A couple of startups I've worked at over the years did this. Couple of observations:

The coating doesn't seem to be quite as thick. Perhaps a few coats of whiteboard conditioner before starting and at intervals would help.

If you don't put a faux border on it, then you get whiteboard ink dust on the walls and it looks kind of trashy. I speculate that your best bet would be to get a bunch of trim with a rabbet in the back, bolt the bottom piece to the wall, have someone hold the board in place while you bolt the top part on to keep it from shifting. Hide a couple of screws through the boards along the sides to make sure it doesn't buckle on you.

I have 4 of these, for about 9 yrs now. Doesn't look trashy, nor do I have ink dust on the wall. Didn't bolt either. Used the velcro glue thingy.
