Proper installation of large format tiles over NuHeat?


Bud, I appreciate your comments, which are generally spot on. In this case, I have to disagree, based on personal experience. My wife and I installed about 120 sf of stone tile on our kitchen floor using the Warmly Yours heating system (very similar to Suntouch). We installed Ditra over the heating mats, using unmodified thinset per Schluter instructions. We glued and stapled the mats prior to installing the thinset.

We had minimal problems, and neither of us are experienced tile setters. We did use plastic trowels to install the thinset over the mats, just to minimize the chance of damaging the mats. We also installed a loudmouth just in case, but there were not problems. The Ditra went on flat, and we installed the tile a day later with no problems.

I understand that use of SLC is perfectly reasonable, and may be easier for the average DIY installer. My point is that based on personal experience, we had no problems using the thinset - Ditra - thinset - tile approach which was recommended both by Schluter and the mat manufacturer.

A couple of tips perhaps from our experience. We precut the Ditra to fit, this worked well. We were careful not to damage the wire by walking on it, which in practice meant working the Ditra from one side of the room to the other, rather than starting in the middle. And we used a plastic toothed trowel to reduce the chance of damaging the mat.

I understand. DITRA on top is a little different. The DITRA would be the thing that helped to smooth the floor. In most cases DITRA wouldn't be necessary, just another layer of protection but overkill non-the-less.

WarmlyYours floor heating is a great product. It does have a very thin wire and I have noticed that the mesh now extends past the wire to help hold it down. I prefer to use SLU myself but agree with the poster that used Ditra over back troweled thin set is also an option. The comments that SLU costs so much more I may not agree with. The costs of quality thinset PLUS Ditra is about the same thing.You may tile directly over SLU. It is a cemetitious product and thin set will stick just fine. If you use a "soft joint" around the room any possible expansion will have minimal effect on your finished tile.

Proper installation of large format tiles over NuHeat?


Hi Wally-
So, I'm getting ready to install the NuHeat and I have one more question, going back to something Bud said. The mat we have is a standard size, not custom to the room, and there are a couple of places where there's no mat (under the vanity, around the toilet). Do you have a recommendation for how to build up the floor in these areas so the tile is level?
Thank you!

Testa- I have many of the questions as you. Except I'm put a wire system on concrete.

I was told an option is to put a border of hardiebacker or similar around the room where the mat won't be. This will act like a form for the self leveler.

Pol-
That sounds like a good option to me, but we'll see what Wally says, as I'm asking the questions not giving the answers! In my case I've decided not to use the self-leveller, so I'm thin-setting the Nuheat directly to the plywood subfloor, and the mat is only 1/8" thick installed. I'm not sure if I should just build up the extra areas with thinset, or find some other sheet or panel material that is 1/8" to raise those spots up to the same plane as the mat.....

Proper installation of large format tiles over NuHeat?


A key thing here is "LARGE FORMAT TILES." The larger format tiles require a
"flat in plane" surface. The use of SLU ( self-leveling underlayment) is the
BEST way to achieve this - either pro or DIY'er. I think Wally would agree with this statement for large format tiles. Nu-heat has the lowest profile mat and like the post just above this states, even the areas where the mat will NOT be, there is a concern to be able to get the floor flat.

Proper installation of large format tiles over NuHeat?


As a first-time tile job, I picked one foot square tiles. Every little mistake shows because tiles are perfectly flat and my floor wasn't. With tiles the size you are using, even the smallest bump will magnify. I have to second/ third/ fourth the use of SLU. It will give you a perfectly flat surface to put down your perfectly flat tiles. Trying to butter tiles of that size to account for the different thickness of your sub-layer is going to make your brain hurt and likely will be next to impossible to get right. If you do it that way, make sure you spend a lot of time with your level on each and every tile. Once one tile is not level you're in for quite the headache.

Floor vacuumed, scraped, vacuumed, mopped and then vacuumed. Making sure there are no bond breakers to affect the bond between the Nu Heat Heating Pad and the concrete board (Wonderboard Lite).



Heating mat also cleaned with a damp sponge and allowed to dry.



Laticrete 254 thin-set mixed loose. I added 20% more water than specified to get a loose mix.



Set and flat trowelled.

Nice Job John! - Hey I came up with another simple tool to convert your metal trowel into a plastic one so you are NOT concerned about damage to the floor heat mat IF you choose to back trowel thin set, like you did here. Contact me and I'll send you one.

Thanks Phil.

I'm good. Never hurt these wires ever with my steel trowels. Keep the screamer on and your good.

Saw your edge strip kits being sold here in Vancouver at Ames Bros yesterday. They where on sale for $3.00 each. What do they sell for State Side?

Thanks, That's a great price! They are twice that here. I know that Ames is doing a special promotion to increase awareness and sales. The ESKs and the BBB will be featured in the Dec. Tile Letter ( our stateside association publication) the NTCA - National Tile Contractor's Association. That's a big deal for me. - Sorry, took over this thread. We can communicate offline if you need anything more from me.
