Sentinel Formula 626 Carpet and Sheet Vinyl Adhesive Remover, 5 Gallons

This adhesive remover after overnight application and covered with plastic drop cloth . Next day the glue comes off very easy. It won’t work after 1-2 hours leave it overnight. Please follow instructions to get the job done easy.

This product did not remove the carpet glue from my basement floor AT ALL. Called customer service and was told it only removes certain types of glue, which it does not say in the description. Also, they advertise for return, refund or replacement, but they do not honor this once the product is open! Absolute waste of time and money. VERY DISAPPOINTED. DO NOT WASTE YOUR MONEY!!

I applied 626 generously according to the instructions with a heavy-duty deck brush, let it sit for 90 minutes, and the adhesive came up quite easily using a 4-inch floor scraper. The pictures show a room with the adhesive still on the floor compared to one cleaned with 626. There is a little bit of adhesive left around expansion joints, but not enough to be a problem. I used about 4 gallons on 550 sq ft. I used a 24” rubber floor squeegee to scrape up the liquified adhesive and then mopped with Simple Green. It took me and my son about 5 hours, including soak time. Would’ve taken twice as long or more — and a lot of back-breaking labor — without 626. Just be sure you are using it on the correct type of adhesive (mine was brown carpet adhesive).

For me it barely loosened the glue. I applied it according to the instructions. I watched a video that showed it worked like I was expecting and was hoping for. However, I ended up having to sand down the floor after using the adhesive remover and a scraper. So I spent the money on the Sentinel and then rented a sander. Disappointed.

We pulled up carpet in our sunroom expecting to find concrete and instead found this broken tile mosaic. There’s tons of glue left on the tile and grout with an uneven surface that didn’t allow for the normal scraping to remove the glue, but it is working. Our application requires that we put the remover down, cover with plastic for an hour or two then take a scrub brush and wire brush to it, followed by a through mopping, then repeating the entire process two more times. It is a lot of work but considering that glue was used as a leveler on most of the floor, we think it is working well.

Followed the instruction, it does not work at all, amazon shall discoutnue this product. So other buyer will not be scammed. Do not buy.

This worked well for my husband and I - we saw a video on youtube for removing the nasty glue from glue down carpet (barf) and just recently bought a house that had just that so...we decided to give this product a try. It's been glued down in there since 1979 and that glue was rock solid. I poured 626 on direct, not diluted, and let soak for about an hour. We then started scraping and, with some elbow grease, was able to get that nasty junk up! If you've got a larger space, I would suggest getting the 5gal because you really wanted to cover the glue. Anyways, it worked well and didn't have a repulsive smell. That's a win in my book!

Sentinel 626 is supposably for carpet and "vinyl" adhesive removal. I followed all the instructions precisely. I watched several videos to make sure that I understood and knew what to expect and what I was trying to accomplish. I calculated the square feet per gallon and made sure that I even used extra, as suggested in several videos, I was not skimpy with it at all. Throughout the one+ hour set time that was recommended I agitated the glue and paper backing with a short bristle course brush push broom to improve overall effectiveness and I also made sure that any high spots were getting covered repeatedly so as to stay saturated with the product throughout that time. This product simply does not work for vinyl adhesive removal as advertised... In my professional opinion, for my situation, this was a disgusting waste of money that would have been better spent renting a machine and blade specifically used for stripping vinyl adhesive from the start. $75 machine, $75 blade, for the day. $150 all together at Home Depot, which ultimately is what I ended up needing to do anyway "just saying" 😉
