How is the bonding strength between gypsum self-leveling and the base layer?
Publish Time: 2025-02-11
As an efficient and environmentally friendly floor leveling material, gypsum self-leveling is widely used in various building decoration projects. Its unique self-leveling characteristics make construction easier and faster, and its bonding strength with the base layer is one of the key indicators to measure its construction quality and service life.
The bonding strength between gypsum self-leveling and the base layer mainly depends on multiple factors, including the material of the base layer, the treatment process, the material quality of gypsum self-leveling, and the technical control during the construction process. First of all, the material and treatment process of the base layer have a vital influence on the bonding strength. The base layer should be firm, without hollows and oil stains, and the surface should be flat and clean, without shelling or peeling. Before construction, the base layer should be fully cleaned and treated, such as removing surface impurities and polishing to ensure that the gypsum self-leveling can be tightly bonded to the base layer.
The material quality of gypsum self-leveling is also an important factor affecting the bonding strength. High-quality gypsum self-leveling materials should have good fluidity and adhesion, and be able to form a firm bonding layer with the base layer. During the construction process, the proportion and operation should be carried out strictly in accordance with the product instructions to avoid problems such as excessive water addition or uneven mixing to ensure that the performance of gypsum self-leveling is fully utilized.
In addition to the base treatment and material quality, the technical control during the construction process also has an important impact on the bonding strength. During the construction process, attention should be paid to controlling the thickness and uniformity of the gypsum self-leveling to avoid problems such as uneven thickness or hollowing. At the same time, before the gypsum self-leveling initially sets, proper vibration and smearing should be carried out to eliminate bubbles and enhance bonding.
After the gypsum self-leveling construction is completed, it should be fully maintained and dried to ensure that it achieves the best bonding strength and performance. During the maintenance period, heavy objects should be avoided from pressing and trampling to avoid affecting the bonding effect and the flatness of the ground.
In summary, the bonding strength between gypsum self-leveling and the base is one of the important indicators to measure its construction quality and service life. By strictly controlling multiple links such as base treatment, material quality, construction technology and maintenance process, it can be ensured that the gypsum self-leveling forms a solid bonding layer with the base, providing high-quality ground leveling solutions for building decoration projects.
