Spike 5" Diamond Cup Removing Disc Wheel for Paint, Epoxy, Glue, Mastic with RCD New Technology & Rubber Cushioned Body (Spike, 5", 7.1 oz Very Light)

This caught my eye because I’d been searching for something to remove old epoxy from concrete. Everything else I tried, including sanding discs, took far too long, or didn’t remove the epoxy well enough. This did the trick! It’s made of lightweight metal, so you know it won’t wear down. And the diamond nubs haven’t worn down either. It almost works too well - so you have to be very careful using it, or else you’ll deeply gouge the concrete. Overall, worth the money and a good product.

Works great but wore out quickly.

No effort at all took Epoxy right off the floor Excellent product and it lasts a long time stripped 800 ft.² with one disc

They do an epic job and worth every penny.

Used to remove leftover mastic on plywood subfloor after removing tile. Worked wonderfully!!!

Good

Total waste of money pictures where taken after a minute of the blade is completely gummed up with mastic. In the description clearly states mastic as one of this blades uses. Don't by it you'll be disappointed!!!

Works great for a 10' ×10' area

Worked really well for removing a mastic flexible coating. Life span was about what I expected, would buy again.
