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
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
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

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...
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!
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?
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.

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."

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.
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
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.
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?
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
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).

Thank you so much for that TC. Have an identical situation in my house and this infor will help much when it's time to fix the floor.

I do asbestos inspections and testing, that looks like black mastic. Those vinyl tiles can also contain double digit percentages of asbestos.

Can you put that directly on top of linoleum sheet flooring, or do you have to pull up the whole floor?

@@brianschrier6193 You have to pull up the old floor. The product is applied to the black cutback adhesive.
Cutback is asphalt based so treat like going over a hot mop.

So no Ditra is required for concrete? Is this stuff only for bonding surface?

So I can just roll on the primer and then apply thinset and tile it. Without adding an uncoupling membrane?
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?
That was vinyl tile not linoleum. Linoleum has a wood backing. Backing looks way different that was a old solid vinyl tile
you are correct!
@TileCoach if figure the Rubi DT 180 Evolution is probably discontinued, but is it any good getting one secondhand for cheap?
Hi can you send some pictures of my bathroom I need some help with renovation
I didn’t see you try to peal at it or pick at it with a scraper or a razor blade?
depends on what the subfloor is i imagine
Nice tip. 👍
What's the name of that saw? Looks just like the Ridgid. Great little saws!
Would this work for tiling over old carpet adhesive on concrete floors?
Is this product water sensitive like the redgaurd version?
Can this be used on a concrete porch outside that is covered and screened?
Make sure when you do this you always start at the door and work your way into the room.
Oh I hate that stuff! I have used a razor floor scraper and a respirator when removing. Old 70’s houses are full of fun 😏
Mine was built in 1960. I popped all the tiles off in one bathroom. Tiles are still on the 1/2 bath floor
Do you need uncoupling membrane?
If Laticrete guy said it would work . I will try get ahf if some for a very small bthrm and then check it with mallet in a week.
Did you touch the side of that saw blade or did it just look like it from the camera angle 👀?!
It was probably a one-tooth saw blade.
He was wetting the sides.
Why would you? The stuff can be removed with vegetable oil...
Any follow-up?
