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 4-5 minutes at same speed as outlined in step above
• Pour a portion of mixed Part A into B can until full .  Mix well for 30 seconds, then pour back into Part A. Mix for another 2-3 minutes.
• 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 for tinted white applications.  For clear applications do not exceed 10%.
• 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 1.5 – 2.0 hours.
• Do NOT mix with other products or other containers of MuralGuard Aliphatic Urethane

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.

WHAT COMES IN A KIT?

After mixing the components, may be reduced with water. Typical spray applications require a 5% to 10% reduction.

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.

Can spray apply with a low pressure airless or conventional sprayer.  Do not apply with a hand pump garden sprayer.  If product overapplied while spraying and runs down the surface, need to do a dry backroll to smooth out any runs or streaks before drying.

For airless sprayer recommend between a 3-12 fine tip (slower application and easier to control – good for beginners) to as large as a 5-17 spray tip (the 5=10″ fan pattern and the 17=.017 orifice opening for faster application recommended for experienced users wanting to spend less time).  Can also use a Graco FFLP tip (fine finish low pressure).  Use any airless sprayer (Pressure adjustment based on pump used and hose setup and tip size) or HVLP (high pressure low volume) sprayer.

Smooth Surfaces MuralGuard Aliphatic Urethane may be applied directly over most surfaces without primer. Apply a light coat at a thickness of 5 to 6  wet mils. Do not exceed 6 mils. Backroll any drips that occur.  Reduction may create optimal flow. Dry mils thickness is 2.5-3.  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 VandlGuard® IsoFree™ Aliphatic Urethane 2K.

• For unpainted porous surfaces, use Micro-seal Water Repellent/Sealer prior to application of MuralGuard Aliphatic Urethane
• Apply one coat of MuralGuard Aliphatic Urethane (5-6 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 2.5 – 3 mils
• When rolling product, recommend 3/4″ nap lint free roller cover for porous and textured surfaces

RECOAT OR TOPCOATING: Multiple coats of this product are acceptable.  When recoating this product with subsequent coats of the urethane, it is advisable to apply the recoat before 36 hours passes. If the first coat has dried longer than 36-hours, abrade the surface  to promote adhesion for the second coat.

CLEANUP: Clean up promptly with mild soap and water before product cures.  Once it cures it will be very difficult to remove.  Dispose of according to local, state and federal regulations.

GRAFFITI REMOVAL:  Use of commercially available solvents such as acetone (easiest for small graffiti removals with no rinsing required), lacquer thinner (must rinse after use), paint thinner (must rinse after use) or MEK* (no rinse required) are acceptable. Soak a rag or towel with the solvent and wipe the graffiti, rotating the rag to clean spots as it gets dirty to avoid redepositing the graffiti.

For larger graffiti removals, we recommend our VandlClean® Super Graffiti Remover and rinse with a pressure wash. This will allow for larger removals in a timely manner as the VandlClean Super will not flash dry like many solvents. Always use best practices when pressure washing to avoid damaging the substrate and/or paints and coatings.  Always do a test area to ensure your desired removal method is effective and not damaging the coating or substrate before proceeding.

*Only use MEK solvent in regions where it is allowed, there are many cities, counties or states that have strict laws on MEK use.

LIMITED WARRANTY: 10 Year Warranty – Apply 1 coat at 2.5 to 3.0 mils DFT+ and 15 Year Warranty for 2 coat application same mil thickness.  Fill out warranty pre-application at RainguardPro.com.  Warranty registration requires application by professional contractor.

PERSONAL PROTECTION:  MuralGuard Aliphatic Urethane 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

• MuralGuard Aliphatic Urethane  should be tested on all substrates before complete application
• Do not apply in humidity above 80% or if rain, snow or lower temperatures are expected within 48 hours.
• Do not apply on damp or moisture surfaces as it will whiten and may causes delamination
• Do not apply to surfaces if moisture content is greater than 25% as measure with an electronic moisture meter
• Horizontal surfaces coated with MuralGuard Aliphatic Urethane becomes slippery when wet
• Should not be applied in high wind, rain or when the ambient temperature is below 5 °C (40 °F) or above 100°F.
• Certain porous surfaces may require sealer or block filler to allow the MuralGuard Aliphatic Urethane to create a more desirable application 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 MuralGuard Aliphatic Urethane 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.
• If acid etch or acid stain has been applied to the surface, it must be thoroughly flushed to remove all residue and then allowed to dry.
• Protect shrubbery and other plants with a drop cloth.
• Protect automobiles, windows and metal not to be coated from overspray!  Remove any overspray as soon as possible.  Clean spills and leaks in a timely manner to prevent staining.
