who knows about where to use latex house paint?

[keakar]

yes I know, USE IT ON YOUR HOUSE. yuk yuk yuk now to be serious:

I have some extra (4 gallons) walmart brand "Color Place Exterior Flat latex Paint, White" and I was going to use it for the interior of the house. its left over from a 5 gallon bucket so I cant return it and I figured I would use it for the ceilings and trim inside the house.

somebody told me not to use it inside because exterior latex paint is different and I should go buy some interior paint for inside. I know in the past exterior was oil based so there was good reason you didn't want to use it inside but since everything is latex paint now, so my question is, is there really a reason any more not to use the exterior latex paint inside and if so why?

If I was buying new paint I would buy it for its intended use and I realize exterior latex is still made a little different to stand up to being outside but does that make it not suitable for interior use?

any painters or paint contractors out there can clue me in as to the do's and don'ts of latex paints?

Use it on walls only if you want a flat finish, which no one does these days. My opinion, store it to do touch ups outside. Buy new paint for interior.

so there is no reason not to use exterior latex on the inside except for the finish being flat then?

I actually don't mind flat paint inside for bathrooms because the walls don't collect water and drip when it gets steamed up in there.

I hadn't thought about the finish question so im glad you mentioned it, i'll have to buy some semi gloss for doing the ceilings and doors and i'll have to give it more thought if I want every room to have flat finish walls but to me color is more important then finish so I think I would be happy with any paint finish especially if it saves me $100 on new paint.

I have mixed flat with gloss 50/50 before to make semi-gloss paint but I don't suppose there is any simple "sheen" additive to put in it to turn flat paint into semi-gloss is there?

Just remember a flat finish WILL show every single finger print hand print or smuge of anything that touches it! this is the reason most don't use flat inside a home and if they don't want the finish to be shiny like semi gloss or satin they usually just go with an EGGSHELL finish because while this one isn't shiny it doesn't show the places where the wall has been touched like a flat finish will

Eggshell and satin are pretty much the same finish. Some manufacturers call it "satin"...some "eggshell". Both are pretty durable and, like you said...won't make the smudges part of the décor.

Satin had a slight more shiny finish then eggshell it's right in between flat and satin go to your local pant retailer they can show you the differences all next to each other on an example pallet only way you can actually tell the difference between them is when they are next to each other

Use it as a primer inside.

I thought raw sheetrock HAD to have a primer coat to seal it first or the regular paint would just peel right off of the compounded areas?

I don't know anything about paint or painting

[latravcha]

I dont know about that but I have used extra paint as a primer before and had no issues. Dont know what color it is but if it is a darker color you dont want to prime with it.

The flat latex you have can be used as a primer on raw sheetrock because the vinyl primer that is formulated for priming is basically a lower-end acrylic flat designed to keep the sheetrock from absorbing the finish. Very little "priming" involved.

As far as using your paint inside....it's perfectly fine. Folks don't use flat/matte finish anymore, tho. Even on ceilings they use satin...mostly because it brings out the texture on a skip troweled ceiling. On walls and trim, the satin is able to be wiped...flat, not so much. You'll actually wipe the paint off the surface tryin' to clean it. The reason the moisture shows on satin/semi-gloss walls in bathrooms is because the paint is blocking it from soaking into the sheetrock. Flat paint in a bathroom is NOT a good idea. It's prolly more porous than the sheetrock, itself. It will eventually begin to peel.

Good luck and holler at me if you have any questions and, remember...paint is only as good as the surface you put it on.

thanks, that's great news, at least using it as primer will not go to waste.

the bathroom I painted was over around 6 or 7 coats of other paints so I think I avoided the moisture passing through it issue. because of its dull finish it doesnt show surface moisture or let it drip or run (nobody ever turn on the damn vent in there but me ) so that's why I thought it was great. glad to learn flat paint is not a sealer so I should NOT do that for bathrooms and other wet areas like kitchens and laundry rooms.

can you tell me the best applications for gloss vs semi gloss?

im trying to understand how to choose the best overall finish to use all throughout the house for durability, cleanup, and long lasting?

also, did I make a mistake using flat for the exterior of the house? its all exterior treated T1-11 plywood so should I go over all of it with spraying on a clear sealer and if so what would you suggest?

The acrylic will do ok on the T1-11. After a few years of normal wear it will begin to take on that "stain" look...which a lot of people like. No need for any sealer cause I don't think you'd want any sheen.

Semi-gloss vs gloss..........

Gloss finishes kinda come and go as far as popularity. Contrary to what you might have heard...it is no more durable than semi or even satin. In fact, as far as staying put on a properly prepared surface...the flat acrylic will outlast them all. It's just not stain resistant. Satin is a subtle sheen that will suffice in any home. The secret is to put an adequate amount of paint...usually 2 even coats. It's tough as nails and doesn't tend to show every flaw in the sheetrock or trim.
