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: This product has a mix ratio of 1 part A to 2 parts B by volume for standard colors. Standard packages are in pre-measured kits and should be mixed as supplied in the kit. We highly recommend that the kits not be broken down unless suitable weighing equipment is available. 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 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 substrate. Improper mixing may result in product failure. This material has a high viscosity – mix well.

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 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.  Most mixing problems described above can be traced back to using a paint mixer..  DO NOT HAND MIX as this approach can result in the same problems as using a paint mixer.

****IMPORTANT NOTE AFTER MIXING:****

Once parts A&B are thoroughly mixed, immediately pour 100% of all mixed product on the floor in a ribbon pattern, S or W shape over the area you want that amount of product to cover. The risk of leaving product in the bucket is that it will become hard and reduce the working time by a minimum of 50% and may harden and start smoking in the bucket before you get back to it.

PRIMING:  Primers may be beneficial in some applications, dependent on performance characteristics and substrate conditions, but none are required for product application.

PRODUCT APPLICATION: The mixed material can be applied by brush or roller. However, the material can also be applied by a suitable serrated squeegee and then back rolled as long as the appropriate thickness recommendations are maintained. Maintain temperatures and relative humidity within the recommended ranges during the application and curing process. If concrete conditions or over aggressive mixing causes air entrapment, then an air release roller tool should be used prior to the coating tacking off to remove the air entrapped in the coating.

RECOAT OR TOPCOATING: If you opt to recoat or topcoat this product, you must be sure that the coating has tacked off before recoating. However, all previous coats should be deglossed to insure a trouble free bond prior to application of recoats or topcoats. Colder temperatures will require more cure time for the product before recoating or topcoating can commence. Before recoating or topcoating, check for epoxy blushes (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. Many epoxy coatings and urethanes as well as multiple coats of this product are compatible for use as a topcoat. 7)

Refer to the cure schedule as a guideline to follow, in addition we strongly recommend to test the coating before recoating or topcoating. This is done by pressing your thumb on the coating in multiple places to ensure a fingerprint impression is not visible. If there is no impression visible, then coating the floor can be done. Note, colder or hotter than 75 degrees can affect the curing time schedule  

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: 

• Clarity of color or gloss may be affected by environmental conditions such as high humidity, low temperatures, or chemical exposure.
• Clarity of color may vary from batch to batch. Therefore use only product from the same batch for an entire job.
• This product is not UV color stable and exposure to lighting such as sodium vapor lights may cause product discolorations.
• This product is not intended as a decorative coating, but merely as a primer or sealer for bridging cracks.
• Substrate temperature must be 5°F above dew point
• All new concrete must be cured for at least 30 days prior to application.
• Physical properties are typical values and not specifications.
