Ha ha I just did a job like this ! Bathroom. I used the bonding agent, then floor levelling, then a glue down cork. Worked well !! Thanks for posting, as always! Great channel
Thats cutback adhesive and yes you can 100% go over it. Just read the bag whatever you are patching with like ardex. Do do not scrape or sand floor unless you know it's not asbestos
If you sand cut back it doesnt turn in to dust it just cakes up in to little balls and most patching leveling compounds that actually are "able" to go over cutback require you to scrape it to the concrete the glue ridges are gone. But where im from the home owner can legally remove asbestos products from their own home
@@bsmbB it cakes up a bit yes. Really you don't need to remove it unless it's thick. Personally I just patch over it with ardex like I've been the last 25 years Ardex you can go up to a 1/2 deep so you can just skim over it If you know it's not asbestos you can sand it. If it's thick sure it will cake up. Thays when you bring out the scarifying plate.
@@meetstepsisalcoholicdouche6167 ardex states in their surface prep tech sheet that cutback must be thin enough to apear as a stain on the concrete or it must be carefully removed. And you have to check with the adhesives manufacturer if the bleed through will cause the new adhesives to not bond to the patching compound if it will you are supposed to bury it with their leveling compound. I guess you been doing it wrong for 25 years
If you're like me and cannot get laticrete products in my area, the mapei ecoprim is a good product for the same purpose and works extremely well. Used it several times in this application and for plaster substrate for backsplash, (even though the Mosaic thinset says you can just go right over top of the plaster at the bond I do not trust it) and have had zero issues and great results
@@travismartin1915 live in a small town of 100k and only 1 home depot as their only big box store of that kind lmfao. I'll have to grab off amazon i guess
@@MV-wb2cz lookup bonding agent, there are serveral companies making them, stucco guys use it, painters, flooring guys etc. 100K town will have suppliers for these trades imo.
I'd be curious to see a 30 day bond test done with either ceramic or porcelain tile. My basement floor has cut back over every square inch, I removed the old linoleum tile when I moved in. I think I'll try it as I've been wondering what my options are when I finally get around to putting in a new floor...
We use razorblades scrapers first together ant loose adhesive off then use mapei eco prim grip which has a grit in it ;oops pretty much same as what you used and is dry in an hour ready for tile or Ditra. That is a pretty common scenario out here in the rust belt.
I removed old hardwood floor for LVT. I noticed after removing the hardwood floor that there is a vinyl floor beneath it. There is a significant amount of hardwood floor adhesive left on top of the vinyl floor. Do you think I can use this product to smooth the vinyl surface? Thanks
I have this mastic on my kitchen floor. I plan to just do a floating laminate but can I use this primer to seal the mastic before covering with the floating laminate and it be safe?
Damn wish I knew about this years ago... Anyone know if you can set tile over epoxy pebbletech floors and if this product could be usefull for that? my old boss had me tile over one 5 years ago and as far as I know it never failed, well I have another job coming up in a few weeks over one.
Isn’t that asbestos? In the Uk we most likely would think it was and they usually are on the back of the Lino tile too, although low risk but still would have got it tested and left alone and just screed over if it was asbestos
We tested ours. It had asbestos. Looked exactly like this. When researching what to do with it, all the articles I found said you need to prime first before screeding over. So I think this primer video is a great idea.
I used to work for a union tile shop in Chicago and delivered to all the job sites. Laticrete was a big one they used to always use. All the tile at Soldier Field and Palmer House was most likely Laticrete to set the tile with
80s adhesive made with asbestos, Usually people just grind the floor down until they get a smooth, uniform substrate. I’m glad there’s other ways to go about doing a tile job over this stuff. Laticrete should really sponsor isaac at this point lol
Will this work with sticky adhesive tile for a cheap route? But tried scraping old glue off and it's hectic in a room I'm doing. Or do I have to do like different tile to use the prime and bond
From the spec sheet: "When bonding to cutback adhesive or other adhesive residue. Adhesive residue must be wet-scraped to the finish of the concrete leaving only the transparent staining from the adhesive. Do not use adhesive removers, solvents or other chemicals that may penetrate into the concrete."

Do not install over any substrates, cutback adhesive, or other adhesive residue containing asbestos. Always verify it does not contain asbestos. I just copied and pasted from the Litictete site odf
Great video im having issues removing tile adhesive off a basement concrete slab...can i use this product right over it and tile using ceramic? Will it really bond to thin set?
I haven't seen that stuff in a while. I once tried to clean it up with paint thinner. What a mess! That was before the Internet and easy access to information.
I use the Mapei version of this. You can tell when tile was placed on top of the cutback because they sound hollow when you tap on them. The primer is very easy and simple! Thanks Isaac!
They also sound hollow when they're not installed properly... thinset skinned over, failed to back-butter, etc. One thing about tile over cutback though, is it's easy to remove!
Hi, been looking at uncoupling membranes. Was being steered to Blanke Permat because the claim is that it adds substantial strength to the floor in using the mat. Nowhere have I seen any comparison tests on crack isolation or strength claims. Loved your tests on grouts ,very surprising. Plenty of people using these uncoupling membranes but no comparisons. Saw Sal DiBasi's endorsement of Blanke Permat. We may all be surprised in a real life comparison of products in tests.
Often this stuff was mixed with asbestos. I hope you wore significant protective gear. When I dealt with it, I did the primer method (different company's product).
