Provide Ion Chromatography and IR Spectroscopy, and <br />where necessary ASR data to Aquafin before commencing application. <br />A separation screed may be required. See Separation Screed section for <br />more information. <br />Concrete Moisture Testing: <br />Aquafin recommends moisture testing of all concrete slabs. However, <br />moisture testing is only a guideline and can be influenced by environmental <br />factors. <br />• Interior Concrete Slabs: Aquafin recommends testing to determine <br />moisture vapor emission rate (MVER) including “Anhydrous Calcium <br />Chloride” testing as per ASTM F 1869-11 on slabs to be treated, to <br />determine the MVER in lb/1000 ft2•24 hrs (grams/m2•hr) and to <br />determine RH content (%) as per ASTM F 2170. <br />• Exterior Concrete Slabs: To obtain an approximate measurement of <br />the moisture in exterior concrete slabs, Aquafin recommends using a <br />combination of in-situ RH content (%) testing and surface MC (%) testing <br />and then comparing the results. <br />Substrate Preparation: <br />• Concrete must be a minimum 5 days old or have reached a minimum <br />2,500 psi (17 MPa) compressive strength, to be treated with <br />VAPORTIGHT COAT®-SG3. Concrete must be clean, sound and have <br />an “open“/absorptive surface (“tooth and suction”). All concrete must <br />be mechanically prepared (i.e. Steel shot blast) to a concrete surface <br />profile (CSP) 3 – 5 per the International Concrete Repair Institute (ICRI) <br />Guideline No. 301-2R-2013. Acid etching is not allowed, broom finish <br />on new concrete is not acceptable. Burn off any reinforcing fibers and <br />vacuum remains. <br />• Remove glaze from “quarry tiles”. <br />• After mechanical preparation, check the porosity of the concrete surface <br />using the water drop test method (ASTM F3191). Beading water drops <br />signal a non-absorptive condition. Additional profiling will be necessary <br />until all contaminants are removed, and the water drop test verifies <br />an absorptive, porous concrete surface. If additional profiling does <br />not remedy the non-absorptive condition, contact Aquafin’s Technical <br />Department. <br />Note: Concrete core sample analysis can be very beneficial in this <br />scenario, as it will pinpoint the depth of contaminants in the concrete <br />and estimate how much of the surface will need to be removed to <br />achieve the requirement of a contaminant-free, porous concrete surface. <br />Mock-up: <br />Aquafin recommends installation of a field sample of min. 100 ft² at <br />the project site or other pre-selected area as agreed to by owner’s <br />representative and applicator. <br />• Apply all materials to field sample area in the correct layering <br />sequence. Include all layers and materials that will be used in <br />the application (screeds, patching compounds, membranes, <br />coatings, roof systems, underlayments, adhesives, flooring, <br />etc.). Follow all manufacturer’s written instructions. <br />• Maintain field sample during construction for workmanship <br />comparison. Use field sample as standard for judging <br />aesthetics on remainder of project. Do not alter, move, or <br />destroy field sample until work is completed and approved by <br />owner’s representative. <br />• Mock-ups are also recommended for adhesion testing to <br />confirm compatibility with all materials being used in the <br />application, and also to better define recoat times based on <br />actual jobsite conditions. <br />Crack and Joint Treatment: <br />Pre-treat all saw cut joints, expansion joints, and cracks 1/8” and wider. <br />Check our website for the latest version of the Technical Datasheet. <br />www.aquafin.net</p> <p>Refer to drawings on page 4 for saw cut joint and expansion joint <br />treatment. <br />• Cracks 1/8” and Wider: Fill cracks 1/8” and wider with VAPORTIGHT <br />COAT®-SG3 mixed with 5 parts by volume of oven-dried sand. Apply <br />the VAPORTIGHT COAT®-SG3 field coat over crack areas as soon as <br />VAPORTIGHT COAT®-SG3 with sand mixture has reached its initial set. <br />• Cracks Less Than 1/8” Wide: Fill cracks less than 1/8” wide with <br />VAPORTIGHT COAT®-SG3 neat. <br />Separation Screed: <br />Concrete floors which contain water soluble, unreacted sodium and/or <br />potassium silicates or chlorides cannot be coated when certain thresholds <br />of these compounds are exceeded. If these soluble mediums have deeper <br />penetration into the substrate than standard steel shot blasting will remove, <br />it will be required to remove 3/8“ - 1/2“ (10 mm - 13 mm) of the concrete <br />surface and replace it with a separation screed, such as MORTAR-Screed <br />CI, to prevent substrate failure when trapped rising moisture activates <br />these mediums. VAPORTIGHT COAT®-SG3 will then be applied over the <br />separation screed. All separation screed surfaces must be mechanically <br />prepared like a concrete surface (CSP 3 - 5) as indicated above. <br />Vertical Applications (Walls): <br />Note: Wall Projects require pre-approval from Aquafin Technical Services <br />prior to application of VAPORTIGHT COAT®-SG3 in order to qualify for <br />any type of warranty. <br />1. Apply the first coat of VAPORTIGHT COAT®-SG3. <br />2. Apply the second coat of VAPORTIGHT COAT®-SG3 “fresh-in-fresh” <br />(green-on-green) as soon as the first coat has adhered and is firm enough <br />to receive the second coat without displacement. Check the mil thickness of <br />the second coat and each subsequent coat using a wet film gauge. <br />3. Repeat with additional coats of VAPORTIGHT COAT®-SG3 as needed <br />to meet the required total mil thickness. <br />Mixing: <br />VAPORTIGHT COAT®-SG3 is supplied in the appropriate mixing ratio <br />(Comp-A = resin, Comp-B = hardener). Always mix full units. <br />• Use chemical resistant gloves and goggles when mixing or applying <br />VAPORTIGHT COAT®-SG3. <br />• Epoxy-based coatings are temperature sensitive and care should be <br />taken to condition all components to between 65°F to 75°F (18°C to <br />24°C) prior to mixing and placement. <br />1. For 0.24 and 2.4 gal kits only (7.3 gal kit packaged separate A&B <br />containers!): Pierce a hole through the rubber membrane in the lid and <br />continue through the bottom of “lid well”. <br />Assure Part B completely drains into Part A. <br />2. Stir mixture for approx. 5 minutes to a <br />homogenous, streak free consistency, using <br />a slow speed drill (~300 rpm) with a PS Jiffy <br />blade. Avoid entrapping air. Ensure that the <br />Comp B <br />material at the bottom and sides are scraped <br />and thoroughly mixed. <br />3. Pour mixed material from the mixing container <br />into another, clean container and carefully mix <br />Comp A <br />for additional 30 seconds. <br />Application: <br />Read all instructions thoroughly prior <br />to installation. <br />• Substrate and ambient temperatures must be at least 45°F (8°C) and <br />rising and no higher than 95°F (35°C). <br />• All exterior applications must be protected from strong sun light, wind <br />and rain until fully cured. <br />Page 2 of 4</p> <p>(updated 12/20/22-EK/VB/AC)</p> <p>VAPORTIGHT COAT®-SG3 <br />• All interior applications must be protected from drafts to avoid “skinning <br />over”. <br />• VAPORTIGHT COAT®-SG3 surface must be protected from bond <br />inhibiting contaminants, i.e. dirt, dust and debris. <br />• Application equipment needed: Clean mixing containers, soft-edge <br />squeegee, non-shed synthetic roller. <br />1. A <br /> ll surfaces must be saturated surface dry (SSD) with no standing water. <br />2. Pour VAPORTIGHT COAT®-SG3 in sufficient quantity over the area to <br />be treated and uniformly distribute with a notched squeegee. <br />3. Follow with a non-shed roller, back rolling at right angle (90 degrees) <br />to the squeegee application to achieve uniform coverage. Always <br />verify that the proper mil thickness has been achieved by measuring the <br />coating using a wet film gauge. As a minimum, it is recommended to <br />check the mil thickness in every corner, plus the center area of the room. <br />Large areas may require additional check points. <br />Curing: <br />• Allow to cure for minimum 12 hours [based on 73°F (23°C)]. <br />Notes: Mix VAPORTIGHT COAT®-SG3 with VAPORTIGHT COAT <br />ACCELERATOR when faster curing times are desired. Refer to <br />VAPORTIGHT COAT ACCELERATOR Technical Data Sheet for more <br />information. <br />• Once VAPORTIGHT COAT®-SG3 has completely dried, inspect the <br />surface for imperfections and voids such as “outgassing channels”, and <br />pinholes. These areas will need to be re-treated. <br />• P repare areas to be retreated by first sanding the surface and then <br />cleaning with hot water. Allow all areas to dry completely. <br />• Reapply VAPORTIGHT COAT®-SG3 over areas that need retreating <br />within 5 days after the first coat for interior applications, and within 48 <br />hours after the first coat for exterior applications. Please contact Aquafin <br />Technical if recoat time cannot be met. <br />• Coatings Systems over VAPORTIGHT COAT®-SG3: VAPORTIGHT <br />COAT®-SG3 provides a suitable substrate for many different types <br />of coating systems, including but not limited to: interior floor coatings, <br />interior/exterior pedestrian traffic coatings, vehicle traffic membranes, <br />and roof coating systems.

Actual coverage may vary due to absorption of substrate. Coverage rates for wall applications include a waste factor due to <br />expected loss of material. Failure to achieve the required mil thickness will compromise the effectiveness of the product and void the warranty. It is the applicator’s responsibility to verify that the <br />required mil thickness has been attained. <br />AQUAFIN, INC. 505 Blue Ball Rd., #160 Elkton, MD 21921 <br />Phone: (410) 392-2300 FAX: (410) 392-2324 htpp://www.aquafin.net</p> <p>Sample Water Vapor Transmission Reduction <br />Test carried out by independent <br />laboratory (Wet method) <br />Water Vapor Transmission: <br />• lbs/1000 ft2 * 24 hrs <br />Vapor Permeance: <br />grains/hour/ft2/in.Hg</p> <p>Test : ASTM E 96</p> <p>BEFORE: <br />Untreated Control</p> <p>AFTER: <br />VAPORTIGHT COAT®-SG3</p> <p>24.08</p> <p>Sample A, No.1 <br />0.18 (Mactec, 3/17/06)</p> <p>REDUCTION <br />99%</p> <p>0.10 @ 16 mils <br />(Nelson Testing, 01/08/14)</p> <p>ASTM F3010-13</p> <p>3.17</p> <p>Check our website for the latest version of the Technical Datasheet.
