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.

System Limitations Where to Upgrade: APF Epoxy 400 is a general purpose resin. It is not recommended for harsh chemical exposure, hot water wash downs, or food processing environments. Upgrade to APF Epoxy 600 or a Novolac system for those conditions. Common Frequently Asked Questions Can I use Epoxy 400 in a residential garage? Yes. APF Epoxy 400 works well as a base coat for full flake garage floors when applied to properly prepared concrete. What happens if I miss the 24 hour recoat window? You must sand the surface with 80 to 100 grit until it is gloss free before applying the next coat. How many pigment packs do I need for a 1.5 gallon kit? Use one pigment pack per unit. Larger kits are typically pre pigmented from the factory. Can Epoxy 400 be used for a metallic floor? It is not recommended. Metallic floors require a slower moving resin designed for pigment flow and pattern formation. Is Epoxy 400 UV stable? Standard epoxy resins can amber over time when exposed to UV light. APF Epoxy 400 is available in a UVR version for improved UV resistance. For areas with regular sunlight exposure, a UV stable topcoat should still be used. Why is mechanical grinding required? Grinding creates a consistent surface profile that allows the epoxy to bond properly. Acid etching does not achieve this. Can I hand mix this product? No. Epoxy 400 must be mechanically mixed with a slow speed drill and paddle mixer for 2 to 3 minutes. Hand mixing can lead to soft spots or uncured areas.

APF Epoxy 600 | High Performance 100% Solids Industrial Epoxy Product Overview APF Epoxy 600 is a high performance, low viscosity, 100% solids epoxy coating engineered for environments that demand superior chemical resistance and faster cure times than standard general purpose epoxies. It is a versatile system builder used as a high strength primer, durable finish coat, or aggregate binder. This modified epoxy chemistry provides stronger cross linking and improved resistance to acids, alkalis, and solvents. It is the ideal solution when service conditions are too aggressive for entry level epoxy, but do not yet require the extreme chemical load and cost of a full novolac system. The Performance Gap Solution: When a basic epoxy isn't tough enough, but a novolac would be overkill, APF Epoxy 600 provides the perfect balance of industrial durability and cost effectiveness. Where APF Epoxy 600 Fits in Your System High Strength Primer: Excellent low viscosity formula ensures deep substrate wetting and superior bond to prepared concrete. Industrial Finish Coat: Provides a durable protective top layer for manufacturing and high traffic warehouse environments. Aggregate Binder: Serves as a high strength resin for troweled mortars or broadcast quartz and chip systems. Intermediate Chemical Layer: Ideal for facilities needing enhanced resistance without stepping up to a specialized novolac. Substrate Limitations & Requirement for Specialty Primers While APF Epoxy 600 features exceptional adhesion properties, certain site conditions require the use of specialized primers to ensure long term system integrity. Utilizing Epoxy 600 as a standalone primer is not recommended under the following conditions: Specialty Primers are mandatory if the substrate exhibits: Moisture Vapor Emissions: Slabs with elevated MVE rates require a dedicated Moisture Vapor Barrier (MVB). Hydrocarbon Contamination: Oil soaked or grease contaminated concrete requires an Oil Stop Primer for a permanent bond. Compromised Surface Integrity: Weak, spalled, or dusty concrete requires a deep penetrating primer to stabilize the surface. Existing Coatings: Installations over previously coated surfaces often require a specialized tie-coat primer to prevent inter-coat adhesion failure. In these scenarios, the appropriate specialty primer must be applied first. APF Epoxy 600 should then be utilized as the high performance body coat and wear layer.

With a compressive strength of nearly 19,500 psi and a Shore D hardness of 82, it is engineered to withstand the heavy point loading and abrasive wear associated with frequent forklift and pallet jack traffic in manufacturing and warehouse settings. When should I use Epoxy 600 instead of standard epoxy? You should upgrade to APF Epoxy 600 when your project environment demands more chemical resistance and faster turnaround times than a general purpose epoxy can provide. It is the industrial step-up choice for professional results. Is Epoxy 600 resistant to hot tire pick up? Yes. Because Epoxy 600 is a high performance 100% solids resin with high cross-linking density, it does not soften under the heat of automotive tires. This makes it a superior choice for high end automotive shops and showrooms. Can I apply this over an existing epoxy coating? Generally, no. For Epoxy 600 to perform at its full industrial specification, it must bond directly to a mechanically profiled concrete surface. Applying a high performance industrial epoxy over a lower-grade, failing coating creates a weak link in the system. Why is the pot life only 20 minutes? High performance resins cure via an exothermic reaction. The faster cure time is a professional feature that allows for quicker turnaround, but it requires the installer to pour the material onto the floor immediately after mixing to avoid excessive heat buildup in the bucket. Does this product work in lower temperatures? Yes. APF Epoxy 600 cures much better in cool temperatures (down to 50°F) than most general purpose epoxies, making it a favorite for winter installations or cooler facility environments.

