Chalkboard
TomC1950

My son is using a 4' x 4'piece of sheet metal to use as a chalkboard. He will paint it with the necessary chalkboard paint. We're looking at using either a 1/4" piece of Masonite or plywood for a backing. I'm wondering what would be the best mastic to use to adhere the sheet metal to the backing. We will clean the sheet metal with acetone to remove any oil any film. Any ideas?

Here is a good idea:

- Find a wood picture frame at a size you desire (they come in easy standard sizes, pre-assembled, joined and fastened). If you can't find it in 4'x4' you can have it custom build at a frame shop.

- Place the frame up side down on a work bench, then place the sheet metal in and finally the backing over construction glue - Masonite or plywood will do. Staple around them into the frame to hold them together.

Viola.

Caution: it may be heavy.

Contact cement will be the best thing to use, as it goes on like paint.

Just curious, unless it needs to be magnetic, why metal for the chalkboard base and not just use the masonite itself? Also, for what you're going to spend in materials, have you priced chalkboards in the size you're looking for?

I don't know what his thoughts are. He has the special chalkboard paint. I'll run it by him and let you know.

My daughter-in-law wants the chalkboard to be magnetic.

That's not much to ask...

No problem, thanks for the update, I was just curious.

Hi TomC1950,

When you read the specs for Rust-Oleum Chalkboard Paint, the list of surfaces includes metal.

In addition, Rust-Oleum Magnetic Primer lists metal as a suitable surface.

Suggest that your son add several coats of the primer to promote adhesion of the Chalkboard Paint.

Backing Adhesive: Contact cement ... apply to both surfaces, allow to sit open for ten-minutes, and then position and stick exactly where you want the backing. This product will not allow you to re-position once stuck.

Hope this helps!

Boy oh boy are you in for a bashing. Hope your training (and mental health insurance coverage) covers that because you'll need that here :rolleyes:

If you intend to hang objects of considerable weight with magnets, stick with the plan to use metal sheeting. The magnetic paint does work for hanging small kitchen magnets, but won't hold heavier objects. The magnetic paint also requires at least three coats to get enough mass for the magnets to work at all.

Pat in Paint,

Glad to see you on the TOH site. You are going to get quite a razzing from the old timers on this site. Home Depot is not held in overly great esteem by many tradesmen. I have never hidden the fact that I work at HD from the regulars on this site. For the most part, I have gained their respect after several years of contributing.

I have been off the TOH site for several months, but will now be again be a regular contributor.
