Anyone know anything about stripping sealer from concrete. Owner doesn't know what was used, but it is yellowed and splotchy, so I'm guessing some sort of polyurethane.
If you've done it, I'd like to know if this is a "no. never again" kind of job. Seems like a lot of tedious work. Scope of work is to strip existing sealer, clean and reseal. about 4000 sq. ft. of driveway.

I had good luck stripping many years of paint off a porch using paint stripper and the surface cleaner but I wouldn't go that route.
Mike with Eco-Wares has a product that might work. I have not tried Erase Clean yet but so far everything I've gotten from him does what it's supposed to do.

It's very time consuming and not worth the money. There is a gel I've used to strip off but it's highly volatile and you really need to let it sit 8-12 hrs before pressure washing.

Here are a few photos. The one photo (the guy's feet are in photo) has a section that he did himself using a product called SureKlean. It seemed to work but only works for 50-75 sq. ft per gallon!
Personally I would run from that. You could bust your hump for 2 or three days and still not deliver acceptable results.

I know a lot of guys who do garage floors won't touch a job unless grinding is involved.
It might be the fastest, least problematic especially if being recoated.
Just need a strong vacuuming even after blowing it out.

There can be money to be made doing this, but you have to make a committment to become an expert and chase that type of work. If you you don't want to focus on that business, stay away. It is expensive. That coverage you described is about right. Stuff gets all over when you pressurewash it off. We make more money doing other stuff.

Exactly Tim, one ill-timed splash, or errant splatter when rinsing and you could be looking at restating the front door or repainting some siding or replacing some landscaping.

I've used Ramboard and 4 mil plastic to protect siding etc when pressure washing especially with chemicals especially deck stripping or brightning. Put painters blue tape on siding then duct tape to that the plastic or board. Works real well

I saw Tom Vogel with ACR Products again this past weekend. I met him in February in Bethlehem, PA. I saw a product he had that I thought would work so I asked him about this post. He said getting sealer off is a nightmare. You just have no clue what it is. One product will remove one and not touch another, etc. After talking with him I am sticking with what Ray said! "Personally, I would run from that."

This will do it and fast.
