CURE SCHEDULE

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.

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.

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%

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.

Dark Color Surfaces Applying lighter colors over existing dark colors may require addtional coats to “hide” the previous color and provide a uniform finish.

Smooth Surfaces RainguardPro® Whiteboard Dry Erase Paint 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® Whiteboard Dry Erase Paint .

• For unpainted porous surfaces, use Micro-seal Water Repellent/Sealer prior to application of RainguardPro® Whiteboard Dry Erase Paint
• Apply one coat of RainguardPro® Whiteboard Dry Erase Paint (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

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.

WARRANTY: RainguardPro® Whiteboard Dry Erase Paint will not yellow, crack, or peel over time.

PERSONAL PROTECTION: RainguardPro® Whiteboard Dry Erase Paint 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® Whiteboard Dry Erase Paint should be tested on all substrates before complete application
• Do not apply in humidity above 80% or rain
• Horizontal surfaces coated with RainguardPro® Whiteboard Dry Erase Paint become slippery when wet recommend an anti-slip additive when used on an horizontal surface
• Should not be applied in high wind, rain or when the ambient temperature is below 5 °C (40 °F).
• Certain porous surfaces may require sealer or block filler to allow the RainguardPro® Whiteboard Dry Erase Paint to create a more desirable application and maintain the integrity of the surface.
• Do NOT overapply.  More is NOT better.  A heavier application can cause micro blistering and affect the finish
• When using white color RainguardPro® Whiteboard Dry Erase Paint 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.

1. What is Whiteboard Paint Dry Erase?

Whiteboard Paint Dry Erase is a water‑based aliphatic polyurethane coating that transforms almost any smooth surface into a dry‑erase writable board. It’s low‑odor, zero VOC, UV‑resistant, and cures to a tough, durable surface suitable for schools, homes, offices or creative spaces.

2. What surfaces can I apply this dry erase coating on?

This coating can be applied on a variety of substrates including:

• Painted walls
• Chalkboards
• Plastic, glass, laminate
• Aluminum & metal
• Wood and more
  Properly prepared smooth surfaces will give the best write/erase performance.

3. How long until I can write on it after application?

You can write on the surface with dry‑erase markers 72 hours after application once it has fully cured.

4. How do I prepare my wall or surface before applying?

• Clean surface of dust, grease, or oils
• Smooth texture for best erase performance
• Sand lightly if necessary to create a consistent base
• Use primer or sealer on porous materials if needed

Proper surface prep prevents ink “ghosting” and improves adhesion. For unpainted porous surfaces, the use of Micro-Seal Water Repellent is recommended prior to Whiteboard Paint application.

5. What tools can I use to apply the dry erase paint?

The coating can be applied with:

• Brush
• Roller
• Airless sprayer

Mix parts A and B thoroughly as per instructions, and don’t exceed the recommended wet film thickness.

6. How do I clean and maintain the dry erase surface?

Use a microfiber cloth or soft eraser and mild cleaner. Avoid abrasive materials or harsh chemicals which can degrade the coating and cause micro scratches that trap ink.

7. Does whiteboard paint stain or ghost over time?

Like all dry‑erase surfaces, leaving marker ink on too long can lead to stains or ghosting. Regular cleaning and quality dry‑erase markers help prevent ink from settling into the surface.

8. Can I revert a dry‑erase coated wall back to a normal wall?

Yes — you can lightly sand the dry erase surface, prime it, and repaint with regular interior paint to make it a standard painted wall again.

9. Why choose water‑based polyurethane over epoxy or oil‑based coatings?

Water‑based polyurethane:

• Dries clear
• Has minimal odor
• Is easier to clean up
• Resists UV yellowing better than typical epoxy‑based dry erase coatings
  Oil‑based options are more durable in some environments but have stronger odors and longer cure times.

10. Can I use this paint outdoors or in humid areas?

This coating is designed primarily for interior use. High humidity, moisture, or exterior conditions can affect cure and performance if not properly protected. Always follow recommended temperature & humidity guidelines during application.
