150 Fast Cure 100% Solids Epoxy for One Day Full Broadcast Floors One Stop Epoxy 150 Fast Cure, commonly called 150FC, is a rapid cure 100% solids epoxy built specifically for full broadcast flooring systems. It is designed for full flake, quartz, sand, and other approved broadcast floors where the wet epoxy is completely covered with decorative or functional media. 150FC can perform three jobs in one application: primer, pigmented receiver coat, and moisture vapor barrier rated up to 12 lbs. This allows experienced installers to mechanically prepare the concrete, apply one epoxy layer, complete the broadcast, and move toward the topcoat without installing a separate primer or moisture vapor barrier when slab conditions are within the published product limits. At 75 degrees Fahrenheit, 150FC provides approximately 25 minutes of working time on the floor. Under a full broadcast, it cures in approximately 2 hours at 75 degrees Fahrenheit and can cure in as little as approximately 75 to 90 minutes in very warm conditions. Free shipping to the 48 contiguous states, and most orders ship out the same or next business day. Quick Answer: 150FC is a fast cure 100% solids epoxy for experienced installers building full broadcast floors. It combines a primer, pigmented receiver coat, and moisture vapor barrier rated up to 12 lbs in one application. Working time is approximately 25 minutes at 75 degrees Fahrenheit, and full broadcast floors can be ready for scraping and topcoating in approximately 2 hours at 75 degrees Fahrenheit or faster in warmer conditions. NOT FOR BEGINNERS 150FC is designed for experienced epoxy installers who understand fast cure materials, crew coordination, mixing, placement, broadcast timing, and jobsite temperature. Once Part A and Part B are combined, the installation moves quickly. If you are learning how to install epoxy flooring, use a slower and more forgiving epoxy system. What 150FC Is Built to Do 150FC is not intended to be a general purpose epoxy. Its strength is combining fast cure, full broadcast capability, and moisture vapor protection into a single resin layer. Application How 150FC Is Used Full Flake Floors Used as the pigmented receiver coat before broadcasting vinyl flakes to rejection. This is one of the primary uses for 150FC. Quartz Broadcast Floors Used as the resin layer that receives a full quartz broadcast in commercial and decorative flooring systems. Sand Broadcast Floors Receives a full sand broadcast where texture, additional build, or another resinous flooring layer is required. Other Approved Broadcast Media May be used with approved broadcast aggregate such as aluminum oxide when the complete flooring system calls for it. Moisture Vapor Control Provides moisture vapor resistance up to the published 12 lb rating when slab conditions and installation requirements are within the product limits. For a complete flake package with epoxy, vinyl flakes, and topcoat already matched to the floor size, see our Full Flake Epoxy Flooring Systems. Where 150FC Should Not Be Used 150FC must be buried beneath a complete broadcast. It is not the correct epoxy when the base coat itself will remain visible. Application Use 150FC? Full Flake Broadcast Yes Full Quartz Broadcast Yes Full Sand Broadcast Yes Partial Flake Floor No Solid Color Floor No Metallic Epoxy Base Coat No Exposed Epoxy Finish No 150FC is not UV stable and will amber when exposed to light. In a true full broadcast system, the epoxy is completely covered by vinyl flakes, quartz, sand, or another approved media before the clear wear coat is installed. That keeps the epoxy itself from remaining visible. For solid color floors, partial flake floors, and other applications where the epoxy remains visible, use our Self Leveling 100% Solids Epoxy instead. Why 150FC Works for One Day Full Flake Floors A traditional epoxy installation may require separate primer, epoxy, broadcast, cure, and topcoat stages spread across multiple days. 150FC is designed to compress that sequence. Mechanically prepare the concrete. Apply 150FC as the primer, moisture vapor control layer, and pigmented receiver coat. Broadcast the vinyl flakes, quartz, or sand to rejection while the epoxy remains wet. Allow the fast cure epoxy to harden. Scrape and vacuum the cured broadcast surface. Apply the specified clear topcoat. When the floor, temperature, crew, and complete system are appropriate, this sequence allows experienced installers to complete many full broadcast floors in one day. Working Time Changes With Temperature 150FC is fast, but it provides meaningful working time after it is properly mixed and immediately placed onto the floor. Jobsite Temperature Approximate Floor Working Time Below 75 degrees Fahrenheit Approximately 25 to 30 minutes 75 degrees Fahrenheit Approximately 25 minutes 76 to 85 degrees Fahrenheit Approximately 22 to 25 minutes 85 to 90 degrees Fahrenheit Approximately 20 to 22 minutes Important: Working time begins becoming relevant only after the mixed epoxy is spread onto the floor. Do not use the published floor working time as permission to leave mixed 150FC