I have a tile over tile job coming up. Existing tile - a mud job in pristine condition.

For those who have used this product, how did it work out for you, your experience with it ?

I've laid tile on tile, then decided I'd rather have a wood floor, glued that down then my wife came home hated the wood floor so I tiled over that!!! Love Eco prim!!

I'm curious whenever I have had to tile over existing tile I just grind off the glaze with a dustless cup grinder. How is eco prim better?

I've used it a few times on small bath floors. Floors have all been solid with no cracks.

I belt sand the tile to scratch the glaze and to remove the cleaning products.

I've ground off glaze,too. Eco is so much nicer.

To me it's the theory of say a wire mesh, just provides a better " grip" for thinset.
No I haven't used it yet, elastomeric with aggregate , something to that effect .
I still like to rough up surface due to possible bond breakers .

I used it on two floors back in December. So far so good. Almost too good to be true. Time will tell.

Thanks a lot for the input. I have to order it in the AM.

I used to belt sander to prep before. I think I'll just give a quick pass or so with a pad sander, wipe clean and apply.

Eco Prim is designed to grip a tiled surface. There's no need to grind tile before using. It's better because it is faster, cleaner than grinding and gives a great surface for thinset to grip to when installing the new tile.

You will more easily remove thinset from atop a tiled surface than you will remove Eco Prim, scuffed surface or not. I've gone through almost 20 gallons of Eco Prim and it's an incredible product. I have not used it to install tile over tile....not something I believe in doing but as a primer/bonding agent, it's the cat's ass.

Is this for real?

I got it, you want better bite more surface area to grip to. I guess they are recommending it for more diverse applications for just tile over tile. Can't remember but I think they recommended it in their moisture mitigation system as well.

It's not a waterproofing like AquaDefense is. You need to make sure any concrete surface is under MVER 5lb/1000 sq ft and it's good to go. But you won't use it on a shower pan.

It can be used as a bonding primer when tiling over a gypsum floor.

After the epoxy system then the Eco prim grip ? Interesting so lightweight concrete confirming all minimum standards are met using prim grip will work for a bond? I almost never run into gyp/con. But good to know.

Here you go. Finished this week.

I'm averse to new products mostly but I called Mapie and checked here. I've scarified in the past too.

It is an amazing product after it sets up --- how it sticks / grip to the glazed surface. I used 2 coats by the way.

Just making sure I understand what you are saying. I was a little confused on what you said you do. Are you saying you belt sand the tile to remove the glaze and then ECO?

Your last statement sounded like you were comparing grinding and ECO as two separate methods, but the belt sanding was in conjunction with ECO.

I have a tile job in a basement with concrete floors where carpet was pulled up. There was some glue residue in pores of concrete. I applied one coat of eco prim grip but seems to not be completly gray- can see through some of it. Do I really need to add a second coat to make completely not see through?
