SW - Art DIR Adhesion Block Jpg

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.
