In the construction industry, brick washing, or brick cleaning is a term commonly used to describe the removal of excess mortar and markings. It is important that the last operation carried out on a construction site before practical completion looks good.
It is necessary to apply an acid mixture to the entire brick surface to sufficiently soften the excess mortar. After using a scrubbing brush to agitate the surface, the area is thoroughly cleaned with high-pressure fresh water.

When you are cleaning bricks, what should you keep in mind?
- It is important to note that the brick texture affects the effectiveness of the cleaning solution. Compared to other smears, some stains are easier to remove. Smooth brick surfaces are easier to remove stains from since there is less exposed surface area. Furthermore, they are easier to clean because residue, stains, and smears are more noticeable. Smears and stains penetrate more deeply into bricks with textured surfaces. Additionally, the uneven surface of the brick provides additional surface area for water to absorb.
- Water – Potable water should be used. Examine whether the water provider adds additives such as a water softener or other chemicals that can damage the bricks.
- Dimensions – The brick cleaner must know how big the area is. During the project, he will be able to modify the area as needed.
- A cold climate can affect the drying time of the cleaning solution and the rate at which it reacts. In general, cleaning chemicals work more effectively when the temperature outside is fifty degrees Fahrenheit. You should not clean during freezing weather or if you anticipate freezing temperatures. After cleaning has been completed, the temperature should remain above forty degrees Fahrenheit for seven days.
- Cold Weather – Cold weather speeds up the drying of cleaning solutions. If the cleaning solution is allowed to dry on the brickwork, it will leave stains and smears. During the cleaning process, the brick cleaner should ensure that the wall surface is saturated.
- Safety – Cleaning chemicals are potentially hazardous. Wear protective clothing whenever possible. Cleaning professionals should observe proper ventilation and safe handling procedures.
- Cleaning Extra Care – The cleaner should develop a cleaning plan to avoid causing damage.
Cleaning Procedures in General
New brickwork and existing masonry are usually cleaned using this technique.
- Establish a timeframe for cleaning. After brickwork has been completed, it is best to schedule the cleaning at least seven days later. Do not wait too long between brickwork and cleaning. It will become increasingly difficult to remove mortar smears and splatters from brickwork if we wait too long before cleaning the surface.
- Remove mortar clumps – Remove large clumps of mortar using wooden paddles and non-metallic tools. Rust stains may occur because of metal tools causing damage to brickwork. Smaller particles can be removed with a fibre bristle brush.
- Clean with the right solution for the brickwork condition and application – Strictly follow the manufacturer’s instructions and recommendations. Make sure the cleaning solution and equipment are compatible. Water, mild detergent, one-step chemical cleaners, and two-step chemical cleaners are recommended as the gentlest cleaning solutions.
- Protect surroundings – Safeguard the adjacent materials and nearby plants. Mark and protect windows, doors, and materials such as sealants and metals.
- Saturate with water – Surfaces must be saturated with clean water to keep them from absorbing the cleaning solution. Pressurized water cleaning should be performed at very low pressure. To prevent streaking, it is also important to wet the surfaces below the area and keep them moist until the final rinse.
- Apply cleaning solution – Follow the manufacturer’s instructions when it comes to diluting the cleaning solution. Cleaners can apply the solution using masonry cleaning brushes, chemical pumps, or sprayers.
- Rinse thoroughly with water – flush walls with a large amount of clean water. A thorough rinse is critical, no matter what method is used. The trial cleaning might show that higher pressure is needed. You should keep an eye on the runoff as you are rinsing.
