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: A suitable primer should be used before applying this product. See the front side of this technical data for primer information. If a primer is not used, more porous substrates may cause outgassing and possible surface defects.

PRODUCT MIXING:This product has a mix ratio of 9.1# part A to 4.25# part B or two parts A to one part B by volume for standard colors (Example: to mix 1 gallon total E707HB to get started, measure 2/3 gallon Part A and mix with 1/3 gallon Part B).  Do not change the proportions  Standard packages are in pre-measured kits and should be mixed as supplied in the kit.

For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer. Mix parts A and B separately by themselves in a container one to two minutes with a Jiffy Mixer first before combing parts A and B together.  Clean mixing tool with solvent after mixing part A before mixing part B to prevent starting the chemical reaction and shortening cure time.

Then pour Part B into Part A while mixing at slow speed, 650 rpm until a uniform blend is evident and streak Free.  Avoid Whipping Air Into The Coating during mixing.  Mix completely for approximately one to two minutes.  Mix only an amount that can be applied in the specified pot life time. Improper mixing may result in product failure. Be sure to work the bottom and edges of the bucket to ensure the entire contents of each part are mixed. The colored veins need to disappear. If the two components are not mixed completely the epoxy will not cross-link well and can develop curing problems that will lead to a substandard coating.  In E707HB that is colored, improper mixing can result in uneven color when pigment is not fully blended. It’s very important when mixing not to run the drill too fast or pump the mixing paddle up and down. Doing either of these this will introduce air into the mix which will be rolled into the coating and create air bubbles at the surface.

The epoxy should have a nice even consistency without any color streaks. Pour the E707HB out on the floor immediately after mixing and do not let the E707HB 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. 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. Always maintain a wet edge to avoid color shading differences.

RECOAT OR TOPCOATING: If you opt to recoat or topcoat this product, you must first 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. Some standard epoxy coatings and urethanes as well as multiple coats of this product are compatible for use as a topcoat. 7)

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

• 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.
• Because of the short pot life and dry time, attention should be given to the trim work and tie-in areas to keep a wet edge so as to avoid roller marks, differences in color or shading problems.
• 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.
• Light or bright colors may require a suitable primer or topcoat to achieve a satisfactory hide.
• Substrate temperature must be 5°F above dew point.
• All new concrete must be cured for at least 30 days.
• Apply a suitable primer before using this product.
• Physical properties are typical values and not specifications.
