The Tile Counsel of America manual shows how to tile over tile. Been doing this for almost 40 years. It's only done when the original floor is secure to it's base otherwise tiles pop. How to find out? Use a regular nail puncher and tap every one of the tiles you will work over with to see if they are secure to the base. A hollow sound tells you it isn't and a hard thud sound tells you it is. If it's a floor, every tile in the traffic area must be secure to it's base. If you tile over an area where a tile is not secure to it's base there is a high risk of cracking, especially when something is dropped on it. Once you do a tile over tile job it limits you to future repairs especially when different format tiles were used in the same space. We used this method mostly for commercial applications such as restaurants where downtime was a very important factor for the client.
I used it on a vertical surface tile over tile. Works great! even works with mastic. If you're only pulling straight in and out of a garage I bet it would work fine, but if you are turning your tires I bet it will start to wear out over time. Also not sure how it would soak up stains or how easy it would be to clean.
Quick question, would. Need to use this product if I’m only tiling over one tile (18”x4”)? Made a miscalculation on the bottom piece of a shower niche, unless I find a smaller tile edging piece, looks like I might have to resort to put a another tile over the one that’s been laid in already…
Starr tile, i'm getting ready to undertake a remodel . i'm demo'ing my shower and floor tile and having someone put in a tile shower with a tile pan and new tile floors. what kinds of questions should i be asking of the tile companies? also baseboard down to concrete or baseboards on top of tile....is it purely aesthetics or is there a reason to do one over the other?
Great product, thanks for sharing. Just to be clear, by using this product I would be able to skip the step where I'd use a grinder or sander on the existing tiles, right? I saw people doing that in other videos, especially if the tiles were glossy, but this method is way better.
The adhesion is amazing and the grit is like the not slip paint. Next time instead using a brush, use the small 4 inch roller it would be so much fast. Not the regular diameter one but the thin one I think it's 1 inch in diameter.
You mud joints, screws and corners for green board on shower walls before red guarding. Do you use drywall mud or thin set? Does regard stick to the drywall mud good enough?
It looks great, I love the idea of going over the tile. It saves so much labor! One question, how will the dishwasher go in and out with the floor being higher?
As a rule there is usually at least an inch between the two tabs that anchor dishwasher to your countertop and the dishwasher itself... so you have room to do that regardless of the little half an inch you will be adding. Tile goes up to legs and front plate covers that.
My husband and I are about to do a DIY shower remodel. We have a similar situation with existing floor tile over slab on grade, however we're also in a flood plain and when we do get flooding, water seeps up through the concrete foundation and up through the tile grout. We want to tile over the existing tile but also waterproof it so it no longer floods in that manner. Should we use the tile primer and then red guard over it, or just red guard and skip the primer? I know this is a unique situation. Thanks for your help!
My suggestion is using primgrip only, I believe it has waterproof quality with it...test it to be sure. If transition isn't an issue I might regard old floor, thinset over it with 1/4" durock on it, then tile over new backer...probably could redgard over new backer too prior to tiling.
Once its dry which takes about an hour or so , but I would defer to the instructions to be sure. I believe on this job I had waited overnight before I tiled
I don't trust anyone's tile job enough to tile over, I had costumers asking me to do that before. Also if you're pit the levelers on the corner of the tile you don't need to use that many. Looks good!
Would you recommend using this product on a shower stall wall? Original tiles are installed over a cinder block wall and too difficult to remove. Can it handle all the moisture?
Nice work! I’ve always been skeptical 🤨 about tile over tile. Feels like I’m breaking some tile law. But I suppose with proper preparation, it’s not that bad. I installed same Home Depot tile in my customer’s laundry 3 weeks ago. In my experience all clips break off well, unless they are encapsulated in thinset mortar. When I get thinset on each side of the clip, it has nowhere to go, thus resulting in surgical removal with razor knife.I have used Rigid Level Max, Lev-Tec, and no name Amazon clips. I use grout removal blade on my oscillating tool to carefully cut through the plastic clip stub.
My new tile will extend under the new vanity. The existing tile did not extend under the old vanity. Do you know if I could use regular tile cement to bring the level up to match the existing tile level?
do you think you could use that product on a porcelain tile outside to where you didn't want it slick and paint over it instead of tile over it without any problems of peeling?
