Wet curing is recommended.\u00a0 All membrane curing compounds must be mechanically removed. New concrete should be power washed or blown clean with oil-free compressed air before coating application to ensure removal any dirt build or contaminates that may interfere with bond of primer or HYDRALASTIC 836 SL.<\/p>\n<p><strong>Surface Preparation \u2026<\/strong> HYDRALASTIC 836 SL is intended for concrete, metal, and wood surfaces.\u00a0 For existing concrete remedial work or new concrete lacking profile, lightly roughen or rough grind substrate. Concrete surfaces require a medium sandpaper finish equal to or greater than ICRI CSP #3. Surface preparation may be completed by shot blasting.\u00a0 Install a 9.30 &#8211; 18.58 m<sup>2 <\/sup>(100 &#8211; 200 ft.<sup>2<\/sup>) mockup of the system to be installed and approved for actual coverage rates and functionality before proceeding.<\/p>\n<p>The concrete must be structural sound and free of all contaminates, including oil, grease, dust, laitance, and other bond-breaking materials. Mechanically abrade the concrete surface by grinding, abrasive blasting, or shot blasting to ICRI Guideline No. 310.2R, CSP 3 &#8211; 5.<\/p>\n<p>All surfaces must be thoroughly dry, not damp, and have no standing water to ensure proper performance of the HYDRALASTIC 836 SL system.<\/p>\n<p>For metal surfaces, remove all oils or other contaminants on the surface prior to application of HYDRALASTIC 836 SL.\u00a0 Mechanically abrade and solvent wipe to remove any contaminates.\u00a0 Allow the solvent to evaporate completely prior to application of\u00a0 HYDRALASTIC 836 SL.<\/p>\n<p><strong>Joints, Cracks, and Flashing \u2026 <\/strong>Apply a stripe coat of HYDRALASTIC 836 SL over all cracks up to 1.6 mm (1\/16&#8243;) width. All cracks over 1.6 mm (1\/16&#8243;) width must be caulked.\u00a0 All detailing must be covered within 48 hours at 23\u00b0 C with the full application of the HYDRALASTIC 836 SL waterproofing.<\/p>\n<p><strong>Priming \u2026 <\/strong>For porous substrates and where air and\/or moisture release may cause pinhole or blister problems to occur in the applied membrane, priming the substrate prior to application of HYDRALASTIC 836 SL is recommended.\u00a0 Discovery of these issues is generally revealed in the mockup.\u00a0 For priming recommendations and installation, refer to <a href=\"https:\/\/can.wrmeadows.com\/hydralastic-836-and-sl-priming-installation-guidelines\/\">PRIMING GUIDE<\/a>.<\/p>\n<p><strong>Decrease Blistering \u2026 <\/strong>This is a water-activated waterproofing compound; as such, water is required for proper curing. The waterproofing membrane should be properly mixed with water to achieve optimal performance.\u00a0 Add up to (0.95 L) (1 qt.) of potable water per 18.9 L (5 gal.) pail of HYDRALASTIC 836 SL. Applying HYDRALASTIC 836 SL in the cooling\/declining temperature part of the day or not in direct sunlight will decrease probability of blistering due to outgassing from the concrete and\/or also due to surface sealing rapidly, trapping vapour\/moisture in the material. Do not apply when the surface temperature of the substrate is greater than 32\u00b0 C.<\/p>\n<p><strong>Mixing \u2026<\/strong>. Mix ratio is 20 parts HYDRALASTIC 836 SL to one part water by volume. HYDRALASTIC 836 SL should be thoroughly mixed before adding water.\u00a0 Add up to 0.95 L (1 qt.) of water to 18.9 L (5 gal.) of HYDRALASTIC 836 SL and mix thoroughly for three minutes using a mechanical mixer at slow speed to ensure a homogeneous material. Use a mixing blade designed for paints or coatings, not a mud or mortar mixer.\u00a0 Take care not to allow entrapment of air into the material.<\/p>\n<p><strong>Application Method \u2026<\/strong> Make sure product is conditioned at 23.9\u00b0 C by storing product overnight or at least 12 hours prior to use for ease of application.<\/p>\n<p>Apply evenly by notched squeegee. A serrated or notched squeegee is suggested for best results.\u00a0 Since HYDRALASTIC 836 SL is designed to be self-leveling, the material will level behind the notched squeegee to a given thickness depending on amplitude of notch.