I have an old wood window sill that I want to install PVC Trim over
After I scrape out, fill any rotted areas with a spackle or epoxy mix and sand what other prep do I need to do before attaching my pvc trim, caulking & repainting?
Because of the design of the frame there are infact 2 small sills where the storm windows used to be. When the windows were installed PVC trim was put around all sides of the storm window area with a quarter round base (to cover the sloped sill gap). The paint on the large sill has taken a beating, so I want to extend pvc trim over it.
I would prefer to keep self adhesive flashing tape options off the table as its difficult to find & costly. At the very least I would think priming any bare wood before installation would be the best cost effective option.