sitting in the bucket. Higher temperatures shorten working time. Fast Cure and Topcoat Timing Under a full broadcast, 150FC cures in approximately 2 hours at 75 degrees Fahrenheit. At temperatures above approximately 90 degrees Fahrenheit, cure can occur in as little as approximately 75 minutes. Actual timing depends on material temperature, slab temperature, surrounding air temperature, humidity, film build, and jobsite conditions. Do not begin scraping or topcoating simply because a fixed amount of clock time has passed. Verify that the broadcast surface is hard enough for the next step. Built In Moisture Vapor Barrier Up to 12 lbs 150FC provides moisture vapor resistance up to 12 lbs within its published product limits. This can eliminate a separate moisture vapor barrier coat on qualifying full broadcast projects. The 12 lb rating does not eliminate the need to evaluate the concrete. Test the slab before installation and compare the result with the current product requirements. If moisture exceeds the 150FC limit or the slab presents another moisture condition outside its intended use, select a dedicated moisture vapor barrier from our Primers and Moisture Vapor Barriers. For help understanding slab moisture before coating, review our Moisture Testing Before Installing Epoxy Flooring Guide. Coverage Rates Coverage must match the role 150FC is performing in the flooring system. Do not stretch the epoxy farther simply to increase square foot coverage. Application Coverage Per Gallon Coverage Per 3 Gallon Kit Pigmented Full Flake Receiver Coat 133 to 150 square feet 399 to 450 square feet Primer on Porous Concrete 150 to 200 square feet 450 to 600 square feet Higher Build Approved Broadcast Application 100 to 135 square feet 300 to 405 square feet For most full flake receiver coat planning, use the 133 to 150 square foot per gallon range. The exact rate should match the complete system, concrete condition, required film build, and moisture requirements. Available Colors 150FC is currently available in the following options: Clear Black Light Gray Medium Gray Dark Gray White Tan For a full flake floor, select the appropriate pigmented receiver coat so any small gaps between flakes do not expose an unwanted background color. Concrete Preparation Fast cure epoxy does not compensate for poor concrete preparation. The slab must be clean, sound, mechanically opened, and ready to receive a high build resin. Remove existing coatings, curing compounds, sealers, adhesive, oil, grease, and other contaminants. Mechanically prepare concrete to approximately CSP 3. Vacuum the prepared floor thoroughly. Repair cracks, spalls, pits, and damaged concrete before coating. Test the slab for moisture before relying on the built in 12 lb moisture vapor rating. Contractor Tip: With 150FC, the entire job should be staged before mixing begins. Have the floor prepared, flakes or aggregate opened, squeegee and rollers ready, spiked shoes on, and the crew positioned before Part A and Part B are combined. Mixing 150FC 150FC uses a 2 parts Part A to 1 part Part B by volume mix ratio. Premix Part A. Thoroughly mix the pre-pigmented Base before adding the Activator. If separate pigment is being added, completely disperse it into Part A first. Add Part B. Pour the Activator directly into the center of the Base container. Avoid pouring Activator onto the sides of the Base container. Use the correct mixer. For a full 3 gallon kit, use only a Cage or Box style mixer. A paddle mixer does not move enough of this thick material through a full 3 gallon batch to ensure complete mixing. Mix according to material temperature. Mix for 2 full minutes at approximately 300 to 450 RPM when the material is above 75 degrees Fahrenheit. Mix for 3 full minutes when the material is below 75 degrees Fahrenheit. Partial batches. Measure exactly 2 parts Base to 1 part Activator by volume. A red paddle mixer may be used for partial batches. Mix only until the material is completely uniform. Smaller batches require less mixing time. Do not exceed 3 minutes. No induction time is required. Mix it and GET IT OUT OF THE BUCKET. Do not leave mixed 150FC sitting in the bucket. This fast cure 100% solids epoxy generates heat rapidly when the mixed material remains concentrated in mass. As soon as mixing is complete, immediately pour the epoxy onto the floor. Application Pour immediately. Pour mixed 150FC onto the prepared floor in long ribbons approximately 12 to 18 inches wide. Do not drain or scrape the bucket. Material remaining on the sides or bottom may not be mixed as completely as the main batch. Spread the epoxy. Use an appropriate notched rubber squeegee to spread the material at the required coverage rate. Roll and back roll. Use a quality 3/8 inch shed resistant epoxy roller cover to even the material and maintain consistent coverage. Do not continue back rolling after the epoxy begins to tack. Once 150FC starts to set, leave the material alone and continue the installation sequence. Broadcast immediately. Apply the vinyl flakes, quartz, sand, or approved aggregate while the epoxy is wet enough to completely receive the broadcast. Prepare for the topcoat. After the broadcast has cured sufficiently, scrape and vacuum the surface according to the flooring system requirements, then apply the specified topcoat. 