How do I seal my garage floor?

Use a penetrating sealer and apply it using a paint roller or a pump spray unit. It needs to be able to dry well. Here is some information regarding penetrating sealers: Penetrating sealers penetrate deep into the concrete pores and form a gel. This gel expands filling the pores and hairline cracks in the concrete, turning the concrete into a solid mass. This process will not let water on the surface soak into the concrete, keeping all the harmful contaminants on top and easy to clean off. It will also keep moisture and vapor from migrating up through the concrete from the subgrade below.

It drys very quickly and is invisible, this sealer will not change the look of the concrete, you won't even be able to tell it's there until something is spilled on it. This garage sealer will not make the concrete slippery, it doesn't leave any type of film on the surface.

Look for one that says penetrating water based silicate sealer.
