So, first you need to dismantle the old coating: paint, wallpaper or ceiling tiles. Even if you did not notice the fungus before, its spores can successfully live in the thickness of the old coating, and then, after repair, with the same success multiply and spoil the already new repair.

After dismantling, you should tap completely the ceiling, fixing for yourself those places where, when tapping, a sonorous sound is heard. This is already the reason to remove the layer of plaster or putty. Otherwise, it will soon fall off by itself.

Next, you need to brush the ceiling with a metal brush and cover with a special primer that contains a strong antiseptic against mold. This is perfect not only to prevent the appearance of fungus on the ceiling in the bathroom, but also to destroy the already existing tiny pores. Experts at the same time advise priming the ceiling several times, without regretting the means.

Then restore the normal smooth covering of the ceiling in an ordinary way (with the help of mortar and putty). When all this grasps, again cover the surface with an antiseptic primer. And only after its full absorption can be safely taken for the basic decorative finish of the ceiling.

Very often there are cases when the repair is already done, and after a while a fungus appeared on the ceiling. What to do in this case? We must act as quickly as possible. So you will be able to maintain the old decorative cover as much as possible during the fight against mold.

Surface preparation

So, first you need to protect yourself from mold. To do this, use a respiratory mask and good rubber gloves. Wear unnecessary clothes, which then do not mind throwing or washing in a disinfectant solution.

Before using the product, you must carefully prepare the surface of the ceiling.

The preparation process itself will depend entirely on the decorative coating on it and how much it is already affected by visible mold.

So, if the ceiling wallpaper or an oilcloth, then in the affected area and in a radius of about 10-20 cm around it should be torn off the wallpaper. Do not feel sorry for them, because you can put a new piece of cloth in this place. Rip off gently so that invisible spores do not scatter around the room and do not hit the walls.

After this place, where there was a piece of wallpaper, it is necessary to clean well with a brush for metal. Previously, the brush is wetted with an antiseptic agent so that the spores do not scatter to the sides. After the brush has dried, it will be possible to start the fungus removal process.

In the case of a painted ceiling, everything is a bit simpler. If the surface is not slightly affected, then it makes no sense to rip off all the paint. You can wipe a place with a damp, hard sponge, affected with a fungus, then brush it with an additional brush and allow to dry.

Molds of molds

Means from mold: soda, vinegar, sodium solution, citric acid.

If it is a ceiling tile, then it is important not to miss the moment when the mold is just beginning to develop. Otherwise, you will have to completely remove all the tiles and check their reverse side for lesions. In any case, you will have to remove several tiles.

The places where they were are brushed. The same tiles that are affected by the fungus can also be cleaned, neutralized with the main method and then glued again if they are expensive and throw them away pityingly. Only carefully clean the side seams before processing, since it is in them that most of the mold accumulates.

Quite simply, everything with a ceiling that is covered with decorative plaster. If it is normal, you do not need to rip off anything. It is enough to make a similar brushing, drying, then you can safely remove the fungus on the ceiling using the basic methods.

Only then, at the end of the process, you may need to restore the hue, if there was colored plaster.
