Designed for one day floor installations, 150FC performs exceptionally well in hot and humid environments, offering a rapid return to service without the "flash cure" risks of inferior fast-setting epoxies. The 150FC Technical Advantage 3-in-1 System: Acts as a high-strength primer, pigmented base coat, and MVB rated up to 12 lbs. 90-Minute Recoat: Fast cure profile allows for scraping and top coating in as little as 90 minutes in warmer temperatures. Extended Working Time: Provides 20 to 30 minutes of open time on the floor nearly double that of traditional rapid cure epoxies. UV Considerations: Engineered for full broadcast systems (flake, quartz, sand) where the epoxy is fully covered to prevent visible ambering. Best Uses for Fast Cure Epoxy One Day Flake Floors: The industry standard for rapid garage and commercial prep. Sand & Quartz Broadcasts: Ideal for industrial non-slip systems requiring fast turnaround. Humid Climates: Specifically formulated to remain manageable in high-humidity markets like Florida. Mixing and Application (Critical for Success) Pro Warning: 150FC is for experienced installers. It requires mechanical surface prep (CSP 2-3) and must be poured in ribbons immediately after mixing to avoid exotherm in the bucket. Mix Ratio: 2 Parts A to 1 Part B. Mix Time: 2 minutes if above 75°F; 3 minutes if below 75°F. Mixer: Use a box or cage style mixer for full kits. Working Time: 20–30 minutes depending on ambient temperature. Frequently Asked Questions Is this a good epoxy for garage floors?Yes. It is the preferred base coat for professional installers performing one day full flake garage floor installations. What makes 150FC different from other fast cure epoxies?150FC includes a built-in moisture vapor barrier (up to 12 lbs) and offers significantly more working time on the floor than standard rapid-set resins. Can I use this for a one day flake floor?Yes. This is the primary use for 150FC. Its fast cure profile allows you to prep, base, flake, and topcoat in a single shift. Why can’t this be used for solid color floors?Because 150FC is a fast-cure aromatic epoxy, it will amber under UV exposure. It must be used in a broadcast system where it is completely covered by flakes, sand, or quartz. Is this product beginner friendly?No. 150FC is designed for experienced contractors who understand how to manage fast-curing materials and jobsite pacing. Does this replace a moisture vapor barrier?Yes. It is rated to block moisture vapor transmission up to 12 lbs, eliminating the need for a separate MVB primer step. How long does 150FC take to dry before I can topcoat?Depending on temperature and humidity, you can typically sweep, vacuum, and topcoat in as little as 90 minutes. What is the working time for this fast cure epoxy?Depending on temperature, you will have between 20 and 30 minutes of working time once the material is poured onto the floor. Can 150FC be used outdoors?Yes, provided it is part of a full broadcast system where the epoxy is entirely covered and protected from UV exposure. Do I need to add solvent to thin this product?No. This is a true 100% solids epoxy. Adding solvents will compromise the cure and the moisture vapor barrier rating.

Moisture Vapor Barrier Epoxy | 25 lb Rated 100% Solids MVB One Stop Epoxy 100% Solids Moisture Vapor Barrier Epoxy is a professional-grade foundation coating engineered to block moisture vapor transmission through concrete slabs. Rated for extreme conditions up to 25 lbs of moisture vapor emission, this product creates a permanent barrier that prevents the most common causes of floor failure: peeling, bubbling, and delamination. This is not a finish coat or a receiver coat. It is a critical insurance policy used to stabilize concrete before installing a 100% solids epoxy build system. Why Professionals Use a 25 lb Rated MVB Concrete is naturally porous and acts like a sponge, releasing moisture vapor for years. When this vapor pressure builds up beneath a standard coating, it physically breaks the bond, leading to total system failure. Our MVB Epoxy solves this by penetrating deep into the concrete capillaries to create a structural seal that can handle high hydrostatic pressure. Extreme Moisture Resistance: Rated to block up to 25 lbs of vapor transmission—far exceeding standard epoxies. Prevents Osmotic Blistering: Stops the bubbles that form when moisture is trapped under the floor. Superior Bond Strength: Provides a stabilized, non-porous surface for your next epoxy layer to lock onto. Zero VOC Formulation: 100% solids with no odor, making it safe for interior and basement applications. The Proper System Sequence To ensure a lifetime bond on slabs with moisture concerns, follow the professional "Step-Up" method: The Barrier: Apply One Stop MVB Epoxy directly to mechanically profiled concrete (CSP 2-3). The Build Coat: Once cured, apply a layer of 100% Solids Self Leveling Epoxy. This acts as your pigmented base or "receiver coat" for flakes. The Finish: Complete the system with a high-performance Polyaspartic or Urethane topcoat. Mixing and Application Requirements Pro Tip: Do not broadcast flakes or quartz directly into the MVB. This material must be applied as a continuous, unbroken film to effectively block moisture. Mix for a full 3 minutes to ensure the chemical barrier is fully cross-linked. Mix Ratio: 2 Parts A to 1 Part B. Mixer: Use a box or cage style mixer at 300 to 450 RPM. Coverage: 100 to 150 square feet per gallon depending on porosity. Dry Time: 8 to 10 hours at room temperature. Frequently Asked Questions Do I need a moisture vapor barrier epoxy?If moisture is present, unknown, or if you are installing over a slab on grade, this is a necessary preventative step to avoid total coating failure. How do I know if my concrete has a moisture problem?Visible signs include efflorescence (white powder) or dark spots. The only certain way is testing, but applying MVB is the safest preventative measure for any slab where the history is unknown. Can I use this for basement floors?Yes. Basements are inherently prone to moisture issues. Using this vapor barrier is the best way to ensure your basement epoxy floor never peels or bubbles. Can I broadcast flakes directly into the MVB?No. The Moisture Vapor Barrier must be applied as a clean, continuous film to seal the slab. After it cures, you apply a 100% solids epoxy layer to serve as your pigmented receiver coat for flakes. Is this required for garage floors?It is highly recommended in humid environments, on older slabs, or if you are a professional installer offering a long-term warranty to your clients. What happens if I skip this step?Skipping moisture control on a high-vapor slab leads to osmotic blistering and total system delamination, requiring a costly total replacement. Can this be used as a finished floor?No. This is a functional base layer designed to stabilize the slab. It must be covered by a 100% solids epoxy build coat and an appropriate topcoat. What should I use over this product?Typically, installers follow this with a 100% solids epoxy (like our Self Leveling or 150 Fast Cure) before moving to their decorative broadcast or topcoat. How long do I have to wait before applying my next coat?The material is generally dry to the touch in 8 to 10 hours. You should apply your next coat of epoxy within 24 hours to ensure a strong chemical bond. What is the mix ratio?The mix ratio is 2 parts Part A to 1 part Part B. Mix thoroughly with a drill mixer for a full 3 minutes before pouring.

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.

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.

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.
