Kilz Paint Question

[chief ben]

I bought a new storage building that I'm going to use for a small work shop, i'm going to put my Lathe & a new smaller milling machine in and a work bench & some tool boxs and a place to sharpen all my drill bits with my Drill Doctor, I insulated it with R-11 insulation, and will put elect heater and a AC unit in it. my Question is I want to paint the OSB I put in it an off white.
A friend said you can use kilz paint and they can put color in it and it will only take one coat, it has some black writing on the OSB, will this work with only one coat?? Thanks.

not in my experience.

I have no idea, but my vote is no as well. Nice shop!

I don't remember the kiltz name I get but it is by kiltz. We used it on some of thee woodwork in our house and it covered up the impefections If I remember correctly great. But it needed a coat of paint after it dried. I tend to look at kiltz on wood as like primer on a car.It still needs a coat of paint in my experence. But around here its not to bad at lowes. Maybe 10 or 15 a gallon. I usually put a good coat of kiltz on wood then see if I need another coat or just spot touchups. I then put a coat or two of paint on it. I do that and I have had good luck with it. But just the kiltz by itself I have never done that. I think it may be sold as kiltz wood base coat or primer.

Most of the experience I've had with Kilz is as a sealer application. Can't say it would cover much with just a colorant added.

I've taken to using Zinnser123 as a sealer/primer. Much thicker and can cover in one coat. Could probably add a colorant but I haven't tried it.

Bullseye !!

I mixed and sold paint for many years. There several Kilz products on the market. Most are familiar with their oil based, fast dry primer and their various types of latex based primers. They also make a line of actual paints with bases designed to mix colors. In my experience, I have never seen Kilz or any other brand cover things such your black writing in one coat. Kilz primer is designed to seal the stains so your paint top coat will cover better and adhere better. You may still need more than one coat of paint top coat. As far as the primers go, I prefer Zinser Bin (oil based), or Zinser Bullseye (latex based), over Kilz.

Thanks Guy for the Advice, I guess I will have to spend just a little more money, and a little more time before I start moving things in.
Thanks Again.

I agree with the recommendation of the Zinser Bullseye (latex based) it works better than anything else I have ever tried.

I think you need to use a OIL base on OSB!!

 

[kfainf]

I think you need to use a OIL base on OSB!!

I agree on the oil base on the OSB. Unless the OSB is exterior sheathing with the coating on it, the water in the latex primer may cause the strands to lift and peel.

By the way, the Kilz fast dry is NOT oil based; at least it didn't use to be. It's alcohol based, more commonly known as shellac based. It covers stains by absorbing them. The stain does show in the primer but then when you top coat it with paint of choice, you can't see it anymore

In my experience, Kilz is a good product. I have, however, had more success using Sherriwn-Williams "Pro-Block" latex sealer/primer. I use an airless sprayer. I find an excellent base and sealing effect with the Pro-block. I am saying this as I have so far probably painted about 250 apartments with it. (I am in the property management business). The "Pro-Block" product is excellent for sealing against water and grease, etc. I like oil based Kilz, but the fumes send my sinuses into orbit!! What I would do on the building (I have one identical to yours) is to spray a good coat of unthinned Pro-Block, let it dry depending on your weather, and then spray my finish coat in a couple days. I think you would be very satisfied with the job. I was amazed at the photo of your building, I thought I was looking at my own!! Mine is even the exact same colors as yours.

Like everything, Kilz was a GREAT product 20 years ago. I just spent the last month painting two 2,000 sft buildings inside. Used half kilz and half Olympic fast hide eggshell white. I found no difference between the two, in fact, the Olympic may have covered better than the Kilz. I was trying to cover reds and oranges. Some light yellow I tried to cover even needed two coats of kilz, the reds and oranges took 4 coats rolled on.

Nothing covers the way they say it does.

I painted the inside of my garage (OSB) with 2 coats of Kilz. And the blue lettering still shown thru. But i still went on with a top coat of full gloss oil based white top coat. I put on 2 coats and the lettering STILL shows thru? Oh well its only a garage!

Good luck

I am with the rest that are saying kilz will not cover the letting with one coat. I have used the oil based paint in the past on wood to seal in dog urine, and the floor boards it was coated on had lettering. It took two coats to cover the lettering.

I painted mine with Zinser Bullseye brand primer then followed up with one coat of Olympic latex all from Lowes. No problems and am happy with the results.

Kilz will NOT cover the markings in one coat. It is designed as a primer, not a top coat. One thin coat that is allowed to cure will seal in stains/ink so that it won't bleed through the top coat. It says topcoat in 1 hr, but for best stain bleed protection it needs to cure for 24.

I just finished my shed about 2 months ago - very similar to yours 10'x12'x10'h gambrel. I sprayed one coat of Kilz and topcoated with a mis-tint of the cheapest paint at HD. 2 gallons of Kilz 2 latex and 2ish gallons of semigloss covered the OSB great. The framing is treated and that bled in a few small spots, but the OSB markings are gone.

BTW - 2 gal Kilz 2 at HD is $20 and the mis-tint 5 gal was $15, so I've got $35 in the walls and ceiling. I painted the floor with the Behr 1 part "epoxy" floor paint - 1 gal covered w/2 coats. Totally worth the effort - painting it made a world of difference.

So, it took 2 gallons to topcoat your primer? I am trying to figure out hom much it will take to do my 30x40x12.

Primer aren't designed to cover, but to seal. Stain blocking primer is designed to seal the stain so it doesn't keep bleeding through, not to "hide" the stain. Paint (top coat) is designed to cover.

I would do one thick coat of a stain blocking primer of your choice. In this case I would probably use an oil base to not 'raise the grain," more like raise the flakes with OSB as water and OSB really don't go well together. After that I'd put on as many top coats of paint as it took to make me happy.

OSB will **** up a huge amount of primer. Each successive top coat will use less and less as the substrate is further sealed.

Use a thick napped roller and a wide brush for the primer coat, or a sprayer.

This was with Kilz primer and then Behr paint.

The total job was one can of primer and I think one can of gray and white. I still needed two coats of color to get the results I wanted.
