Oil based paint on concrete

I have a contractor friend that had a paint gun explode on him while doing a fence and it splattered the customer’s brushed concrete driveway.

He reached out to me asking if there’s a decent chance it can come up, he already tried using a hot water pressure washer and paint thinner. He said the small stuff came up but the larger puddles didn’t.

Brock- did he try acetone? I have had success removing oil based paints with it

He just said ‘paint thinner’ so probably not

Transparent, semi-tranparent, or solid stain? Water-based or oil? Do you know what the product was?

No sorry he just said its ‘oil based paint’ for a fence.

He should call the manufacturer.

I called the manufacturer of the stain I use and asked a bunch of questions including how to get it out of concrete. They said to use a certain type of oven cleaner. Had to be that brand though. (I have it written down on my Pw notes doc but don’t remember which brand.) They were super helpful.

Thanks guys, he took your advice and called CS, they tried the suggested chem but didn’t do much. We tried!
