Mechanical and chemical cleaning methods + Video Currently, brick decoration of country houses is very common. The brick finish gives the building an aesthetic appearance and looks quite expensive. However, the masonry is often not very attractive and has remnants of adhered concrete. And here the question arises - how to clean the brick from the mortar? It can also occur when using old material from dismantled masonry.

There are several cleaning methods.

When choosing a method, you need to take into account the nuances of the type of surface, the amount and structure of pollution. The mechanical and chemical methods are distinguished.

It should also be borne in mind that each type of brick has an individual approach to cleaning. So, for example, chemical solutions cannot be used to cleanse a silicate species from cement, since such processing will lead to its scattering.

Mechanical method

This method is suitable for almost any type of masonry brick, but if the possibility of surface damage is great, it is better to use chemical solutions.

This option is not suitable for removing small errors.

Important: When using the mechanical method for cleaning facing bricks, it is important to be extremely careful, since, unlike masonry, this type is more fragile.

In work, use tools such as a metal brush, trowel, hammer. For small growths, use brushes, and for massive ones, it is better to use a heavier device.

Note: Before work, the brickwork is wetted with water.

This will help soften the building mix and make the process much easier.

To exclude the application of incisions on the brick, blows are applied along the surface. After breaking off large pieces, these places are processed with sandpaper. During mechanical cleaning, it is important to take into account some rules to prevent undesirable consequences

To clean silicate and ceramic bricks, you need to use different methods because cement on silicate is much stronger. To clean the bulk slaps of silicate and red bricks, use a drill, perforator or grinder.

If the cement layer is small, it is better to use a sander.

Chemical cleaning

This method can be used to clean red and ceramic bricks. You need to carefully select a cleaning solution that matches your type of brick, otherwise material damage may occur.

Chemical cleaning is performed in the following sequence:

  • Preparation of the composition;
  • Application;
  • Waiting for time ;
  • Removal of solution residues.

As a rule, all cleaning solutions contain an acid.

The only difference is in concentration and application conditions. Dissolved hydrochloric acid or sulfuric acid can also be used in a ratio of one to ten.Application is carried out on a pre-moistened surface, after a while the residues are washed off with water. If the cement lumps are large, give more time to soak and then remove the softened residues.

Important: When working with acids, protective equipment should be used to prevent contact with skin and respiratory organs.

Cement smudges from ceramic bricks are cleaned with sulfuric acid. Wet surface, gently wipe off with a cloth soaked in acid. Unmasonry bricks can be boiled in acid. For this, a cast-iron container is installed above the fire, into which the material is folded, filled with an acid reagent and boiled until the cement is completely dissolved. After that, the material must be rinsed well.

Cleaning with water

Cleaning with water can be dangerous. Under the influence of dampness, the brick can become covered with mold, which is very easy to wash off with a water pressure. But after a period of time, the spots may appear again and even become larger.

The fact is that the fungus, along with water, gets into the smallest cracks on the brick. And the way out here is to cover the surface with an antiseptic solution.

Universal methods

Brick chips mixed with sunflower oil can also be used. It is rubbed into the bricks after laying and left to dry. Then the growths are cleaned with a stiff brush. You can take any chemical for the car, apply to the wall, let dry and rinse with water under pressure. After any of these methods, you need to fix the result using a water repellent.

It will protect the brick from moisture.

There are many cleaning methods, but if you combine different methods, you can achieve a high quality result.
