Epoxy resin flooring is usually applied to the concrete expansion joints in the following ways, each with its own advantages and disadvantages: in the coating of the floor, epoxy resin mortar (which should be solvent-free) rigid material The expansion joint is filled, and then the whole coating process of the floor is carried out. Before the cracking occurs after the coating is completed, the expansion joint is not visible on the floor coating.
Epoxy flooring does not ensure that the floor coating at or near the expansion joint does not crack and shell. Because such steel materials are not elastic and cannot withstand the stress when the concrete shrinks and cracks, cracking cannot be avoided.

This kind of treatment method is often used in electronics factories, pharmaceutical factories, and precision instrument manufacturers where high cleanliness and aesthetics are required. It can basically avoid the cracking of the floor coating at the expansion joint, and it is also beautiful. The disadvantage is due to the current polyurethane. The elastic color is relatively small (generally grass green and iron red), which is not easy to reach the color of the overall floor coating. At the same time, with the thermal expansion and contraction of the concrete, the polyurethane elastic rubber will also have protrusions and depressions. .
