We have a 1920s home with plaster walls. We took the wallpaper off,
scraped the wallpaper paste, and washed with TSP. It did not look like
the walls had ever been painted. We then compounded the cracks,
sanded, and washed with water. Then we applied Behr latex primer and
two coats of Behr latex paint. It looks great, but when we tape
between ceiling and wall, say, some of the paint comes off with the
tape. HELP! What can we do about this?

Thanks,
