Clean/fresh DE sloughs off of the grids too. The nylon fabric in a radial style DE filter is probably a little bit better than the polypropylene material used in vertical cartridge style DE filters. But it all sloughs off when clean. My procedure is to clean and recharge my filter but then I run my pump for 24 hours straight after cleaning. That way the DE coats everything and is more likely to pick up enough particulates to make it stick better. As was posted above, dirty DE tends to stay stuck on.
I doubt there is any harm during startup. The in-rushing water into the filter instantly kicks up the DE on the bottom and the filter material will be coated within seconds.
