Yes, but the finish will be somewhere around satin. You can only do this if the paints are of the same type, i.e. either both latex, or both enamel (alkyd). Make sure you mix them together very well, and continue to agitate while you're painting.
Post edit: They may mix and go on alright, but interior and exterior paints are, however, formulated to have different properties. Exterior paint actually may not hold up as well indoors (Bob Vila). Most importantly, though, chemicals used in exterior paints outgas and are harmful for indoor use. Try some of the new low-VOC interior paints. They are much better for your health.
NO! paint will separate as it sits. Mixing will only keep it together for seconds. The walls painted will have flashes of flat and flashes of semi gloss. Its only OK to do as a base-coat when the paints are the same color, or its also OK when wanting to achieve that "I was drunk, when I did it" look.
As long as they are both latex paints, you can mix any sheen with any other sheen. Be cautioned though that you'll want to have plenty to finish the job and for touch-up afterwards because you could have trouble recreating it in the future.
It's not designed for the interior,but this is a lot better than using interior paint outside.Exterior paint will stay where you put it.It would usually be far more difficult to clean up any spills or mistakes though.
You can mix flat interior latex, and semi gloss interior latex. You will be left with a finish that is neither flat nor semi gloss. You would get a satin finish.
Yes, with the normal preparatory surface preparation.
Yes, depending on the mix ratio, you will end up with an eggshell or satin finish.
I tried many years ago they separate try a little let me know
Yes. You can paint semi-gloss latex paint over flat latex paint. It is not advised to paint over any latex with any oil-based paint. Nor is it advised to try and paint over semi-gloss paint with any other finish without first de-glossing the finish and priming.
Base paint is also known as flat paint, or flat wall paint, or matt paint and is a latex paint. Flat paint is just that, flat or dull with no sheen at all. Semi-gloss is an enamel that dries very hard and can be found in a low sheen (satin) a medium sheen (semi-gloss) and a high sheen (high gloss) Flat paint is usually used on walls and ceilings where as semi-gloss is used in kitchens, bathrooms, doors an jambs because it helps hold back the inherent moisture in those areas.
Many hotels that use paint use satin or semi-gloss latex paint in their interior applications.
No, you can dull satin or semi-gloss but not the reverse.
Yes, you can generally paint high gloss latex over flat latex paint. But you must do all the preparation work in the best tradition of any professional painter. All "flaking" must be removed and the raw wood primed. This will present a "smooth" surface for the new coating. Additionally, everything that is to be painted my be scrupulously clean and free of anything that will restrict the new latex from sticking to the old.
Yes, it will.
You can make it flatter, but not totally flat by adding a bit of talcum powder. Very common technique in modelmaking.

I've done it without any ill effects. It just dulls the semi-gloss a little.

Can I paint semi gloss over flat paint? Thanks!Barbara Phillips

I use semi-gloss latex.
