Looking for a stripper :-)

[japsfinest]

I thought l that would get your attention!

So it looks like there is about 10 years worth of shop grease and oil spills that have seeped into the concrete slab. I have been pressure washing for about 16 hours and only gotten through about 1/4 of the slab. I think it's time for a chemical intervention hence the stripper..can someone make some recommendations on a product that will help loosen up the grime and lift or eat the grease and oils that are on the Surface.

I am prepping for epoxy and know for any product to last it's all in the prep. This prep is is kicking my ***. All suggestions welcome.... thanks in advanced!

When I cleaned the garage at the rental. I mixed up TSP in a thin paste and brushed it on the drip area in the middle where the car would have parked. A couple of applications and most of its came off. There are lots of commercial products to loosen up these stubborn stains, although you may never get it completely clean again without mechanical action.

We use a floor scrubber at work. With three of us we can get the whole eight bay shop fully scrubbed in 2-3 hours. This includes sweeping and picking up. And squeegeeing off the excess rinse water. We use the heavy duty black pads and some powdered commercial floor soap. These things are rentable at many rental places. It makes the floor go from black to almost clean concrete.

I have come to the conclusion that I need 2 things: 1-stronger pressure washer rated at a higher PSI, and 2-some type of mechanical agitation with chemical.

I have been using 1800psi with only water and no agitation. I am going to rent a scrubber to assist...

Thanks for the input

Hi,
Not sure what type of epoxy you plan on using but in our experience oil/grease can never be 100% removed from a slap, hence why we carry Oil Stop Barrier Primer. This is a special primer designed to adhere to concrete with residual petroleum products entrained in the slab.
