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. When standard primers fail due to embedded oils, this low viscosity formula penetrates deep into the slab to create a reliable and permanent bond. For garages, auto shops, and industrial floors exposed to motor oil, hydraulic fluid, or solvents, this product prevents delamination and provides your coating system a stable starting point. It is the definitive solution when the concrete is already compromised and you still need the floor to perform. Avoid Costly Concrete Replacement: Standard primers cannot bond to contaminated concrete, which leads to peeling and system failure. APF Oil Stop Primer is designed specifically for these conditions, allowing you to successfully coat difficult slabs so you don't have to rip out the floor and replace it. Key Benefits Bonds to Contaminated Surfaces: Specifically designed for slabs affected by oils, fuels, and hydrocarbons. Deep Anchor Penetration: Low viscosity formula helps the resin anchor into compromised concrete pores. Prevents Delamination: Creates a reliable base for epoxy, polyaspartic, and flake systems.

Technical Specifications Property Details Mix Ratio 3 Parts A to 2 Parts B Kit Size 1.25 Gallons Coverage Approximately 125 sq ft per kit Color Clear (Not Tintable) Surface Preparation Concrete must be cured for at least 30 days and structurally sound. 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.

APF VaporSolve LP | 99% RH Moisture Mitigation Epoxy APF VaporSolve LP (Low Perm) is a specialized, 100% solids epoxy coating engineered to isolate moisture-sensitive flooring systems from concrete with high moisture levels. It acts as a high-performance moisture mitigation layer, designed to prevent the devastating flooring failures caused by excessive moisture vapor transmission through the slab. VaporSolve LP is suitable for concrete substrates showing up to 99% Relative Humidity (RH) when measured in accordance with ASTM F2170. It is part of the proven APF VaporSolve system, formulated for low viscosity and superior substrate wetting to promote deep penetration and a permanent bond, even to damp concrete. Technical Performance Snapshot Physical Property Value Maximum Moisture Rating 99% RH (ASTM F2170) Permeability (ASTM E-96) 0.01 Perms Adhesion to Concrete (ASTM D-4541) >500 psi (Concrete Failure) Pot Life / Bucket Time (ASTM D2471) 10–15 Minutes at 77°F VOC Content <50 g/L Critical Bucket Time Warning: VaporSolve LP has an extremely short pot life of 10–15 minutes. You must pour the material out of the pail immediately after mixing. If left in the bucket, the material will rapidly generate heat and kick, significantly reducing your application window. Once spread on the cooler concrete surface, your actual working time will extend, but the material must get out of the pail immediately. The Silicate Conflict If the concrete surface is known or suspected to have been treated with silicates, densifiers, or reactive silicate curing compounds, the use of APF VaporSolve Primer is required before applying VaporSolve LP. Shot-blasting or diamond grinding alone will not reliably remove metasilicate residues from within the concrete pores. In these cases, the primer is a mandatory step to bridge the gap and ensure the system maintains a permanent bond. Where This Product Fits in a System APF VaporSolve LP is used below moisture-sensitive flooring systems (Epoxy, Urethane, Polyaspartic, or Cementitious Overlays) when elevated concrete moisture is present. It is a functional moisture control membrane designed to isolate the finished floor from moisture vapor coming through the slab. Packaging and Coverage Packaging: Supplied in complete A+B units in 1.5 gallon and 3.0 gallon kits. Use only as a complete mixed unit; do not break down into partial mixes. Coverage Rates: To achieve the 0.01 perm rating, the material must be applied at 100 sq. ft. per gallon (16 mils Wet Film Thickness). Proper coverage is critical because moisture mitigation is a thickness dependent application. If spread too thin, the system may fail to isolate moisture vapor effectively. Surface Preparation Concrete must be clean, structurally sound, and mechanically prepared to a minimum ICRI CSP 2 to 3 surface profile. The concrete must be free of wax, grease, loose coatings, curing compounds, and dust. Note: Acid etching is not 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. Mixing Instructions Thoroughly pre-mix Part A before adding Part B. Combine both components and mix for 2 to 3 minutes using a slow-speed drill and paddle mixer. Scrape the sides and bottom of the mixing container during mixing. Do not mix by hand. Do not mix at high speeds, as whipping air into the material can create bubbles, pinholes, and surface defects. Application Instructions Apply VaporSolve LP immediately after mixing. Spread the product with a squeegee and back-roll with a quality solvent-resistant 3/8-inch nap roller cover. The material must be rolled twice to achieve proper substrate wetting and to ensure a pinhole-free seal. Use a North-South and East-West rolling pattern to distribute the product evenly across the prepared concrete. Recoat within the 12–24 hour window. If the 24-hour window is exceeded, you must abrade the surface with 80–100 grit until it is uniformly gloss-free and dust-free before proceeding. Common Frequently Asked Questions Can I use this on "Green" concrete? Concrete typically needs to cure for 28 days before coating. While VaporSolve LP can handle high humidity, it is still recommended to wait for the concrete to stabilize. If you are on a fast-track construction schedule, please contact us to discuss the specific age of your slab before proceeding. Why is the Perm rating so important? A perm rating measures the rate of water vapor transmission. VaporSolve LP’s 0.01 perm rating reduces moisture vapor transmission to near zero, helping prevent failure of moisture-sensitive flooring systems installed above it. What happens if I see "Pinholes" after application? Pinholes occur when air escapes the concrete as the epoxy cures. This is common on porous slabs and should be expected in some cases. If you see pinholes after your first coat, you must apply a second tight coat. A single pinhole can allow moisture vapor to pass through and eventually cause a failure in the finished flooring system. Can I use this as my final garage floor finish? No. VaporSolve LP is a functional industrial resin. It is not UV stable and is not designed for aesthetics. It must be covered with a pigmented epoxy, decorative flake system, or appropriate topcoat. Do I need to sand before my next coat? If you apply your next layer within the 12 to 24 hour recoat window, no sanding is required. If you wait longer than 24 hours, the surface becomes too hard for a chemical bond and must be sanded with 80–100 grit to create a mechanical profile. Can I use Pigmented VaporSolve LP directly on concrete? Pigmented VaporSolve LP is designed to be applied over VaporSolve Primer. If you are applying directly to properly prepared concrete without a primer, use the clear version. Why can't I split the kits into smaller batches? The mix ratio for moisture mitigation products must be exact to maintain the permeability rating. Measuring by eye or in small batches leads to errors. Even small mix inaccuracies can create weak spots that allow moisture to pass through, leading to system failure. Always mix the full kit as supplied.

