Rated 5.0 out of 5.0 by RG Absolutely great
I had to take up an old vinyl tile floor to put down a ceramic tile . Under the old floor was a black sticky mastic . I called the flex bond thinset 800 number to ask if it would adhere to that surface . The rep said it wouldnt and advised to use this MBP primer . I ordered 2 gallons that was shipped to my home . It went on easily with a brush , dried to a smooth surface . It was even easy to clean the brush with soap and water . It even smells good . Indespensible to use on any problem surface .

Rated 5.0 out of 5.0 by LosRubios Great solution for sealing cutback tile adhesive, easy to apply and dries quickly
As part of a bathroom remodel, we removed some old vinyl tiles and ended up with the ubiquitous black cutback tile adhesive residue on the concrete floor. After consulting with Home Depot's 'Ask a Question' feature, the reps at CBP recommended we use this to seal the floor before putting thinset and ceramic tile down.
Application is very easy, just make sure the floor is clean and that the old cutback is removed down to the concrete using a wet scrape method (wet to keep any asbestos dust under control). We used a little leveling compound here and there and the primer stuck to anything equally well.
Mix up the primer with a stick for 30 seconds and then paint it on the floor. We used a 3" chip brush around the edges of the floor and a 3/8" paint roller on an extension handle for the main part of the floor. Took about 15 minutes to paint an 8' x 8' bathroom and used about 30% of the bucket we bought. During application it has a slight odor which is similar to although a lot milder than CBP's RedGard waterproofing membrane product.
We left it for an hour and it had dried from the bright blue it is when wet to a darker semi-transparent blue. As soon as it was dry, we started laying the floor tiles so this product certainly works quickly.
Clean up was easy with water however I would recommend wearing gloves as it dries quickly and can be difficult to remove if you get it on your fingers or clothes during application.

Where have you been all my life! Took up glued down wood flooring on concrete and even after scraping the mastic a film remained. Thought I would have to grind or use adhesive remover, but found this wonderful product and it is great! Two thin coats and ready for tile. Tile adhered like a champ. It saved tons of time and money. Love it!

Rated 5.0 out of 5.0 by Surlypud Perfect for old vinyl tile
The front entry way of my 1947 house had vinyl tile that was glued down with asbestos mastic. I decided tiling over it would be best. This bonding primer did an excellent job in one coat. I was applying thinset 2 hr after I rolled on the primer. The thinset really stick to the rough surface of the primer. I'm so glad I found this product.

Rated 5.0 out of 5.0 by Handyman Perfect for creating a bonding surface
I removed self-stick vinyl tiles applied to a concrete floor so I could install porcelain tile. After removing the vinyl, there was a very thin, tacky layer of adhesive left on the concrete that I could not remove by scraping or with adhesive removers. The only other alternative for prepping the concrete for the new tile seemed to be grinding it. But this product covered and adhered to the adhesive layer well with very little effort and provided a very good base for tiling.

roduct (MBP) permitted new tile to be set over old glossy tile. Apply MBP over the old tile with a paint roller, wait one hour or so until dry, apply masonry mastic (Flexbond, for example) and then set the new tile. The paint roller application of MBP creates a rough surface that establishes a good (rough) mechanical bond. I searched on the internet a long time before finding this product. I’m happy Home Depot makes it available.

I have used MBP on tile and it works great.I don't think I would use it as a sealer.
