MavPrime MVT Moisture-Tolerant Epoxy Primer

Where MavPrime MVT Is Used

• Fast-track construction projects
• Green concrete primer under Maverick epoxy and polymer floor coatings
• Under vinyl tile and carpet
• As a standalone coating or sealer
• Pigmented as a coating system
• Over high-moisture underlayments

Read Before Specifying

• MavPrime MVT is not designed for exterior use or constant immersion applications.
• Confirm product performance in the specific chemical environment prior to use.
• Prepare the substrate according to the surface preparation requirements.
• Do not apply to slabs on grade unless a heavy, unruptured vapor barrier has been installed under the slab.
• Do not apply at a temperature or thickness not recommended.
• Always use protective clothing consistent with OSHA regulations during use.
• 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 and sound concrete that is free of coatings, sealers, curing compounds, oils, greases or other contaminants that may affect adhesion. 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. Measure concrete relative humidity before application: up to 85% RH, one 8 – 10 mil coat is sufficient; above 85% RH, apply two full 8 – 10 mil coats. Do not apply to slabs on grade unless a heavy, unruptured vapor barrier has been installed under the slab. Because outgassing may occur on porous concrete, apply 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

MavPrime MVT is mixed 2 Parts A (Resin) to 1 Part B (Hardener) by volume. Pre-mix Part A; if pigmenting, add pre-mixed MavTints to Part A at one color pack per 3 mixed gallons (two packs for white, light, and safety colors). 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 since unmixed material will not cure. Apply by roller, or by squeegee and back-roll, emptying the pail onto the concrete quickly to maximize working time, as material left in the pail generates heat and loses pot life. For concrete above 85% RH, apply two full 8 – 10 mil coats, using two colors or a clear first coat and pigmented second coat to aid complete coverage; below 85% RH one coat is sufficient, though two coats help ensure complete coverage. For a non-skid texture, add clean, dry aggregate. 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.
