Moisture Mitigation System
For Concrete Floors
Product #3100
Product Description
Product #3100 Moisture Mitigation System consists of a cementitious urethane primer/basecoat broadcasted
with silica sand, for use as a moisture vapor treatment on concrete floor slabs or elevated lightweight
concrete with excessive moisture vapor emission rates or a high internal moisture content. Product #3100
Moisture Mitigation System will tolerate moisture vapor emission rates (MVER) up to 25 lbs moisture per
1,000 square feet per 24 hours when tested in accordance with ASTM F1869. When tested in accordance with
ASTM F2170 it will tolerate 100% internal relative humidity.
Uses
Designed for use as a moisture mitigation system underneath Epoxy.com flooring systems.
Environment & Health
Follow the appropriate Occupational Health and Safety guidelines applicable to the location where
the application is undertaken. For more information, please refer to the safety data sheets for
the individual product components.
Mixing
Product #3100 Ratio of Components
Product #3100 Moisture Mitigation System is supplied in full units as A + B + Filler C + Oxide Pigment
Pack (optional). Do not split the components as this may jeopardize proper curing. Part B and C
must be stored dry or clumping of part C is possible and a reduction of active powder content
that can produce carbon dioxide gassing pin holes in the cured finish. Do not reseal part B
containers that have been contaminated with moisture.
System Mixing and Application
1.4 gallon unit applied at typical 80 sq ft/ unit (30 wet mils)
Surface Preparation:
Shot blasting or coarse grit diamond grinding to achieve minimum CSP 3-4 surface profile. Do not apply over visibly wet substrate, i.e., no reflective film of water or darkening of concrete.
Mixing:
1.4 gallon unit: Single Pack jug set of Base A and Hardener B, one bag of #3100 Filler, one pigment
pack (optional).
Add Base A to mixing vessel. Add Pigment Pack (optional) and mix with slow-medium speed drill and
jiffy mixer until all the powder is well dispersed for 20 seconds. Add Filler C and mix for 1
minute, ensuring all filler has been fully dispersed. This will require scraping powders from the
sides of the mixing pail and remixing until lump free. Finally, add Hardener B and mix for 30
seconds.
Application
Product #3100 should be applied evenly in a consistent layer thickness. Apply the material
immediately after mixing by pouring out in strips and spread using a 30 mil Easy Squeegee or
similar spreading tool and back roll with a looped roller as needed to even out the material.
Proceed immediately with broadcast.
Alternate procedure:
Apply a scratch coat of 6-10 mils, allow to cure minimum 8 hours at 70F. Apply body coat at 12-30
mils, proceed immediately with broadcast. Contact Epoxy Systems, Inc. to verify approved
minimum thickness of the 2nd body coat, which may vary depending on project details and type of
flooring system to be installed. Broadcast application: Immediately after spreading/back rolling
while the Product #3100 is still wet, broadcast to refusal with 30-40 mesh or finer grade sand.
Allow to cure minimum 8 hours at 70F or overnight. Sweep up and vacuum thoroughly all excess
broadcast sand to remove all non-bonded and poorly adhered sand. Note: The sand broadcast is
required unless otherwise approved by Epoxy Systems, Inc.
Application Temperature
The recommended substrate temperature is 60° - 80°F, but no less than 50°F. Temperature greater than 80° F will reduce
working time significantly. The temperature of the substrate should exceed the “dew point” by 5°F during
application and hardening. Temperatures should not fall below 40°F in the 24 hours after application
Working Time
Mixed product should be immediately poured out in strips, spread and broadcasted within 10 minutes at temperature
of 70°F and 50% RH. Higher temperatures and RH will decrease working time.
Do not delay broadcasting of sand—do so immediately after spreading material.
Curing Time (at 70°F, 50% RH)
Tack free after 6-8 hours, flooring system can be installed after 8 hours. No maximum overcoat time with a broadcast texture.
Cleaning of Tools
Clean immediately after use in solvent, e.g., acetone or denatured alcohol.
Storage
Storage temperature between 45°-90°F 12 months in unopened packs for Components A and B, 6 months
for unopened packs of Component C. Protect from weather and moisture / contaminant ingres.
