Whitewash for the ceiling: types

When whitewashing the ceiling, first of all, you need to decide on its appearance. The choice is usually based on the cost of the materials used, the type of old coating and the complexity of applying a new finishing layer.

There are three types of whitewash common today with:

Chalk, lime and water-based paint – the main types for whitewashing the ceiling

The latter kind of literate would be called painting, but for simplicity, it can be attributed to the concept of whitewash. Chalk and lime whitewashing are more environmentally friendly methods, but chalk tends to crumble, and some people are allergic to lime. Aqueous emulsion paint gives the ceiling a more aesthetic look, but after such treatment the surface does not “breathe”.

It is important to know that it is impossible to whiten the ceiling with lime if the old layer is treated with chalk, and, on the contrary, it is not allowed to chalk the old limestone layer, as there will be ugly divorces.

For whitewashing with chalk, you need to prepare a solution of 3 kg of chalk and 30 g of wood glue, which must be mixed in 5 liters of water. It is better to use warm water to better dissolve the powders in it. Blue can be added to this mixture, as it will make the ceiling snow-white. The amount of blue will depend on the desired shade of the ceiling. In these proportions, 15–25 g of this substance is recommended.

To lime the ceiling, you need to prepare the solution as follows. About 2.5 kg of lime must be diluted in a liter of warm water, 100g of salt, previously mixed in water, is added to this composition. Similar to the chalk solution, blue is added to this mixture. After all procedures, the resulting concentrate is diluted with ten liters of water.

If you applied the previous whitewash with chalk, then the next one should be made of this material.

Aqueous paint is purchased in the store already finished. It should be noted that the consumption of such paint is large enough, and the shades can be different, therefore, to avoid spotting the ceiling, you must purchase paint with a reserve in advance. This type of treatment is best used for the bathroom, as the painted ceiling can be washed. To get the whitest ceiling you can cover it with acrylic paint Snowball, and you can paint the ceiling with different colors.

Apply whitewash on the ceiling plate should be in 2 or even 3 layers to completely cover the previous layers. In this case, the first layer should be applied perpendicular to the sun rays coming from the window, and the second one parallel to them. Apply a new layer with a brush or roller only after completely drying the previous one. If the technology is broken, then bubbles appear.

Whitewashing ceilings: stages

Ceiling whitewashing is not such a complicated process as it may seem at first glance. The main thing – to act logically consistently, so as not to miss anything important.

Each stage before whitewashing the ceiling is very important, as the quality of the whitewashed ceiling will depend on it.

Therefore, for simplicity of the repair process, the following steps of whitewashing the ceiling can be distinguished:

  • Determine the type of old finishes (hold your finger on the ceiling, if white traces remain, then chalky, if there are no traces – lime;);
  • Decide on the removal of old layers;
  • Check the strength of the old coating, when deciding to whiten on the old finish;
  • Remove all poorly attached layers of the old layer;
  • Properly seal up any irregularities, cracks and cracks (the mixture is applied with a spatula perpendicular to the crack, and then the excess is removed with the same spatula, but in parallel, you can use shpakril);
  • Wipe all irregularities with a pumice or sandpaper after the putty has completely dried;
  • Remove all contaminants depending on their type;
  • Treat the entire work surface with a deep penetration primer;
  • Select the type of whitewash based on the type of old standing;
  • Prepare pobelochnaya mixture or buy water-based emulsion in the store;
  • Apply several layers of whitewash on the ceiling.

Carrying out the process in stages, the whitewashed ceiling will turn out beautiful and clean.
