Black Spots On Bathroom Ceiling

Sand down the ceiling. If your ceiling is discolored or you plan on repainting the ceiling then you should sand down the ceiling. Sand the areas where the mold was covering to remove any lingering traces and provide a good base for the new paint. If you need to repaint the whole ceiling, for example because the paint colors will not match or it will show the area that was re-sanded, you must sand the entire ceiling.

Mold spores will grow in damp, humid conditions. Showers and bathtubs tend to produce steam, which rises to the ceiling and settles there in poorly ventilated bathrooms. It is rare that a ceiling gets dried or that it is exposed to sunlight, so spores begin to grow. To avoid the accumulation of mold spores, it is vital to circulate the air when the shower or bath is being used, especially if the weather is hot and humid. Be sure to open any windows in the bathroom when you are showering, even if it is just slightly. A bathroom ceiling fan or room vent would reduce a great deal of the moisture in the room. Another solution would be to consider using a mold-resistant paint and covering the entire ceiling for protection.

Have you worked at cleaning mold from bathroom ceiling spots only to have them surprise you by coming back? To really get rid of mold, you have to not only clean it away, you must also kill it. In problematic cases, it may even require replacing ceiling tiles or sheet rock.

The spots are dark brown (perhaps black), and small. I’ve wiped them clean once before, and they’ve returned (thus I assume it’s mold). There are about 10 small spots.In addition to the test kit, what are some general preventative measures to limit the formation of mold in shower areas?

The most common place for problem black mould is in the bathroom, occasionally in the bedroom on or around windows, sometimes in cupboards, wardrobes or behind beds. Here are pictures of black mould in the bathroom but to see other common places for black mould please see the condensation page.

I would not bother testing it – undoubtedly mold or mildew – same diff. Usually starts up near the ceiling, in the back corner of shower/tub enclosure, and along exteriro walls in the winter, where moisture condenses on the colder wall. Clean well by scrubbing with TSP and washing off, then wash well with 50% chlorine bleach and water (regular laundry bleach like Purex), holding the wet rag on the general area where the spots were for about a minute, then wash off with fresh water. If the spot is damaged (not smooth paint) then apply Kilz paint, followed by your finish color paint with a mildewcide powder mixed in per instructions (available where you by paint). Most household interior paints do NOT have mildewcide in them, so they pick up mildew quickly. Prevention – washing walls down with a capful of bleach per gallon of water and detergent monthly to remove the dust and lint that the mold comes in along with (always mold spores in the air) and grows on, and keeping your moisture level down. Run the bathroom fan from the start of the bath or shower (and when washing walls) NOT from the end, and leave running for about 1/2 hour + afterwards with the bathroom door open – more on humid days when the water does not evaporate off the walls and mirrors quickly. Leave shower doors open while doing this, so moisture in the tub/shower enclosure can circulate out and be gotten rid of.
