didn't see that stuff was made out of PP

acetone. steal wife's nail polish remover and hope it's not the non-acetone kind.

or better yet, install a hardwood floor upside down on top of the brick and then peel it up in a few months. that **** sticks to hardwood too.

 

The pad was most likely polyurethane, you can normally cut it with lacquer thinner. The muriatic acid I recommended to try might be a little too strong to use indoors.

 

I poked around a bit and all signs for me pointed that the stuff was made from PP. Polyurethane will be significantly easier to get rid of with chemicals.

 

I will have to double-check when I get home, but this stuff looks like what I have. It says PVC-coated polyester. I'm going to locate a receipt or ask the wife to narrow it all down, but I'm pretty sure this is the stuff.

Now what?
Mohawk Non-Slip Rug Pad

 

If it is PVC then you want acetone or MEK to break it up. Or PVC cement, but that is kind of too thick to clean with.

 

Yup, checked some receipts... here it is, definitely PVC:

Actual pic of same thing on my hardwood floors.

No luck with pure acetone... let sit for about 5 minutes and then scrubbed the **** out of it... it just laughed at me.

 

I was in a very similar situation and was able to use oven cleaner form the $1 store. i'd poor it on and let it sit for a few minutes then take a brush to it. almost like i was cleaning my driveway on an accidental oil spill lol. It took me a couple weeks. I did it twice a day for 10 days. it was a good day when i didn't have to scrub that **** anymore. I will never again put that non slip junk on my floor.

 

MEK doesn't work in this case, that and the smell, my god D:

 

Pressure washer, or a scrub brush made from Hustler's pubes.

 

Best advice yet... and will be buying a bottle of oven cleaner tomorrow.

 

PS: Thanks for all the suggestions here... I'll drop an awesome picture for everybody's efforts.

 

do they do that when they need to move the carriers faster?

have you considered pointing the business end of that thing at the floor??

 

Dur, why didnt we think of this before. Just burn the **** out of it, just keep the room well ventilated because PVC make arsenic and choline gas when it burns. Hmmm making rat poison and WWI chemical weapons in your house all of a sudden sounds like a bad idea.

 

plus didn't he say the brick was sealed with something?

 

It has been sealed with a standard masonry sealer of some sort... just the brush-on kind out of a can. It's possible the PVC over time had a chemical reaction to something in the sealant and they're bonded.

I'm sure there are lots of options to get this stuff off... but they all involve vacating the house for a couple days. We may end up setting up a big paint-type spray booth and getting a pressure-washer. The mess will be epic. It's going to suck.

Additional awesomeness:

 

Here's what I'd do:

Leave it. Move out.

 

Have you tried heating it up with a good hair dryer or heat gun??
