The desired thickness of membrane coverage is 120 mils for inside\/outside corners and non-moving and hairline cracks, as well as around drains and penetrations.<\/p>\n<p><strong>Footing Details \u2026<\/strong> Use DETAIL STRIP from W.

Material is then ready to install as 114.3 mm (4.5\u201d) strips on either side of the rebar. Any excess can be turned down on the face of the footing. Next, fill the voids around rebars in the keyway with <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/bem-canada\/\">BEM<\/a> from W. R. MEADOWS.\u00a0 Pour the walls.

Extend the material 114.3 mm (4.5)\u201d beyond outside corners. Slit extended portion of DETAIL STRIP lengthwise. Place the horizontal flap out onto the footing and bend the vertical flap around the wall.

R. MEADOWS. CURE-IT is ready to use, no dilution required. \u00a0Using proper dual component spray setup and application methods outlined in the Sprayer Equipment Guidelines for W. R. MEADOWS Co-Spray Fluid-Applied Membranes, spray product onto wall surfaces, holding the gun approximately 508 &#8211; 609.6 mm (20&#8243; &#8211; 24&#8243;) from the surface. Spray apply MEADOW-PRUF CO-SPRAY onto wall surfaces, holding the gun square to the surface and using a cross-hatch pattern to apply an even coat.\u00a0 Minimum wet mil thickness achieved in a single coat shall be 65 mils.<\/p>\n<p>Recommended tip sizes for co-spray and one-part spray application: Graco XHD 551.<\/p>\n<p>In cooler temperatures, &lt;4.4\u00b0 C, condition MEADOW-PRUF CO-SPRAY to a minimum 10\u00b0 C by storing overnight at 23.9\u00b0 C or higher prior to application.\u00a0 Use a heated trailer drum heater and a heat exchanger to keep the product in drums and lines warm (ideally above 21.1\u00b0 C) during spraying in cold conditions. Properly conditioned product sprays, builds, and cures more consistently than cold product, thereby avoiding potential jobsite issues due to rain, snow, frost, or freezing conditions.\u00a0 Ensure that the substrate to be applied is free of frost, ice, or dew.<\/p>\n<p>Frequently inspect surface area with a wet mil gauge as work progresses to ensure consistent thickness and adherence to minimum application thickness specified for project.\u00a0 Porous substrates such as CMU walls may require additional coats to obtain desired thickness.\u00a0 Provide complete coverage over surfaces, so that there are no voids, pinholes or similar passages through membrane.<\/p>\n<p><strong>Repairing Damage Membrane \u2026 <\/strong>Remove damaged and loosely-adhered MEADOW-PRUF CO-SPRAY.\u00a0 Clean weathered or dirty surfaces with a rag dampened with xylene in a 76.2 mm (3\u201d) radius, extending out from the edges of the defect.\u00a0 Follow all safety recommendations of the solvent manufacturer prior to use of any solvents.\u00a0 Do not apply solvent directly to membrane.\u00a0 After wiping surface clean with the dampened rag, allow the surface of the membrane to dry.\u00a0 Re-apply MEADOW-PRUF CO-SPRAY over the cleaned area extending 76.2 mm (3\u201d) from edge of defect.<\/p>\n<p><strong>Curing and Drying \u2026 <\/strong>Curing times will be affected by dew point, relative humidity, temperature, and airflow.\u00a0 If dew point is within 5\u00b0 F of ambient air temperature at time of application, dry time will be drastically increased.\u00a0 The following dry times are given for average conditions and standard thicknesses. Actual times may differ, depending on specific conditions present on job at time of application and curing.<\/p>\n<p><strong>Co-Spray Application<\/strong><\/p>\n<p>Firm Set: \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 &lt;5 minutes at 23.9\u00b0 C and 50 RH<br \/>\nDry Film: \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 12 hours at 23.9\u00b0 C and 50 RH<\/p>\n<p>Allow the membrane to dry completely before subjecting it to inspection for air\/water leakage and adhesion testing. Drying time varies with substrate, ambient temperature and humidity. Membrane is dry when it appears black and rubber-like, and feels dry when pressed. It is recommended that MEADOW-PRUF CO-SPRAY be allowed to air dry to a tack-free film before application of specified insulation.\u00a0 High ambient air and surface temperature will affect cohesive and adhesion properties during testing.<\/p>\n<p><strong>Compatibility \u2026<\/strong> Prior to project start, during the initial walk through identify all membranes, coatings, sealants, tapes and joint compounds by others which will contact MEADOW-PRUF CO-SPRAY and any accessories products.\u00a0 W. R. MEADOWS offers a complete air\/vapor and waterproofing building envelope enclosure system and should be used when possible since compatibility and functionality have already been verified.\u00a0 If not possible to use W. R. MEADOWS system products, verify compatibility with W. R. MEADOWS and the other\u2019s material manufacturer prior to installation.\u00a0 Laboratory verification of compatibility can take up to six weeks.<\/p>\n<p>MEADOW-PRUF CO-SPRAY is not compatible with most polyurethanes, soft PVC, or silicones.<\/p>\n<p>Please reference W.
