- Typical Applications
• Indoor and outdoor, new and existing concrete slabs: on grade, above grade, below grade and split 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.,/p>
- 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.,/p>
- Substrate Preparation
• Concrete must be a minimum 5 days old or have reached a minimum 2,500 psi (17 MPa) compressive strength, to be treated with SG3. 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 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 SG3 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.,/p>
- 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 SG3 mixed with 5 parts by volume of oven-dried sand. 3. Install cementitious underlayment’s or leveling mortars on top of SG3.,/p>
- 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”. • SG3 surface must be protected from bond inhibiting contaminants, i.e. dirt, dust and debris. • Application equipment needed: Clean mixing containers, soft-edge squeegee, non-shed synthetic roller. 1. All surfaces must be saturated surface dry (SSD) with no standing water. 2. Pour SG3 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 12 hours. NOTE: Where sand broadcast is desired use SG2 in lieu of SG3. 4. Re-treat “outgasing channels” and pin-holes by sanding surface, and cleaning with hot water. Make sure surface is dry and re-apply SG3. 5. Immediately clean all equipment and tools with mineral spirits.,/p>
- Maximum Recoat Time
• Interior Applications: Top coatings (i.e. epoxy, terrazzo, urethane) and flooring systems (i.e. VCT, sheet vinyl, carpet, wood) must be applied within 12 hrs - 5 days. • Exterior Applications: Top coatings such as epoxy, urethane traffic membranes, must be applied within 24 hrs - 36 hrs. • If recoat time is missed, SG3 surface must be sanded, cleaned with hot water, and allowed to dry, before application of flooring systems or top coatings.,/p>
- 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 SG3 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 LEVELUltra TDS). • Do not apply flooring system if SG3 surface is wet due to dew point or other causes.,/p>
- 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 SG3.,/p>
- Limitations
• Do not spray apply SG3. • Post-cracking of the concrete, slab warping or warping relaxation at joints or cracks after installation of the SG3 may cause a breach in the coating and void warranty. • Do not apply over gypsum based substrates. • Do not alter mixing ratios, thin or mix with Cab-O-Sil. • Call Aquafin Technical Department for slabs with floor heating systems or installation recommendations for any substrates and conditions not listed.,/p>

Technical Details & Test Data
- 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 SG3. Provide Ion Chromatography and IR Spectroscopy data to Aquafin before commencing application. A separation screed may be required.,/p>
- 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. SG3 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.,/p>