150FC Technical Specifications Specification Published Value Product Type Fast cure two component 100% solids epoxy Solids by Volume 100% Mix Ratio 2 parts Part A to 1 part Part B by volume Mixed Kit Size 3 gallons Mixed Viscosity Approximately 900 cps Working Time at 75 Degrees Fahrenheit Approximately 25 minutes on the floor Full Broadcast Cure at 75 Degrees Fahrenheit Approximately 2 hours Full Broadcast Cure Above 90 Degrees Fahrenheit As little as approximately 75 minutes Recoat Window Approximately 4 to 24 hours when an additional resin coat is required Heavy Foot Traffic Approximately 48 hours Vehicle Traffic Approximately 72 hours Moisture Vapor Rating Up to 12 lbs within published product limits Shore D Hardness 89 to 91 Compressive Strength 16,500 psi Adhesion to Concrete 600 psi Tensile Strength 3,550 psi Flexural Modulus 4,700 psi Koenig Hardness 145 Taber Abrasion 22 mg loss VOC Less than 50 grams per liter Concrete Preparation Mechanical preparation to approximately CSP 3 Application Roller 3/8 inch shed resistant epoxy roller cover Topcoating a Full Broadcast Floor Once the 150FC receiver coat has cured and the full broadcast is ready, scrape the surface in multiple directions and vacuum thoroughly before topcoating.

Frequently Asked Questions What is 150 Fast Cure Epoxy used for? 150FC is designed for full broadcast flooring systems including full flake, quartz, sand, and other approved aggregate systems. It functions as the primer, receiver coat, and moisture vapor barrier within its published 12 lb moisture limit. Is 150FC good for one day garage floors? Yes. One day full flake garage floors are one of the primary applications for 150FC. The fast cure allows experienced crews to prepare the slab, apply the receiver coat, broadcast flakes, scrape, vacuum, and topcoat in the same day when jobsite conditions allow. Is 150FC beginner friendly? No. 150FC is intended for experienced epoxy installers. The faster cure requires good job planning, correct mixing, immediate placement, fast spreading, and controlled broadcast timing. How much working time does 150FC provide? Working time is approximately 25 minutes at 75 degrees Fahrenheit after the epoxy has been properly mixed and placed onto the floor. Cooler conditions generally provide more time. Higher temperatures shorten working time. How quickly can I topcoat a full flake floor? Under a full broadcast, 150FC cures in approximately 2 hours at 75 degrees Fahrenheit. In very warm conditions above approximately 90 degrees Fahrenheit, cure can occur in as little as approximately 75 minutes. Confirm that the broadcast is hard enough to scrape and vacuum before applying the topcoat. Does 150FC replace a moisture vapor barrier? 150FC can perform the moisture vapor barrier role on qualifying projects with moisture conditions within its published 12 lb limit. Test the concrete before installation. Slabs exceeding that limit or presenting other moisture conditions may require a dedicated moisture vapor barrier system. Can I use 150FC for a partial flake floor? No. A partial flake floor leaves a large portion of the epoxy exposed. 150FC is intended for full broadcast systems where the epoxy is completely buried beneath the broadcast media. Can I use 150FC for a solid color floor? No. Use a general purpose 100% solids epoxy such as One Stop Epoxy Self Leveling 100% Solids Epoxy when the epoxy itself will remain visible. Can I use 150FC as a metallic epoxy base coat? No. Use the appropriate slower curing pigmented epoxy base beneath a metallic flooring system. 150FC is reserved for full broadcast applications. Why does 150FC have to be completely covered? 150FC is not UV stable and can amber when exposed to light. Full flake, quartz, and sand broadcasts completely cover the epoxy before the clear topcoat is installed, preventing the epoxy color from remaining visible. Can 150FC be used outside? It may be used only as part of an appropriate full broadcast system where the 150FC is completely buried and is not the exposed finish. The complete exterior system must use a suitable UV resistant topcoat. How do I mix a full 3 gallon kit? Use only a Cage or Box style mixer. Mix at approximately 300 to 450 RPM for 2 full minutes when the material is above 75 degrees Fahrenheit and 3 full minutes when the material is below 75 degrees Fahrenheit. Then GET IT OUT OF THE BUCKET and onto the floor immediately. Can I add solvent to extend the working time? No. Do not add solvent to 150FC. Altering the formulation can affect cure, film build, and moisture vapor performance. How much 150FC do I need for a full flake floor? A typical pigmented full flake receiver coat is applied at approximately 133 to 150 square feet per gallon, giving approximately 399 to 450 square feet from one 3 gallon kit. Actual material requirements depend on the concrete profile, porosity, repairs, film build, and normal application loss.

