Procedure to Repair Voids in Hot Air Welded Seams
Prepare the surface by removing debris, contaminants and ballast from
the area of the membrane or flashing to be repaired. The area should
extend beyond the perimeter of the void to provide an ample-sized
clean work area. Check all hot air welded seams for voids with a Flex
seam probe. When a void is found open the seam until a fully welded
seam area is determined. Scrub the repair area clean with an approved
cleaner being sure to clean both the upper and lower surfaces of the
seam.
Dry the repair area with a rubber squeegee and clean, absorbent,
lint –free cloths. Wipe the area of the bottom membrane and the
underside of the upper selvedge edge membrane with a clean,
absorbent, lint-free cloth dampened with a solvent such as Flex
Weathered Membrane Cleaner. Do not pour the solvent directly on the
membrane. Wipe the repair area clean and allow the area to air dry.
Pre-weld the seam by inserting the hot air nozzle into the seam and
forming a continuous pre-weld approximately 2 inches from the outer
edge of the selvedge edge. Finish weld the outer 2 inches of the seam
pressing firmly with the rubber faced hand roller. Allow the welded area
to cool to ambient temperature and check the welded seam for voids
using a seam probe. If voids are found, re-weld with the hot air welder
and recheck with the seam probe.
