Cement milk remover, here is our suggestion. If you are looking for an effective cement milk remover, then among our specialist products, you will find BETOFF-BIO. This effective plant-based agent easily dissolves all lime deposits and cement milk.
Betoff-BIO. Cement milk and dried concrete remover
Cement milk remover. And here is a little more information about cement milk itself.
The layer of fine particles from aggregate and weak, unstable cement is known as cement milk. Moisture moves through the concrete due to excessive water mixing, leading to the transportation of these materials to higher levels. When concrete is overworked or excessively manipulated on the surface, improperly finished or subjected to work movement, the amount of cement and fine particles (cement milk layer) increases. In addition, insufficient surface hardening plays a role in the development of cement milk. Therefore, cement laitance can range from fine dust to several millimetres or more in thickness depending on the compositional conditions.

Causes of cement laitance in concrete:
- Excessive amount of water for mixing
- Excessive work or manipulation of the concrete surface
- Improper completion of the work stroke
- Improper curing protocol
Cement laitance remover. Techniques for removing cement laitance
To ensure that materials such as paint and varnish adhere well to the floor, cement laitance must be removed. Cement laitance can be removed in several ways, and the approach will depend on the intended use of the floor and the working conditions.
1. Shot blasting method
Shot blasting is considered a quick and effective method for removing cement laitance. It involves the rapid burning of abrasive materials on the concrete surface. Additionally, the shot blasting method can clean at least 1000 square meters in a single day. Since the flooring can be continued in other parts of the room during the shot blasting, the fact that it’s a dry procedure is advantageous. Finally, compared to other techniques such as mechanical planing, cutting, etc., it is considered to be much faster, quieter and cleaner.
2. Mechanical planning method
We use concrete planing, also known as mechanical planning, to remove thicker cement laitance. To achieve better removal of cement laitance, the machine has rows of rotating milling cutters with tungsten tips.
3. Planning technique
This method involves the use of pneumatic tools. Pneumatic tools vibrate against the concrete surface. The planing process is slow, noisy, dirty and dusty.
4. Grinding process
We use this technique for edges and smaller areas. Hand-held grinding equipment for precision, control, and safety can remove cement laitance.

5. Acid etching method
We use this technique for non-porous or slightly porous surfaces and extremely thin cement laitance. Acid attacks and breaks down the upper surface, a highly effective technique. Use it only after exhausting all other options. In our betolix.pl store, you can buy a liquid based on hydrochloric acid salts that quickly dissolves cement laitance. We call this liquid BETOFF (CONCENTRATE).

6. Abrasion technique
There are several methods for abrading concrete and removing cement laitance, including sandblasting or using abrasive sheets. However, their use is limited and typically not applicable to larger areas.
Cement laitance remover. Efflorescence vs. Cement Laitance
Both cement laitance and efflorescence are white, powdery substances, but they are entirely different.
Cement Laitance Removal Fluid. Cement Laitance in Concrete
When a concrete mix contains excessive amounts of water, laitance is formed. This refers to the accumulation of soluble salts on the surfaces of the concrete. By choosing materials free of hazardous salts and preventing water from entering the concrete, we can prevent or reduce this occurrence.
Regulating the amount of water in the concrete mix can also prevent it.
Shot blasting, mechanical planing, cutting, grinding, acid etching, and abrasive procedures are some of the removal techniques. Pressurised water, sandblasting, and acidic chemical cleaning are also parts of the removal process. The most effective method of removing laitance from our experience and that of our customers is to use BETOFF liquid.
