Perdure MVT is a two-component low viscosity Epoxy-based moisture vapor barrier designed to seal concrete and reduce moisture vapor transmission prior to applying finished flooring. Its formulation is based upon Mannich base curing agent. Perdure MVT has proven to reduce moisture vapor emissions and be resistant to damage from high alkalinity.

Perdure MVT is designed as a negative side moisture vapor retarder to reduce moisture vapor transmission through concrete.

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. 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.

Features

• Reduce the moisture vapor transmission rate through concrete.
• Provides excellent resistance to highly alkaline conditions.
• Gives an excellent bond to properly prepared concrete.
• Can be rapidly resurfaced with a variety of finished flooring covering materials
