Franmar Blue Bear 500MR Mastic Remover Tips
For nearly a decade, 500MR (Bean-e-doo®) Mastic Remover has been replacing older mastic removers, usually made from petroleum based chemistry. The older removers evaporate very quickly, resulting in often offensive odors, and significantly contribute to air pollution and global warming. Franmar Blue Bear 500MR Mastic Remover evaporates very slowly, has a very low, non-offensive odor, and does not contribute to global warming. 500MR Mastic Remover’s advancements in mastic removal techniques sometimes requires a different approach to cleaning up. These tips are designed to help people evaluate which techniques will work best for their project.

• Pour Franmar Blue Bear 500MR Mastic Remover undiluted directly on the concrete surface. Do not exceed the recommended coverage. Applying too much 500MR does not increase removal time, but does contribute to 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 Franmar Blue Bear 500MR on the surface.
• Use a long handled brush or broom to ensure 500MR covers all the mastic trowel ridges.
• Allow Franmar Blue Bear 500MR to dwell until mastic softens (generally 45 to 60 minutes for asbestos mastic. Dwell time for vinyl and acrylic mastics is longer, in some cases up to 4 hours.)

• Use a long handled scraper or squeegee to remove softened mastic and excess 500MR. 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 to 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. For best results for cleanup, after removing softened mastic, cover floor with a commercial absorbent, sweep up and then follow with a mop rinse. Testing surface for residues after floor has been mopped: Apply water to various small spots on the substrate. If water turns cloudy white, indicates there is 500MR Mastic Remover on the surface. Remop using a degreaser is recommended. Then retest. Let surface dry before applying new mastic or coating.
• In all cases, care should be taken not to 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 a degreaser. Let dry before applying new mastic or coating.

Use of rotary cleaning machines for cleanup are not recommended unless an area has been tested first.

Easy to apply and even easier to remove and dispose of (land-fill friendly). 100% biodegradable, non-toxic and non-caustic - makes negative air, or other special equipment unnecessary. Very economical. Low evaporative rate allows it to continue to work for up to 24 hours. Allowing it to do the work saves labor. LESS LABOR = MORE PROFIT! After extensive testing, a U.S. Postal Authority said, "BEAN-e-doo (Franmar Blue Bear 500MR) does the trick, with money savings of almost 300%."

Franmar Blue Bear 500MR Mastic Remover is not recommended for use on wood surfaces. Using 500MR might slightly darken a concrete surface.

Sentinel 626 Mastic Remover

Sentinel 626 Carpet Adhesive Remover 626

Sentinel 626 is a mastic remover with a powerful biodegradable formulation designed specifically for quickly removing latex, acrylic and pressure sensitive adhesives from concrete, terrazzo, ceramic and vinyl tile or wood substrates. Sentinel 626 is odorless, nonflammable, and biodegradable.


Removal of latex, acrylic and pressure sensitive adhesives:
Step One: Apply 626™ directly onto the adhesive. Use a broom, mop or squeegee to agitate and maintain even coverage while keeping the adhesive surface wet. Allow 626™ to soak and penetrate for 30-60 minutes.
Step Two: Scrape softened adhesive from the floor (razor scrapers or squeegees are generally preferred). Repeat steps one and two if necessary and dispose of the waste.
Step Three: Rinse the sub-floor thoroughly the clean water. Allow surface to dry.

Removal of sheet vinyl/linoleum backing: Once the wear layer is removed, mix 1 part HOT water to 4 parts 626™ ( 1 quart of HOT water to 1 gallon of 626™ ) and apply directly to the remaining backing. Maintain even coverage and a wet surface for 1-2 hours or until backing and adhesive can be easily removed together with floor scrapers. Rinse the surface with clean water, and allow to dry.

Removal of carpeting: Using a utility knife, cut the carpeting in 1-foot strips (making sure to cut through the carpeting to the sub-floor). Mix 1 part HOT water to 1 part 626™ ( 1 gallon HOT water to 1 gallon 626™ ) and pour directly onto carpet to be removed. Maintain even coverage and completely saturate carpeting with 626™. Allow to soak 4 hours or overnight. Pick up carpet strips and follow latex removal procedures.

Coverage for the mastic remover will range from 25-75 square feet per gallon.
