VB 225™ FS

FAST-SETTING MOISTURE VAPOR EMISSIONS REDUCTION SYSTEM

DESCRIPTION

VB 225™ FS is a fast-setting, one-coat moisture

vapor reduction system, consisting of a unique

combination of of 100% solids epoxy resin and

other chemical compounds. VB 225™ FS is formu-

lated to cure in the shortest time possible and

prevent floor failures on concrete slabs containing

elevated levels of moisture vapor emission. VB 225

™ FS has no upper limits for water vapor emis-

sions; it resists moisture levels (100% RH) and a

sustained pH of 14. VB 225™ FS is extremely dense

with a perm rating of 0.05 grains/ft²/hr in Hg-¹. The

low perm rating makes VB 225™ FS perfect as a

primer for virtually all types of flooring, especially

low-permeance flooring, such as sheet goods,

rubber tile, and epoxy coatings. Its fast (2-3-hour)

cure time allows for extremely fast turnaround for

the installation of finished flooring and coatings.

VB 225™ FS exceeds ASTM F3010-13 (require-

ments for two-component, resin-based, mem-

brane- forming, moisture mitigation systems for

use under resilient floor coverings.)

VB 225™ FS’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.

APPLICATIONS

Formulated to treat new or existing concrete floors

with moisture and/or alkaline conditions that

prevent or compromise the installation of floor

covering systems.

May be installed on concrete with moisture vapor

emissions rates over 25+ lb/24hr/1000 ft² or 100%

RH. (Contact your Penetron representative for

MVER rates greater than 25 lb.)

Unaffected by a pH of 14. VB 225™ FS’s low perme-

ability of 0.05 grains/ft²/hr in Hg-¹ offers long-term

protection under VCT, sheet-vinyl, wood, rubber,

epoxy, polyurethane, and solid backed carpet.

May be used as a finished floor. Contact a Penetron

representative for finished floor limitations and

details.

Can be applied on concrete slabs in offices, hospi-

tals, schools, super-markets, manufacturing

facilities, airplane hangars, residential housing,

and many other applications.

Low odor and fast cure allow for application in

occupied buildings with minimum disruption.

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

10 to 15 lb/1000 ft²/24 hr

150 ft²/gal; approx 10 mils

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)

Product may be applied to concrete 5-7 days after placement for on-grade

and below-grade applications, where concrete is placed per design, and

only specified water of convenience is present. VB 225™ FS can be applied

at the rate of 125 ft²/gal (3.1 m²/l) at 100% RH. Proper ACI guidelines must

be met for good concrete placing practices and slab vapor barriers, per

ASTM E1745.

STORAGE / SHELF LIFE

12 months from the manufactured date. Always keep in cool/dry place

unexposed to sunlight. VB 225™ FS must NOT be subject to freezing, both

in shipping and storage.

A/B packaging).

DIRECTIONS FOR USE

Surface preparation:

Concrete substrates to receive VB 225™ FS must be structur-

ally sound, solid, absorptive and meet acceptable industry

standards, as defined in ACI Committee 201 Report “Guide to

Durable Concrete”. Surfaces must be free of adhesives, coat-

ings, curing compounds, concrete sealers, efflorescence, dust,

grease, oils, and any other material or contaminant that may

act as a bond breaker. Building envelope must be in place and

environmentally stable prior to product application.

Penetron Specialty Products Inc. recommends older, existing

concrete slabs be cored and analyzed for various contami-

nants, such as sulfurous salts, ASR (Alkali Silica Reaction),

unreacted water-soluble silicates and any other deleterious

compounds that may act as bond breakers (water-soluble

silicates are found in some curing compounds, floor harden-

ers and other vapor reduction products.) Slabs that have exist-

ing flooring failures are strongly recommended to have core

samples taken to identify the failure mode or identify any dele-

terious constituents in the concrete. It is the owner or the

owner’s representative’s responsibility to test the slab for

contaminants. These tests are not required by Penetron

Specialty Products Inc.

Contact Penetron Specialty Products Inc. technical staff for

additional details and guidelines concerning this type of

testing.

All patching, leveling materials, adhesives and old coatings

must be entirely removed prior to VB 225™ FS application.

Consult with Penetron Specialty Products Inc. prior to install-

ing any underlayments underneath VB 225™ FS.

Shot blast or mechanically prepare the substrate to an ICRI

Concrete Surface Profile (CSP) of 3-4. Grinding is permitted

only in areas inaccessible to shot blasting or for edging

purposes.

Acid etching is not permitted. Upon completion of the bead

blasting and grinding, the concrete slab must be vacuumed

free of all dust, dirt and debris prior to VB 225™ FS installation.

Do not use sweeping compounds that may contain oil or other

type chemical that may act as a bond breaker.

