| Definition |
 |
Small raised
dots appearing in the paint system. |
| |
|
| Cause |
|
Moisture was absorbed by
the substrate. |
|
Surface was not allowed
to dry properly after having been wet sanded
(particularly a problem with polyester products). |
|
Air humidity was too high
prior to painting. Temperature fluctuations
resulted in condensation. |
|
Pores / pin holes in the
substrate were not sanded out. |
|
Polyester products were
not isolated. |
| |
|
| Prevention |
|
Dry sand polyester products
and isolate. |
|
Carefully sand out pin
holes or apply more putty to fill them. |
|
Check the air humidity
regularly. |
| |
|
| Remedy |
|
Sand down the affected
area completely, sand the remaining surface
well until it is matt in appearance, clean
with silicone remover, apply surfacer and
then middle coat. |
