Eliminate brush marks by sanding and repainting or by skim coating with drywall compound and repainting. Both techniques are easy.

Sand the brush marks with
If you have unsightly brush marks left over from a bad paint job on walls, take heart. You have two ways to eliminate them.
Try sanding first to see if that
will work. Use 80-grit sandpaper
on either a sanding pole or a
sanding block (Photo 1). Use a “clog
resistant” type, such as 3M Sandblaster
sandpaper, or wipe the sandpaper often
with a stiff brush to keep it from clogging
up. Avoid the temptation to use an electric
sander to make the job go faster. It'll heat
up the paint and cause it to get gooey
rather than sand away the brushstrokes.
Skim-coat the walls with topping
compound to cover the brush
If sanding doesn't work or the entire
wall has brush marks, save yourself time
and effort by applying a thin coat of topping
joint compound over the walls using a
12-in. drywall taping knife—a process
called skim coating (Photo 2). Then
smooth out with 100-grit sandpaper any
rough spots in the skim coat, apply a coat
of primer and paint the walls. Skim coating
ensures that you'll end up with a (nearly)
perfectly smooth wall.
Have the necessary tools for this DIY project lined up before you start—you’ll save time and frustration.
Avoid last-minute shopping trips by having all your materials ready ahead of time. Here's a list.
