Can I sleep in my room after and some other questions about cleaning up mold.

Hi so I bought some foam mold remover for the windowsill in my room since it is covered in black mold.

I have some questions, firstly being will I still be able to sleep in my room if I clean the mold at like 7am? 8am?

Second question is would I be able to sit in my room for some hours after?

I have building work downstairs so I have to stay in my room till 3pm. I can go out for like 1 hour tops but have dogs in the other room to make sure they don’t escape so mostly need to sit in my room.

I’m not sure what to do about the situation but I’m having someone over at the weekend and want to show them my room but I’m embarassed about the mold.
