I have been thinking about covering my garage floor with epoxy paint made for garage flooring. Here's my question, I have spilled every kind of oil on the concrete slab and have had paint spill on the slab. I have cleaned the spills up of course but residue of the spills still remain.
How clean do you have to have the concrete to apply the floor coverings.
So lets look at this practically. When I was a kid growing up we had an old garage door that had lead based paint on it. It was flaking and a total disaster. If we repainted that door, without the proper prep, no one would think that it would hold up.
The same is true of a garage floor. Oil, especially causes major issues with epoxy. Then a year later, if that, people write in about how their epoxy 'failed' from hot tires when in reality it was just not properly applied.
I would start with some Pour N Restore. Why, not because I sell it, trust me, its not a high profit item... IT WORKS. Use it first and **** any oil that's in the floor out. You may need to repeat. Then use a degreaser or detergent and clean up the residual on the floor.
You will need to acid etch you floor or preferably grind it. This is not for cleaning but to profile the floor.
If all of this sounds like a lot of work, it is! BUT a beautiful epoxy floor is well worth it. If you would prefer not to do the work, products like our garage floor tiles and garage floor mats are designed to go directly over your existing issues and give you a beautiful floor.
