Hot Air Gun Patching
Hot air gun patching is the preferred method because it provides the most durable, permanent repair
possible.
Tools and materials required:
•
Patches
•
Plastic hand-held roller
•
Hot air gun with wide surface nozzle
•
Isopropyl alcohol
•
Scissors
WARNING
It is extremely dangerous to use a hot air gun in the presence of flammable fumes such as gasoline or
paint thinner. There is a high risk of explosion and/or burns.
The procedure for hot air patching is as follows:
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 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.
CAUTION
Injury, especially to hands and fingers, can occur when using a hot air gun. Most welding will occur at
temperatures of 800-1000 °F. Wear gloves to protect skin from overheating, burning and blistering.
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.
