I had my shop floor poured with concrete a few weeks ago. What is a reasonably priced but effective protective floor covering that I could use against oil and grease. My shop floor is just under 600 sq. ft.

 

If doing it yourself I have heard good things about Rustoleums epoxy floor coating. Just make sure you prep it properly even though it is new concrete.

 

Neighbor just built new home and applied coat of sealant on his new garage floor. He's the type of person who thoroughly researches a product and compares to other simular products before deciding whether or not to purchase, drives his wife up the wall, no impulsive purchases in that household. They appied it themselves and from the pic's it looks good. Understand the warranty may be better than some of the others. Anyhow, posting link, may want to take a gander. Believe Lowes, and or, Home Depot have simular products.

I've heard negitive things about the Homedepot stuff, but never tried it. I've heard good things about U-Coat-It. I don't know the price difference, but it's not as cheap as the HD stuff.
Might be worth a look.
