MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 60 and 90 degree F. Keep from freezing.

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.

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

PRODUCT MIXING:

This product has a mix ratio of 9.2# part A to 8.2# part B or one part A to one part B by volume.  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.  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.

The epoxy should have a nice even consistency without any color streaks. Pour the E139FL out on the floor immediately after mixing and do not let the E139FL sit in the bucket.  Leaving it in the bucket for as little as a minute or two can shorten the pot life by half or more.

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.  Because this material has a short pot life, it is beneficial in some applications to remove the material from the mixing pail by pouring the material onto the substrate and spreading it along the floor.  Spreading out the material will allow the applicator more time to work with the material before it begins to cure.  Aggregate should be broadcast into the applied material before applying suitable topcoats.

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. When using as a broadcast binder, always evaluate performance parameters with a test area which is dependent on aggregate size and thickness, prior to applicationve the air entrapped in the coating. Always maintain a wet edge to avoid color shading differences.

RECOAT OR TOPCOATING:   We recommend a suitable topcoat be applied only after broadcasting suitable aggregate into the basecoat.  If you recoat or topcoat this product, you must first be sure that the coating has tacked off before recoating.  All previous coats that were not applied as a broadcast, should be deglossed to insure a trouble free bond prior to application of recoats or topcoats.

It is advisable to test topcoats for suitability prior to application when not in a broadcast system.  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.

CLEANUP: Use xylol

SURFACE 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 surface to light duty and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the surface 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

• It is recommended that a broadcast application be performed with a subsequent topcoat system.  This product is not intended as a decorative coating, but merely as a flexible primer for bridging cracks in a broadcast system before topcoating.
• 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.
• Color or gloss may be affected by environmental conditions like humidity, temperatures, chemicals, or exposure to lighting such as sodium vapor lights.
• Colors 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 may discolor when exposed to UV lighting.  Otherwise the color stability of this product is good.  Therefore a topcoat is option and dependent on the environment.
• 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.
