Wash brick facade and wall with high pressure wash

Wash brick facade and wall with high pressure wash


New homeowners are less likely to see how the brick facade, the brick wall wall or the wall at the balcony suddenly begin to become whitish, and one immediately asks: What's wrong with the brick? In addition, if you have done the masonry work, perhaps without a larger routine, the shock will be in panic. What mistake have you made? How much will a renovation cost? Must the job be done??

Take it easy, though. It is usually water-soluble salts in the masonry that have deposited in the surface. In the vast majority of cases you can brush yourself or wash them! Damage to this battle is natural in its own way. One of the tasks of the brick is to prevent moisture migration inwards, for example, in a wall. It also makes the message available. A swirling rain against a brick wall can penetrate into the inner parts of the wall, but almost unavoidably depends on the unevennesses in the mortar joints. After burning, the brick is very dry and of comparable materials it has the lowest so-called hygroscopic moisture content. It is therefore less moisture absorption than other materials. This also means that dehumidified brick dries out very quickly, as a result of the capillary suction striving to level the moisture content.

The water that is also found in the brick, thus, reaches to drier surfaces to evaporate from them. And with the moisture, the salts follow both brick and use. The fact that the process is natural does not mean that you can or will accept it. On the other hand, as said, there is rarely any reason for panic acts. First of all, it is not uncommon for the precipitations to cease by themselves. Secondly, you can accelerate the salt walk and thus get rid of it. If you choose the "self-healing" procedure, it is not uncommon for you to tolerate your mind for a few years, sometimes even longer.

Such a long wait can of course be difficult to accept, not least because the precipitation is ongoing. As a consequence, the sprawling white spots will only get bigger and more prominent. It is then possible to basically choose two treatment routes. Either dry brush the tile surface and take the vacuum cleaner up with the salt that dissolves or wash with plain water. Outdoors, you have a great deal of benefit from a high pressure wash. There are smaller such appliances for home use. However, they cost a lot, but can often be rented on, among other things, construction markets.

Warning

It is the tile surface and not the joints that are discolored by salt deposits. Excessive treatment can damage the joints. Sometimes recommended hydrochloric acid for brick washing is recommended. Never use this without expert instructions. Brick can absorb laundry solutions. Never wash bricks in the sunshine or when there is a risk of frost. Use gloves and goggles for high-pressure spraying.

Tips

A gray-flame discoloration of the tile surface indicates that residues of brick have remained on the brick, which is a lack of masonry technology. When flushing a brick wall after washing, the chance of disposing of the deposition particles is greatest if you first swirl downwards and upwards and then in the opposite direction. Salts may require repeated washings before they are fully painted.

Worth knowing

If the described cleaning after several repeated attempts does not work, harder roof may be necessary. However, in order to choose the correct method, the precipitation must be analyzed. Ask the brick supplier where to turn. For the analysis, you can scrape about a teaspoon of salt from the wall with a knife, put the scraper in a plastic pocket or match box and seal well.

Here you need to wash a tile wall or wall:

Not too hard brushes with and without a shaft. Washbasin, Water tank, High pressure syringe, Vacuum cleaner, Knife or filler for sampling.


1.Pack the floor with protective plastic and tape it so that it remains. Add moisturizing newspaper on top.


2. Occasionally, it is enough to dry the surface or just vacuum it. Soak up salt dust at any rate ...


3.If you want to use water, suck a moderate amount into a sponge, wash, allow to dry and brush.


4.Wash with long brush in small circular movements. Be careful not to use the joinery.


5.Washing downwards and upwards, hard and shining. Let the tile dry and repeat the treatment after a few days.


6.Use the high pressure wash, set the pressure. The high pressure wash can give about 25-50 times higher pressure than the tap.
