Either Fresh Start from Benjamin Moore, or Sherwin William's slow drying exterior oil based primer. Slower drying results in longer lasting finish as it has a chance to really seal the wood.

 

Is it chipping to bare wood or between coats? What type of wood is it and what is your prep going to be?

 

Mad Dog, then CS.

Peeling and potential bleed through fixed.

 

Chipping=peeling?

Pictures help

California's Troubleshooter long oil is great.:thumbup: I have 10+ year old jobs on ocean front homes still looking good with that primer.

 

Chipping, peeling, whatever. Scrape it sand it mad dog it cover stain it and sleep well at night. Basics really this should be a non issue.

Isn't Cover Stain oil based? I could be wrong, but I believe the manufacturer states that only acrylics can be applied over Mad Dog Primer. Recently they began putting an additional sticker on the lid stating that only acrylic satin or semigloss can be applied over Mad Dog. No flat paint! I was halfway through a job, and ended up having to go back and paint over the primer with satin prior to applying the flat finish the homeowner had selected. A real PITA.

 

I've used both the BM fresh start penetrating oil and the SW exterior oil with good success. I would recommend reducing the SW primer 10% to make it easier to work with. It's pretty thick right out of the can.

 

I go with a slow drying oil primer, most paint stores have them so ask your normal store.

 

Nobody suggested kills2 yet?!?

OP asked for oil exterior so no kilz2

 

I used Muralo exterior linseed oil reinforced oil primer already. It seemed good. Got it at the local hardware store. Anymore all oil primers seem the same to me. I like the fact the Muralo was linseed oil reinforced. It was like 45$ or more a gallon though.

 

I've used tons of that primer, X-200 I believe it's called? It's not a long dry primer. But to be honest I haven't seen a difference between long dry and quicker dry oil primers.

 

I like BM fresh start 100 penetrating oil.

 

Thanks everyone. 3 votes for BM freshstart. it it's under $20 per gallon well give it a try.

Nothing beats a long oil for exterior wood. "my opinion" Here in California I know of two products and they only come in quarts - BM's 100 and behr has a slow oil too that is not bad. BM's quart is close to 20 bucks and Behr is around 12 bucks.

Also want to add for that old dried out wood, a coat or two of boiled linseed oil will bring a little life back.

slow drying will always be better than fast drying??
What do you guys think about Zinsser? its $18 per gallon and feels hardcore.

Our prep: house already power washed/removed a ton of loose paint. We r going to run the Milwaukee fiber disk sanders over the entire siding and prime.

 

I never understood the point of pwashing before sanding myself. You end up with a ton of dust on there. Pwashing never replaced scraping and sanding for me. It never took off more than 30% off wood and if you do it's probably damaging the wood.

Yes there is a difference in primers but if you're looking to save 150 bucks coverstain works ok.
How long have you been painting?

u r saying you dont power wash at all or wash after sanding? Been painting for awhile, not a supreme expert like you im sure

 

I would add a sizable percentage of penetrol to your oil based primer for some additional ahesion to the old surface.

 

I used to like to power wash...take a day off to fish, and then sand.

Then I'd take my leaf blower and blow the dust all over the city.

That was before RRP.

(Those where the days my friend)

 

I do find it funny that your thread title was "best oil based ext primer", when after all the suggestions you then mention you actually want something under 20 bucks.

For that price range, then yes, coverstain would be the best fit. It's good but in my experience, it doesn't perform as well as long oil.

 

Coverstain rulz

I used it today...and I have specs all over my forearms to prove it.

(takes about 3 showers to wear off)

That's quality!

 

Coverstain days are the best because I get to rub myself all over with baby oil.

Baby oil is actually a great way to get it off...
And you can always get help with the process.

 

Definite contradiction when you say you want to go the extra mile and use good primer, but also want to pay less than $20/gal for it. You want to spring for something, go for the Fresh Start.

 

If you're trying to stay under $20/gal why not just slather it with whatever junk latex HD is selling and call it a day? If you're interested in quality products then I would stick with the BM, SW, or California products that have been mentioned.

 

Here now get a grip!:notworthy:

 

Thank you all for your help. Have a great weekend

 

got a house with paint chipping EVERYWHERE! we don't do allot of jobs where we need prime an entire side, but here we have to prime two huge walls. Right now we use zinsser oil exterior and love it but this house is in such bad shape I really want to give them a super quality prep job. What you guys use? Need something that can be sprayed and back-rolled

I actually like to mix fresh start oil with coverstain it seems to have a nicer flow with a nice body. sometimes ill add a little japan drier so its not tacky 24hrs later
