I was trying to remove glue from concrete that was used for carpeting. I want to put down procelain tile but I needed to remove the glue before doing so. At first I tried using just a high quality scraper to scrape the glue from the floor. After trying this I realized it would take days to finish, the glue seemed impossible to get off the floor. I purchased this adhesive remover to make the job easier. If you follow the instructions it works wonderfully. Using the plastic sheating and using a paint roller to distribute the remover is required. Wearing safety goggles and gloves is necessary. If you get this in your skin it will burn immediately. This seems like it covers quite a lot of square footage.

Rated 5.0 out of 5.0 by CMD Works Great-Follow Directions-See Comments for a Tip
Project-Removing thick carpet mastic on concrete floor (8-10 years old)
Process-Lay it on the mastic thicker than you think you should
Time-Sweet spot is approx 30 minutes (temp of floor may require longer)
Scrape-Use large blade, long handle scrapper to remove lots of material
Area-work in smallish (ie the length of your arm) sections that you can remove in 30 minutes
Tip- There will be remaining mastic that did not come off easily. Put second thick application on those areas and use a stainless steel scouring pad (and thick rubber gloves). Use the scouring pad to remove all the remaining residue. You can add some HOT HOT water as you scrub (after the 30 minute cure time) to help lubricate the scouring pad and to drive some of the remover around to further remove mastic. Rinse pad often, use rags or shop vac to suck up watery glue off floor.
Final Step- rinse floor with clean water, let dry.
Bottom Line- This is one of the worst jobs to tackle (homeowner or professional). You can rent big machines that make a huge mess ($700 per week rental), you can pay big bucks for eco friendly products.....at the end of the day, you will need to do 2-3 applications depending on how clean you want floor and scrub the floor on your hands and knees to get it all off. If you plan to stain concrete, you may need to to really spend alot of time scrubbing off mastic. We will be installing Karndean loose lay flooring and we did 2 applications and scrubbed entire floor with steel wool scrubber. Be patient, let the product do its job and find the Time to Cure "Sweetspot". Good luck and make sure you have a cold six pack on ice and ready to go. That first beer will never taste sweeter!

Rated 1.0 out of 5.0 by Valera Horrible experience
We wanted to try this product instead of renting a machine to get the glue off the concrete, thinking we could avoid a big mess. Big mistake. It made a huge mess, now the floor is wet and we will have to wait for it to dry before we can start working again. While it took some glue off, it mostly didn't work. We followed the instructions carefully, but using plastic cover did not make a difference. It seems to work okay if you want to get some adhesive off, but it smears horribly and will really not get your concrete clean the way that a concrete chipper/grinder will. The amount of work and adhesive it would take to actually clear the floor places it well within the realm of not worth it.

Rated 5.0 out of 5.0 by Phil This adhesive remover is AMAZING
This adhesive remover certainly did the job! I scraped the tile adhesive without this the night before and it took 2 hours to do a little area. With this product, I did my entire dining room in less than an hour. I did not use plastic, I simply dumped the product right on to the adhesive areas. From there, I used a paint roller and spread the product out evenly. I let it sit for 15-17 minutes and the used a floor scrapper. The adhesive peeled right off the floor.... easily. The fumes are strong so be sure to open windows, have fans on too. Also use gloves, it irritates skin.

This is the only product I've found that will readily remove carpet mastic. I used this on a 300 sq ft concrete porch that was carpeted and needed removed.
However, there are some things that need to be closely followed according to the directions and my experience..
First, when working outside, be sure to use plastic film to cover the application as instructed. This remover dries quickly and the mastic will begin to harden again as the remover dries out.
Second, the outside temperature will affect the drying time. I found that daytime temperatures of 70-80 degrees causes the remover to dry too quickly before soaking into the mastic and it wouldn't come off down to the concrete.. So, I decided to apply the remover between 7:00- 9:00 o'clock in the morning before the sun comes up. This slowed the drying time and brought up more of the mastic down to the concrete.
Third, work in small sections. The directions say 9 sq. ft. at a time and that is about right. Remember, once you remove the plastic film and start to scrap the mastic off, the remover will begin to dry faster. Trying to cover a large area is going to allow the mastic to set up again before you get it all.
Fourth, the directions say to leave the remover on for 15-30 minutes but don't wait 30 min. After 15 min., pull back the edge of the film and check with your scraper. I can't emphasize enough how quick this stuff will dry due to temperature regardless of the plastic covering.
Don't get me wrong as to this being a simple operation. I'm going to have to go over the porch again to get all the mastic off because i learned these things too late. But if you follow these suggestions, you'll find it works pretty well.

We are cleaning carpet adhesive on top of vct adhesive from a concrete floor. The floor is about 20 years old. We are using a paint roller to put down klean - strip in small areas of about 2 by 8 feet and not using any plastic to cover the areas. We are waiting about 15 minutes and using hand scrapers with 4 inch razor blades to remove the adhesive. It comes right up in about 95% of the floor. In our case some areas with a heavier vct layer get a second coating. Fumes are a little irritating so using a fan to vent area. Still requires some elbow work, but makes it a much easier job. Recommend it.

Rated 5.0 out of 5.0 by Nick best I've found
This is the best I have found for removing floor adhesive. It is very messy if you are not methodical. I tried plastic cover and found it more of a hassle than a help. You must do a small area at a time so the stuff doesn't dry out, then its worthless. A tip, remove one row of tile, then use Klean Strip to clean up that one row. Then go to the next. This way you will not track glue all over the place and have to go over it several times like I did. Use a roller, roll on sort of thick. Wait a few minutes and use a scraper/putty knife. Scoop into a dustpan and then into a bucket. Best way I found to do it, and through lots of trial and error.

I purchased this product this morning, based on the reviews here, . By 2:00pm my bathroom floor was free of adhesive. I covered the first portion of the floor with plastic (as per the instructions) and 15 minutes later the old adhesive scraped off with very little effort. I did the next section without the plastic. More effort was required and the result wasn't as good as the first section. I redid the second section and added a few more square feet to finish the room, covered with plastic, and the adhesive came up with little effort.
The moral of the story is "follow the instructions and you will be very pleased with the result".