Well I tested it with a 6 in taping knife and it's very difficult at best to make it come loose but it will definitely not peel, I would suggest calling the manufacturer and getting their take
@@StarrTile Thanks for answering back. I did contact the manufacturer and for some reason they couldn't or wouldn't put me over to a tech person and were really no help.
Quick question . New shower and contractor put osb as main floor and then started to poor quickcrete to make his slop he did not redgaurd or use sometype of water membrane blocker . Is this correct . It’s on the second floor and honestly this is a 35k 9 foot shower with Brizo trim ... I just need to know if this is being done correctly ?!?!? Thank you
I answered your question on the other video, using overlaps tar paper before the Quikrete, I would also strengthen it with a polymer additive or some shredded fiberglass that comes in a bag, you can mix it with the Quikrete to make it stronger
@@skincarving most of the homes built nowadays is OSB on the floor, on the side of your house, even on your roof , so it's not the board per say it's how you protect it.. as I said already overlapping tar paper should be used first to protect that OSB floor from the moisture
Good to see this work. I'm going to be tiling over tile in my own bathroom. I did the tile 12 years ago (my first big bathroom job)--small "classic" tiles, lots of white grout. It's never been clean since. Now I want large format floor tiles, channel drain in a wet room shower. Is this stuff rated for a wet area?
It might.. as long as those are adhered very well because when you married the thinset and the tile together then it becomes a problem if anything below moves
This was a larger than normal baseboard, instead of the 2 and 1/4 inch I believe this was 3.. the customer was given an option to take out and replace later and they declined, in fact even when the job was done they didn't want the quarter round back on the baseboard...but yes undercuts on jamb were done
Prim Grip is alot like Redgard, I believe it has crack prevention properties...and may even repel water, I should test that. Feels and acts like all liquid topical membranes except it has a gritty texture, I think silica
Hi Bob, been a follower for several years. I’ve never needed to research tile on tile applications until now. We have a 600 sq ft open living room/dining room area and even though the tile was done nicely, we knew there were some bumps. But when i went to lay my custom cut hand oiled poplar baseboards, it was apparent that I couldn’t get a nice fit without fixing the floors. Have kind of decided to sacrifice 3/4” loss of floor to ceiling height to avoid a filthy demo of old floors and since my door transitions have the room. Question to you is, I need to do a leveler in certain spots to get my edges straight for baseboards, so should I use the leveler over the existing tile without any other preparation and THEN lay this Mapei primer? Or will it be necessary to scratch up the surface of this old stuff before leveling and priming? Can you advise me on a clear cut order of operations? Will def hit your Patreon with some love. Thanks for such a great channel.
PS: I did definitely consider some coping and back cutting of my baseboards but I’m pretty sure nice level floors is the only legit “Pro” direction to go. Cheers
If it were me I'd use self leveler on only areas needed that are depressed, then rest of tile use prim grip...or thinset 1/4" backer on entire floor after filling depressions, assuming height at doorways not an issue. Baseboard I'd replace, that's just me though.
installation instructions for Custom Building Products Redgard state that it can be installed over their Multisurface Bonding Primer, which is similar to Mapei Eco Prim Grip. Based on that, I don't believe you can do that.
Man, If i was the guy removing that new tile and find the old shit underneath I guarantee I would be cussing up a storm lmfao “who the fuck tiled over tile!!!!!!, god damn it!” Lol i could imagine how crushed I’d feel i didnt even know you could tile over tile lmao.
I never said I don't use or like them, I've stated I rarely use them but they are a "tool" when needed. With low end bowed tile set in half, SLS is almost required.
There can be a edge strip that can be finish nailed where the tile meets the baseboard. Then it would basically look exactly as if the baseboard was put in on top of the tile. The overall baseboard height might look short though.
If the owner specified it be done this way, then you have to roll with it. But when and if they (or a future owner) decide to replace the baseboard (to give it a normal height appearance, at minimum) wont’t it be really hard to remove without damaging the tile?
@@tscoffey1 I believe this baseboard was The Wider 3 and 1/2 inch and not the standard 2 and 1/4 baseboard so to the eye it is not that bad... removing it in the future will not be a huge issue although a bit difficult... and yes I always give options to my customers and they either accept or decline and in this case they declined not only changing out the baseboard but also putting in new quarter round, their choice not mine

