Crinkling

Cause

Softening of a previously applied coating caused by applying a subsequent coat before the underlying paint film is totally dry. Problems of this nature can also be as a result of applying paints such as chlorinated rubber which contain strong solvents over alkyd based paint finishes.

This type of problem can also occur when water based coatings are applied over an oil based sealer such as Alkali Resisting Primer or Stabilising Solutions for use onto a powdery substrate. And where the sealer coat has remained glossy and not flatted down before applying the top water based coats..

Solution

Occasionally it may be possible to remove the ridges. In severe cases complete removal may be necessary before re – painting can take place.
