Hot Air Gun Procedure
1.
In a well-ventilated location, clean the area to be
repaired as well as one side of the patch with an
abrasive pad. Wipe down the repair area and patch
with isopropyl alcohol.
2.
Mount a wide surface air nozzle on the hot air gun so
as to direct the heat flow in a large pattern. Turn the
power on, adjust the temperature in the low range first
and let the hot air gun warm up. Increase the
temperature as required during the operation.
DO
NOT OVERHEAT OR BLACKEN THE FABRIC.
3.
Starting from the centre of the patch (held down by the roller),
concentrate the heat flow equally to patch and fabric. Apply a
light pressure with the roller when the fabric starts melting.
This can be seen as small bubbles.
DO NOT OVERHEAT.
4.
Roll the patch down to fuse it to the fabric, moving roller and
gun simultaneously. Repeat on the unfused portion of the
patch. Let the repaired area cool down. Attempt to peel off at
the edges with your fingers. If there is even a slight peel, repeat
the operation locally. Otherwise, the repair is finished.
Caution
Overheating can occur quickly and can damage the product. It’s recommended that you test, using
the supplied fabric samples, to determine the correct temperature to be used and the duration of
heat to be applied.