LABPOX MVB FAST | 100% Solids Epoxy Moisture Vapor Barrier LABPOX MVB FAST is a professional grade, 100% solids epoxy moisture vapor barrier designed to stop moisture before it destroys your floor. This system is engineered to bond to damp concrete slabs with up to 100 percent relative humidity, making it one of the most reliable solutions for moisture control in the industry. Moisture is the leading cause of epoxy floor failure. This product is designed to eliminate that risk and provide a stable foundation for epoxy, polyaspartic, and urethane flooring systems. If you are installing over a slab with unknown moisture conditions, this is not optional. This is your insurance policy. Performance and Moisture Control Up to 100% RH: Bonds directly to damp concrete and new concrete slabs less than 28 days old. Permeance: Less than 0.1 perm at 16 mils for maximum vapor protection. Moisture Reduction: Reduces emission rates from 25 lbs to less than 3 lbs per 1000 sq ft. Pinhole Mitigation Technology: Formulated to reduce surface defects and bubbles by up to 98 percent. Surface Preparation Requirements Proper preparation is mandatory. This product solves moisture problems, not surface contamination issues. Mechanical Preparation: Surface must be mechanically ground or shot blasted to a minimum CSP-2 or CSP-3 profile. Fiber Reinforced Concrete: All surface fibers must be completely removed by burning or grinding. Fibers act as conduits for moisture and will compromise the barrier if not fully encapsulated. Clean Surface: Concrete must be free of grease, oil, paint, or curing agents. Use a moisture meter to evaluate slab conditions. While this product bonds to high RH slabs, the surface must be free of standing moisture at the time of application. Radiant Heat: If a heated floor is installed, turn the system off 2 to 4 hours before application and keep it off for the duration of the cure. Mixing Instructions Proper mixing is critical to ensure the chemical properties of the moisture barrier activate correctly. Pre Mix Part A: Mix Part A at low speed before combining to ensure all pigments and solids are fully suspended. Mix Ratio: Combine 2 parts Part A with 1 part Part B in a clean container. Mix Time & Technique: Mix for 3 minutes using a Box Mixer and a low speed drill at 300 - 450 RPM. Immediate Placement: Once mixed, the material must be immediately poured onto the floor in ribbons. Leaving it in the pail will cause an exothermic reaction, making the product unusable. Application Apply using a 3/16 inch notch squeegee and back roll with an 18 inch roller to achieve a uniform film thickness. Work the material into the pores of the concrete to ensure full penetration. A minimum thickness of 16 to 18 mils is required to meet the permeance ratings for moisture mitigation. PRO TIP: This is a fast moving product. Once Part A and Part B are mixed, begin application immediately. Do not allow material to sit in the bucket. Extended dwell time will shorten working time and can lead to poor flow and inconsistent results. Coverage Rates and Permeance The vapor barrier performance of this product is directly proportional to the thickness of the coating. To ensure the permeance rating and performance of the barrier, Labsurface recommends a uniform film thickness of 16 to 18 mils. Thickness (Mils) Approx. Coverage 16 Mils (Recommended) 100 Sq. Ft. Per Gallon 14 Mils 114 Sq. Ft. Per Gallon 12 Mils 133 Sq. Ft. Per Gallon 4 to 6 Mils (Green Concrete Primer) 265 to 400 Sq. Ft. Per Gallon Frequently Asked Questions Can I broadcast vinyl flakes or other aggregates directly into MVB FAST?No. Broadcasting flakes or other aggregates directly into the moisture vapor barrier will decrease the moisture vapor resistance by as much as 75 percent. MVB FAST is a dedicated mitigation layer and must be applied as a standalone film at a uniform thickness to maintain its perm rating. You must apply a separate receiver coat over the barrier before broadcasting flakes. Do I really need a moisture vapor barrier?If you are unsure of the moisture levels in your slab, the answer is yes. Moisture is the leading cause of coating failure. Using MVB FAST is your insurance policy against delamination. Can this be applied to damp concrete?Yes. This product is designed to bond to concrete slabs with up to 100 percent relative humidity, provided the slab is completely dry to the touch at the time of installation. What happens if I have fiber reinforced concrete?Fibers can act as conduits for moisture to travel through your coating. You must burn or grind away all surface fibers and ensure a minimum 16 mil thickness to fully encapsulate them. How fast can I continue my flooring system?MVB FAST is engineered for speed. You can typically recoat in as little as 3 to 4 hours, allowing you to install a full system in a single day. What causes fisheyes or bubbling in the vapor barrier?Most issues are caused by surface contaminants or air movement. Ensure all HVAC vents are directed away from the floor and turn off all fans to prevent the material from skinning over prematurely. Can I use this over new concrete?Yes. This product can be applied to new concrete slabs that have been installed within 28 days, provided the surface humidity is controlled for at least three hours prior to installation. Why is reverse mixing recommended?Switching your mixer to reverse mode after 90 seconds forces the liquid from the bottom of the can to the top. This ensures a 100 percent homogeneous mixture which is critical for moisture mitigation. What is the maximum moisture reduction rate?When applied at the correct thickness, it reduces moisture emission rates from 25 lbs down to less than 3 lbs per 1000 square feet over 24 hours. Do I have to sand before applying my next coat?If you apply the next layer within the 24 hour recoat window, no sanding is required. After 24 hours, you must sand the surface to a dull finish to ensure a mechanical bond. Does this stop hydrostatic pressure?Very high levels of humidity may indicate hydrostatic pressure from a drainage failure or water leak. While MVB FAST is a powerful barrier, the source of any major water leaks should be addressed before installation.
