Product Description: VAPORTIGHT COAT®-SG4 is a rapid setting 2-component, moisture tolerant, low viscosity, solvent free, chemically enhanced epoxy based product which reduces the passage of water vapor and moisture through slabs on, below and above grade as well as split slabs, thus eliminating delamination of adhesives, floor coverings and coatings. SG4 meets or exceeds the requirements of ASTM F3010-13 Standard Practice for Two-Component Resin Based Membrane-Forming Moisture Mitigation Systems for Use Under Resilient Floor Coverings. Typical Applications: • Indoor and outdoor, new and existing concrete slabs: on grade, above grade, below grade and split slabs where a fast turnaround time is desired. • Concrete slabs, old cementitious underlayment (no gypsum) and ceramic tiles with missing or damaged under-slab vapor barriers. • Industrial/retail facilities, office buildings, supermarkets, food processing plants, airplane hangars, hospitals, schools, etc. • Use VAPORTIGHT COAT-SG2 for capillary infiltration of oil or other chemicals from the ground or to treat oil-contaminated slabs or radon infiltration. Advantages: • One coat system - No sand broadcast • Low viscosity, solvent free, no VOC’s • For slabs with MVER up to 25 lbs and RH up to 100% • ASTM E 96 perm rating ≤0.10 • Flooring system installed same day • Can be applied to damp & green concrete (min. 5 days old) • High alkalinity barrier (pH 14) • Compatible with most flooring systems • Does not support mold growth • Great for indoor applications: low odor and non-flammable. • SG4 passed Indoor Air Quality Material Emissions Test as per DIN EN ISO 16000 (Report CT-10-06-22-01:250005/2-3) 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 Check our website for the latest version of the Technical Datasheet. www.aquafin.net

determine suitability of SG4. Provide Ion Chromatography and IR Spectroscopy data to Aquafin before commencing application. A separation screed may be required. Moisture Vapor Emission Testing: Aquafin recommends testing to determine moisture vapor emission 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 SG4. Concrete must be clean, sound and have Page 1 of 3

VAPORTIGHT COAT®-SG4 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 reinforcing fibers and vacuum remains. • Remove glaze from “quarry tiles”. • 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 SG4 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 back. 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. SG4 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. 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 SG4 mixed with 5 parts by volume of oven-dried sand. 3. Install cementitious underlayment’s or leveling mortars on top of SG4. Mixing: SG4 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 SG4. • Material should be minimum 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 (~300 rpm) with a PS Jiffy blade. Avoid entrapping air. Ensure that the material at the bottom and sides Comp B are scraped and thoroughly mixed. 3. Pour mixed material from the mixing container into another, clean container and Comp A carefully mix for additional 30 seconds.

Application: • Substrate and ambient temperatures must be between 40°F and 85°F (5°C to 30°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”. • SG4 surface must be protected from bond inhibiting contaminants, i.e. dirt, dust and debris. • Application equipment needed: Clean mixing containers, softedge squeegee, non-shed synthetic roller. 1. All surfaces must be saturated surface dry (SSD) with no standing water. 2. Pour SG4 in sufficient quantity over the area to be treated and uniformly distribute with a notched squeegee. 3. Follow with a non-shed roller, back rolling at right angle (90 degrees) to the squeegee application to achieve uniform coverage and let product cure for minimum 3.5 hours. NOTE: Where sand broadcast is desired use SG2 in lieu of SG4. 4. Re-treat “outgasing channels” and pin-holes by sanding surface, and cleaning with hot water. Make sure surface is dry and reapply SG4. 5. Immediately clean all equipment and tools with mineral spirits. Maximum recoat time: • Interior Applications: Top coatings (i.e. epoxy, terrazzo, urethane) and flooring systems (i.e. VCT, sheet vinyl, carpet, wood) can be applied after 3.5 hours. Observe dew point! • Exterior Applications: Top coatings such as epoxy, urethane traffic membranes, must be applied within 24 hrs. Observe dew point! • If recoat time is missed, SG4 surface must be sanded, cleaned with hot water, and allowed to dry, before application of flooring systems or top coatings. Flooring • 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 SG4 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). • Do not apply flooring system if SG4 surface is wet due to dew point or other causes. 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 Aquafin SLU-PRIMER must be applied over SG4. Packaging and Shelf Life: Shelf life is 2 years in closed, original packaging, stored in a dry, cool place. Standard Packaging: • 1.46 gal/13.2 lb (5.5 L/6 kg) kit.
