Good to know
- Test the slab and get a number before you specify. Tex Tuff-MVB controls emission rates up to 25 lb per 24 hr per 1000 sq ft, so the test result tells you directly whether it is the right product.
- It cures quickly at ambient and low temperatures while still offering extended pot life, which is a rare pairing on an epoxy and useful on cool weather schedules.
- It can serve as primer, bonding agent or topcoat, so on many builds it handles moisture control and the bond coat in one pass.
- A vapor barrier does not replace prep. Grind or shot blast to profile, patch and vacuum before it goes down.
- Ships as a regulated liquid under ground shipping rules. Call 817-676-6793 for freight on large or pallet orders.
About the Tex Tuff MVB Kit
Tex Tuff-MVB is a 100 percent solids, two component moisture vapor barrier epoxy that acts as a moisture vapor retarder for concrete and for finished floor coverings including vinyl tile, sheet vinyl and hardwood. It is supplied clear in 3 gallon kits.
The number that decides the job is the emission rate. Tex Tuff-MVB effectively controls moisture vapor emission rates up to 25 pounds per 24 hours per 1000 square feet. That is a specific published limit, which is what you need when a general contractor or flooring manufacturer is asking what the slab was treated with. Test the slab, get the number, then check it against that limit before you specify.
System position is flexible. It can function as a primer, as a bonding agent, or as a topcoat, which means it can serve as the moisture control layer and the bond coat in a single pass on a lot of builds. It offers an extended pot life while still achieving quick cure at ambient and low temperatures, which is a genuinely useful pairing: working time on the floor without giving up the schedule, and it will still cure when the slab is cool. Mechanical properties are strong and chemical resistance is good.
The common use case is flooring installed over a slab that will not stop giving off moisture, which covers most slabs on grade poured without a functioning vapor retarder. Vinyl adhesive lets go, hardwood cups, coatings blister. A vapor retarder installed correctly under the system is the fix. Mix ratio, coverage and recoat windows are on the technical data sheet, available on request at 817-676-6793.
What it is used for
- Slabs on grade with high moisture vapor emission
- Under vinyl tile, sheet vinyl and hardwood installations
- Priming and bonding under epoxy and urethane floor systems
- Cool weather installs needing quick cure at low temperatures
- Fast track projects over concrete that has not fully dried
Before you order
Work out how much you need
The most common ordering mistake in this category is buying by the gallon instead of by the floor. Coverage changes with porosity, profile and whether the coat is a base, a broadcast or a topcoat. Put the slab dimensions in and get a range rather than a single number.
How much material do I need?
Enter the slab. We will give you a range, because porosity and surface profile change real coverage.
- Floor area
- 400 sq ft
- Base coat
- 3.1 to 3.4 gal
- Topcoat (1 pass)
- 3.1 to 3.4 gal
- Flake
- about 8 x 25 lb boxes
Base coat, flake broadcast to rejection, then a clear topcoat. Order roughly 10% over on a first job.
Questions about this product
What moisture level can Tex Tuff-MVB handle?
Tex Tuff-MVB effectively controls moisture vapor emission rates up to 25 pounds per 24 hours per 1000 square feet. Run a calcium chloride or relative humidity test on the slab first, then check the result against that limit, because a slab above it needs a different approach entirely.
Can Tex Tuff-MVB be used under vinyl and hardwood flooring?
Yes. Tex Tuff-MVB is designed to act as a moisture vapor retarder for concrete and for finished floor coverings including vinyl tile, sheeting and hardwood. That covers the classic failures on a wet slab: adhesive releasing under vinyl, hardwood cupping and coatings blistering months after installation.
Can Tex Tuff-MVB be used as a primer?
Yes. Tex Tuff-MVB can function as a primer, a bonding agent or a topcoat, so on many builds it handles both moisture control and the bond coat in a single pass. Confirm intercoat compatibility and the recoat window with the system going over it before you schedule the work.
Does Tex Tuff-MVB cure in cold conditions?
Tex Tuff-MVB achieves quick curing at ambient and low temperatures while still offering an extended pot life, which is an unusual pairing for an epoxy and useful on cool weather schedules. Confirm the specific minimum application temperature on the technical data sheet before a cold install.
How much does a 3 gallon Tex Tuff-MVB kit cover?
Coverage for Tex Tuff-MVB depends on the film build needed to form a continuous vapor retarding layer and on how porous and profiled the slab is. The technical data sheet carries the rate for each application. Call 817-676-6793 with your square footage and slab test results and we will size the order.
