Benefits Of Epoxy Floors

Epoxy floors are well-known for their longevity and resistance to dirt and scratches. For a basement floor, they provide the following advantages:


Mold and mildew often breed in basements due to the levels of humidity in the space. The growth of these harmful bacteria comes from moisture. Thus, protection from moisture is essential to keep a basement fresh.

Epoxy floors are usually waterproof, which helps protect the basement from moisture buildup and leakages or spills. In connection to this, it is resistant to bacteria and eliminates the possible spread of mold and mildew.

To be sure, test if your painted floor is compatible with epoxy by taping a plastic sheeting on the floor and sealing it, then leave it for about 24 hours. Then remove the sheet and check if there is moisture on the underside. If it is dry, it means epoxy will bond well with your floor.

However, if the floor paint shows extreme signs of wear and damage, you will have to prepare the surface before applying epoxy to avoid further harm. In this case, you need to remove the paint and sand down the surface as much as necessary.