APF VaporSolve® Primer | Adhesion Primer for Silicate Treated Concrete Product Overview APF VaporSolve® Primer is a specialized water based epoxy primer engineered exclusively for the VaporSolve moisture mitigation system. This product is not a standalone moisture vapor barrier (MVB). Its primary purpose is to serve as the critical "bridge" between challenging concrete substrates and the protective moisture barrier coat. It is specifically designed to solve adhesion failures on concrete slabs treated with silicate based curing compounds or densifiers—surfaces where traditional epoxy primers simply cannot bond. When used as the foundation for VaporSolve LP, it ensures the entire system remains anchored even under extreme hydrostatic pressure and high alkalinity. IMPORTANT: APF VaporSolve® Primer is an adhesion promoter, not a moisture barrier. It must be topcoated with VaporSolve LP to achieve moisture mitigation. Do not purchase this as a standalone solution for moisture vapor; it is specifically for bonding to high moisture slabs and concrete treated with silicates or densifiers. Where This Product Fits System Foundation: The mandatory first coat for the VaporSolve moisture mitigation system. Silicate Bond Specialist: Formulated to penetrate concrete treated with sodium or potassium silicates. Damp Slab Integration: Safely adheres to green or damp concrete where solvent primers fail. Alkalinity Defense: Uses Bisphenol F resin technology to resist the high pH environments common in wet slabs. Key Features Substrate Penetration: Low viscosity allows the resin to wet out and anchor into dense concrete pores. System Specific: Engineered to work in perfect chemical harmony with VaporSolve LP. Water Based & Low Odor: Safe for use in schools, hospitals, and occupied residential spaces. Wide Application Window: Reliable curing in temperatures ranging from 40°F to 100°F. Technical Specs & Mixing Property Details Coverage Approximately 200 sq ft per gallon Mix Ratio Do not mix partial kits Water Addition 1 gal water (3 gal kit) | 1 qt water (0.75 gal kit) Next Step Apply VaporSolve LP within 24 hours Surface Preparation Concrete must be mechanically prepared to a CSP 2 or CSP 3 profile. Remove all wax, old coatings, and loose contaminants. Vacuum thoroughly; the primer must reach the open pores of the concrete. Important: Acid etching is not an approved prep method for moisture mitigation systems. Mixing Instructions Pour entire contents of Part B into Part A. Mix for 2 to 3 minutes with a low speed drill (300 to 450 RPM). Add Water: Add the required amount of clean potable water and mix again for 2 to 3 minutes until uniform and creamy. Apply immediately. Pour material onto the floor within 3 minutes of mixing to maximize penetration. Frequently Asked Questions Can I skip the primer and just use VaporSolve LP?If your concrete has been densified or treated with silicates, skipping this primer will likely lead to a bond failure. This primer is the only layer engineered to bite into those silicate residues. How long do I wait before applying the VaporSolve LP barrier coat?Apply the LP barrier coat as soon as the primer is tack free, typically within 6 to 12 hours. Do not wait longer than 24 hours without mechanical sanding. Is this the same as a standard water based epoxy?No. This is a Bisphenol F resin system designed specifically for the extreme alkalinity and vapor pressure found in moisture mitigation environments. Does this primer come in colors?No. VaporSolve Primer is a clear system. Its job is substrate penetration, not aesthetics. Color is introduced in the subsequent coating layers. Do I need to wash the floor before priming?Mechanical grinding is the best prep. If the slab is dirty, it must be degreased and neutralized before grinding. The primer must reach clean, open concrete to work.
