Ceiling whitewash in the bathroom

Ceiling whitewash in the bathroom

Whitewashing is the most traditional way to maintain the cleanliness and whiteness of the ceiling. For many centuries before us in Russia whitewashed huts a special mixture based on limestone. Lime - an environmentally friendly and completely harmless to human material. It has disinfecting properties, which is especially important for a bathroom, because high humidity is the most favorable condition for the appearance of fungus and the reproduction of bacteria. In addition, this type of coating is good for air and absorbs moisture.

Whitewash the ceiling

To whitewash the ceiling is very easy, in the bathroom it can be done in just a few minutes. As a result, with minimal effort and money, you will get a fresh, beautiful ceiling covering, which, if necessary, can be updated very quickly.

Of course, this method has its drawbacks. First, the whitewashed ceiling needs to be refreshed from time to time, because, covered with dust, the lime quickly loses its original whiteness. Secondly, the lime coating is quite fragile, so if it is mechanically damaged or because of a poorly prepared working surface, it can peel off.

Preparation

Before you start working, all surfaces and furniture are usually covered with plastic wrap, so that they do not get a composition for whitewashing. When whitewashing the bathroom ceiling, there is no special need for this, since the lime is easily washed from the tile. However, if your bathroom is furniture and plumbing, made of expensive natural materials, it is better to be safe and cover it with polyethylene, and if possible, take it out of the room.

How to whitewash the ceiling

Next, you need to clean the ceiling from the previous whitewash layer. If the surface is fairly flat and light, then you only need to refresh the coating. To do this, it is sufficient to collect the accumulated dust with a brush or a vacuum cleaner.

If the ceiling has not been whitened for a long time, the previous coating darkened and began to exfoliate, then you will have to scrape everything down to the plaster. We do this as follows: using a spray or a wet sponge moisten the old whitewash, then collect the soaked lime with a spatula, and what remains is washed off with the same sponge. Do not apply too much force, otherwise on the plaster there will be scratches and dents, which will have to be closed.

Primer for whitewash

When the ceiling dries, treat it with a primer. The composition for priming is selected depending on the material that we will use for whitewashing.

Material selection

Usually for whitewashing the ceiling use lime, chalk or water-based paint. We already spoke about the advantages of lime above. Characteristics of the chalk are almost identical. The advantages of whitewash with water-based paint are that it dries quickly, it is easy to clean and it falls well even on unprepared surfaces.

Water-based paint for ceiling

However, for whitewashing the ceiling in the bathroom, experts recommend using acrylic based paint. This paint is excellent for use in rooms that are characterized by high humidity and temperature changes. Some manufacturers add to the composition of acrylic paints components that prevent the occurrence of mold and fungus. True, the ceiling coating with acrylic-based paint will cost you significantly more than the traditional whitewash with chalk or lime.

  • about 3 kg of slaked lime;
  • 3-4 tablespoons edible salt of coarse grinding;
  • 0.5 kg of the diluted dye;

In order for the chalk whitewashed to look even brighter, before applying to the ceiling, a little bit of blue is added to it. The result is a white-white color with a barely noticeable bluish tint.

Necessary tools and devices

In addition to the large capacity and the device for mixing the solution, you will need a stepladder for whitewashing, or a stable stool if the ceilings are low, several brushes of different sizes, a paint roller or a vacuum cleaner with a nozzle-sprayer.





Tools for whitewashing

Work is necessary in safety glasses, because the composition for whitening can severely damage the eyes. Put rubber gloves on your hands and hide your hair under the headdress. Protect the respiratory tract with a respirator or an ordinary medical mask.

Application

So, whitewashing on the ceiling can be applied in three different ways:

  • Using a paint brush. For the basic work you need a brush with a width of 20-25 cm, and hard-to-reach places and corners can be smeared with a brush. If the handle on the brush is not long enough, attach it to any light stick (for example, from a plastic squeegee). Work with the brush back and forth, moving it in one direction. After the first layer of whitewash dries, apply the following. The second layer must be applied perpendicular to the first.
  • Using a roller. It is much more convenient to work with a paint roller, since it distributes the paint over the surface with a thinner and even layer. If you prefer to work with a roller, then you will need a paint tray. Pour a little solution into it, dip the roller and begin to apply whitewash to the ceiling with wide movements. You can work in different directions, most importantly, make sure that the coating is uniform.
  • Using a vacuum cleaner. You will need a spray nozzle, which is also called a "spray gun". To do this, you need to select the operating mode, in which the length of the jet will be about a meter. Set the pressure to 3 or 4 atmospheres. Whitewash on the ceiling should be applied in circular motions, avoiding streaks. If necessary, a second coat can be applied.

To achieve a perfectly smooth coating, you can combine the first and third methods. The first layer of whitewash apply with a paint brush, and the second - with a vacuum cleaner with a sprayer.

Advice

  • To ensure that the coating is as uniform as possible, do not limit yourself to a single layer of whitewash. The optimum number of layers - from 2 to 4. In this case, each subsequent layer should be applied on a completely dry surface.
  • During whitening, keep an eye on the location of the lighting fixtures. The first and penultimate layers of the coating should be applied perpendicular to the light source, and the latter - in parallel. In this case, the marks from the roller or brush will not be noticeable.
  • The coating will be durable and will not lose its original appearance for a long time if you let it dry yourself without using heaters, fans, hair dryers, etc. Also it is necessary to protect a freshly beaten ceiling from hit of solar beams, the truth in a bathroom is not a problem.
  • If the last time you bleached the ceiling with lime, then next time you can not use a different kind of coating, and vice versa. Only lime can be applied on top of the lime, and only chalk over the chalk. Otherwise, the ceiling will be covered with ugly stains and divorces.
  • If the snow-white ceiling is not to your liking, you can add color pigments to the whitewash, achieving different shades. So, to give a greenish tint to the coating, chromium oxide can be used. To give a milky or beige shade, a burnt sienna or umber is usually used - natural natural pigments. Ocher helps to achieve the color of ivory, and the roan - pink and reddish shades.
