I have mistakenly mist coated my bedroom with silk instead of Matt. The walls have covered and dried fine but the ceiling is taking ages to dry, and if I touch it, it just pulls it off back to the plaster. It feels more like a gloss. Is there anyway to retrieve this situation or do I have to start again?
Forgot to say that I have first coated the ceiling after the mist coat and about 20% of it is just not taking.
