MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Store product in an area so as to bring the material room temperature before using.  Continuous storage should be between 60 and 90 degree F.  Low temperatures or great temperature fluctuations may cause product crystallization.

SURFACE PREPARATION: The most suitable surface preparation would be a fine brush blast (shot blast) to remove all laitance and provide a suitable profile. All dirt, foreign contaminants, oil and laitance must be removed to assure a trouble free bond to the substrate. A test should be made to determine that the concrete is dry; 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 is dry enough to start coating. The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding.

PRODUCT MIXING: Each1.5 gallon kit of this product has a mix ratio of 1 gallon Part A to .5 gallon B by volume plus 15# aggregate. Standard packages are in pre-measured kits and should be mixed as supplied in the kit.  Before the two components are mixed together, mix the part A and part B separately to insure they are uniform before they are combined.  After the two parts are combined, mix well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free.  After the two liquid parts are combined, add in the provided aggregate and mix well with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and again streak free.   After mixing, transfer the mixed material to another pail (the transfer pail) and again remix. The material in the transfer pail is now ready to be applied on the primed substrate. This material has a high viscosity – mix well.

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.

Use of an improper drill mixer can result in streaking of the color because the pigment has not been thoroughly blended.  It can also create curing problems if the hardener also called activator (Part B) is not thoroughly blended with the resin (Part A) which can cause some areas on your floor to remain soft and not harden properly.  DO NOT USE A PAINT MIXER.  Many mixing problems described above can be traced back to using a paint mixer..  DO NOT HAND MIX as this approach can also result in the same problems as using a paint mixer.

PRIMING:  A suitable primer should be used before applying this product.  If a primer is not used, more porous substrates may cause outgassing and possible surface defects.

PRODUCT APPLICATION: The mixed material can be applied by a serrated squeegee at the recommended thickness, then backroll the applied liquids with an air release roller if necessary.  Finally, back roll (very lightly) with a conventional roller tool.  Maintain temperatures and relative humidity within the recommended ranges during the application and curing process.

RECOAT OR TOPCOATING:  Recoats or topcoats of this product are normally unnecessary.  However, if you opt to recoat or topcoat this product, you must first be sure that the coating has tacked off and then the surface should be deglossed to insure a trouble free bond prior to application of recoats or topcoats.  Always remember that colder temperatures will require more cure time for the product before recoating or topcoating can commence.  Before recoating or topcoating, check the coating to insure no epoxy blushes were developed (a whitish, greasy film, or deglossing.)  If a blush is present, it can be removed by any standard detergent cleaner prior to topcoating or recoating.  Multiple coats of this product are acceptable and can be used to achieve greater chemical resistance and build.

CLEANUP: Use xylol.

FLOOR CLEANING: Caution!  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.

RESTRICTIONS: Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure).  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.

LIMITATIONS:

• Color stability or gloss may be affected by environmental condtions such as high humidity, low temperature, or chemical exposure.
• Colors may vary from batch to batch.  Therefore, use only product from the same batch for an entire job.
• Apply a suitable primer before using this product.
• This product is not UV color stable and exposure to lighting (sodium vapor) can cause discolorations.
• Data based on neat resin without aggregate
• Mixtures of chemicals and applications with exposures to chemicals at elevated temperatures should be thoroughly evaluated before applying.  A test patch is recommended.
• Product can develop surface irregularities in leveling in combination to some chemical contamination or substrate compositions.
• Substrate temperature must be 5°F above dew point.
• All new concrete must be cured for at least 30 days prior to application.
• Results of use are contingent upon proper application.  Test patches are recommended.
• All new concrete must be cured for at least 30 days prior to application.
• Physical properties are typical values and not specifications.
