Yet another painting PT thread...

I recently completed repairing some rotten wood arould my garage, now its time to repaint.. I read a few old thread and most say to use a oil based primer..
Is the absolutely necessary??
I have some Kilz exterior water based primer sealer and also some behr premium plus primer sealer, can those be used...

It depends...

...on exactly what you are priming and why

Oil is the best for spot priming trim scraped down to bare wood, and bare wood that has knots or other issues
You can certainly say that oil-based is usually the way to go for this project

Could you use latex?
Well, if it's only new clear (no knot) non-bleeding (not cedar) replacement trim wood, you could use a latex primer

W/o further further specific information that may open up other options, I'd say the oil-based is best for this type of project

Pt?

..wait, do you mean Pressure Treated Pine?
For that, for sure an oil-based primer would be best
I wouldn't even consider using a latex primer on Pressure Treated Pine

the trim around the garage is pressure treated 1x4 and 1x6's I'm not sure what kind, what ever the stuff is the sell at home depot..

now there is a 1x10 cedar plank needs to be painted as well...
so oil based is the way to go..

Yup

Yup, it's oil-based for you for sure

I's recommend getting some Ben Moore Fresh Start or Sherwin Williams Prep Rite
Oil (alkyd) based
(ask the salespeople which one is the right one if your not sure if you have the right one though, FS comes in oil and latex, and PR comes in many flavors for different projects)
Much better than any primer you'll find at HD, if your local HD even still has any oil (most don't)
You might only need a quart

Well...you asked....

I've used both in other applications
To be straight, I wouldn't recommend either for any application
Both have a high failure rate
That doesn't mean they wouldn't work OK for something else
I'm just not sure what, I couldn't use them on a job, as the threat of failure is to high (even a 20% failure rate means 80% worked OK, but that's too high a failure rate for me to use on a customer's house), and I wouldn't use them on my own home for the same reasons (I don't want to spend my days off fixing work I already did on my home...lol)

I might use them on garage shelving or the shed or garden fence or something
Or even let them dry out and dispose of them if there wasn't too much left

I'd recomend using SWP's A-100 exterior oil base primer.

Sorry about that marksr (he's the Sherwin Williams expert)
Yes, not the Prep Rite, the A-100
But I should know, if I don't have a can of Fresh Start oil open, I've got an open can of A-100..in fact, I used A-100 only the other day....
(the can isn't even the same color as the prep Rite-what was I thinking?)

It is better to caulk after priming but what's done is done. The worst that will happen is the caulk will fail prematurely.

I can't catch a break

OK the nearest SW is 75 miles away but there is a porter paint much closer..
do they have a comparable primer or should I trek to SW..

If I was at the job, I'd ask Porter if they have a good oil primer
I don't recall using Porter before, but I wouldn't go 75 miles for a primer
It's my understanding from other contractors that Porter products are just fine

I've used Porter paint occasionally and don't recall any issues with the paint quality - always go for the top line products and stay away from anyone's cheapest.

It has probably been over 15 yrs since I've used porter and the only negative thing I remember is the amount of marterial in their containers - 5gal bucket only has 4.75 gals and a gallon can has less than a gallon don't know if it is still that way or not.
