Epoxy.com Product #830
MOISTURE VAPOR TREATMENT
DESCRIPTION
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.
ADVANTAGES
- 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
materials.
CONSIDERATIONS
- 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.
TYPICAL USES
- 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.

APPLICATION
SURFACE PREPARATION
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 Guideline #03732.
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 12# 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 minimum thickness.
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 12#/1000sq.ft/24 hours or
humidity readings greater than 95% consult with Epoxy.com Technical
Department.
