MavCoat NV Novolac Epoxy Coating

Where MavCoat NV Is Used

• Process area floors
• Chemical processing plants
• Battery charging areas
• Truck loading / unloading areas
• Secondary containment
• Pump pads, pedestals, and curbs
• Chemical-resistant topcoat over Maverick flooring systems, including MavCrete UM

Read Before Specifying

• MavCoat NV is not designed for exterior use. Suitable for immersion service – immersion samples available upon request.
• MavCoat NV may stain when exposed to certain chemicals.
• Confirm product performance in the specific chemical environment prior to use.
• Do not apply to slabs on grade without a heavy, unruptured vapor barrier, or where moisture / MVT is present.
• Prepare the substrate according to the surface preparation requirements.
• Do not apply at a temperature or thickness not recommended.
• Refer to the Safety Data Sheet (SDS) for detailed safety precautions.
• For industrial/commercial use. Installation by trained personnel only.
• Do not allow materials to freeze.

Substrate Requirements

Apply only to clean, dry, and sound concrete that is free of coatings, sealers, curing compounds, oils, greases or other contaminants that may affect adhesion. New concrete should be cured a minimum of 28 days; for green concrete, prime with MavPrime MVT. Chemically contaminated concrete must be neutralized or removed, and any laitance or weak surface layers removed. Concrete must have a minimum surface tensile strength of 300 psi per ASTM D4541 and be mechanically prepared to a CSP 3 – CSP 5 profile per ICRI Guideline 310.2R (equal to 60-grit sandpaper or coarser), with all surface irregularities, cracks, expansion joints and control joints addressed before application. Do not apply to slabs on grade unless a heavy, unruptured vapor barrier has been installed under the slab; moisture vapor transmission must be 3 lbs. or less per 1,000 sq. ft. in 24 hours per ASTM F1869 and in-situ relative humidity below 75% per ASTM F2170. Because outgassing may occur on porous concrete, apply primer and coating while the substrate temperature is dropping (typically evening); double priming greatly reduces outgassing. Air temperature 50° – 95°F (10° – 35°C); the surface must be at least 5°F above the dew point.

Mixing and Installation

The concrete is first primed with MavPrime EP at 200 – 533 sq. ft./gal. (3 – 8 mils), or with MavPrime MVT on green concrete. MavCoat NV is mixed 2 Parts A (Resin) to 1 Part B (Hardener) by volume: pre-mix Part A, add one pre-mixed MavTints color pack per 3 mixed gallons if pigmenting, then pour Part B into the Part A pail and mix for a minimum of two minutes with a Jiffy-type mixer at low speed, scraping the sides of the pail. Apply by roller, or by squeegee and back-roll, emptying the pail onto the concrete quickly to maximize working time; back-roll lightly and do not over-roll, as excess rolling may introduce air bubbles. For a non-skid finish, broadcast clean, dry silica sand or aluminum oxide into the wet resin, then remove all excess aggregate and scrape the floor before the second coat. Apply the second coat after the first is tack free (approx. 10 hours @ 70°F) and before the 24-hour recoat window closes; if the window is missed, the coating must be sanded before recoating.