Recommended System Setup For a guaranteed bond and long term finish, follow this professional stack: Primer: LAB Surface Epoxy Primer (recommended for high traffic) or LABPOX 35 (self priming). Base/Body: Apply LABPOX 35 (Colored). Topcoat: Seal with LABFAST, LABSHIELD ECO, or AQUALAB PUR for additional UV and chemical protection. Mixing and Application Requirements Application Equipment 1/8 inch notched rubber squeegee 3/8 inch nap woven shed resistant roller cover 3 inch chip brush Mixing Instructions Precision in the mixing process is critical to ensure the chemical bond and structural integrity of the LABPOX 35 system. Pre-Mix Part A: Before final mixing, pre-mix Part A at low speed using a Paddle Mixer and a drill. Mixing should be done until the settlement comes off the bottom of the bucket and the color become uniform. Combine Components: Pour 2 containers of Part A (Base) into a large mixing bucket, being careful not to pour material onto the sides of the larger bucket. Add Activator: Pour the Part B (Activator) directly into the center of the large bucket. Again, ensure no material gets on the sides of the Base bucket; failing to do so may leave unmixed resin that causes soft spots on your finished floor. Mixing Time: Mix full kits with a Box Mixer for 2 minutes. Use a low-speed drill (300 to 450 RPM) to minimize air entrapment. DO NOT attempt to mix a full kit of this product with a Paddle Mixer. The volume is insufficient for a thick, heavy duty epoxy such as this. Scrape Sides: During the mixing process, make sure to scrape the sides and bottom of the mixing container thoroughly so no unmixed material remains. Immediate Placement: Once the product is properly mixed, it needs to be immediately poured onto the floor. Leaving mixed material for too long in a mixing pail will create an exothermic reaction (rapid heat buildup), rendering the product unusable. Application Procedure Application Procedure Pour mixed material in a 20 foot long 12 inch wide ribbon Do not drain or scrape remaining material from the bucket onto the floor. Spread to uniform thickness with a notched squeegee and roll North South and back roll East West to achieve uniform coverage. Roller should be a 3/8 inch shed resistant epoxy roller cover. PRO TIP: If pinholes appear during application, allow sufficient time to go back and burst them by rolling back and forth or with another squeegee pass. For extremely porous slabs, sand and plug persistent pinholes with epoxy gel after the first coat has cured. Frequently Asked Questions Is LABPOX 35 good for oil contaminated floors?Yes. It is considered best in class for resistance to oil and other contaminants that typically cause fisheyes or adhesion failure in standard epoxies. Can this be used as a self priming coat?Yes. LABPOX 35 is self priming and specifically designed to penetrate porous concrete slabs to reduce outgassing. Is this product beginner friendly?While it offers a comfortable 45 minute working time, proper mechanical surface preparation (CSP 2) and moisture testing are strictly required for a professional grade installation. How do I handle very porous concrete?On very porous slabs, use a tight squeegee with no back roll for the first coat to properly seal the surface before applying the body coat. What is the mix ratio for LABPOX 35?It is a two component system with a precise mix ratio of 2 Parts A to 1 Part B (2A:1B) by volume. Does this epoxy amber or yellow?Like most 100 percent solids epoxies, it is not UV stable. For maximum UV protection and to slow yellowing, a topcoat like LABFAST or AQUALAB PUR is strongly recommended. How soon can I walk on the floor?The floor can typically accept foot traffic in 24 hours, but full chemical cure takes 7 days. Do not clean the surface with water or chemicals during the first week. Is this product safe for interior use?Yes. LABPOX 35 is 100 percent solids and VOC free, making it virtually odor free and suitable for interior manufacturing, commercial, or residential projects.
