Preparation

• 1). Wash the window with soapy water, using a coarse sponge. Rinse the PVC plastic, using a hose. Don't just rinse the window, or adhesion difficulties could follow.
  
  
• 2). Promote adhesion by abrading your window using a palm sander, stocked with 220-grit sandpaper. Stop once the PVC feels rough. Don't leave any slick areas, as these will reject primer.
  
  
• 3). Place tape along the surface next to the window. Leave the glass exposed. Position a drop cloth beneath the polyvinyl chloride.
  
  

Finishing

• 1). Brush latex primer onto the polyvinyl chloride. Synthetic paintbrushes are appropriate for this task, however, not all are the same. While nylon brushes leave marks in the finish, polyester ones promote smooth results. Let the PVC dry for two hours.
  
  
• 2). Use the hose to rinse primer from the brush.
  
  
• 3). Paint your polyvinyl chloride window as you primed it. Let the PVC dry for two hours.
  
  
• 4). Remove unwanted dried paint from the glass, using a razor blade.
