Exterior paint used in interior

Posted by jj3000 on February 10, 2005, 8:20 pm

When I went through the paint left by the previous owner, I found a
couple cans of "weatherbeater" exterior flat paint that matched one of
the bedroom walls. I am pretty sure that was what they used to paint
the room.

While it's nice to have a weatherproof effect and one coat coverage
etc, is there any issues using exterior paint inside the house? The
only thing I would be concerned is the mildewcide that is used in some
of the exterior paints. Does that stuff spread around in the air or

it just means it's not a good idea to eat your food off the walls? <g>

Would it be sufficient to cover it with a interior paint if I choose
to repaint the room?

I've read that exterior paint should be used in a well ventilated area -
like the exterior of your house.

Years ago that made a lot of sense with the oil and lead based paints.
Today they are different. Exterior paint often has UV inhibitors and
additives to keep it more flexible, but can still be used indoors.

It's *still* a good idea. Those "additives" are chemicals.

Is there a phone number to call with questions on the paint can? I'd try
calling it. If there isn't you might want to try calling Behr as if it were
their paint. I called them once and they had smart people answering the
phone.
