APPLICATION TEMPERATURE: 45-80 degrees F with relative humidity below 85%

MIXING AND APPLICATION INSTRUCTIONS

SUBSTRATE PREPARATION: The most suitable surface preparation would be a 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 moisture content is controlled to acceptable levels, 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 generally considered suitable for coatings. The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding. After surface preparation and before application, repair all bug holes and grind down any projections. Repair all cracks or concrete Imperfections. Surface should have a minimum tensile strength of at least 300 psi @ ASTM D-4541. Surface profile should be CSP 5 or greater per International Concrete Repair Institute guidelines.

PRODUCT STORAGE: Store product in an area as to bring the material to normal room temperature before using. Continuous storage should be between 60 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. It is very important to utilize a proper mixer and paddle to ensure a complete mix and to reduce the risk of introducing excessive air into the mixture. We recommend the use of a MAN-U-FAB M-61 (1 HP) mixer with a 10 gallon pail and TR4-10 mixing arm (www.mixall.com). With the mixer running, pour the part A into the mixing pail. Add the powder pigment bag to the part A liquid and mix for about 15 seconds. Add the part B liquids and mix again for another 15 seconds. Gradually, add all of the contents of the supplied filler part C into the liquid mixture and blend thoroughly until all particles are wetted out, normally about two minutes. Improper mixing may result in product failure. Make sure to apply the product immediately after it is completely mixed

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: Product should only be applied by trained persons experienced in polyurethane concrete flooring applications. To prevent lifting or delaminations, keyways (minimum 5/16″ wide x 5/16″ deep) must be cut at all terminations, joints, columns, doorways, and drains. It is very important to utilize a proper mixer and paddle to ensure a complete mix and to reduce the risk of introducing excessive air into the mixture. After mixing, spread the mixed material onto the floor at a thickness slightly greater than the desired finish, using a screed box or move the material by hand trowel. Trowel the surface lightly, using a steel finish trowel to smooth the surface. Finish trowel strokes should all be in the same direction. Do not over trowel or overwork the mortar. The material should be troweled to a finished thickness of at least 1/4″ to 3/8″. For thicknesses greater than 1″, add 25# of clean, dry 3/8″ pea gravel to the UNIT mixture to help reduce the heat generated during the cure. Immediately roll the surface lightly in no more than two passes with a mohair roller. Excessive rolling or use of a loop roller will reduce slip resistance. NOTE: Late or heavy rolling may induce pinholes. Lay abutting edges within 10 minutes to ensure a clean edge. A “wet edge” installation is imperative during large applications to avoid lines and ridges in the finished floor

Topcoat: Topcoats are optional dependent on desired results. In some areas, a suitable novolac or other types of coatings can be used, depending on specific 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.
