Polyurethane HD Aliphatic Polyurethane 2K Floor Coating | Low Temp 40 °F | Non-Yellowing

COVERAGE RATE

CURE SCHEDULE

Temperature and humidity directly affect pot life and dry time. Conditions should be between 40 – 95 °F (5 – 35 °C) and humidity should not exceed 80%.

MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: The recommended storage temperature is approximately 22 °C (72 °F). Do not damage containers. Store in a dry place. Do not store for extended periods in direct sunlight. Protect containers from resin and moisture contamination.

SURFACE PREPARATION: Make sure all contamination such as dirt, oil, grease etc has been removed from surface that might impact adhesion.  Recommend for proper adhesion on bare concrete surfaces floor is roughed up, either a light mechanical grind or blast is preferred or an acid etch.

For an acid etch preparation we suggest our E760CE Muriatic Replacement as a safer alternative.

PRODUCT MIXING:

• Stir Part A for 2 minutes with Jiffy Mixer type drill mixer at slow speed (500 rpm) to fully disperse the product
• To Catalyze product (get it ready to use) pour Part B into Part A slowly and mix for 2-3 minutes
• Pour a portion of mixed Part A and B back into Part B can until full and mix well for 30 seconds, then pour back into the mixed Part A and B can.
• Allow product to stand for 5 minutes before applying.  Loosely cover mixed product  DO NOT RESEAL MIXED PRODUCT!
• Product may be reduced with clean water to achieve desired viscosity.  We recommend using distilled water
• Typical spray applications require a 5% to 10% reduction with water.  Do NOT exceed 15%.
• Do NOT reduce catalyzed product after 30 minutes
• IMPORTANT:  Mark time to establish pot life from when you start mixing A and B.  Pot life to 1.5 hours.
• Do NOT mix with other products or other containers of RainguardPro Polyurethane HD

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. REDUCTION (OPTIONAL)  REDUCTION // CLEAR Pour the contents of Part B into Part A. After mixing the components well (as described below) for approximately two (2) minutes, it may be reduced with water up to twenty percent (15%). Typical spray applications require a 5% to 10% reduction. Do not exceed 15%. REDUCTION // WHITE Pour the contents of Part B into Part A. After mixing the components well (as described below) for approximately two (2) minutes,

Use of an improper drill mixer can result in 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.  Most mixing problems described above can be traced back to using a paint mixer..  DO NOT HAND MIX as this approach can result in the same problems as using a paint mixer.

PRODUCT APPLICATION: IMPORTANT: Proper methods to protect from over spraying should be implemented. Atomized particles will adhere to most surfaces and are extremely difficult to remove.  Temperature and humidity directly affect pot life and dry time. Conditions should be between 40 – 95 °F (5 – 35 °C) and humidity should not exceed 80%.  Can apply using brush, roller or sprayer.

POT life/working times will start to be reduced as humidity increases to 65% and at/above 80% there will be a very noticeable and significant reduction.  Increases in temperature above 75°F will have a similar effect.  As temperatures drop below 75°F, cure times will increase the time required to wait between coats.

Smooth Surfaces RainguardPro® Polyurethane HD may be applied directly over most surfaces without primer. Apply a light coat at a thickness of 3 to 4 wet mils. Do not exceed 5 mils. Reduction may create optimal flow. Dry mils thickness is 1.5-2.  Ferrous metal surfaces require primer before application.  When rolling product, recommend 1/4″ nap lint free roller for smooth surfaces

Porous Surfaces Most porous surfaces should have a sealer or filler to adequately eliminate potential pinholes prior to applying RainguardPro® Polyurethane HD .

• For unpainted porous surfaces, use Micro-seal Water Repellent/Sealer prior to application of RainguardPro® Polyurethane HD
• Apply one coat of RainguardPro® Polyurethane HD (3-4 mils wet per coat) allowing 4 hours between coats or when coating is tack free (pressing thumb into surface and no thumbprint remains)
• Any runs should be brushed our rolled out immediately before drying
• When dry, thickness is 1.5 – 2 mils
• When rolling product, recommend 3/4″ nap lint free roller cover for porous and textured surfaces

*For heavy duty applications such as warehouse floors with forklift traffic, total DFT thickness should be 3-4 mils (2 coats)

RECOAT OR TOPCOATING: Multiple coats of this product are acceptable.  When recoating this product, it is advisable to apply the recoat before 24 hours passes. If the first coat has dried longer than 24-hours, abrade the surface to promote adhesion for the second coat.

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  

CLEANUP: Clean up promptly with mild soap and water before product cures. Dispose of according to local, state and federal regulations.

LIMITED WARRANTY: 10 Year Warranty – Apply 1 coat at 2 mils DFT+.  Fill out warranty pre-application at RainguardPro.com

PERSONAL PROTECTION: RainguardPro® Polyurethane HD is a zero-VOC coating. The volatile to evaporate will be water. No special clothing or respirators are required. Due to its total water-based formulation, the hazard of flammability is removed.

LIMITATIONS

• RainguardPro® Polyurethane HD should be tested on all substrates before complete application
• Do not apply in humidity above 80% or rain
• Horizontal surfaces coated with RainguardPro® Polyurethane HD become slippery when wet recommend an anti-slip additive
• Should not be applied in high wind, rain or when the ambient teperature is below 5 °C (40 °F).
• Certain porous surfaces may require sealer or block filler to allow the RainguardPro® Polyurethane HD to create a more desirable aplpication and maintain the integrity of the surface.  Test patch should be applied before the final application
• Do NOT overapply.  More is NOT better.  A heavier application can cause micro blistering and affect the finish
• When using white color RainguardPro® Polyurethane HD over previously painted surface, test first to confirm it will provide the hide needed in a one or two coat application.  Lighter colors will be easier to cover in one coat.
• Physical properties are typical values and not specifications.
