150 Fast Cure 100% Solids Epoxy | Primer, Base Coat & MVB

One Stop Epoxy 150 Fast Cure (150FC) is a contractor grade, rapid-curing 100% solids epoxy engineered specifically for high-efficiency broadcast systems. This versatile resin functions as a primer, base coat, and Moisture Vapor Barrier (MVB) in a single application, allowing crews to complete full flake, quartz, and sand broadcast floors in a fraction of the time.

Designed for one day floor installations, 150FC performs exceptionally well in hot and humid environments, offering a rapid return to service without the "flash cure" risks of inferior fast-setting epoxies.

The 150FC Technical Advantage

• 3-in-1 System: Acts as a high-strength primer, pigmented base coat, and MVB rated up to 12 lbs.
• 90-Minute Recoat: Fast cure profile allows for scraping and top coating in as little as 90 minutes in warmer temperatures.
• Extended Working Time: Provides 20 to 30 minutes of open time on the floor nearly double that of traditional rapid cure epoxies.
• UV Considerations: Engineered for full broadcast systems (flake, quartz, sand) where the epoxy is fully covered to prevent visible ambering.

Best Uses for Fast Cure Epoxy

• One Day Flake Floors: The industry standard for rapid garage and commercial prep.
• Sand & Quartz Broadcasts: Ideal for industrial non-slip systems requiring fast turnaround.
• Humid Climates: Specifically formulated to remain manageable in high-humidity markets like Florida.

Mixing and Application (Critical for Success)

Pro Warning: 150FC is for experienced installers. It requires mechanical surface prep (CSP 2-3) and must be poured in ribbons immediately after mixing to avoid exotherm in the bucket.

• Mix Ratio: 2 Parts A to 1 Part B.
• Mix Time: 2 minutes if above 75°F; 3 minutes if below 75°F.
• Mixer: Use a box or cage style mixer for full kits.
• Working Time: 20–30 minutes depending on ambient temperature.

Frequently Asked Questions

Is this a good epoxy for garage floors?
Yes. It is the preferred base coat for professional installers performing one day full flake garage floor installations.

What makes 150FC different from other fast cure epoxies?
150FC includes a built-in moisture vapor barrier (up to 12 lbs) and offers significantly more working time on the floor than standard rapid-set resins.

Can I use this for a one day flake floor?
Yes. This is the primary use for 150FC. Its fast cure profile allows you to prep, base, flake, and topcoat in a single shift.

Why can’t this be used for solid color floors?
Because 150FC is a fast-cure aromatic epoxy, it will amber under UV exposure. It must be used in a broadcast system where it is completely covered by flakes, sand, or quartz.

Is this product beginner friendly?
No. 150FC is designed for experienced contractors who understand how to manage fast-curing materials and jobsite pacing.

Does this replace a moisture vapor barrier?
Yes. It is rated to block moisture vapor transmission up to 12 lbs, eliminating the need for a separate MVB primer step.

How long does 150FC take to dry before I can topcoat?
Depending on temperature and humidity, you can typically sweep, vacuum, and topcoat in as little as 90 minutes.

What is the working time for this fast cure epoxy?
Depending on temperature, you will have between 20 and 30 minutes of working time once the material is poured onto the floor.

Can 150FC be used outdoors?
Yes, provided it is part of a full broadcast system where the epoxy is entirely covered and protected from UV exposure.

Do I need to add solvent to thin this product?
No. This is a true 100% solids epoxy. Adding solvents will compromise the cure and the moisture vapor barrier rating.
