WATER-BASED MOISTURE PREVENTION

Nexus VB+ is a water based, pre-mixed liquid designed to penetrate deep into the concrete slab. Nexus VB+ is designed to stop hydrostatic pressure and reduce vapor permeability to protect surface applied coatings and adhesives from the effects of capillary moisture and vapor pressure. The organic and inorganic composition of Nexus VB+ penetrates to become an integral part of the concrete slab leaving no surface film or residue. Nexus VB+ permanently forms an internal capillary break preventing positive, negative and horizontal moisture intrusion. Nexus VB+ also forms an internal membrane film further sealing the capillary system from moisture migration and water vapor emissions to provide maximum protection.

MIXING AND APPLICATION:

Mix MVE2 Vapor Barrier Plus with a 250 to 400 RPM drill and mixing paddle before using. Do not add anything to thin or entrain air during mixing. A two coat concrete surface application of MVE2 Vapor Barrier Plus is recommended using a low pressure sprayer.

Fresh/Green Concrete:

MVE2 Vapor Barrier Plus is applied to Green Concrete as soon as the concrete can be walked upon without damage and surface water is not visible. Approximately 6 to 12 hours in typical conditions. Initial application rate is 300 to 400 square feet per gallon. Do not pond MVE2 Vapor Barrier Plus or oversaturate the fresh concrete surface. After sweeping or vacuuming the concrete surface, a second MVE2 Vapor Barrier Plus application is applied at 300 to 400 square feet per gallon after 7 days for optimum performance. Constantly broom any puddles until MVE2 Vapor Barrier Plus is absorbed into the slab.

Aged Concrete:

A two coat MVE2 Vapor Barrier Plus application is recommended to properly prepared Aged Concrete. The initial application rate is approximately 300 square feet per gallon. Absorption rates vary depending on the porosity of the concrete. Evenly distribute MVE2 Vapor Barrier Plus with a broom to remove excess material and puddles. The first application should be damp and absorbed in 20 to 30 minutes. After the first coat has been absorbed, but not dry, a second application is applied at a rate of 300 to 400 square feet per gallon. Constantly broom any puddles of MVE2 Vapor Barrier Plus
