DESCRIPTION

Undesirable adhesion between two painted surfaces or between paint and weather stripping. The paint sticks to itself or to the weather stripping when a window or door is opened and usually leaves bare patches of substrate.

POSSIBLE CAUSE

• Not allowing sufficient time for the coating to dry before closing doors or windows.
         

• Use of a paint with low block resistance (e.g. when two painted surfaces touch, the paint tends to adhere to itself).

SOLUTION

See Lead Information.
          

• Paint with an oil-base coating or use a high quality semi-gloss or gloss latex with good block resistance.
   

• Remove all loose paint by scraping or other methods, and sand the surface to smooth out any rough edges. Remove all surface contamination by washing with ProClean Professional^® Prep Wash Concentrated Cleaner or other appropriate cleaner; rinse thoroughly and allow to dry. Glossy surfaces should be sanded dull.
   

• Prime as needed and topcoat. Follow paint label instructions regarding dry times.
   

• Application of talcum powder, wax, or soap may temporarily relieve blocking.
