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.

Manufactured by Arizona Polymer Flooring (APF), part of ICP Group, it delivers physical strength, flexibility, chemical resistance, and heavy pigment loading in a single wall coating system. The result is a high gloss, seamless, easy to clean wall surface built for commercial, institutional, food processing, health care, pharmaceutical, biomedical, and animal care environments. Quick Answer: APF Epoxy 400 WC is a 100% solids, medium viscosity epoxy formulated specifically for vertical (wall) surfaces. It applies at 5 – 8 mils WFT per coat (approximately 200 – 320 square feet per gallon), typically requires 2 – 3 coats to reach the specified 12 – 20 mils installed dry film thickness, has a 25 minute pot life at 77°F, and reaches full cure in 7 days. Standard colors: White, Bone, Delta Fog, and Sterling. No separate primer is required — the first coat serves as the primer. Do not confuse this product with standard APF Epoxy 400, which is formulated for floors. Where Epoxy 400 WC Fits in Your System Epoxy 400 WC is the pigmented epoxy coating layer in a seamless wall system. It is applied directly to properly prepared concrete, masonry, or finished drywall. No separate primer product is required. The first coat of Epoxy 400 WC serves as the primer, with additional coats applied to build the specified film thickness and produce a pore free finish. Fiberglass reinforcement can be incorporated between coats when the wall system requires additional strength or crack bridging capability. A variety of APF compatible topcoats can be applied over Epoxy 400 WC depending on the environment and the performance requirements of the finished wall. Key Features and Benefits 100% solids epoxy: No solvent evaporation. Applied film thickness equals installed dry film thickness. Medium viscosity: Improved flow and handling at lower temperatures, with excellent application qualities on vertical surfaces. High pigment loading: Excellent substrate hide and consistent color when roller applied. High gloss finish: Smooth, seamless wall surface that is easier to clean and maintain in service. Physical strength and flexibility: Shore D hardness of 78 combined with 11% ultimate elongation. Chemical resistance: Designed for commercial and institutional environments exposed to routine cleaning chemicals and service conditions. Contact APF Technical Service for a specific chemical resistance chart. Fiberglass compatible: Can be reinforced with fiberglass when a stronger wall system is required. Exceptional bond to concrete: Greater than 400 psi (ASTM D4541). At this bond strength, the concrete substrate fails before the epoxy to concrete bond does, indicating that the coating adheres more strongly than the concrete itself. Low VOC: Clear at 70 g/L and Pigmented at 79 g/L. Recommended Applications Biomedical facilities Pharmaceutical facilities Food and beverage processing areas Commercial kitchens Health care and institutional buildings Veterinary and animal care facilities Mixing Instructions Premix Part A and Part B separately for 3 minutes each before combining. Move the drill around the container to scrape the sidewalls and bottom. Combine Part A and Part B at a ratio of 2 parts A to 1 part B by volume. Mix the combined material for 3 minutes with a medium speed drill mixer and a suitable mixing paddle. Continue scraping the sidewalls and bottom during mixing to ensure both components are completely incorporated. Distribute the mixed material to the wall immediately after complete mixing. Only mix as much material as can be applied within the 25 minute pot life at 77°F. Contractor Tip: Plan each batch around the approximately 25 minute pot life at 77°F. Pot life becomes shorter at higher temperatures. Have rollers, trays, masking, wall sections, and additional installers ready before Parts A and B are combined. Size each batch so it can be rolled onto the wall before it begins to set. Material that has started to cure must not be rolled back into because overworking partially cured epoxy can create roller marks, uneven texture, and finish defects. Coverage and Cure Application Detail APF Epoxy 400 WC Mixing Ratio 2A : 1B by volume Wet Film Thickness Per Coat 5 – 8 mils Coverage Per Coat Approximately 200 – 320 square feet per gallon, depending on applied thickness Coverage Per 1.5 Gallon Unit Approximately 300 – 480 square feet per coat Coverage Per 15 Gallon Unit Approximately 3,000 – 4,800 square feet per coat Installed Dry Film Thickness 12 – 20 mils total, typically achieved in 2 – 3 coats Pot Life at 77°F Approximately 25 minutes Dry to Touch at 77°F Approximately 8 hours Recoat Time at 77°F Approximately 16 hours Full Cure at 77°F Approximately 7 days Ambient Application Conditions Ambient temperature must be at least 5°F above the dew point. High humidity or low temperatures will prolong cure time. Coverage varies with wall texture, surface porosity, substrate condition, roller loading, application technique, and material remaining in the mixing container and tools. Higher temperatures shorten pot life and cure times. Lower temperatures and higher humidity extend cure times. Surface Preparation All surfaces must be clean, dry, structurally sound, and free from oil, grease, dust, wax, loose paint, curing compounds, and other contamination before Epoxy 400 WC is applied. Concrete substrate requirements: Concrete must be cured for a minimum of 30 days. Minimum compressive strength of 3,000 psi. Prepare the surface mechanically to achieve a minimum ICRI/CSP 3 – 4 profile. Refer to ICRI Technical Guidelines 310 – 330 for surface preparation standards. Acid etching is not recommended and will void the manufacturer's warranty. Vacuum the prepared concrete surface to remove all dust before application. Previously coated surfaces: Existing coatings must be soundly adhered. Mechanically clean and abrade the existing surface to a uniformly gloss free, open texture before recoating. Masonry and drywall: Masonry: Remove surface projections, mortar spatter, and irregular areas by grinding, scraping, or other appropriate mechanical preparation. Drywall: Finish to a Level 4 or Level 5 finish before coating. Concrete moisture testing: It is the applicator's responsibility to test concrete moisture in accordance with ASTM F2170-19. If moisture is indicated in excess of 85%, apply the APF VaporSolve® system per its published technical data sheet before installing Epoxy 400 WC. Contact APF Technical Service for further guidance. Application Guidelines Confirm that the prepared surface is clean, dry, and free of dust before beginning application. Measure and confirm that ambient temperature and humidity conditions are at least 5°F above the dew point before mixing any material. Mix Part A and Part B according to the instructions above. Apply the material immediately after mixing. Working from a mixing bucket (5 gallon size recommended) or roller tray, apply by dip and roll using a quality 1/2 inch or 3/8 inch solvent resistant roller cover. Distribute the coating uniformly at 5 – 8 mils wet film thickness per coat. Maintain a wet edge as the wall is coated. Do not roll back into material that has begun to set. Apply the next coat within the 16 hour recoat window to build the specified 12 – 20 mils installed dry film thickness, typically in 2 – 3 coats. Ensure each coat is pore and pinhole free before the next coat or topcoat is applied. If the 16 hour recoat window is exceeded, abrade the surface with 80 – 100 grit abrasive until the finish is uniformly dull and gloss free. Remove all sanding dust before applying the next coat. Heater Warning: Do not use kerosene or propane forced air heating equipment during application or cure. Combustion byproducts can cause discoloration and finish defects in the applied coating. If supplemental heat is required, use only indirect fired or electric heating equipment. Handling and Safety Use only with adequate ventilation. An appropriate cartridge type respirator must be used during application in confined areas. Avoid contact with skin. Wear protective gloves and safety glasses.