Thanks for the video, perfect timing my next customer wants this done, looks great
Love that product. Used it a couple times for new backsplashes in kitchens where the demo would have been to risky for the cabinets.
Awesome video as usual. Really demonstrates the value of a useful product.

This what i been looking for ... will give my floor a shot ... the cost of removing old tile is roo much .. thx
Great job Bob always a pleasure watching your videos they have proven to be very informative.
Thank you, much appreciated
good presentation, thorough and to the point, good work !

I need to ask you a question can we use this over painted floor so we can do epoxy over instead of sanding the painted floor?

Can I use it on the wall with any size type of tiles ,marble ,granite ?
interesting Product Must see if i can get that over here
Like always all the information i need in one solid video!!
You mud joints, screws and corners for green board on shower walls before red guarding. Do you use drywall mud or thin set? Does regard stick to the drywall mud good enough?
I use mud if I'm using green board, I use thinset if I'm using cement board, and yes redgard sticks to everything
Will the surface tiles crack? Any feedback on this product?

Can you do tile over tile on a kitchen backsplash? If so can pencil tile or subway tile be put over a tiled wall?
Yes..you can tile over tile on a backsplash, though not recommended because of the issues of thicker areas around outlets, sides, etc.
Would this work in a bathroom because of the toilet flange?
Thank you, my main question is where do you get that transition strip? When title over tile?
Depends on the transition...Home Depot has most of them
You can use it in granite to and tile over
That would probably good for terrazzo tile over
Hello can i ask. How long you have to wait after you paint the eco prim on before you can put the tile on ?
Once its dry which takes about an hour or so , but I would defer to the instructions to be sure. I believe on this job I had waited overnight before I tiled

With what you described I wouldn't have any compunction about using it on walls
@@StarrTile Would scuffing up the original tiles improve long term bond?
The Tlock master clips don't break away very well!! 2 out of 5 break above the tile, I am having to cut them with a knife :(
Agreed..using a razor knife to get off the top portion is a pain.
@@StarrTile use lev tec
@@adamh6190 yeah we'll give them a try

My new tile will extend under the new vanity. The existing tile did not extend under the old vanity. Do you know if I could use regular tile cement to bring the level up to match the existing tile level?
yes you probably could but I would use tile... because it's under the vanity it won't matter if it matches up, it could even be scrap tile
@@StarrTile That's what I was thinking. Okay, thanks!
Awesome product..can be used as a primer under mapei self lever over plywood.

Hey man great job on the videos. Will this primer work over vct tile??
It might.. as long as those are adhered very well because when you married the thinset and the tile together then it becomes a problem if anything below moves

I'm the first liker😂😂😂😂thumbs up....thanks for the video I am soon remodeling my kitchen tile cause it got to go..... Thanks much..... Subscribing
Thank you !
How much sq ft it cover
Could you tile over vinyl that is very well glued?
No...you'll need quarter inch backer board
Any problem with reinstalling the toilet with this? Or did you tile around the existing toilet?
I never tile around a toilet
Hi.Do i will have any problems with reinstalling a toilet bowl after the floor is raised?
Every job is different, you shouldn't have because a tile and the thinset amounts to about a quarter of an inch , that's hardly nothing
StarrTile Thank you Sir.
hey will that prim grip work over carpet?
vaccuum it first
By doing it this way, does it not leave a little step into the next room?
Yes but there are various transitions strips that will overcome it
StarrTile thanks. Be interested to know which ones.
Use regular adhesive as usual after this is done?
Yes..thinset
Does the home depot carry this product?
I believe so
Minimally helpful..low/high spots, etc?
Hey Bob, would you recommend applying redgard on top of this primer before setting tile over tile to add waterproofing but also crack prevention?
Prim Grip is alot like Redgard, I believe it has crack prevention properties...and may even repel water, I should test that. Feels and acts like all liquid topical membranes except it has a gritty texture, I think silica

Not sure...not even sure why one would want to
installation instructions for Custom Building Products Redgard state that it can be installed over their Multisurface Bonding Primer, which is similar to Mapei Eco Prim Grip. Based on that, I don't believe you can do that.
How is it holding up since u installed it?
As far as I know I told you great, haven't had a call back
So what happens when you transition to carpet?
Many many choices from marble transition to schluter aluminium profile to oak wood transitions strips...really depends on what one wants.
Man, If i was the guy removing that new tile and find the old shit underneath I guarantee I would be cussing up a storm lmfao “who the fuck tiled over tile!!!!!!, god damn it!” Lol i could imagine how crushed I’d feel i didnt even know you could tile over tile lmao.
can i do this around bathtub?
If it's solid...I wouldn't though
You can... first use eco prim grip
And aqua defense
Abd then apply the tile
Make sure the walls are solid and free of mildew
Why the leveling system? I thought you never ever used them and didn’t like them?
I never said I don't use or like them, I've stated I rarely use them but they are a "tool" when needed.
With low end bowed tile set in half, SLS is almost required.
StarrTile My mistake. I know you had a video a while ago, thought it was about how you didn’t like them.
What kind of green do u blaze
How about old linoleum
Nooooooo..never
Been tiling for 40 years...never have I tiled over tile......wow
Agreed...and is why I prefaced by saying it is NOT ideal
I tiled right over a dead body once.
You don’t need a second coat unless you want to add extra coating.
So why was the baseboard left down? Is the new tile just going to be flush against it?
Yes the tile butts right up against it, my customer did not want the baseboard removed & replaced

why does everyone call this prime grip? its Prim grip. there's no e
Possibly I missed it but the only thing I saw you do was put down primer in terms of putting tile over tile I've learned nothing
The point of the video was to show how much reliable would be to use tile over tile
Holy moly, pity the fool that demos that, never installed tile over tile
Haha spacers for noobs
Actually only noobs install without them.
