Product Description: VAPORTIGHT COAT®-SG2 is a unique 2-component, alkali resistant, moisture tolerant, extremely high density and chemically enhanced epoxy based product which prevents capillary infiltration of oil and other chemicals from the ground. Applied in one coat, SG2 reduces the passage of water vapor and moisture through slabs and walls, thus eliminating delamination of adhesives, floor coverings and coatings.

Typical Applications: • Indoor and outdoor, new and existing concrete slabs: on grade, above grade, below grade and split slabs. • Oil and other chemically contaminated slabs. • Industrial/retail facilities, office buildings, hospitals and schools, food processing plants, secondary containment slabs, etc. Advantages: • Low VOC and meets USDA/FSIS guidelines • High chemical and alkalinity (pH 14) resistance • Barrier against radon & other gases • Excellent adhesion to steel • Compatible with most flooring systems • Minimal downtime - flooring system installed next day • Does not support mold growth • Protects non-breathable floor coverings/coatings from water vapor transmission through concrete substrates. • Full broadcast system - provides excellent substrate for bonding • Seals oil contaminated slabs • For slabs with MVER up to 25 lbs and RH up to 100% • Can be applied to 5 day old concrete and damp concrete slabs Testing Concrete Slabs for Contaminants: Aquafin recommends testing slabs with unknown history, as well as slabs with previously failed flooring systems, for contaminants (i.e. hydrocarbons, other organic compounds, un-reacted water soluble silicates, chlorides, ASR, Sulfurous compounds, etc.) to determine suitability of SG2. Provide Ion Chromatography and IR Spectroscopy data to Aquafin before commencing application. A separation screed may be required.

rate (MVER) including “Anhydrous Calcium Chloride” testing as per ASTM F 1869-11 on slabs to be treated, to determine the MVER in lb/1000 ft2•24 hrs (grams/m2•hr) and to determine RH content (%) as per ASTM F 2170. This testing can be used to determine application rate of material required to obtain AQUAFIN warranty. Substrate Preparation: •C oncrete must be a minimum 5 days old or have reached a minimum 2,500 psi (17 MPa) compressive strength, to be treated with SG2. Concrete must be clean, sound and have an “open“/absorptive surface (“tooth and suction”). All slabs must be mechanically prepared (i.e. Shot blast) to a concrete surface profile (CSP) 3 – 5 per the International Concrete Repair Institute (ICRI) Guideline No. 301-2R-2013. Acid etching is not allowed, broom finish on new slabs is not acceptable. Burn off any Page 1 of 3

VAPORTIGHT COAT®-SG2 reinforcing fibers and vacuum remains. • After surface preparation, check slab surface with the water drop method. Pour a drop of water about the size of a dime in several places. If the water beads, the surface is not absorptive and requires additional preparation or core extraction and testing. If the water “wets out” or penetrates the concrete within 30 - 60 seconds the surface is ready to receive the SG2 treatment. Note: This method does not replace pre-testing of concrete cores. A test application is highly recommended on existing slabs to determine adhesion (i.e. Elcometer, etc.). • Treat saw cut and expansion joints as per drawings on page 3. Separation Screed: Concrete floors which contain water soluble, unreacted sodium and/or potassium silicates or chlorides can not be coated when certain thresholds of these compounds are exceeded. If these soluble mediums have deeper penetration into the substrate than standard steel shot blasting will remove, it will be required to remove 3/8“ - 1/2“ (10 mm - 13 mm)of the concrete surface and replace it with a separation screed, such as MORTAR-Screed to prevent substrate failure when trapped rising moisture activates these mediums. SG2 will then be applied over the separation screed. All separation screed surfaces must be mechanically prepared like a concrete surface (CSP 3 - 5) as indicated above.
Oil contaminated slabs: Citrus based degreasing agents are recommended for hydrocarbon contaminated slabs containing low to medium amounts of oil. If the IR analysis reveals high concentrations of hydrocarbons then microbial remediation is required. We strongly recommend carrying out a test application of SG2 for both remediation processes, prior to installation of SG2. • De-greasing: After steel shot blasting, treat surface with a degreasing cleaning agent by the “Detergent Scrubbing” method as outlined in ICRI Guideline No. 310.2R-2013. Multiple cleaning cycles may be required. Dispose of the oily wastewater in accordance with federal, state and local regulations. •M icrobial remediation: Follow microbial product manufacturer’s instructions regarding application of microbes or “bugs”. 1. After de-greasing or microbial remediation, clean treated surface with high pressure water blasting (minimum 2,500 psi). 2. The surface shall be damp/moist without standing water, when applying SG2. If the substrate dries before applying SG2, oil can rise again and prevent SG2 from bonding. Water-Vapor Transmission Treatment: 1. Remove existing floor coverings, coatings, adhesives, curing compounds, efflorescence, dust, grease, laitance, etc. down to bare concrete with steel shot blasting, scarifying or grinding using a diamond cup blade (run with low RPM and assure that surface is profiled). 2. Repair cracks with a suitable patching mortar or SG2 mixed with 5 parts by volume of oven-dried sand. 3. Install cementitious underlayment’s or leveling mortars on top of SG2. Mixing: SG2 is supplied in the appropriate mixing ratio (Comp-A = resin, Comp-B = hardener). Always mix full units: • Use chemical resistant gloves and goggles when mixing or applying SG2.

