How to deal with the problem of blistering in Zhongshan Epoxy Floor

Zhongshan Epoxy Floor coating has certain requirements for the construction base surface. Therefore, the base surface must be inspected carefully before construction. If there is a problem with the base surface, the base surface needs to be repaired and processed to construct the Zhongshan Epoxy Floor.

1. The unevenness of the base surface: Use the method of water-abrasive grinding to smooth the protruding parts to a flat surface (if the base surface flatness is too bad, beyond the range that can be polished to solve, it is recommended to construct a new cement screed and then construct the epoxy floor in Zhongshan. Coating), remove laitance and allow it to dry naturally. This method can only be used in projects where the construction period is relatively abundant. If the construction period is tight, it is not suitable for use.

2. There is a crack on the base surface: The crack is cut into a V-shaped groove with a cutting machine, the groove is cleaned, and the V-shaped groove is filled with epoxy mortar (solventless epoxy floor paint plus quartz sand).

3, base surface sparse from the shell: use a small hammer to beat the base surface, the base emptying, loose, from the shell and other ground, as far as possible to eradicate, and remove and carefully clean up the surface layer of contaminated construction adhesives and coatings, etc. Clean the floor and remove the uneven ground to repair.

4. Shot Blasting: All shot blasting is performed on the base surface to remove surface loose layers and the corners are treated with a dry sander.

5. Base surface cleaning treatment: Clean up all the garbage on the treated base surface, and then use industry vacuum cleaners to clean the dust. It is necessary to seal the construction site before use, and prevent the quality of the cross construction project from causing damage.

With the development of society, there are many places in Zhongshan Epoxy Floor, but with the day and night and the season's atmospheric temperature is constantly changing, or gradually increase, or gradually reduce. Epoxy coating after the application of Zhongshan Epoxy is very easy to blistering phenomenon, the development of the speed is also very fast, different shapes of bubbles, different sizes. The observed blisters have no direct relationship with the construction site. Some blisters in the same construction segment did not blistering. It can be seen that blistering is caused by many factors. We have already mentioned the reasons for the blistering of Zhongshan Epoxy floor.

1. Avoid exposure to sunlight after the epoxy has been applied and reduce the temperature difference between the epoxy layer surface and inside.

2. In the epoxy layer construction, the primer layer should be made of good quality material: let a part of the epoxy penetrate into the base layer or the waterproof layer to form an integral whole; enhance the adhesive force, and leave little residual or chemical gas after curing. .

3. To improve the adhesion of the epoxy layer and the base layer or the waterproof layer, to overcome the expansion force of the initial blisters to avoid the occurrence of blisters. Waterproof layer on the grass-roots level to prevent water uptake control base or water within the waterproof layer within 8%, the base or waterproof layer compressive strength greater than 20MPa, epoxy construction.
