Epoxy.com Product #830
MOISTURE VAPOR TREATMENT
Epoxy.com Product #830 is a two component modified epoxy system designed
to seal concrete and reduce moisture vapor transmission prior to applying
finished flooring. Epoxy.com Product #830 has proven to reduce moisture
vapor emissions and be resistant to damage from high alkalinity. Epoxy.com
Product #830 is an environmentally friendly material containing no
hydrocarbons or other solvents making it zero (0) VOC.
- Reduces moisture vapor transmission rate through concrete.
- Provides excellent resistance to highly alkaline conditions.
- Gives excellent bond to properly prepared concrete.
- Has convenient 2:1 mixing ratio.
- High physical properties.
- Can be rapidly surfaced with a variety of finished flooring
- Substrate temperature must be a minimum of 55oF before, during and
72 hours after installation.
- Must have effective vapor barrier directly under substrate.
- For use only on properly prepared surfaces; must be free of dirt,
waxes, curing agents and other foreign materials.
- Does not function as a crack reflective membrane.
- Epoxy.com Product #830 is designed as a negative side moisture vapor
retarder to reduce moisture vapor transmission through concrete.
- Epoxy.com Product #830 can also be an effective primer for fast
recoat under Epoxy.com flooring systems.
Epoxy.com Product #830 is a highly cross-linked, alkaline resistant epoxy

Surface preparation is the most critical portion of any
successful resinous flooring system. All substrates must be properly
prepared as outlined in Epoxy.com Surface
Preparation Guide. Work must be performed by trained or experienced
contractors or maintenance personnel.
Epoxy.com Product #830 is a moisture vapor suppressant for
concrete substrates. Surface and air temperature must be a minimum of 55oF
during installation and cure.
Concrete surface must be free of dirt, waxes, curing
agents, any other foreign materials, and must be structurally sound.
Surfaces should be vacuum shot blasted to “open” surface porosity or by
diamond grinding with coarse stones. Surface profile must be a minimum
CSP-4-CSP-5 profile according to International Concrete Repair Institute
Concrete surfaces should be tested for moisture
transmission according to ASTM-F-2170 (Relative Humidity in Concrete Floor
Slabs using in situ probes) and ASTM-F-1869 (Measuring Moisture Vapor
Emission Rate of Concrete Subfloor using Anhydrous Calcium Chloride).
Epoxy.com Product #830 may be applied in a single coat of
12 mils (130 sq.ft. per gallon) when relative humidity readings are below
95% or MVT readings are below 8# per 1000 sq. ft./24 hrs. Higher readings
require consultation with Epoxy.com Technical Services and may require a
second coat of Epoxy.com Product #830 of 10 mils (160 sq. ft. per gallon).
Fill all cracks and non-moving joints with Epoxy.com
Product #830. If material continues to disappear into the void, add fumed
silica to get a gel consistency and “putty” into the void to completely
seal. Detailing with Epoxy.com Product #32 membrane
and glass mesh is done after the Epoxy.com Product #830 application.
MIXING & SPREADING
Stir resin and hardener separately prior to mixing. Mix
ratio is 2 parts resin Part A to one part hardener Part B. Pour together and
mix thoroughly for 60-90 seconds. Apply at the rate of 120-130 sq.ft./gal.
Apply extra material to areas showing penetration and soaking into the
concrete. All areas should show a uniform gloss and a uniform 12 mils
Maximum recoat time for Epoxy.com Product #830 is 72
hours. It may be advantageous to prime with Epoxy.com Product #899 primer or
a second coat of Epoxy.com Product #830 at 200-250/sq. ft. and lightly
broadcast 30 mesh silica to help achieve a good mechanical bond.
For areas showing moisture vapor greater than 8#/1000sq.ft/24 hours or
humidity readings greater than 95% consult with Epoxy.com Technical
Proper mixing and installation is critical to the optimal success
of all product. See
MSDS for more details on our products.
