I bought medium-dark blue semi-gloss paint for a bathroom in my house, but due primarily to the old plaster's uneven nature, the darker color with a semi-gloss paint does not look great. You can see all of the imperfections in the plaster with the gloss in the paint.
I bought semi-gloss because I always thought bathrooms needed a semi-gloss for cleaning and due to the moisture. This bathroom has a window but no fan ventilation so I thought a semi gloss was definitely needed.
Is this the case, or can I get a flat paint instead for this bathroom even though the wall will get some dampness regularly?
