Did the job well. Had a slab that was way too smooth for thinset, so painted it with this first.

Rating provided by a verified purchaser

Perfect for tiling over tile or any substrate that is too smooth or has glue residue, etc. MBP provides a nice, clean, lightweight and slightly tacky surface that thinset LOVES to adhere to.

Excellent coverage and adherence!

It's a good product but the price is outrageous i had to have it because my flooring supplier was closed at the time

Never heard of it before. But i had to use it in my new apartment so the mortar would adhere to the subfloor. I am a believer.

It worked as advertised

I used over asbestos adhesive residue. I poured self leveling concrete over it, seems to be doing well.

It worked very well for a job where we had to install porcelain tile over existing ceramic. It adheres well and doesn't raise the floor any more than it had to be (e.g. cover the ceramic with Durock etc.)

easy application. hopefully my tiles bond well to the surface!

Works great.

If used properly, this primer is an important part of your subfloor treatment.

Great product - two tile porches - one with hi gloss tile and one with some porous nature to it - followed directions - dried in an hour in Florida - then put two coats of Behr Slate Grey Porch Paint - Transformed our porches and the MBP provides a no slick surface - Don’t put on too thick - Every 100 sq ft use a new roller 3/8 inch - if you decide to paint also use a new roller 3/8 inch every 100 sq ft - we hated the tile and also the danger of slipping - MBP does the job !!!!

Worked great; used on Formica backsplash prior to installing a new marble mosaic backsplash.

Materials were available for store pickup as promised and on time!

It really adhered and dried very fast . One see trough blue coat created a hard ruff surface.

This worked as expected. Tiles holding well and all looks good.

My go to surface prep over cut back, tile, linoleum and other problematic substrates

I wanted to do a tile over tile project (kitchen backsplash) and was worried about the old tile not accepting the new tile. Found this MPB product and then easily/quickly painted on one coat of it over my old tile. It worked extremely well thereafter, using normal thin set for my new tiles. I’m absolutely amazed. Outstanding product!!!!!!!!!!!!!!!!

Good
