Hi,
I will be painting a bathroom that has a textured design at varying
angles on the walls like this: �((((( � � � and currently has a semi
gloss paint finish. I would rather not use a deglosser as the room is
not well ventilated. Is there a way or tool I can use to lightly sand
the paint and get in the crevices of the texture so the new paint
(also semi-gloss) will adhere properly? �Thanks.

add fans wash with TSP rinse twice, then prime well with oil based
KIlZ, then paint normally.

Good time to add a exhaust fan if you dont already have one, vented to
the outdoors.

high humidity leads to mold growth and paint peeling
