VaporTight Coat SG2

VAPORTIGHT COAT-SG2 combines an unusually wide variety of advantages in one unique product: moisture barrier
  • Vapor barrier
  • Moisture tolerant
  • High chemical resistance
  • Excellent adhesion to damp substrates
  • Good adhesion after freeze/ thaw cycling
  • Easy to apply - one coat application
  • Functions as negative side waterproofing
  • Provides good bonding for additional top coatings such as adhesives, epoxies and self levelers

Areas of application:
Concrete slabs on or below grade such as

  • Industrial/retail facilities
  • Office buildings
  • Hospitals and schools
  • Residential slabs
Typical applications:
  • Concrete slabs with missing or damaged vapor barriers.
  • Oil contaminated concrete substrates
  • One week old concrete slabs and underlayments
  • New concrete slabs with excessive moisture content to receive a flooring or coating
VAPORTIGHT COAT-SG2 is a unique 2-component, moisture tolerant, extremely high-density epoxy based product, which prevents the passage of water vapor and moisture through slabs on or below grade, thus eliminating delamination of adhesives, floor coverings and coatings. It also prevents capillary infiltration of oil or other chemicals from the ground and can be used to treat oil contaminated slabs.

VAPORTIGHT COAT-SG2 reduces water vapor emission level; of up to 25 lbs//24 hrs - 100 ft2 to 3 lbs or less for the installation of most floor covering systems including VCT, sheet vinyl, carpets, wood, laminates, epoxy, terrazzo & synthetic "SG2" can also be used as a stand-along coating (consult our technical dept.)

Water Vapor Emission Test: Use "Anhydrous Calcium Chloride" testing as per ASTM F 1869-98 to determine the existing water vapor emission rate prior to application of VAPORTIGHT COAT-SG2.

Surface Preparation:
Use steel shot blasting, high-pressure water or abrasive (sand) blasting, scarifying or other suitable means to obtain a uniform, absorptive surface, free of existing coatings or any bond inhibitors. (ICRI CSP 2-3 profile.) Rinse all surfaces to be treated with clean water, leaving no standing water.

Mixing and Application:
Thoroughly mix resin and hardener (component A & B) as per data sheet instructions. Pour and spread product in one coat at a rate of 1 1 5 ff2/gal (2.8 m2/liter) by roller or squeegee to the moist substrate, and carefully scrub it into the pores with a long handled brush. Follow with a roller to achieve a uniform coverage. Protect treated area from strong sunlight and wind. Indoors, prevent noticeable drafts.

Broadcast #20 mesh (0.5-1.0 mm) sand info fresh application.
Installation time: 1 day
