Mastic Remover 500MR Blue Bear BEAN-e-doo - 5 Gallon

Product did reactivate 30 years black mastic approximately 90 percent over 20 hours of setting time after applying. Product did not release any noxious fumes and actually had a pleasant smell.It was easily applied with a pump sprayer for very accurate coverage.Grinding the concrete surface appears to be a better option in this situation.

Works great on black mastic but not so well on white mastic. I am using it to remove mastic from under vinyl tiles and will be purchasing more. Citrus smell so no fumes.

Worked well in one coat to remove black mastic. Had to use a second coat in a few stubborn spots. A+

Great product. Follow the i structions and the 50year old mastic comes right up. We even pushed it farther than instructed by pushing the used product onto the next days section of work(we were working on a 4000 Square foot room). It softened up all of it and made easy work of the next day by picking up the old then applying a quick thin coat and a quick mop.

Very easy to use

Outstanding response time and way less expensive than Amazon!!

This product worked exceptionally well to loosen black mastic. 5 gallons cleaned up about 130 ft.². I used it in two stages, the first to get the majority loosened and removed, and then a second time to clean the Remaining stubborn areas.

easy to use, great pricing for product.

Great product, Great service..

Follow the directions and it does a great job!

This is fantastic and very easy to use!!

Great product. Had stubborn mastic on our concrete basement floor, poured this down, spread it with a straw brush and let it sit overnight. Mastic came off easily with a floor squeegee. Must use the degreaser suggested to clean off the mastic remover, but this was a great way to get rid of the mastic without using a floor sander.

It does what it claims to do. Excellent mastic remover

WE had tile and Carpet glue on concrete floor for over 30 Yrs.( Before we bought the house). It definitely did NOT work like your videos showed. We had to scrap with ice scrapers and wire brushes , even after two coats. I will not purchase again.

Doesn’t work. Ever since the EPA banned the only stuff that works, dichloromethane, nothing has worked. Looks like we have to start grinding our warehouses when we change the office layout.

Removed black mastic.

For me, this stuff worked really well. I poured small amounts on the floor, spread it with a paint brush, cleaned it up with rags after the mastic dissolved, then applied and cleaned a second coat.

I did get the black, asbestos laden mastic off our concrete, but it took more than the application rates shown on the can or advised by the tech help. Once we removed the old tiles, there was a lot of mastic residue, and the concrete (put down in 1948) was not smooth finished, so it was embedded thoroughly. The mastic had no strong chemical odor, although we did use fans as a precautionary measure. I think it's a good product and would use it again, but hope to never again have to.

Great product easy to apply.

I thought it was a little expensive at first, but I saved a lot on labor. My sister, 69 years old and myself 67, stripped about 500 square feet of mastic. I purchased a 5 gallon pail and still have about 2 gallons left. I put it on with a 3/4” nap roller, let it set about 2 hours. Kathleen used a 10” “blue steel” drywall tool screwclamped to a broom handle and I went behind her with a hard bristle brush. We used a squeegee to corral the sludge and most of the liquid. It was very slippery. A small pressure washer cleaned up the little bit remaining on the surface and it went down the drain. It was still slippery as snot until I mixed maybe 1/4 gallon of the degreaser that they recommend and swung a mop around like a sailer on the deck of a ship. No longer afraid of falling, we admired our clean floor. I should mention that I first rented a floor scrubber with a course pad. I did not use any Blue Bear Bean-a-Doo. When I turned the scrubber on in the middle of the room, it grabbed the dry mastic and drug me to the side of the room and threw me up against the wall. After another 5 or 6 times being slammed against the wall, I gave up and returned the monster to the rental store. After I was finished, I didn’t think it was expensive and I still have some left.

This stuff WORKS! Used on black tile mastic applied on my concrete floor and the mastic just dissolved into a solution that could be cleaned up!

Great customer service. Will be shopping here more often. The product works great.

Excellent product excellent customer service

While this product is great for smooth level floors this was a nightmare for me. I am currently renovating a old 1950’s home and my concrete floor is rough and has low points which made using this product extremely difficult and the end result was a sticky tar pit that was only able to be fixed by renting a mastic removing tool from Home Depot tool rental which honestly I wish I just did initially instead of wasting over $500 on this product. If I had to do it again I wouldn’t purchase this product and instead would just rent the tool from Home Depot! This was a very frustrating experience that I wouldn’t wish on anyone!

The product was even more effective than I imagined. It allowed me to safely remove black mastic containing adbestos, and I especially liked the fact that it did not produce offensive or strong odors. I would recommend this product to anyone!

Wow this stuff is amazing . I had about a 800 sq ft of 40 plus year old black mastic to remove . This stuff did the trick in just 2 hrs this stuff liquified the mastic a squeeged it into a puddle and kitty littered and shoveled it into a garbage can . I applied a second coat just to get some tough spots and to make sure I got all of it . I then used the degreaser and washed the concrete and shopvacuumed it . I have since stained and Seles the concrete it looks amazing thanks to this product I saved hours of back breaking work and not having to get this black mastic into the air just in case it had asbestos. Great product

Excellent product and the company is great to deal with

In the world of solvents, this is a miracle product. Basically turns the old black mastic into a liquid. Easy to apply; pleasant odor with no noxious chemicals; does not evaporate, unlike other solvents. Apply with yard sprayer; let sit 3-4 hours; squeegee into pools; use a shop vac to remove. The degreaser that comes with it does an excellent job removing any residue. Unoclean had the best prices and shipped instantly.

Works extremely well. Once applied to the floor, its low volatility keeps mastic in liquid form almost indefinitely. That way, it can be easily vacuumed with a wet/dry vac and disposed of. Pleasant smell, no harmful fumes, leaves a great smell after the job.

The concrete only restriction on the mastic remover was not communicated at time of purchase. Thankfully, Unoclean provided a return shipping label at their cost. Much appreciated.

Great product. I had to remove carpet glue (1000 square ft) on concrete. worked great and the best part no over powering fumes to deal with
