Seal Trust™ Patch Disks are uncured roofing membrane available in black or white with butyl mastic sealer die cut into 8” round disks. Can be used for flashing corners, as repair patches, or t-patches and anywhere required on EPDM, most TPO and some PVC membranes. Membrane must be cleaned prior to installation using Tape Primer.
TPO Patch Disks are a multi use product used in inside/outside corners, t-joint covers, and patching or repairs of both EPDM and TPO membranes. Always clean and prime membrane using roofing industry standard products for tape applications such as Seal Trust Tack Back™ Primer or Low VOC Tape Primer. Lap Caulk should be used around all the outer edges of the disk for proper application. Use 3” steel roller for final installation step. Be careful to avoid fish mouths or air bubbles.
