How long is the waiting time between each sealing application?

When applied with a synthetic mop head in a thin layer, the dry time for our Rubber Floor Finish and Sealer is 20 - 30 minutes. This is the amount of time you will want to take between layers. If you are uncertain if the product is dry, take a finger and see if it is tacky at all. If it is, take a fan and run it over the surface to help the sealer dry.
