Because of its advantages of wear resistance, pressure resistance, and easy cleaning, terrazzo flooring is widely used in various places, such as hospitals, schools, office buildings, etc. However, due to the service life, construction quality, environmental factors and other reasons, the terrazzo floor may appear hollowing, affecting the use effect and safety. This article will introduce the simple and easy-to-understand methods and techniques of terrazzo floor hollow drum repair to help you solve this problem easily.
First, the cause of hollow drums.
There are many reasons for the hollowing phenomenon of terrazzo floor, mainly including:
Construction problems: the ground base is not properly treated during construction, and the ground base is laid before it is dry, resulting in the surface layer being jacked up when the water in the base evaporatesOr in the construction process, the adhesive material laid on the terrazzo floor is uneven, resulting in inconsistent ground strength and easy to produce hollowing.
Material issues: Poor material quality of terrazzo flooring, such as improper aggregate selection or poor binder quality, can also lead to hollowing in the ground.
Environmental factors: During use, the ground is subjected to pressure, friction and other effects for a long time, or the environmental humidity changes greatly, which may cause the ground material to shrink or expand, resulting in hollowing.
Second, the hollow drum repair steps.
For the hollowing problem of terrazzo floor, the repair steps are as follows:
Positioning and marking: First, locate the hollow drum area and mark it. You can use a small hammer or other tool to hit the ground and tell if the drum is hollow by the sound. For areas with large hollow areas or concentrated locations, they can be repaired first.
Cutting Cleanup: Use a cutter to cut the hollow drum area into several small pieces for easy repair. When cutting, the depth should be controlled to avoid damage to the base layer. After cutting, clean the hollow drum area to ensure that the base layer is dry and flat.
Filling material: Choose the appropriate filling material according to the material and base layer of the terrazzo floor, such as resin material, etc. When filling, it should be filled in layers and ensure that the filling material is tightly integrated with the base layer.
Trowel calendering: After the initial setting of the filler material, use a trowel tool to smooth the surface, and then calender the surface to make the surface smooth and flat. When calendering, pay attention to uniform strength to avoid chromatic aberration.
