A screen room outside my home has fixed plastic "screens" that are
waterproofed by a thin coating of clear vinyl or similar plastic
sheeting. Portions of the waterproofing layer are flaking off,
exposing the underlying screen grid. I would like to paint about 30
square feet of the screened area with an opaque paint to match the
house trim, as i have seen done to similar screen rooms in the
neighborhood. But none of my neighbors know how the paint job was
done on their homes. I would expect to sand lightly to remove flaking
plastic. What should I use for paint and how do I apply it to both
the intact plastic areas and the porous grid areas where the plastic
has flaked off?


Use some sort of vile chemical to dissolve the plastic. Then spray with your
favorite paint.

In the era before aluminum screen mesh and convenient spray cans, screens
were painted (and the steel wire HAD to be painted) with a brush! (This was
even before rollers.) Sometimes the voids filled with paint so you had to go
back over the screen with a toothpick to open them up.
