Liquid flashing can solve a lot of problems on the roof; from irregularly-shaped and hard to flash penetrations; to creating tie-ins without impeding the flow of water. However, it can also be difficult to apply and use if not done correctly.
By following these simple tips and guidelines, your experience working with LIQUISEAL® Liquid Flashing should go smoothly:
- LIQUISEAL Liquid Flashing is incredibly durable, but it won’t adhere properly if the surface isn’t prepared. Always use the tables on LF-A, B, & C to determine what preparation is needed for a given substrate. Here are some examples for common surfaces:
- Metal: Grind clean to expose bare steel or aluminum and create a rough surface before priming. Don’t use a wire brush. Then apply LIQUISEAL Liquid Flashing Metal Primer and allow the primer to cure (this may take several hours).
- EPDM: Scuff the membrane using 60 grit sandpaper and clean with Weathered Membrane Cleaner. After this is done, apply LIQUISEAL Liquid Flashing Metal Primer and allow the primer to cure (this may take several hours).
- TPO: Clean TPO with Weathered Membrane Cleaner (do not scuff with sand paper the way you would other membranes) and apply Versico’s TPO Primer. Allow the primer to flash off.
- PVC & KEE: Scuff the membrane using 60 grit sandpaper and clean with PVC cleaner. No primer is needed prior to application on PVC or KEE membranes.
- Always pre-cut and dry-fit your reinforcing fleece before mixing the resin. LIQUISEAL Liquid Flashing Resin has a "pot-life" of about 20-30 minutes once mixed, so prioritizing time is key.
- By taking the time to watch this flashing video or this tie-in video, review the installation instructions on the Versico website, and reviewing details before using LIQUISEAL Liquid Flashing, you will improve your experience with liquid flashing. A little bit of time spent reviewing these can save you a considerable amount of time on the roof, and prevent the potential waste of product.
