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
|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.
