Paperhanger asks dumb painting question

I figure you don't use interior paint on the exterior because it wouldn't hold up...

but are there any reasons not to use exterior paint on the interior?

I'm asking for a friend.

Depends on the situation. The chemicals used in exterior paint are stronger, so I suppose there could be issues with someone potentially getting sick from the vapors. And the smell will last a little longer. I painted my current bed frame with some exterior paint and it smelled for about a month. But, it didn't make me sick; at least that I could tell.

But, is it really going to save that much money?

when I worked a small Mom & Pop back circa 1990, a woman came in asking about the advisability of using ext for int. I told her the same that I said above. She mused a bit on the words, and then, sorta with a thinking out loud voice, said something about that being the cause of her facial ticks - which she had.

Underdog, a few of us have basically said the same thing. What would be the advantage of taking a chance ? Just tell him, "I wouldn't"

It's settled in my mind. It may be unpleasant to say something but I will.
Some people get things locked in their minds.

Exterior paint is typically not formulated to lay down quite as nicely as interior paint either. It is more about durability than appearance. That and the problem with a stronger odor from the mildewcides in exterior paints are going to be your main issues when using exterior on an interior job.

If you have some white exterior enamel and need to paint a few interior trims, I would use it and save the money.

I bought a gallon of exterior white enamel a few weeks ago. I had some exterior trim and bathroom trim to paint. I used it on both interior and exterior. It didn't smell strong and looked fine on the int bath.

There are some paints that are for both int & ext.

If I was doing a whole complete room, sure, I would buy interior paint.
But if I had a gallon of white ext., enamel left over, I would use it on int., trim and save the money.

at the risk of peoples health?

I think not
who's $ are you saving:eek:

the paints certainly are different, but just look at the ingredients of that exterior can, it was not made to come inside, period and end of discussion...........:notworthy:

What are you gaining by using an ext paint inside? Aside from the previously mentioned bio-cides and off gassing? Say you have 5 kids banging toys, peeing on the walls and throwing spaghetti sauce everywhere. Their are int paints that can handle it. I've put floor paint on interior walls because of excess kicking and scuffing but it's an int/ext product. Or use something like Super Scrub Ceramic which has microban, an antimicrobial agent in it. I just never saw the point to it. :no:

This discussion gets muddled when you consider that there are plenty of paints made these days by all manufacturers that are labeled interior/exterior. I am a huge believer in reading the words written on the can and following them. I do this because I know that if I don't do what the label says and bad stuff happens, then it may be my fault because I didn't follow the directions written clearly by the manufacturer. That said, you may be able to use outside paint on the interior, but if the manufacturer had really intended for that product to be used inside, it would say for interior use on the label.
