## Description

Will This Remove My Type of Mastic or Flooring Adhesive?
Type 1 mastics are water-resistant and may require longer dwell times. Type 2 mastics are commonly found on concrete floors and typically remove more easily. Black mastics also soften well but often create a messier cleanup process.
How Does Adhesive Thickness Affect Removal Time?
Thin layers usually soften and liquefy quickly. Thick applications, especially over 1/8 inch, may require several hours of dwell time. Keep the product wet while it works to ensure maximum effectiveness.
How Long Should I Let the Product Work?
Allow at least 1 hour of dwell time for best results. Black mastics often soften within 1 to 2 hours, while vinyl and acrylic mastics may take 4 to 8 hours. Stubborn adhesives can require longer dwell times.
What Conditions Deliver the Best Results?
Best results on clean, dry concrete at 55°F–85°F. Let sit at least 1 hour and keep wet while working. Thin mastic removes faster; thicker or older adhesive may need longer dwell time to fully soften and release.
What's the Best Way to Clean Up After Removal?
For black mastics, apply an absorbent material such as oil-dry before collecting the residue. Lighter mastics can typically be scooped into a disposal container. Always clean the surface thoroughly before installing new flooring.

### ⭐⭐⭐⭐⭐ Works on the oldest mastics
*by  on Reviewed in the United States June 6, 2026*

This product worked great on complete removal of 80 year old mastic. Now, it doesn't just eat mastic instantly, it takes a bit of working. You need a floor scrubber with hard bristles. It takes about a half hour for the compound to start affecting the mastic. Should be scrubbable at that point. After a good scrub you should get a clean squeegee wipe and the compound will be dark like used motor oil. The compound will keep the mastic from sticking to the bristles as well. Squeegee into some absorbent so you can sweep it into a bag. Don't just dump a bunch on and let it sit. It will evaporate and the mastic will become gummy. Just hit a corner, scrub, squeegee, and then reapply if you need more. You can make the product stretch more that way.The odor is no big deal. Citrusy, but definitely has an underlying "Cooking oil" smell. It actually works better than paint thinner and yes, I tried that on a small spot. Value? Well, the stuff isn't cheap, but I have tried the cheap stuff and it doesn't work. This stuff will work no matter how old the mastic is so you can't get much better value than that. It is oil so you will need a good supply of Dawn soap or a suitable degreaser to mop the floor clean with. You can probably push some absorbent around to wick up what you can as well. You have to get all that oil out if you plan on redoing the surface.

### ⭐⭐⭐⭐⭐ Works great! Buy enough to liquify the mastic!
*by  on Reviewed in the United States April 27, 2016*

I have a 1000 square foot basement that had old vinyl tile on it. After the tile was removed, I had of course discovered the black mastic that will lead most people to this product. I watched several videos, read the reviews, and did my research on different methods of application and removal.Ultimately, I ended up needing two five gallon pails to fully liquify the mastic. The first pail liquified certain spots where I had put it on thick, but others were just tacky. With ten gallons of Bean-e-doo I was able to successfully liquify the mastic. The mastic turns into a black oil substance and was wasy to soak up and remove.My procedure for application and use was as follows. Using a small broom, I applied a liberal coat of bean-e-doo across the floor. I let the bean-e-doo sit for three hours and then went down stairs with a steel bristle deck brush on a handle. I squeeged the liquid around the floor until I located a spot that was still hard. I would then squeegee the liquid oil like substance into this spot and scrub it with my metal brush until it was bare concrete. After I had scrubbed all of the hard spots and successfully removed most of the mastic, I squeeged the mastic oil into a centralized location and covered it with four bags of kitty litter. I shoveled the saturated kitty litter into the empty beanie-e-doo pails and an additional bucket I had laying around. I sealed all three of these and took them to a disposal center.I used a mixture of one gallon dish soap and two gallons of simple green to degrease the floor temporarily while I prep part of the floor for demo and a bathroom installation. I again used the steel brush and scrubbed the floor as I went. This was followed by pressure washing the floor and then I squeeged it dry.Upon completion I intend to use the emerge degreaser that I purchased to remove any residual product left behind.On a side note, it did leave the basement smelling pretty bad, but with the new egress window I am cutting out it should ventilate well.

### ⭐⭐⭐⭐⭐ Easy with a rented floor buffer machine
*by  on Reviewed in the United States January 2, 2023*

I needed to remove about 700 square feet of black mastic from 1967. First, tried two other products that weren't able to soften my mastic. I switched to the Blue Bear and it did the trick.I did my job by applying the wettest coat of Blue Bear that I could. I used 10 gallons for my 700 square feet of floor. I allowed it to sit overnight. In the morning, the floor was still wet in areas, but in other areas the mastic had absorbed the Blue Bear liquid.Next, I went over the whole floor with a rubber squeegee and collected all of the now liquified mastic in a bucket. After the squeegee work, a lot of thick mastic still remained, but it had been softened.I then rented a 17 inch floor buffer and bought 20 of the 3M black floor stripper pads. I also bought 7 gallons of Zep citrus degreaser concentrate to wet the floor and help with the cleanup. From there it was almost easy! I poured the degreaser concentrate right on the floor and used the machine to wet scrub the mastic. This method would remove about 4 square feet of mastic every 15 seconds. All of the liquid and mastic wound up soaked into the stripper pads. Once a pad filled up with sludge it would need to be changed. I easily used all 20 of my pads and wished that I had bought 5 more. I finished the main job in about an hour and then cleaned up the corners by hand with a steel wire brush.Finally, after two rounds of mopping with detergent, my floor was clean and ready to tile.
