PEELING OR DELAMINATION
The process of the coating separating from the
substrate in either large or small sections or
a flaking off of the coating.

SOLUTION TO PROBLEM |
AVOIDING PROBLEM |
| INADEQUATE CLEANING - When improper cleaning occurs, the coating will not adhere to the oil, grease or contaminants present. |
The coating must be removed by stripping, shotblasting or other suitable means. Re-apply the coating after proper surface preparation. |
Properly clean the substrate and provide a suitable profile for adhesion. |
| NO PRIMER USED - If the proper primer is not used then peeling and delamination may occur. |
Remove any coating that is not adhering properly to the substrate. Prime and recoat. |
Use a suitable water-base or solvent based primer prior to coating the substrate. |
| INADEQUATE / IMPROPER ETCH - If an adequate or proper etch is not performed, failure can occur between the coating and substrate. |
Remove any coating that fails to adhere to the substrate and re-prep the area prior to applying the coating. |
Repeat etch until medium textured floor is achieved and properly rinse the floor. Allow the floor to dry thoroughly before coating. |
| EXCESSIVE MOISTURE - Excessive moisture can cause pressure which can lift coatings off the floor. |
Remove any coating that is not tightly bonded and test substrate prior to re-coating the floor. |
Use a moisture meter to test the floor or place and secure plastic on the floor for 24 hours to check for moisture. |
| SILICONE CONTAMINANTS - Some manufacturing processes such as welding or spraying can deposit silicones on the floor causing fish eyes. |
Remove any coating that does not adhere properly. Re-prep the area and re-apply coating using proper techniques. |
Lightly roughen coats between inter-coat applications and always observe procedures for recoat times. |
