Installation Tips for QA Uncured Flashing Products
Read This Post
STORAGE: Heat exposure is what causes Quick-Applied (QA) Uncured Flashing to cure on the roof after installation, so storing all your QA Uncured Flashing in a cool place will maximize its shelf life. Versico performed an experiment where Peel and Stick (P&S) White EPDM Corners were refrigerated for 18 months and they were still uncured and usable. Pretty "cool" for a product with a 6-month shelf life!
HEAT: Want to make your QA Uncured Flashing easier to work with? Use a heat gun to warm the flashing prior to installation in colder weather. Always heat P&S White Uncured EPDM Flashing, even in the warmer months. Rule of thumb; store cool and install warm!
INSTALLATION: Speaking of forming corners, the QA Uncured Flashing stretches and forms better when the elongated diamond pattern is installed parallel to the deck membrane. Additionally, it helps to use the poly film as a separator when folding the corner in half to prevent the exposed tape edges from sticking to each other.
POURABLE SEALER POCKETS: One of the biggest mistakes Versico encounters with Pourable Sealer Pockets is improperly applied or missing primer. It is very important to prime the flashing that is turned down into the pocket, as well as the flashing on the top rim of the pocket. Primer is necessary to achieve a long-term bond between Pourable Sealer and the pocket. If separation is present, it's likely that primer application was missed. It is also important and necessary to thoroughly clean and prime penetrations prior to filling pockets with pourable sealer.
OUTSIDE CORNERS: Double-wrapping outside corners is a great idea on ballasted systems, especially if the base membrane isn't cut perfectly tight to the curb. QA Uncured Flashing needs to have a solid surface beneath it for long-term performance. If an additional layer of QA Uncured Flashing is installed to eliminate voids at outside corners, the corner flashing will be better able to withstand movement from expansion/contraction forces and will be less likely to develop a hole than if a single layer is used.
LAP SEALANT: All QA Uncured Flashing requires Lap Sealant to be applied and feathered over the entire splice edge. Versico has all your flashing needs covered. For more information, please contact your Regional Technical Manager.
