This is how it's done:
Cracks with a length of up to 10 cm can
be repaired without removing the bumper.
If material has broken out of the bumper,
Welding bumpers
the damaged area should be repaired from
both sides.
Drill a hole of approx. 5 mm in diameter at
both ends of the crack to visually mark the
crack ends and prevent further cracking.
Using an angle grinder/milling tool, remove
approx. 1 mm of material over a width of
approx. 20 mm on either side of the crack
to insert the stainless-steel mesh later on.
Using an orbital sander, now sand off the
paint across a width of approx. 40 mm all
the way round the crack.
Fit the heat guard, reduction nozzle and repair
nozzle to the hot-air outlet nozzle. Set the hot
air gun to 650 °C/air flow rate to speed 8 and
save this setting to programme 4. The gun is
ready for use after approx. 3 mins.
While the gun is warming up, cut the stain-
less-steel mesh to size. Dimension: 10 mm
longer than the crack, extending by 20 mm
beyond the crack on either side. Round off
the corners.

Using the plastic repair nozzle, fuse the
stainless-steel mesh into the plastic. First
fix one corner, then heat the mesh all over
and fuse evenly not applying too much
pressure. For this process, always work
in same direction.
Note: The plastic must fully penetrate
the mesh
Now carefully apply the Multi-Thermoflexx
welding rod. Rod and surface must be
evenly heated and completely fuse with the
surface. The welding rod must turn ductile
to produce a proper bond with the plastic
material you are working on. Slowly and
carefully smooth the material at the edges.
Let the material cool down. Now create a
surface for painting.
