Epoxy Moisture Vapor Barriers
Membrane-Forming Moisture Mitigation Systems
Our epoxy vapor barriers:
- Meet the ASTM F3010-13 product requirements
- Reduce moisture vapor emission rates through the concrete slab
- Help control MVER up to 20 lbs/24 hr/1000 square feet
- Can be placed under epoxy and other polymer systems, along with Vinyl sheet goods, tiles, wood veneers and carpet
We offer various types of moisture vapor barriers from several manufacturers. All warranties will require MVER testing according to test methods F2170 or F1869.
Frequently Asked Questions
Our preferred chemical moisture vapor treatments are 100% solids; they contain to volatile organic compounds (VOCs).
These epoxy coatings are not designed to be the wear layer. Subsequent layers of a polymer system (epoxy, urethane, novolac, etc) are placed on the vapor barrier the following day.
In addition, the epoxy vapor barrier can serve as the mitigating system for other types of flooring, such as: carpet, tile, wood, VCT or sheet goods.
New concrete must cure for at least 10 days (we recommend longer) with a minimum compressive strength of 3,500 psi and a minimum tensile strength of 200 psi.
The answer to this depends upon the type of vapor barrier system used, type of testing performed and size of the job. We would need more information to answer this question.
Typically, no. Garages at or above grade with a stone base normally do not experience high moisture vapor emission rates (MVER). Garages below grade or where the slab is directly in contact with the earth may experience high MVER. An epoxy vapor barrier systems may help, but additional data will be required to determine suitability of this system.
If its newer residential construction and conforms with common construction codes and practices, usually not. Older homes or areas that have a high water table often experience higher moisture vapor emission rates and an epoxy vapor barrier may assist.
Testing would be required to determine the suitability of an epoxy vapor barrier.
