Prepping Inside Window Sills
Hi,
I'm recaulking/repainting my inside window sills. I'm using a small electric sander to rough up the 18-year-old high gloss paint. This is a 5-inch diameter sander and I'm using 220 grit paper.
Sometimes the paper takes the paint right off leaving a noticeable edge between the old paint and the wood. Other times it leaves a nice, feathered edge between the old paint and the wood.
Not sure what to do - do I keep sanding until I get a feathered edge, or maybe change to 240 grit? How can I obtain a smooth feathered edge on the old paint?

I tested it with alcohol and found that the paint has an oil-base.
120 seems to "pick up" the edge of the paint more than 240.

If you're just trying to roughen the gloss, you don't really need an electric sander. Hand sanding with sharp paper or even course steel wool will do it.
