Bathrooms are highly stressed rooms. They have to cope with strong fluctuations in humidity. In addition, they must be easy to clean, otherwise the visit to the bathroom quickly becomes an unappetizing thing.

Plaster the bathroom

For this reason, the tile flooring in the bathroom has become largely standard today. However, the tiles can not simply be glued to the masonry. You need a perfectly level surface so that you form an equally straight tile mirror. Although it is quite possible to build the tiles with a thick layer of mortar directly to the wall. But this technique dominate today only the older tile masters.

It does not always have to be the tile

However, many homeowners do not really like the "bathroom tile obligation". They are looking for alternatives. The good news is: You can also plaster a bathroom. A plaster covering offers many creative possibilities. Above all, it frees from the always same rastered surface, which inevitably brings a tiled surface with it. However, when plastering a bathroom, a lot to note, otherwise the joy is short-lived.

Theoretically, everything is possible

Theoretically, any type of plaster can be used in the bathroom: lime plaster, loam plaster, gypsum plaster, cement plaster ... the building materials do not play a role in theory. However, this only applies if the homeowner scrupulously takes care that the bathroom is always dry. So if the bathroom has an automatic ventilation and underfloor heating, then you can safely assume that it always remains free of moisture. However, this can not be guaranteed with every bathroom.

Wall and floor covering

Practically severely limited

The problem with damp plaster is mold. In a warm humid climate, which offers a bathroom, the mold has excellent living conditions. Because of lost hair and dander, there is also an interesting food supply in the bathroom, the growth conditions for the mold are ideal. For this reason, the tile has become so prevalent as a wall and floor covering for bathrooms: The smooth, glazed surfaces do not provide a breeding ground or primer for a mold spore.

A plaster for the bathroom must therefore be able to cope with this challenge. The less moisture-resistant plasters are therefore unsuitable for the handyman for the bathroom.

Non wet strength plasters are:

  • clay plaster
  • lime plaster
  • gypsum plaster

All of these plasters are wonderfully easy to work with. The constant attacks of the wet and the mold, however, make them crumbly and brittle over time. Plaster or lime plasters are therefore only suitable for flushing a tile mirror in the bathroom. Through the tiled surface, they are then well protected against moisture. For a decorative plaster in the bathroom is our recommendation therefore: cement plaster and nothing else.

Cement plaster is ideal but not perfect

Cement plaster consists of Portland cement and sand. It is mixed in a mixing ratio of 1: 4. We recommend to use fine quartz sand . The smaller the grain, the smoother the surface can be executed. A smooth surface in the bathroom is very important. After all, you stay there mostly undressed. A sharp, rough plaster is thus always a risk of injury. With a fine addition and a good, smoothing processing this danger is banned.

Cement plaster is not as easy to apply as lime or gypsum plaster. He just reluctantly applies and straightens. This problem can be improved by the addition of an additive. This addition also serves to make the plaster particularly waterproof. Instead of mixing the cement plaster itself, it is also possible to use ready-made plaster for the bathroom from the hardware store. Especially for home improvement this is the more practical solution.

Process cement plaster

The plaster for the bathroom needs the following materials and tools.

  • a big mortar trough
  • a powerful drill with whisk
  • water
  • Plaster in sacks
  • Putzer trowel
  • trowel
  • Putzer strips
  • smoothing tool
  • spirit level
  • primer
  • Quast
  • Putzer tissue
  • bar
spirit level


It is important to wear protective goggles when mixing and applying cement plaster . Cement gets in the eye, a doctor must be consulted immediately. Cement in the eye is very dangerous and can lead to blindness.

First, a little plaster is mixed in a bucket with the trowel. With three blots each, one at the top, one at the bottom and one in the middle, the blower strips are fixed to the wall. They are then carefully aligned with the spirit level, so that they stand exactly straight.



During the time in which the cleaning strips tighten and harden their bonding mortar, the wall is coated with the puff with primer. When the primer and moldings are firm and dry, the first layer of plaster is thrown against the wall. Now the layman must wear safety goggles, because this is a very dirty job.

If a thin coat of plaster hangs on the wall, the cleaner fabric is pressed in. It gives the whole cleaning mirror an inner hold and prevents cracks from forming. The cleaning cloth should be in the center of the finished plaster layer. The plaster may now be irregular and rough. This is even optimal for the hold of the top layer.


Now the cover layer is thrown up. By raising the cavities are closed and the maintenance of the plaster improves. It is done train by train. The space between two Putzerleisten is a train. It must be smaller than the bar is long, so that the surface of the plaster for the bathroom can be deducted well. After the plaster is started, it is still pulled off in the soft state. So you let it mature for about 15 to 30 minutes.

After the plaster is put on something. he is rubbed off with the friction board . It is important to hit the spot: the plaster needs to be damp, but at the same time already hardened. By rubbing the slurry is shaken by the capillaries to the surface. The slurry closes the pores and thus allows perfect smoothing of the plaster covering.


After rubbing, finally, the smoothing with the smoothing chip comes. After curing, a mirror plaster is ready for the bath. He can now be creative at will.

Upgrade the mirror plaster

The usual method is to tiling the wall after applying the mirror plaster . But let's see what options there are for plaster for the bathroom. Although a structure plaster can indeed be applied directly to the masonry by professionals. But as a home improvement you should always start with the mirror plaster and then continue to work ahead. Ideal for creating a structure-plaster surface is the rolling plaster . But be careful - be sure to buy the plaster for the bathroom, so that the rolling plaster also holds.

roll Putz

Rolling plaster is basically nothing more than a thick paint with a surcharge. The structure gets the rolling plaster by the choice of the role . Before applying the rolling plaster, the wall should be painted again with primer. So the rolling plaster keeps safe.

The application of Rollputz hardly differs from the painting of a wall. All you need is a bucket of roller trim and a roller. The structure of the roll determines how the rolling plaster looks on the wall. The trade offers many variants. Creativity knows no limits.

Painting and sealing

Roll plaster as plaster is white in itself. If a bathroom plaster is used, it is already moisture resistant and does not need to be additionally sealed. However, if the wall is to be painted, an additional seal may be required.

Otherwise the mold spores and the bacteria have it easy again, as in the case of lime plaster, to settle and settle. By using a waterproof paint, a protective seal can be saved. But beware - a waterproof paint can be very solvent-based. The bathroom must then be thoroughly aired for a few days after painting, before you can use it.
