Same here, I've been putting off doing the garage until landscaping done. Now my garage is next. Except, I already collected full of junks within two years time. I guess it, bound to happen.
There is a company in Anaheim that manufacture only epoxy for garage and this what the professional use. I forget the name, but the kits is not cheap like lowes or homedepot. I think the cost of 6 hundreds or more for just material for two car garage. Then, I can either DIY it or just hire a guy to do the work. Can't remember the name of this product.
