Monday 23 August 2021

Moisture problems are a challenge for any building, but especially in your own home it is a situation you want to avoid. Fortunately, there are ways to combat moisture in your home, such as impregnating your façade!

The impregnation of a facade is a delicate job that is best left to a professional. But what are the advantages of impregnating your façade, why should you let a professional do it and what can you expect in terms of price? Such questions are clearly answered in the overview below!

What is façade impregnation?

Impregnating a wall means that a substance is introduced into the wall or façade that prevents moisture from passing through. The substance used is also called impregnation and it is always a water-repellent substance. The benefits of impregnating your facade are far-reaching. Many people have questions about the process, the why and the price of impregnation - and that is what this article can help you with!

Why is it such a good idea to impregnate your façade?

There are various advantages and functions to impregnating a façade. One of them is that it makes the wall moisture-repellent, so that you no longer have any moisture problems in the house.

The causes of dampness in the house can be various:

- Moisture rising from the ground
- Moisture from outside

Impregnation only helps in the latter case, however, and that is because the impregnation agent penetrates deep into the treated material. This can be stone, but also wood. In addition, the agent will also seal the pores of the material, which are there by nature. In this way, moisture cannot find its way inside!

The functions of impregnation are listed below:

- The wall becomes water-repellent
- The wall becomes mildew-resistant
- The wall itself is water-repellent
- The outer walls are more resistant to fire because the impregnation agent contains a fire-retardant substance
- The walls are better protected against acid rain
- Thanks to the extra stomach on the wall, it will be better protected against graffiti.
- The risk of damage by frost in your home is a lot smaller

So there are more than enough reasons to have your facade impregnated by a professional. Of course, deciding that you want to protect your façade or wall against moisture is only the first step. In the next section you will find more information about the average price you can expect for this work!

What are the disadvantages of impregnation?

Impregnating your façade clearly offers a lot of advantages, even in financial terms. But does that mean there are no disadvantages to this method? In itself it does, so it is important that you take this into account if you want to call in a professional.

Here are the most important disadvantages of impregnating your façade:

1. The wall ventilates less well

Because the wall is, as it were, sealed with the impregnation agent, it will not be able to ventilate as well. This can have an effect on the indoor climate of the house.

2. Moisture trapped inside

Because of the good insulation, moisture that is already present in the house will be less able to escape. This means that you will have to tackle existing moisture problems immediately.

3. Impregnation can be expensive

Although the basic price of impregnation is low, it can still be expensive. For example, if the facade has cracks, gaps or porous masonry. These will need to be repaired or replaced before you can impregnate your façade.

4. Impregnation has a temporary effect

Finally, impregnating your façade is a temporary solution. The impregnation agent only retains its effect for a few years, so you will have to have it re-applied regularly.
