Perma-Pool Patch for Concrete Pools Pool Patch is a fast setting, high strength patching and repair mortar that may be used above or below water levels. Pool Patch can be used in pools, concrete holding tanks, concrete pipe or virtually anywhere concrete repairs are needed. Features: Concrete pool patch Can be used above or below water levels Stops the loss of water Rapid setting Easy to mix Can be colored to match existing substrates Excellent bonding properties Waterproof Chloride and metal free mortar Freeze-Thaw stable Can be shaved and molded to desired contour Once set, Pool Patch is resistant to hydrostatic pressure Substrate Preparation: Underwater: Wire brush area of repair to remove loose or flaking. When possible, undercut the repair area to insure the best results. Above Water Level: Undercut the substrate and open the crack or hole to a minimum depth and width of 1". Wire brush and then flush away all loose material. Remove all oil, grease, dirt and other contaminates to expose clean sound concrete. All traces of oil, dirt or grease must be removed by scrubbing with an industrial detergent. After scrubbing, flush thoroughly with clean water. The substrate surface must be SSD (Saturated Surface Dry) prior to application. NOTE: Do not apply to frozen substrates or where ambient temperatures are below 35 degrees. MIXING: Mix Pool Patch with clean potable water. Add just enough to make a putty consistency. Water ratio is 3 parts powder to 1 part water. Pool Patch is to be mixed in small quantities due to rapid set time. Underwater: Mixing in a small pail, take Pool Patch in gloved hand and hold until material starts to firm up. Then, immediately press into hole or crack. Hold for 1 minute, longer if needed, until Pool Patch has set up. Repeat procedure until crack has been filled. Pool Patch may be shaved flush with the side of the pool once initial set has occurred. Above Water Level: Mix sufficient material to complete repair, but not more than can be placed in 10 minutes. Place by trowel into properly prepared surface and shape to contours of repair area. Areas covered with Pool Patch can be covered with a cementitious coating one hour after the application. Note: Cooler temperatures will increase the pot life an set time of Pool Patch. Warmer Temperatures will decrease them.