• Material should be min. 60°F (15°C) at time of mixing. 1. Pierce a hole through the rubber membrane in the lid and continue through the bottom of “lid well”. Assure that Part B completely drains into Part A. 2. Stir mixture for approx. 5 minutes to a homogenous, streak free consistency, using a slow speed drill (approx. 300 rpm) with a PS Jiffy blade. Avoid entrapping air. Ensure that the material at the bottom and sides are scraped and thoroughly mixed. 3. Pour mixed material from the mixing container into another, clean container and carefully mix for additional 30 seconds. Application: • Substrate and ambient temperatures must be between 45°F (8°C) and 95°F (35°C). • All exterior applications must be protected from strong sun light, wind and rain until fully cured. All interior applications must be protected from drafts to avoid “skinning over” before sand broadcast. • Application equipment needed: Clean mixing containers, softedge squeegee, non-shed synthetic roller, long handled scrub brush.
1. All surfaces must be saturated surface dry (SSD) with no standing water. 2. P our SG2 in sufficient quantity over the area to be treated (refer to “Application Rates” chart) and uniformly distribute with a 3/16” to 1/4” (4.5 mm to 6 mm) notched squeegee or nonshed 3/8” nap roller to the SSD substrate 3. C arefully scrub material into the substrate with a long handled scrub brush. 4. F ollow with a non-shed roller to achieve uniform coverage. 5. Immediately (within 2 minutes) broadcast clean, oven dried #20 - 50 silica sand (ASTM E11 No. 18 - 35 sieve size [0.5 - 1.0 mm dia.]) to “rejection” (full broadcast), or at a rate up to 30 50 lb/100ft2 (1.5 kg/m2) into the fresh (wet) SG2. 6. Allow
to cure min. 12 hours before removing all excess sand. 7. Immediately clean all equipment and tools with mineral spirits. Flooring • If the flooring system requires a primer over concrete, it should also be used over the broadcasted SG2. • Water or solvent based adhesives may require a cementitious underlayment (see Aquafin LEVEL-Ultra TDS) of a minimum 1/8” (3 mm) thickness to absorb excess moisture/solvent (check with adhesive manufacturer). • Pressure sensitive adhesives installed directly over SG2 require a longer “tack” time than listed on manufacturer’s literature to prevent adhesive moisture or solvent entrapment. • Many flooring systems require a more level or smooth surface. In such cases an application of a self-leveling cementitious underlayment (minimum 1/8” (3 mm) thickness) is required to provide a proper substrate for the floor covering and the adhesive (See Aquafin LEVEL-Ultra TDS). Underlayment’s and Patching: If cement based toppings, such as underlayments, screeds, “flash” patching, repair mortars are to be used, the manufacturer’s recommended primer or SLU-PRIMER must be applied over SG2.
