Moisture Vapor Transmission Mitigation Coating Systems

Moisture Vapor Mitigation Systems

Site conditions can contribute to a concrete slab demonstrating undesirably high moisture vapor transmission levels. When this occurs, moisture vapor finds tiny pathways upward through the slab via capillary action, finally condensing into a high-pH liquid. Buildup of this alkaline liquid on the concrete floor surface can destroy the ability of industrial flooring to bond to the concrete substrate. In addition to the FloroCrete lineup of urethane mortar systems you also have available superior moisture vapor mitigation systems that may be applied beneath a range of coatings.

Floropoxy MVT Primer Moisture Mitigation System

Floropoxy MVT Primer Low Level Moisture Mitigation System

Floropoxy MVT Primer is a two component, 100% solids alkali resistant epoxy primer that provides superior protection to concrete surfaces subjected to moisture vapor transmission. The economical MVT system provides protection from lower levels of moisture vapor emission rates (MVER). For excessively high moisture vapor transmission rates choose Floropoxy MVT 24 Primer.

VB 225 Moisture Vapor Emissions Reduction System

VB 225 is a one-coat moisture vapor reduction system, consisting of a unique combination of 100% solid epoxy resins and other chemical compounds. VB 225 is formulated to prevent floor failures on concrete slabs containing elevated levels of moisture vapor emission. VB 225 has no upper limits for water vapor emissions; it resists moisture levels (100% RH) and a sustained pH of 14. VB 225 is extremely dense with a perm rating of 0.05 grains/ft²/hr in Hg-¹. VB 225 exceeds ASTM F3010-13 requirements for two-component, resin-based, membrane- forming, moisture mitigation systems for use under resilient floor coverings.

VB 225 MOISTURE VAPOR EMISSIONS REDUCTION SYSTEM

DESCRIPTION

VB 225™ is a one-coat moisture vapor reduction system, consisting of a unique combination of 100% solid epoxy resins and other chemical compounds. VB 225™ is formulated to prevent floor failures on concrete slabs containing elevated levels of moisture vapor emission. VB 225™ has no upper limits for water vapor emissions; it resists moisture levels (100% RH) and a sustained pH of 14. VB 225™ is extremely dense with a perm rating of 0.05 grains/ft²/hr in Hg-¹. The low perm rating makes VB 225™ perfect as a primer for virtually all types of flooring, especially low-permeance flooring, such as sheet goods, rubber tile, and epoxy coatings. VB 225™ exceeds ASTM F3010-13 (requirements for two-component, resin-based, membrane- forming, moisture mitigation systems for use under resilient floor coverings.)

VB 225™’s compliance with all state and federal VOC regulations with a VOC content of <10 g/l allows installation in sensitive areas, such as active hospitals, schools and grocery stores.

ASTM E96 test results:

Water Vapor Transmission, grams h-¹ m² 0.021

Water Vapor Transmission, lb/1000 ft²/24 hr 0.1

Avg. Measured Permeance, grains h-¹ ft² in Hg-¹ 0.05

Suggested coverage rates: Spread and mil rates are approximate and may vary due to the porosity, absorption rate and surface profile (CSP) of any given concrete substrate.

Vapor testing per ASTM F1869 (CACL) protocol:

Up to 10 lb/1000 ft²/24 hr 150 ft²/gal; approx 10 mils

10 to 15 lb/1000 ft²/24 hr 125 ft²/gal; approx 13 mils

15 to 25 lb/1000 ft²/24 hr 100 ft²/gal; approx 16 mils

Relative humidity testing per ASTM F2170 or ASTM F2420:

Due to the disparity between the (slab) RH and the CA-CL moisture tests, there is no spread rate correlation between the two test protocols. Use the following table for approximate spread rate guidance when using only the RH test values. Contact Penetron Specialty Products, Inc. technical staff

on any questions or concerns regarding product spread rates.

< 85% RH 150 ft²/gal (3.7 m²/l)

85-90% RH 125 ft²/gal (3.1 m²/l)

90-100% RH 100 ft²/gal (2.5 m²/l)
