waterborne moisture vapor control system

Perdure MVT-W is a low viscosity, waterborne emulsion, epoxy primer used as a moisture mitigation treatment on concrete with excessive moisture vapor transmission. Perdure MVT-W will endure moisture vapor emission rates up to 10lb/1000ft2/24hr as tested according to ASTM F1869-11 and relative humidity of 90% in the concrete slabs tested according to ASTM F2170-11.

Description

Perdure MVT-W is a low viscosity, waterborne emulsion, penetrating epoxy primer formulated to be used as a moisture mitigation treatment on concrete with excessive moisture vapor transmission. Perdure MVT-W will endure moisture vapor emission rates up to 10lb/1000ft2/24hr as tested according to ASTM F1869-11 and relative humidity of 90% in the concrete slabs tested according to ASTM F2170-11.

NOTES:

It is important to understand the difference between moisture vapor transmission and moisture content. You may have low moisture content and have a bond failure at some point in the future due to vapor transmission through the slab. A high moisture content in the slab will usually not cause a problem unless conditions are right to cause movement of that moisture to the surface. So, its moisture transmission to the surface whether it is from high moisture content in the slab or under the slab that causes the problem.

Allowable moisture vapor transmission for duraamen™ flooring systems
The maximum moisture vapor transmission through concrete when tested as per the Calcium Chloride Test, should not exceed 3.0lbs/24hr/1000 sq. ft.
