Interior primer under exterior paint?

Hi guys,

I have a bunch of pine planks to pint. They're not not PT, just clean white pine wood. They will be outside. I plan to prime with Kilz and topcoat with SW Superpaint.

What is the danger of using interior primer and covering with exterior paint? The Kilz exterior is like paste but the interior can be had in rattlecans. That sure would be easier. Can I get away with it?

Thanks!
Tom

If you're taking the time to do the project, why not spent $20 and get the proper primer? You can get a gallon of Cover Stain for less than that.

Its not the money, the amount of spray cans needed would cost more than the gallon of primer. Its just that it would be so much easier with the spray. I'm beyond sick of painting lately.

If it won't do a good job I won't do it, just thought I'd ask.

buy a paint sprayer. it'd be a good purchase as you'll surely use it again.

The original Kilz works on bare wood

You should be able to "get away with it" lol
I can't remember doing it myself, but I can't see why it won't work

It won't really be cost effective if you have a lot to do though
It's expensive in the rattle cans

*I do have to point out, as I'm sure you know, an exterior primer would be the proper way

I figure the primer makes the paint stick but the true protection is in the topcoat.

I don't know if I'll do it this way or not. I feel like I've been painting for months, everything I do has to be painted first, ya know? I'm tired and I'm whining about it

Thanks much for the replies! I do know that using the exterior primer would be the proper way

wait a minute......you've got flat boards to paint? how is using spray paint easier than a brush or a roller? i've used spray paint before & i don't think it's easy at all. the fumes are horrid, the overspray is annoying, and getting even coverage is very difficult. a small roller would be the way to go.

<shrug> I find it easier and faster to use the can than the thick primer.

Kilz exterior primer is thick. After a while its like spreading paste.

you could still do the edges with a roller. roll the edge first then smooth out whatever globs onto the front or back. on TV i see them using those little wiener rollers all the time.

I don't have a wiener roller No big deal, most likely I'll roll and brush on the proper primer. Slick got me feeling bad about being lazy!

Wha'd I do?
I had to say the "proper way" thing
I can't have all our DoItYourself.com Community Forums > Interior Home Decorating > Painting > Thread readers think it's perfectly normal to use interior stuff outside
Then they'll all start using Kitchen & Bath paint on their decks
Complete Anarchy!

They're great for priming planks

Paint thinner is sold for when the material won't apply correctly for the given job. That said I would only use rattle can sparingly -THEY DON'T PUT OUT ENOUGH MATERIAL.

If you are going to paint for a living, you really need to invest in a wiener/cigar roller or even one of those 'wiz' rollers. Once you use one a couple of times you will kick yourself for not buying one earlier.

I would also second slicks' comment that while you can occasionally get away with using the wrong material [interior primer-this case] it is always better to use the correct material for the job.

Ack! Paint for a living? Save me from this terrible fate! I'm just trying to put a broken porch back together!

Thanks for all your help folks. I'd have a terrible time getting things right without you.

I'll be using the correct material for the job I don't even know what a wiener roller is!

Sorry, my fault I've been on vacation [maybe my brain still is ] and I confused you with wannabe who is just starting out as a pro painter.

Well, the promised beautiful day didn't show up, it was cloudy and looked like it might rain all day so I didn't paint.

I did the cuts done and got my supplies; a fresh can of Kilz exterior and some wiener rollers Maybe I'll get the painting tomorrow.

Thanks again!

Paid? I wish! This is all my stuff,

A little yellow paint is all he needs for those weiner rollers.
I relish the thought.

First side and edges primed. Will flip and complete in an hour or so. You guys were right, as usual, those little rollers are great for this.

Won't get the topcoat done today, just not enough hours
