry system, then a top coat is not necessary. Depending on the type of facility the slurry system is being installed at will depend on which top coat to install. There are a variety of options, a high build epoxy, water based urethane (only use if no aggregate added to the HyperCRETE), Novolac, or 100% solids polyaspartic such as Aspartic 100 at a recommended coverage rate of 120-130 sq’/gallon or 2 coats of the Aspartic 85 at 160 sq’/gallon coat 1 and 200-250 sq’/gallon coat 2 (pigmented). For best decorative looking surface when doing a full aggregate broadcast, recommend mixing topcoat with pigment as the full broadcast tends to hide the HyperCRETE’s color.

Cleanup, Floor Cleaning and Restrictions: Use solvents for cleanup. When cleaning the floor, CAUTION! Some cleaners may affect the color of the installed floor. Test each cleaner used in a small area, ensuring no damage occurs. Restrict the use of the floor to light traffic and non-harsh chemicals until the floor is fully cured, refer to the cure schedule. Allow the floor to remain completely dry during the curing process.

LIMITATIONS

• Not Light Stable
• For best results use a gauge rake and looped roller
• Slab on grade requires moisture barrier
• Substrate temperature must be 5°F above dew point
• All new concrete must be cured for at least 30 days
• Physical properties are typical values and not specifications
• Do not allow product to freeze
• Do not mix partial kits, always mix the entire kit
• Make sure any repair work is fully cured before applying over it
• After 7 full days of curing will full chemical resistance be achieved
• Colors may vary from batch to batch, therefore use only product from the same batch for an entire job
