Q:

Chalkboard-alike wall for children

I was thinking about converting a wall in one of the rooms into an improvised chalkboard similar to these. The idea is to cover it with a charcoal-close interior paint.
It has to meet a few key criteria:

Safe for kids. Obviously. They are the primary users of the thing.
Durable [mechanical wear], i.e. be thick and hard after it dried out; at least harder than chalk so that the active contact does not destroy the color/paint.
"chalk friendly" texture so that it's actually usable within the bounds of desired application.

The other criteria are more of nice to have, but way less important.

Durable [water impact], i.e. splash-resistant at least to some degree. Kids and myself are known to be not super-precise in movements, water on the wall is expected once a season. It would be nice if such situation does not ruin the chalkboard instantly.
Easy to find, replenish, and re-paint -- I am not expecting even the most durable paint to last forever.

How do I find and "assess" such a paint [if it at all exists]? So far I found the one on the picture below, but I don't know about it much, nor about any other paints available on the US market.

P.S. I'm very open to criticism targeting my idea itself as well. You may add it to the answer, or post a comment under my question.

A:

Having met a few attempts to use chalkboard paint (couldn't tell you the brand) I'd strongly suggest looking for a (used/surplus, assuming cost is a factor) chalkboard, it will work much better. Somewhere within 50 miles of you there is almost always a school being either remodeled or abandoned; or you can leave that part to an architectural salvage firm and buy from them (it will cost more.)
If using the paint, I would suggest applying it to a sheet of tempered hardboard (e.g. Masonite®) rather than directly to the wall surface.