The concrete surface must be at least 5°F (-15°C) above the

Dew Point temperature. Avoid application in a dew point atmo-

sphere or when the ambient relative humidity is above 95% or

the concrete surface is wet.

On projects that have experienced a flooring failure of any type,

a minimum of an ICRI CSP-4 is recommended for surface

preparation.

Testing to determine the water vapor content of the substrate,

either the calcium chloride tests (ASTM F1869) or RH probe in

situ tests (ASTM F2170), may be used.

Application instructions:

Mix components A and B by combining both parts in total. Do

not mix partial kits. Pour the B component into the short-filled

A component container, while continually mixing. Mix with a

slow speed motor (<400 RPM) and “Jiffy-type” mixing paddle,

continuously for 3 minutes. Pour the fully mixed material onto

the substrate immediately after mixing, emptying the can

completely.

VB 225™ FS is applied in one coat using a squeegee and 3/8”

nap epoxy rated roller cover. VB 225™ FS is poured from the

container upon completion of mixing and spread with a squee-

gee to the appropriate coverage rates. VB 225™ FS is then

back rolled at right angles (90 degrees) to the squeegee appli-

cation, evenly distributing product across the area to be treat-

ed with no missed areas. As VB 225™ FS is absorbed and

penetrates into the surface of the concrete slab, air is

displaced in the concrete capillaries, resulting in “out

gassing”. Out gassing channels are self-healed during the

curing of VB 225™ FS and do not affect performance or

warranties. If the prepared substrate is subject to excessive

out gassing or pin-holing during the application of the VB 225™

FS, contact the Penetron Specialty Products Inc. technical

staff for additional recommendations. High points created by

the displacement can be scraped, lightly sanded, or skim

coated if needed to produce an acceptable level, smooth

surface. Concrete surface profile, absorption rate and mois-

ture vapor rates will determine coverage requirement.

Apply VB 225™ FS at substrate and ambient temperatures

between 50° to 90°F (10° to 32°C). Provide ventilation for

VB 225™ FS during application and cure time. The maximum

recoat window is 14 days. Prior to the installation of any

subsequent flooring systems, adhesives or coatings, the cured

VB 225™ FS must be clean and free of all dust, dirt and debris.

Sanding is not required. If VB 225™ FS application is to remain

uncovered for an extended period of time, contact the

Penetron Specialty Products Inc. technical staff for additional

guidelines. If installing MMA’s or PMMA’s, the maximum recoat

window is 48 hours after VB 225™ FS has cured for 4 hours

(may vary depending on environmental conditions).

Treating cracks and expansion joints:

Prior to installing the VB 225™ FS, cracks and voids should be

completely cleaned out and repaired using SURFIX™ FEP or

VB 225™ FS

VB 225™ FS mixed with an appropriate epoxy thickening agent. Cracks on

existing concrete slabs that may be contaminated should be cut out 1/4x1/4

inch (6x6 mm) to remove the contaminants from the side walls. Expansion

joints must be honored using the standard backerod method. Contact the

Penetron Specialty Products Inc. technical staff for additional information.

Underlayments/Leveling compounds:

Cementitious underlayments/leveling or skim coatings are not required over

VB 225™ FS, but are commonly used to smooth or level the VB 225™

FS-coated surface in preparation for subsequent floor coverings and

systems as required. VB 225™ FS is not formulated to be a floor leveling

product.

All underlayments, leveling or skim coats must be applied on top of the

cured VB 225™ FS, unless otherwise specified by your Penetron representa-

tive or the Penetron Specialty Products Inc. technical staff. For proper adhe-

sion, always use an appropriate primer for non-porous surfaces, such as

PRIMER STX 100™, prior to the installation of any cementitious material.

Check with your Penetron representative when using any other manufactur-

er’s primers.

DO NOT INSTALL VB 225™ FS OVER ANY GYPSUM-BASED PRODUCTS.

Adhesives/Coatings:

Most flooring systems, adhesives and coatings may be applied directly to the

cured VB 225™ FS. Adhesives and coatings must be designed and formulat-

ed for use over a non-porous substrate. There is no absorption of any fluid

or solvents from the adhesive into the VB 225™ FS-coated concrete. Apply

adhesives to a test area to check for compatibility prior to overall applica-

tion.

Adhesives, containing solvents (includes water) that are not allowed to flash

off prior to the flooring installation, may be applied to a minimum of 1/8 inch

(3 mm) of a cementitious underlayment. Check with the adhesive manufac-

turer’s recommendation for installation over an underlayment and the

required thickness for use as a “blotter.”

CLEAN UP

Clean tools and equipment immediately after use with xylene or similar

solvent. Store and dispose of cleaning solvent and rags according to job-site

rules and applicable regulations.

JOB MOCKUPS
