Customer Reviews for Rust-Oleum Specialty 30 oz. Dark Gray Magnetic Primer

Rating provided by a verified purchaser

Good instructions about extreme stiring needed and cleanup. Works very well! Thick paint and should be applied on a very smooth surface or thinned to ensure final smooth coat.

It didn’t turn the wall magnetic

I followed the instructions completely, put on 3 coats, and there wasn't even a hint that a magnet would stick to it. I might as well have tried to stick a magnet to a piece of wood. Complete waste of time and money.

The directions recommend using a paint roller—don’t. The metallic/magnetic element soaks into to roller-sponge and as you dip more attracts into the roller. Soon the magnetic strength in the roller becomes so strong that it pulls the primer up off the surface—making it bumpy not smooth. Now i have to choose between having a bumpy chalk-board, or starting all over with new materials.

Make sure to mix very well before opening it. Once opened, make sure to constantly mix it while its being used. The minerals will settle to the bottom if you leave it. Its magnetic as well so mixing will be harder than other paints. I highly recommend using the paint shaker they offer at the stores. Use a dense FOAM roller to apply. Use disposable gloves. Use splash proof goggles. Use a respirator mask. Protect nearby areas with disposable covers (newspapers, tape etc). Apply in well ventilated area. If you want to clean, it recommends a xylene paint cleaner (I do not recommend using xylene) If you really want to clean using xylene, please make sure to research it before buying. Instead of trying to clean with xylene, I recommend using every last drop of the primer. Then letting the primer completely dry out wherever it is (roller/ can/ tray/ newspapers), and throw it away. If you have a lot of primer left in the can, take it to your local recycling center.

I oreder this on Oct. 19 and I stil have not recieved it. It is now November 10th. and I can not get anyone to help me. :(

The paint was old and could not be stirred. Returned the paint

Coverage is really bad on a foam roller. Project took a long time and it dried into a chalky consistency that was a mess to paint over. The cherry on top is that it’s too weak to hold up a small magnet. Don’t waste your time.

Magnetic didn’t work well, couldn’t even hold up 1 piece of paper after two coat of paint.

This thing is thick, the instructions says mix well and we did but didn’t say keep mixing while you applied it. It ended up being a rough surface instead of a nice one. Anyway the magnetic property works fine.

Have to have Special magnets, wasted 22.00 and the time on project for magnets not to stick. Now have to start project all over and go different route which is the way I should went the first time. Useless product. And is very difficult to work with and super messy. Don’t waste your money.

I’m some spots it wasn’t very effective. Not sure why. But for the most part it works really well even after you put a top coat on it.

Made some great craft projects with my daughter. We bought frames with large boarders, painted the Rust-Oleum Specialty 30 oz. Dark Gray Magnetic Primer on. Using a roller we rolled out 3 thick coats, letting it dry real well in between each coat. It was stirred real well before each coat, it does take time to stir it, scrapping the insides of the can getting it mixed real well. At first it seemed gritty, but it dries pretty smooth. We did paint a color over the magnetic primer also. We made some cute magnets and they did stick pretty well. And it held a piece of paper onto it.

Super thick. Strength of grip so so. Now rethinking our plan. Was worth trying but failed for our intended use.

Was so congealed it was impossible to mix. Taking it back tomorrow.

Hard, poor coverage. Poor product

If you're expecting magnets to stick to it like a piece of metal then you'll be disappointed. That being said, things like kids alphabet magnets will hold to it with no problem. As some have stated in their reviews, you might get a can that has separated and has thick "chunks". Getting those chunks to dissolve back into solution is the key and it takes lots of stirring...like maybe 10-15 minutes. I used a regular paint stick stirrer but a screw driver followed by the paint stick might work best. Roll it on with a foam roller. Take your time, this stuff isn't as easy to work with as paint or regular primer. FWIW I applied 4 coats and was pleasantly surprised with the outcome, especially since I read the reviews ahead of time and still decided to try it.

Pin would not stay on painted surface

I bought to use in my classroom. It was so thick it was hard to stir and make smooth. Once that was done I followed the directions completely, 4 coats. It dried well, was somewhat magnetic, but once the chalkboard paint was applied it lost all magnetic qualities.

Looks great in my kitchen pantry wall. I am using this and then covering it with Chalkboard paint so I have a magnetic and chalkboard surface in my kitchen for recipes... FYI - I did have to put on two coats before a magnet would stick...

I did everything the instructions said. I had to dump the paint out in a large bucket and mix it with a drill mixer because the metal was so stuck that after 20 mins trying to mix the paint in the paint can I gave up and switched to the bucket. Still, after painting a few feet I noticed that all the metal shavings were sticking to my foam roller rather than the wall. I switched to a regular roller and after a few swipes the same thing happened. After letting it dry I tried a few different magnets and only the strongest stuck...and that one failed once I tried to put 1 piece of paper under it. Don’t waste your money.

It is the thickness of tar and creates a super rough texture on doors. I was actually trying to create a magnetic chalkboard surface on my children's bedroom doors. For all of the hassle and tediousnes in the process, I would have been better off buying pre-made magnetic chalkboards and mounting them to the doors. The surface is magnetic and attracting magnets, though.

Great product and second time I have used it.

Very thick and heavy paint, took as much mixing as the can recommends. Likes to stick to itself during application, it wasn’t easy to get a smooth coat. But it is magnetic so that part works fine.

It was chunky and did not go on smooth after stirring and did not magnetize well.

Works exactly as I expected! Made this home quarantine project a success.
