Still wet after 20 hours?? Anyone else experience this?

Depends on temp. but should be dry within 20 hrs. However if it waservice for proper advice.s applied to a moist surface perhaps this affects the drying cycle, suggest you contact manufacturer

I'm not sure but if you can use it over roofing felt I would guess that you could

Yes, it can as long as you manage to flatten it down again
