A.13 There are several things that can cause delamination. First if you did not clean the surface properly. Seal coatings will not adhere to dirty or oily surfaces. Any kind of wax or tire cleaners used in drive, and flushed off with a hose can cause the material to come up in patches. Oil stains have the same effect. Seal coating installed when the temperature was cold, and not getting to cure properly can cause massive failure. Water based seal coating put over an oil based sealer can have the same effect. The pitch or sap from trees can cause this same type problem.
