MIXING AND APPLICATION INSTRUCTIONS

1) PRODUCT STORAGE: Store product at normal room temperature. Continuous storage should be between 60 and 90 degree F.

2) SURFACE PREPARATION: Surface preparation will vary according to the type of complete system to be applied.  Make certain that the substrate where the E5820BL is to be applied is clean, sound and free of all laitance, dirt, dust, oil, grease, or foreign contaminants.  Make certain that the floor is completely dry before application.  It is often undesirable to shot blast a petroleum contaminated concrete surface unless the applicator is prepared to steam and solvent clean the area.  Shot blasting tends to open oil filled pores that will be detrimental to the application process.  The method of cleaning an oil soaked floor is best determined at the job location.  However, solvent cleaning, steam cleaning, and water emulsion cleaners can all be considered.  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.

3) PRODUCT MIXING: This product has a one to one mix ratio by volume- merely mix equal volumes such as 1 gallon of part A to 1 gallon of part B.  After the two parts are combined, mix well with slow speed mixing equipment such as a jiffy mixer until 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.

4) PRODUCT APPLICATION: We recommend one coat of E5820 followed by one coat of E5143/E5144 and then two additional coats of E5320/E5321 in the same color as the E5143/E5144.  Due to the vastly varying contamination parameters, it is recommended that the applicator both check the adhesion of this product to the substrate as well as a thorough evaluation of the proposed intermediate and topcoat selections.  Petroleum based oils have a tendency to migrate upward through newly placed coatings and could cause disbonding if all preceding coats are not inspected prior to topcoating.  Clean all previous coatings as necessary.  THIS COATING SHOULD NOT BE USED UNTIL A REPRESENTATIVE SAMPLE PATCH HAS BEEN PLACED AND THOROUGHLY EVALUATED FOR SUITABILITY.  Make certain that the floor temperature and air temperature is between 55 and 90 degrees Fahrenheit.  Preferably, the relative humidity should be below 90%.  This product should be applied by roller or brush at five to eight mil thickness when wet.  Too thick of an application may result in product failure.

5) RECOAT OR TOPCOATING:  After applying the NP820 and the coating has cured sufficiently, the applicator can then proceed with the NP143/144, NP321, application.  Allow sufficient time between all subsequent coatings; and remember, as temperatures become lower all products will require additional time to cure.  Read the individual technical data sheets for each product before proceeding.  If different topcoats are desired, contact your representative for application details before proceeding.

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  

6) CLEANUP: Use xylol.

7) 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.

8) 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.
