An epoxy floor can be walked on 24 hours after the floor is finished. Always test the floor by feeling a small area, if the floor is still tacky, continue to wait and check back every 6 hours. You should wait 48 hours before using heavy equipment or vehicles on the surface. With a polished floor, as soon as the floor is finished it is ready to use. The final step seals the concrete and makes it ready to use right away. We do recommend that you protect the finished floor if you are having other construction work done, as the floor is susiplte to scratches and staining.
