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.
-
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.
Technical Documents

One Stop Epoxys standard resin is a 2 to 1 ratio 100% solids, two-component, high-build epoxy floor coating that’s designed for applications where heavy-duty protection is required.
Our Epoxy is easy-to-use, self-leveling, and delivers a high-gloss and chemically resistant surface. Combine with Decorative Chips, quartz, or Metallic Additive systems to create an attractive and durable finish or broadcast non-slip aggregates to produce a non-slip surface.
Application Equipment:
Flat – 3/16 inch notched rubber squeegee Rollers
3/8” nap, woven, shed-resistant roller cover in 4, 9 , or 18 inch.
2 inch chip brush
Mixing: 100% Solids Self Leveling is a two-component coating and proper mixing is required.
Mix base thoroughly to disperse pigment before mixing with activator. (This is the time to add in your pigment)
Mix 2 parts base to 1 part activator by volume for two minutes, material is immediately ready for use after mixing base and activator; no induction time required. Do not mix more material than can be used within the working time.
Pot Life NONE – GET IT OUT OF THE BUCKET! Approximately working time is 30-45 minutes at 70°F and 50% relative humidity. Higher temperatures or humidity will shorten pot-life and working time.
Application Procedure:
Pour mixed material onto floor in a long bead approximately 12-18 inches wide. Do not drain or scrape remaining material in bucket.
Use either a flat or notched rubber squeegee and spread material to uniform thickness.
After material is spread, back-roll your material with a 3/8” shed-resistant woven roller cover.
Tips:
DO NOT BACKROLL MATERIAL AFTER IT BEGINS TO TACK-UP.
