Polyurethane HD Aliphatic Polyurethane 2K Floor Coating

RainguardPro® Polyurethane HD Aliphatic Poly Urethane 2K is a two-component, high performance, zero-VOC, odorless, water-based, aliphatic polyurethane paint/coating. Polyurethane HD provides years of excellent protection against harsh weather conditions, UV exposure, corrosion, physical damage, and has elastomeric properties. Polyurethane HD acts as a breatheable elastomeric waterproofer and can be applied in low temperature conditions down to  40 °F.

This product may be sprayed, brushed, or roller applied. Polyurethane HD is unique in that it has no VOC’s due to its total water-based formulation. When fully cured, this product has good chemical acid resistance, UV protection, excellent water resistance, abrasion resistance, flexibility, and is totally environmentally safe.

Polyurethane HD Aliphatic Polyurethane is a two component product and is packaged in 32 oz, 1 gallon and 4 gallon kits.  It is available with 3 gloss level options; matte, satin and high gloss finish and in a non-yellowing clear or in a pre-tinted white. It Has IsoFree Technology So That When Part B Is Mixed With Part A, The crosslink reaction makes the combined product free of any isocyanates.  Thereby the product is safe to apply for both the applicator and the environment with zero voc’s.

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. 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 25%.
  • 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 is 3/4 to 1 hour.
  • 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 (20%). Typical spray applications require a 5% to 10% reduction. Do not exceed 20%. REDUCTION // WHITE 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 eight percent (8%).  Typical spray applications require a 5% to 8% reduction. Do not exceed 8%

What comes in a kit?

Part A Part B Kit Makes*:
24 Fl. Oz. 2 Fl. Oz. 1 Quart
112 Fl. Oz. 4 Fl. Oz. 1 Gallon
448 Fl. Oz. 16 Fl. Oz. 4 Gallons

*See instructions for dilution percentages 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. 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 heavy 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. 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.
