Likely a very dumb question so indulge me

I saw on Pinterest taking a oil pan (for under the car) and making a magnet board out of it...

I plan on doing that for the backyard play area and nailing it to the fence.

I plan to have 2 one plain with magnets and another I was thinking of painting with chalkboard paint over it.

So does chalk paint unmagnatize the pan? or can it be both a chalk "wall" and a magnet "wall" ?

curious...

these will both me removable for unpleasant weather conditions Smile

TIA

The chalk paint should not 'un-magnatize' the metal, however, depending on how thick the paint, it could make it the magnet effect weak.

i agree with mel although i don't know that for sure

i do think the can stated that if you were painting metal to prime first....but i could be wrong about that too :ROF:

I agree with Mel, it'll still be magnetic, but weaker.

It's going to depend on the strength of the magnets you are using. Think about when you try to put too many things under a fridge magnet and it falls off. But, I'm just guessing at this, it may not effect it at all. KWIM? And FWIW, the metal doesn't lose it's ability to have a magnet stick to it, that is the magnet's properties.

i could be totally wrong here but i think you may be more worried about the paint causing a barrier between the oil pan and the magnet....not that the pan will lose its abilty to stick.....

lol...not that it matters.....it means the same thing ROFL

carry on

I used the chalkboard paint over the magnetic paint and it was still a bit magnetic, enough to hold one piece of paper on, and that magnetic paint is [EMAIL=cr@p]cr@p[/EMAIL], you need a ton to make it semi magnetic and then I painted a few coats of chalkboard paint over it. I would think that it would be fine. Also if you have to prime it, you can use that magnetic paint as it is a primer as well. Since you're already working with a metallic surface, you'd only need a coat or two of the magnetic paint.

I made the cookie sheet with a paper cover magnet thingy... paper totally made it weaker... I would assume a few coats of paint may do the same...
( I also used dollarama magnets so a stronger magnet might have been smarter)
