Disadvantages of Epoxy Flooring

Short lifespan

This is one of the major disadvantages of epoxy flooring; it is not a floor on its own and needs to be installed over an already existing floor surface like concrete, wood, or steel. This makes epoxy flooring merely a coat of temporary flooring solution.

This doesn’t necessarily mean the floor won’t last a while in your space; it only means that constant wear and tear takes a significant toll on its lifespan.

Cracks and chips is another problem you will have to deal with, especially if you accidentally drop a heavy object on the floor; this means epoxy flooring is not the best choice of flooring for areas with high impact and traffic like your garage or storage areas.

These cracks may start small, but after a while, they become bigger and cause a large portion of the flooring layer to peel off the floor. This constant wearing out and easily damaged feature of epoxy flooring will require you to frequently install new coats, which is not really budget-friendly.

Strong Smell

When being installed, wet epoxy flooring has a strong ammonia smell, which can be quite offensive as well as toxic.

Application Process

Getting the existing flooring ready for an epoxy flooring installation can be quite tedious. It requires a lot of preparation, and The existing flooring has to be clean and also without any kind of oil or solvents before the epoxy covering can be applied.
