I've been putting water paint on my garage floor because I'm allergic to oil paint and I'm having a hard time getting it to stand up especially with a boxer dog. I know there are different things to put on instead of paint but sometimes I get a leak under my door and I'm not sure about water getting in under something else. I use my garage as a walk in most of the time and I also use it for my laundry room. I hear the G-FLOOR is good but like I said what would I do if water happened to get under it? My garage door is sealed from the outside. Any suggestions anyone?

You can use garage floor apoxy.
This stuff is suppose to protect the floor from everything; oils, water, grease, etc.

What is apoxy? I've never heard of it. Is it strong in smell? Is it a color because I have to cover the grey paint that's now on the floor. Does it take long to dry? I know I'm all questions but I really have to know what I'll be using. Have you used this yourself? Thanks!
