E903TC Urethane Topcoat

CURE SCHEDULE

APPLICATION TEMPERATURE: 45-85 degrees F with relative humidity below 85%

MIXING AND APPLICATION INSTRUCTIONS

SUBSTRATE PREPARATION: For applications over the E903SL All dirt, debris, dust and foreign contaminants must be removed to assure a trouble free bond to the broadcasted slurry.

PRODUCT STORAGE: Store product in an area as to bring the material to normal room temperature before using. Continuous storage should be between 50 and 90 degrees F. Low temperatures may cause product crystallization. Do Not Freeze.

PRODUCT MIXING: This product is packaged in pre-measured kits. Use the entire kit – do not modify. Pour the part A into a five gallon mixing vessel and add one bag of the powder pigment to the part A and mix about 15 seconds using a 1/2″ drill and jiffy type mixing paddle. Next, add the part B and again mix for about 15 seconds. Finally, gradually add all of the contents from the provided aggregate filler bag into the liquid mixture and blend thoroughly until all particles are thoroughly wetted out; this will usually take about two minutes. Use slow speed mixing equipment to avoid adding air into the mix. 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 cured broadcasted slurry. Remix occasionally to prevent settling of aggregate. Improper mixing may result in product failure. Make sure to apply the product immediately after it is completely mixed.

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.

Product Application: Immediately after mixing, pour mixed material on the floor in ribbons. Using a flat squeegee, move the material uniformly across the surface. Roll and back-roll material using a 1/4″ nap roller to a uniform appearance. Do not over work.

Topcoat: In some areas, a suitable novolac or other types of UV resistant coatings can be used, depending on specific chemical resistance or UV stability requirements.

Cleanup For cleaning any application, equipment, water can be used. The urethane component container is best cleaned with a suitable solvent.

Floor Cleaning and Restrictions: 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.  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

• Color stability or gloss may be affected by high humidity, low temperature, chemical exposure or lighting such as sodium vapor lights.
• Product is not color or UV stable.
• Do not install on wet concrete.
• Floors should be sloped to drain to prevent standing water or chemicals and spills should be removed as soon as possible to prevent a slipping hazard.
• Proper mixing is important for product performance.
• High heat exposure may discolor the surface.
• Colors may vary from batch to batch. Therefore, use only product from the same batches for an entire job.
• Always apply a suitable test area to evaluate the product performance and suitability prior to undertaking the entire project. Samples are available upon request.
• Mixtures of chemicals and applications with exposures to chemicals at elevated temperatures should be thoroughly evaluated before applying.
• Substrate temperature must be 5°F above dew point.
• All new concrete must be cured for at least 15 days prior to application.
• Moisture vapor transmission should be less than 12 pounds or less per 1,000 sq. ft. over a 24 hour period as per ASTM E1907.
