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.

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.

Technical Performance Snapshot Physical Property Value Mix Ratio 2 Parts A to 1 Part B Compressive Strength 19,480 psi Tensile Strength 8,590 psi Shore D Hardness 82 VOC Content < 50 g/L (Low VOC) Cure Schedule Condition At 77°F (Standard) At 50°F (Cool) Pot Life 20 Minutes Increased Dry to Touch ~3 Hours ~18 Hours Recoat Window 12 to 24 Hours 18 to 24 Hours Full Cure ~7 Days ~14 Days Frequently Asked Questions How does Epoxy 600 handle forklift traffic? APF Epoxy 600 is specifically designed for industrial durability. 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.

APF Epoxy Novolac 900 | Chemical Resistant Novolac Epoxy APF Epoxy Novolac 900 is an industrial strength, 100% solids epoxy built for environments where standard epoxy breaks down under chemical exposure. If you are dealing with battery acid, concentrated chemicals, or aggressive industrial conditions, this is the type of system that should be considered. This is not a general purpose epoxy. It is used when chemical resistant flooring is required, not just a protective coating. Unlike standard floor coatings that can soften, stain, or lose adhesion when exposed to solvents or acids, Novolac 900 is engineered with a tighter molecular structure that helps prevent chemicals from penetrating the resin and reaching the concrete below. Technical Performance Snapshot Physical Property Value Mix Ratio 2 Parts A to 1 Part B Compressive Strength 12,500 psi Tensile Strength 8,200 psi Flexural Strength 10,200 psi Hardness 82 Shore D Bond Strength >350 psi, concrete failure VOC Content <50 g/L Important System Design: Novolac 900 is intended to serve as the chemical resistant surface in the system. Do not assume standard clear topcoats are suitable over this product. Many decorative topcoats do not offer the same chemical resistance as a novolac epoxy. Let the Novolac do the work unless a compatible system has been confirmed for the specific exposure. What Chemicals Can It Handle? APF Epoxy Novolac 900 is designed for harsh industrial exposure, including strong acids, solvents, and chemical storage areas. It is especially suited for applications involving inorganic acids, including 98% sulfuric acid. 98% sulfuric acid Battery acid and electrolyte exposure Chemical processing areas Solvent exposure Waste treatment environments Industrial chemical storage Actual chemical resistance depends on concentration, exposure time, temperature, cleaning procedures, and full system design. For critical applications, confirm chemical resistance requirements before installation. Cure Schedule Condition At 77°F At 40°F Pot Life ~30 Minutes Extended Dry to Touch ~4 Hours ~18 Hours Light Traffic ~10 Hours ~36 Hours Recoat Window 12 to 24 Hours 18 to 24 Hours Full Cure and Chemical Resistance ~7 Days ~14 Days Common Questions About Novolac Epoxy How is Novolac different from normal epoxy? Think of normal epoxy as a screen door and Novolac as a solid steel door. Chemicals can eventually soak into standard epoxy and cause softening, staining, or failure. Novolac has a much tighter structure that helps keep chemicals on the surface so they are less likely to damage the resin or the concrete underneath. Do I need a primer first? On most slabs, yes. A quality primer can help seal the concrete and reduce outgassing. For chemical exposure areas, the full system should be selected carefully so the primer, body coat, and final surface all match the exposure requirements. Can I add color flakes or metallic pigments to this? It is not recommended for serious chemical areas. Flakes and metallic pigments are decorative materials, and the chemicals that this floor is designed to resist may attack those decorative components even if the Novolac itself remains intact. For chemical service, solid color systems are usually the safer choice. Does Novolac smell bad during installation? APF Epoxy Novolac 900 is a 100% solids product with VOC content listed at less than 50 g/L. Proper ventilation and safety practices are still required, but it does not install like older solvent heavy industrial coatings. Is it harder to apply than regular epoxy? The application method is similar. Apply with a squeegee and back roll with a 3/8 inch nap roller. The difference is that chemical resistant systems are less forgiving. Mixing, surface preparation, coverage rate, and recoat timing must be handled correctly. Will it turn yellow in the sun? Like most epoxies, Novolac 900 can amber when exposed to UV light. It is best suited for interior industrial spaces where chemical resistance matters more than long term color stability. Can I use this for secondary containment? Yes. Novolac epoxy is commonly used in containment areas, pits, and chemical storage spaces where the coating system must help keep spills on the surface and away from the concrete below. Surface Preparation Concrete must be clean, sound, and mechanically prepared to a CSP 2 to 3 profile. Grinding or shot blasting is required to create the proper surface profile for adhesion. Acid etching is not considered a professional installation procedure and should not be used in place of mechanical grinding or shot blasting. It does not create a consistent surface profile and may void manufacturer warranties. After preparation, vacuum thoroughly to remove dust and debris. Mixing and Application Mix using a slow speed drill and paddle mixer for 2 to 3 minutes. Scrape the sides and bottom of the mixing container during mixing. Do not mix by hand, and do not whip air into the material. Apply immediately after mixing. Spread with a squeegee and back roll with a quality solvent resistant 3/8 inch nap roller. Maintain a wet edge and do not roll material after it begins to set. Apply at 100 to 200 SFPG, depending on the target film build and system design. If the 24 hour recoat window is exceeded, abrade the surface with 80 to 100 grit until it is uniformly gloss free and dust free before recoating. System Limitations APF Epoxy Novolac 900 is not suitable for constant temperature exposure over 175°F. It is also not recommended as a clear topcoat for decorative applications. Before application, verify that the ambient temperature is at least 5°F above the dew point. Avoid kerosene or propane forced air heaters during installation, as they may cause discoloration or finish defects. OneStopEpoxy.com We ship Novolac and chemical resistant epoxy systems nationwide.

APF Oil Stop Primer | Epoxy Primer for Oil Contaminated Concrete Product Overview APF Oil Stop Primer is a professional grade 100% solids epoxy primer engineered specifically to bond to oil soaked and hydrocarbon contaminated concrete.

Surface must be free of loose coatings, wax, and heavy surface debris. Mechanically prepare the surface to a CSP 2 or CSP 3 profile. Vacuum thoroughly to remove all dust and debris before application. Pro Tip: Apply APF Oil Stop Primer immediately after grinding and surface preparation. On heavily oil-contaminated slabs, embedded oils can migrate back to the surface within hours. Delaying application increases the risk of adhesion failure, so it is best to prep and coat in the same window. Mixing and Application Mixing: Combine Part A and Part B at a 3 to 2 ratio. Mix with a low speed drill for 2 to 3 minutes. Scrape sides and bottom thoroughly. Apply immediately after mixing. Application: Pour in ribbons and spread with a squeegee. Back roll with a solvent resistant 3/8 inch nap roller. Technique: Back roll twice in a north south and east west pattern to ensure the resin fully wets the substrate. Recoat: Apply subsequent coats within 24 hours. If exceeded, sand with 80 to 100 grit until a uniform dull finish is achieved. Frequently Asked Questions Can I use this on a floor that currently has standing oil?No. While it bonds to contaminated concrete, you must first clean and degrease the surface to remove standing oil and surface muck before mechanical preparation. What happens if I use a regular primer on oil soaked concrete?Standard epoxies will likely bead up or fail to bond, leading to fish eyes in the coating and eventual peeling once vehicle tires or heat are introduced. Is this primer clear?Yes. It is a clear 100% solids epoxy. It is not designed to be tinted. Can I apply a flake system over this?Yes. This creates an ideal bond for epoxy base coats, flake systems, and polyaspartic topcoats on compromised slabs.
