Rustoleum paint, can it be painted on bare metal??

[cnyeco1]

I've got a big grinder stand I want to sand and paint. I'm going to leave it outside so I was think of using a roller and rustolem grey to keep it from rusting.

Can I just roller it on or does it need to be primed?

I've always used primer. IMO it's 30 min well spent.

Read the application instructions, you can't get the paint without the instructions, they're on every can, and it will certainly take less time than waiting for one of us to get back to you with a typical, shoot from the hip, uninformed answer.

I always primer too. Makes me feel better.

I use primer, but some of the rustoleum paint cans say no primer needed and it can be sprayed directly on rust. Gotta read the label.

I would never think to not prime something like that even if it was going to be indoors.

Prime + paint. Put a coat of primer on it and 30 minutes later top coat it with two coats of gray. The paint will hold up OK w/o primer, but it helps with adhesion and durability of the coating.

I find the answers here to be pretty darn good. Some are better than others but taken together I find I get great advice (and try to dispense it too).

I'm just curious if you don't value the quality of information here why do you participate?

Self etching primer for bare metal will give it a bit more bite and take the paint. It has always worked for me.

Didn't mean to dismiss all of the information provided, but in this instance it seems pretty basic...the OP needs to paint something, he specifies a brand...why would you not follow the manufacturers instructions on how to get the desired performance from the product. Now as far valuing the "quality" of information here...lets go back to a previously posted reply in this thread...

A technically sound reason if I ever saw one.

Any other questions?

I never prime the brackets and such on the race car, but then Krylon 1613 is hceap, abundant and I can touch them up in a second as they come on and off the car. For stuff I really care about -LOL- I have a can of self etching epoxy primer. Not box store primer, this is from a real auto paint store. Works very well and the top coat lasts. For your deal outside, I would recommend that. It's also light gray, so it'd match your top coat.

I have painted many items without primer. I have painted many items with tractor/implement paint without primer with no ill effects. Sometimes just bare metal. It all depends on the preparation. Bare metal with no primer does not mean rust it just depends on the preparation and the specific paint. I have used tractor supply paint on three workbenches, grinder pedestal and two vises that sit in a garage with zero effects. I have painted to 2 garden carts that sit out year round with zero rust in three years with no primer just paint. I find that tractor/implement is very durable.

I don't mean to get into a ******* match but I would think that the OP could probably pick out the better responses from the not-so-good replies. Besides, I don't think that suggesting a primer always be used is such bad advice. It's certain better than saying you never need the stuff. But I definitely agree with you that the directions can provide, well, a lot of good direction.

I'm done, I'll leave it at that. Just in a difficult mood tonight I guess and you probably don't deserve it.

 

[cnyeco1]

I guess I should have been more specific with my question. I know that there are instructions on paint, but what I was wanting to know is if anyone had painted Rustoleum on bare metal without having to primer. I have painted stuff for years without primer, but never have used Rustoleum roller paint.

Thanks Guys, Cam.

WOW!! I can hardly believe that the suggestion by Tianci was slammed.
Oh, yeah, that's right, I forgot. I always get product information from either the internet, pizza delivery guy or a bus driver. Who would ever read the manufactuer's words? That would be a stupid waste of time!!
DUH!!

Yes. It's not as durable as when you prime it, but so long as the metal is clean, it 'works.' I live in a very dry climate, but still there are some things I've made that I know will slowly dissolve and I leave unpainted. Some things get a single coat of paint only. The ones I want to last get primered and painted -- and then repainted every couple of years.

Sometimes my time is more valuable than the longevity of the thing I'm making.

This is right from the Rustoleum website:


SURFACE PREPARATION Remove all dirt, grease, oil, salt and chemical contaminants by washing the surface with commercial detergent or other suitable cleaner. Rinse thoroughly with fresh water and allow to fully dry.

Scrape and wire brush rust or deteriorated coatings. Apply one coat of primer.

APPLICATION Stir thoroughly. Thinning not needed for brush or roller. If sprayed, thin up to 15% with acetone. Apply with good quality brush, roller or spray gun.

May recoat when fully dry, usually in 24 hours.

CLEAN-UP Clean brush, roller, and other tools with mineral spirits.

Yes, I probably was a little hard on him but I really wasn't reacting to his advice but to the following comment about the answers given on this forum.... "typical, shoot from the hip, uninformed answer."

I think that's a bit harsh and, as I explained, not representative of the feedback most receive here especially when taken as a whole.

 

[tcianci]

Oh, go ahead, slam away! Sometimes I run off at the mouth too It's all good fellas!

O.K. Guys, lets close this thread out. My mistake for asking a quick, simple question.

 

[Keep]

Holy ****, I would think by some of the answers on the forums the last couple days that the lot of you are PMS'ing!!

As to the OP. I used Rustoleum tremclad paint on my outdoor steel railings 7 years ago, no primer just scrape off the old stuff, paint on the new. It is just now starting to show a couple areas that could be re-touched.

They have seen some very cold winters, very hot summers, and they still look good.

As for the read the instruction folks, it says "Primer not needed in most cases"

I am not sure if you have the tremclad line of paint, if not you may want to look it up.

 

[cheap bastard]

Yes, even the no primer needed paints can do better with the correct primer and preparation. My personal experience with no primer paints has been they work well with just some common sense prep. Scrape rust and loose or all paint off. Using any sand paper 80 grit or finer, sand the whole surface. Wash off with thinner, acetone, spirits or denatured alcohol. Use rust converter on any remaining rust or any pitted areas. Paint away.
If the item to be painted is flexible such as sheet metal, primer adheres to the metal better than paint. Those items therefore get primed first. This post represents my experience only and should used on experimental basis only.

Ah, don't worry about it. It was an honest mistake.
