Non-toxic, biodegradable mastic and adhesive remover
Franmar Blue Bear 500MR Mastic Remover effectively removes difficult mastics from concrete subfloors. Unlike most adhesive removers which are full of solvents and harmful chemicals that are dangerous to inhale, 500MR is very low-odor and low VOC. It's specially formulated from 100% soybean oil and is completely biodegradable.
It's also easy to apply, remove and dispose of and requires no special equipment. It works fast in only a few hours. On really tough jobs, it's low evaporation rate allows it to work for up to 24 hours. Allow 500MR Mastic Remover to do the work; it will save you labor and money.
For easier cleanup, Franmar makes their own cleaner/degreaser that works very well called 700DG Degreaser (aka Emerge).
This popular product works very fast and very well. It softens old brittle mastic that's stubborn and difficult to remove. Chipping mastic off a concrete floor is no fun, but this product makes it easy and safe. We've received nothing but good comments about this product for the past 10 years.

Use On Material
Asbestos, Concrete, Latex, Mastics, Vinyl
Removes vinyl or latex asbestos mastics coating from concrete floors. Cleanup: squeegee-remove softened mastic and excess Bean-E-Doo. generally, black mastic will dissolve into a liquid the consistency of very old engine oil, and can be scraped into a puddle. fill the puddle with a commercial absorbent, and then shovel into receptacle. all other mastics tend-lift as more solid than liquid and can be scrapped into a pile that can be picked up with a shovel.
after picking up the dissolved/lifted mastic, there will still be a slippery, film residue remaining. in most cases, mopping the floor with franmar chemicals emerge will remove the residue. for best results for cleanup, after removing softened mastic, cover floor with a commercial absorbent, sweep up and then follow with a mop rinse using emerge. * testing surface for residues after floor has been mopped: apply water-various small spots on the substrate. if water turns cloudy white, indicates there is Bean-E-Doo mastic remover on the surface. remop using a degreaser is recommended. then retest. let surface dry before applying new mastic coating.
in all cases, care should be taken not-over saturate the floor by using too much water.
in extreme cases, and/or for especially difficult floors, scrape up softened mastic, then pick up filmy residue with steam vacuum. cover floor with a commercial absorbent, sweep up and then follow a mop rinse using emerge. let dry before applying new mastic coating.
* use of rotary cleaning machines for cleanup are not recommended unless an area has been tested first. "

Application Temperature Range
Warmer than 55°F
Pour BEAN-e-doo Mastic Remover undiluted directly on the concrete surface. Do not exceed the recommended coverage. Applying too much BEAN-e-doo does not increase removal time, but does contribute-impeding the complete removal of residue.
Where there are wide cracks or seals, fill with a commercial absorbent like diatomaceous clay (e.g. OilDry), saw dust, or synthetic absorbent, before pouring BEAN-e-doo on the surface.
Use a long handled brush or broom-ensure BEAN-e-doo covers all the mastic trowel ridges.
Allow BEAN-e-doo-dwell until mastic softens (generally 45-60 minutes for asbestos mastic. Dwell time for vinyl and acrylic mastics is longer, in some cases up-4 hours.)
