Paint for drywall & OSB

[matttys]

Here's a problem I want to solve when I move into my new (to me) house/garage in a few weeks.

I used Behr exterior paint to paint the drywall and OSB in my garage 5 years ago. When I'm removing heavy items (sometimes in cardboard boxes) from the OSB shelves and unbolting items (pneumatic reel, hose reel, etc) from the drywall the paint is sticking to the items that I'm removing causing blemishes on the wood shelves and tearing of the paint from the drywall.

Is there a specific type of paint that I can use that won't adhere to anything but the wall?

Thanks for the help!

Bare drywall needs primer before any type of paint. The drywall also needs to be free of any sanding dust. This has happened a few times in my garage because I had some left over drywall dust and I was in a hurry to get it primed.

sometimes exterior paint won't cure properly when it's used indoors.

oil based paints generally have a harder and more durable finish.

Drywall was primed with Kilz primer and mopped for dust.

I don't think you can really call the interior of a garage indoors as the garage door being open will vent the space effectively. Maybe oil based paints would be the way to go?

I painted my OSB about 6 years ago with a coat of cheap Menards oil based primer and a coat of latex exterior paint on top of the primer. None of it is coming off yet.

My recommendation is oil primer and latex top coat. That combination has always served me well.

For abrasion my walls are great and no paint is coming off; it isn't great where a piece of equipment or box has been in contact with the wall or shelf (under pressure). Maybe there isn't a true solution using conventional paints.

how long did the paint cure before putting those items on the shelves or bolting to the walls?

i've seen the same thing happen inside with window treatment brackets.

does exterior paint need sunlight, uv to cure properly?

anybody ever put a light film of spray silicone on the brackets before bolting to the walls?

I waited to load the shelves for a few weeks. Fixtures like the reels were installed after a month for the pneumatic reel and 3 years after painting the drywall for the water reel. It's odd that there isn't rhyme or reason, but the paint likes to stick to surfaces that are in contact under pressure. Makes me simply want to do unpainted OSB in my new garage to avoid issues in the future.

Couldn't agree more!!! Only problem in southern california is buying oil primer.... can't buy it at Lowes and HD sells only quarts!

Couple points: Oil base is getting harder and harder to find. My experiance with the Behr product has been FANTASTIC.

With the amount of time between application of the paint and installation of your mounts the only thing that comes to mind is the amount of humidity in the air. Your cure time sound fine.

My walls sweat when I open the garage door during an unseasonably warm winter day:

I.E. its been 10 degrees all week (non heated garage) then you get a 50 degree day and open everything up and the drastic change gets everything moist. your done for the day and close up shop so that water has to go somewhere..some evaporates and gets stuck between your walls and what ever is mounted there.

You may want to focus more on the paints finish: Flat, gloss, semi gloss more then the product it self.

Good luck.

This problem is called "blocking" in the paint world. You need a non-blocking paint. Latex will always block no matter how well-cured or how old it is.

From what I understand, non-blocking latex paint is pretty rare. To get non-blocking, you pretty much need an alkyd or oil based top coat.

I have had good luck with the cheapest Porch Paint that lowes sells for painting OSB. It did a great job in one coat but I did two since I had paint left.

As mentioned, you are having issues with the latex/acrylic paint sticking to items.

Generally, acrylic paint is 'softer' and 'stickier' than an oil-based enamel.

Solution: Use a paint that cures to a 'harder' and non-sticky film.

Moorestyle from Benjamin Moore with a good acrylic primer.

The oil based stuff was better but they've quit selling it here.

Great advice guys. I'm going to look into an oil-based enamel or a non-blocking paint.
