Safe on our 60 year old marble!
Needed something that would remove peel & stick tiles without discoloring/damaging the marble floor underneath. Peeled up tiles, let this soak 15 minutes, and used a scrapper to remove glue. No damage to my 60 year old marble!

    Poor Product Does Not Work as Described
    This product does not work on glue down flooring. Applied product as directed and it just sat on top of the glue even after 24 hours. Total waste of money, returning to home depot. Don't waste your time with this product, hot water works better! Picture attached with remover still sitting on Top of Glue.
      Removed some adhesive
      Applied the solution as directed on the container, even tried leaving the solution on the floor with plastic covering and leaving it overnight, still did not soften the adhesive. It softened a different type of adhesive but was a real pain to clean up. Odor was strong even with sliding open. I have the fan ventilating the room for 2 days yet the strong odor is still persistent. I was hoping that Home Depot would let me exchange this with a different adhesive remover.
        Does this work - YES !!! My only con - it does take muscle. Be prepared. The clean - up is messy...
        Does this work - YES !!! My only con - it does take muscle. Be prepared. The clean - up is messy, I mopped till clear. The floor was still slippery so I let dry, then sprinkled on baking soda. I left overnight and swept in am. Wow - a huge difference.

          Only Partially Effective
          I am removing a brown adhesive from a porch that previously had outdoor carpet on it. There are also spots of black mastic from an even older job. Formula 747 is taking off about 50%-60% of the brown adhesive, but it takes a fair amount of scraping. It gets only about 10% of the black mastic off. My porch has a slight slope (so would a deck, I imagine) and the Formula 747 flows off, making it difficult to leave it on for the required working time. Don't let it splash on your skin, it is irritating. Wear goggles. My porch is about 7' x 11' and I've used most of the gallon. Have not made a lot of progress.

            Amazing product- A life saver!!!!
            I was in the process of refurbishing a 20 yr. old fishing boat and had gummed up, old contact cement all inside the hull. It was the consistency of gummy bears and a power scraper or sander or angle grinder could not tackle it without gumming up the discs. I tried all kinds of solvents suggested by other boaters: laquer thinner, acetone, Mek, Xylene, mineral spirits and even oven cleaner, all with minimal or very limited success. 3M adhesive remover might have worked but was prohibitively expensive for the amount I would have needed to do a 17ft. boat. I thought I was doomed to spend the rest of my days in my life scraping the gummy stuff off an inch at a time with tremendous elbow grease. Then saw the Sentinel 747 product on the shelf at HD, and even though it had many negative reviews, I decided to give it a shot. OMG-what an amazing product: I sprayed it on (on vertical surfaces now mind you). Waited 45 minutes and the glue was like warm butter and scraped right off with a putty knife. Removing the glue was now a breeze. In a few spots the glue was very thick and I had to respray over again with the same amazing results. Thank You Sentinel 747, you have a wonderful product that really works and I did not have to wear a respirator and worry about a flash fire using dangerous and ineffective solvents! I don't understand all the negative reviews but if you are dealing with contact cement-Sentinel 747 is the Bomb!!!

              747 Plus works! I used it to remove wood floor adhesive (which was laid on plywood floor decking). I soaked paper towels in 747 Plus and laid them on the adhesive - I did this around 9pm. In the morning (7am), I removed the paper towels and used a 2 inch width chisel and scrapped the glue off with ease.

                I am not sure if this is doing anything more then just soaking in water would do. Makes a goopy mess with lots of fumes and still requiring LOTS of elbo grease. I will finish the bottle and go back to just water.

                Massive Mastic Mess and the magic Remover that worked great!
                We had a massive amount of the old cutback/mastic adhesive to remove from our concrete slab floor throughout the living room dining room and hallway.. used to glue down old wood floors 50plus years ago and it was thick everywhere. This remover we poured it on used a metal scrub brush to to rough it up and let it sit for 2 to 6 to 12 hours depending on just how thick it was and how tired we were of scrapping and scrubbing and it was like magic it removed everything a little effort was put out but not nearly what we were doing with other removers. Its a bit messy we had that black tar slurry in lakes and puddles and it was so thick in places I never thought we would get rid of it but a little cat sand or other type of absorbent clay/sand poured on the slurry then stirred until it was not a liquid anymore...all we had to do after that was scooping and dumping! we were finished in no time. It works and it works great it was not instant for us but I believe had an unusually large amount of that stuff on our floors. Hate Cut Back LOVE LOVE this remover! OH and no real odor to the product or at least not one we could smell over the old mastic smell ick!

                Removes Black Mastic (old adhesive)
                This was for 100 sqft room I poured the product on, directly to the surface. Staying within a 2x2 area. I waited 20 mins, used my scraper to take off the bulk of the adhesive, collecting it with paper towels (Bounty 8 rolls). In the same 2x2 area, I used the 747 Sentinel in an old Windex bottle and gave a light coat. Then used an old dish brush to work the product into the concrete. Using paper towels to wipe it off. Afterwards, when this black tar mess was wiped up. I went over the concrete with driveway/concrete cleaner and a hand brush. Advice: Use paper towels to collect the mess. Dont wear clothing that you care about. Kitchen gloves are your friends. Its not toxic, just messy.
