| Definition |
 |
Lifting / wrinkling of
the paint surface. |
| |
|
| Cause |
|
Substrate was not fully
cured or is solvent-sensitive. |
|
Areas where clear coat
was sanded through to base coat were not isolated
or were isolated, but with an unsuitable surfacer. |
|
Unsuitable substrate (e.g.
spray finish with TPA or nitrocellulose paints). |
|
Unsuitable priming materials,
middle coats or reducers were used. |
| |
|
| Prevention |
|
Carry out a solvent test
on problem substrates. |
|
Apply several thin coats
of a 2K surfacer on problem substrates and
allow longer flash-off |
| |
|
| Remedy |
|
Allow to dry until fully
cured, remove the wrinkled middle coat and
the affected area of the substrate and apply
the paint system again. |
|
Before applying the middle
coat, lightly sand the entire area. |
