MIXING AND APPLICATION INSTRUCTIONS

RODUCT 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.

INSPECTION:  Concrete must be clean, dry, and free of grease, paint, oil, dust, curing agents, or any foreign material that will prevent proper adhesion. The concrete should be at least 2500 psi and feel like 30-grit sandpaper. The concrete should be porous and be able to absorb water. A minimum of 28 days cured is required on all concrete. Relative humidity in the concrete floor slab should be below 80% (per ASTM F.-2170).

SURFACE PREPARATION: The most suitable surface preparation would be a fine brush blast (shot blast) or concrete diamond grind 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.  Want concrete prepared to a CSP 3 (feels like a 50 to 60 grit sandpaper)

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.

Calcium chloride tests can also be conducted to determine if the concrete is sufficiently dry for an epoxy flooring installation. The calcium chloride tests should be conducted in accordance with the latest edition of ASTM F 1869, Standard Test Method for Measuring Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride. When running a calcium chloride test, it is important to remove any grease, oil, curing agents, etc. so accurate readings can be obtained. A rate of 4.5lbs/1000 ft²/24hr period or less is an acceptable amount of vapor pressure for an epoxy flooring installation. If the reading is above 4.5lbs will require a moisture barrier system such as our P3 Industrial Liquid Moisture Vapor Barrier which can be applied to reduce the emissions.

Failing to adhere to these strict guidelines can result in product delamination, discoloration, blistering, or all together failure of the coating system. Testing is the responsibility of the applicator. Life Paint bears no responsibility for failures due to any of the above conditions.

PRODUCT MIXING:  This product has a mix ratio of two parts A to one part B by volume for standard colors (Example: to mix 3/4 gallon total NE3770 measure 1/2 gallon Part A and mix with 1/4 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 a chemically resistant Novolac Epoxy Mortar: Mix 2 to 5 parts of a 20-40 mesh kiln dried Silica Sand Aggregate, by volume, to 1 part of mixed NE3770 and mix until uniform in consistency.

READ CAREFULLY.  Improper Mixing May Result In Product Failure.  This Product Has a 2 To 1 Mix Ratio By Volume- Mix 2 parts by volume Of Part A With 1 part by volume Of Part B. ( Example: to mix 1 gallon total NE3770 to get started, measure 2/3 gallon Part A and mix with 1/3 gallon Part B).  Do not change the proportions and recommend do not mix more than you can use in 15 minutes.

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.

Mix part A (resin – color) separately in a container 4-6 minutes with a Jiffy Mixer first before combing parts A and B (hardener) together.  Clean mixing tool with solvent after mixing part A before mixing part B to prevent starting the chemical reaction and shortening cure time.  Only start mixing Parts A and B together when ready to start project.  Pour Part B into Part A while mixing at slow speed, 400-650 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.

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 NE3770 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.

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.

Pour the NE3770 out on the floor immediately after mixing and do not let the NE3770 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 material can be applied by brush or 1/4″ lint free professional grade epoxy roller cover. 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.  Depending on the look, thickness, chemical and abrasion resistance desired, 1 to 2 coats may be applied. A non-skid surface can be achieved by broadcasting and/or back rolling a washed and kiln dried aggregate into the coating.

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 (spiked) roller tool should be used prior to the coating tacking off to remove the air entrapped in the coating and help to release trapped air and minimize bubbles.

RECOAT OR TOPCOATING:

Although the E3770 recoat window typically opens in 4-5 hours at 75F, it Is Best To Test The Coating Before Recoating Or Topcoating. This Is Done By Pressing Your Thumb On The Coating To Ensure A Fingerprint Impression Is Not Visible. If There Is No Impression Visible, Then Coating The Floor Can Be Done. Note, Colder Temperatures Require Longer Cure Times Before Product Can Be Recoated. Prior To Coating The Floor, Make Sure There Are No Contaminants Exist. If Contaminants Or A Blush Exists, Remove With A Standard Detergent Cleaner And Ensure Floor Is Clean And Dry Prior To Coating.

Going past the re-coat window, typically 24 hours depending on temperature and humidity, means the NE3770 has become too hard and needs to be sanded with a 100 grit sanding tool to rough up the surface, wiped clean with acetone and then once the acetone has flashed off, you can apply the next coating.

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.
