To paint a cellar professionally and sustainably

When it comes to high standards - be it manual or even optical - is concerned, then the basement is always treated a little neglected when painting. But although the cellar in most houses has the rather subordinate stock function, it is of crucial importance when painting. That's why we have put together a guide for painting the basement for you.

Which type of cellar should be deleted is crucial

Although most cellars have the same function as a storage location, it is precisely these rooms that can be very different. First, you should distinguish two cellar types from each other.

  • classic cellars of old and older existing buildings
  • modern, habitable basement of new buildings

The painting of modern cellars

The latter modern cellar make the least problems. Basically, you can paint these rooms with almost any wall color. Of course, you should know the differences between such important colors as silicate, lime and wall dispersion paint (synthetic resin dispersion).

To paint a cellar professionally and sustainably: sustainably

Delete basement in old or existing buildings

With older cellars it gets a bit more difficult. To understand how these basements are usually built, you have to go back relatively far into the past. For cellars initially have a problem: they are in the ground and thus exposed to different moisture scenarios.

  • leachate
  • stagnant or poorly drained water
  • sometimes even groundwater

Basements are always exposed to moisture

Thus, these differences are particularly evident when it rains. While the soil around many houses, even after heavy and long rains in the blink of an eye, are largely dry again, other homeowners have a true marshland around them even after long periods of drought. Added to this is the fact that before the 1960s a basement seal was originally not intended.

The cellar has a central importance for domestic moisture regulation

Even then, the optimal sealing construction has prevailed only hesitantly and Neubaukellern are often worlds. For older houses, the entire house construction is actually perfectly matched. Added to this is the problem that salts are also absorbed in the masonry.

  • Moisture can reach the cellar via the cellar walls and partly the floor
  • A venting ("drainage") via the never dense basement windows, but also on the staircase
  • Walls in the living area are permeable and can regulate the moisture
  • old windows are not really tight and can also provide good ventilation
  • in the attic, the final venting takes place via the cold roof

Diffusion-open and almost sealing colors

Conclusion: the basement is part of the entire domestic ventilation system. If you were to use the usual emulsion paint in such an old building basement, this would be equivalent to sealing the walls. Already the entire moisture regulation is out of balance and the mold is not far away.

Paint lime and silicate paints to the cellar

There are also the right colors here. But if you think that these are easy to apply, that is a grave mistake. For example, lime paint is usually the best choice. The chalking and dulling of the paint can be remedied due to the addition of some linseed oil.

The meaning of the plaster

With lime plaster but also silicate paints prove time and again. However, they are relatively expensive and not really smudge-proof. But both these colors are open to diffusion and impair the moisture regulation of the basement or basement walls no further.

When painting the basement you should definitely seek professional advice

In addition, these colors have in common that they require a lot of specialist knowledge, so that they are really professionally and with lasting effect in the cellar deleted. Since there are so many different cellar constructions with no less few building materials, it is not possible to name a color system that can be performed equally well everywhere. Therefore, you should always take a specialist at your side especially in older cellars.

Tips & Tricks

Silicate paint is always a good choice, but the paint silicifies with the substrate and it can not paint over any other color systems. Instead, even a part of the plaster would have to be removed. In addition, silicate paint can not be painted on gypsum and gypsum plaster.

You may have to work the basement walls before painting with Tiefengrund, which must also be distributed in the right amount. Although the current coat of paint could also hold without a primer, but at the latest at the next or after the next coat of paint then hangs the entire old paint in the paint roller.

From the coating technique, painting from the basement is no different from other rooms. Of course, we offer you comprehensive guides and instructions, such as for painting.