\u00a0 This helps to ensure uniform coverage, decreased waste, and ease of application. Following application with a notched rubber squeegee, back roll with a short hair nap roller in a cross direction to ensure a uniform surface. HYDRALASTIC 836 SL can also be applied horizontally with a serrated or notched squeegee. Cure time will vary depending on temperature and humidity. Attention to proper slope to drain is essential for proper waterproofing. HYDRALASTIC 836 SL has a work life of 20 minutes at 23.9\u00b0 C with the addition of potable water.\u00a0 Make sure all spreading and finishing of the product has been completed within this timeframe.<\/p>\n<p>In critical waterproofing applications such as plaza decks, podiums, or other similar horizontal waterproofing applications, a 60-mil layer of HYDRALASTIC 836 SL embedded with <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/reinforcing-fabric-hcr-canada\/\">REINFORCING FABRIC HCR<\/a> from W. R. MEADOWS is recommended.\u00a0 Keep in mind, the reinforcing fabric must be embedded in the wet HYDRALASTIC 836 SL to ensure proper bond and wetting-out.\u00a0 Typically, this must be completely finished within 20 minutes of initial mixing at 23\u00b0 C. For all horizontal installations, refer to <a href=\"https:\/\/can.wrmeadows.com\/technical-bulletins\/hydralastic-836-sl-high-build-reinforced-system\/\">High Build Reinforced System installation guidelines<\/a>\u00a0for proper installation guidelines.\u00a0 If there are no details available for your specific application, please contact a W. R. MEADOWS representative for recommendations.<\/p>\n<p>If a second coat is necessary, apply as soon as first coat has set sufficiently to support subsequent coat. Recoat time at 23.9\u00b0 C and 50% relative humidity is 2 &#8211; 4 hours before proceeding to subsequent coats, but no more than 24 hours apart.\u00a0 As ambient, substrate, and material temperatures increase, an oily-like film may develop on the surface and act as a bond breaker.\u00a0 For next-day or second-coat applications, rub the tie-in area down [152 &#8211; 203 mm (6\u2033 &#8211; 8\u2033)] wide with acetone, mineral spirits, or xylene. This removes the oil film. Do not use alcohol.\u00a0 If more than 48 hours has elapsed at 23\u00b0C), a prime coat of the epoxy primer must be applied per <a href=\"https:\/\/can.wrmeadows.com\/hydralastic-836-and-sl-priming-installation-guidelines\/\">Priming Installation Guideline<\/a>.\u00a0 Primer must be completed to ensure inter-coat adhesion.<\/p>\n<p>HYDRALASTIC 836 SL can be applied up to 15 mils in a single vertical application until the minimum 60 mils or project specified mil thickness requirement is achieved.<\/p>\n<p><strong>Protect the Membrane \u2026<\/strong> Protect HYDRALASTIC 836 SL with <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/mel-drain-canada\/\">MEL-DRAIN<sub>\u2122<\/sub><\/a> (type with the polymeric backing film) from W. R. MEADOWS or contact W. R. MEADOWS for additional protection course options.\u00a0 Application of protection should be done after material can be walked on without causing damage to the integrity of the membrane.<\/p>\n<p>HYDRALASTIC 836 SL will not typically wash off if rain begins during or after application.\u00a0 Stop all work if rain begins and protect open or unused material from rainfall.<\/p>\n<p><strong>Cleanup \u2026<\/strong> Uncured HYDRALASTIC 836 SL cleans up easily with acetone, mineral spirits, or xylene.\u00a0 Cured material is best removed by mechanical means.<\/p>\n<p><strong>PRECAUTIONS<\/strong><\/p>\n<p>Do not expose product to exterior UV for longer than 14 days.\u00a0 HYDRALASTIC 836 SL is not to be used as a liner in a water-containing structure and is not to be used as an exposed or wearing surface.\u00a0 For this purpose, use the <a href=\"https:\/\/can.wrmeadows.com\/cementitious-waterproofing\/\">GEMITE<sub>\u00ae<\/sub> line of products<\/a>.\u00a0 HYDRALASTIC 836 SL is not compatible with asphalt, polymeric-based products, or asphaltic membranes.\u00a0 Do not use on surfaces that are later to be painted.\u00a0 The product cannot withstand direct wear or abrasion.\u00a0 Containers that have been opened must be used as soon as possible.\u00a0 Do not dilute product with solvent under any circumstance. HYDRALASTIC 836 SL is not recommended for use over magnesite, gypsum, lightweight concrete, or where chained or studded tires may be used.
