Can I put the Schluter heat cable type pad on an Oatey membrane? I prefer the continuous Oatey membrane for its waterproofing advantages. I am installing a curbless shower. Plan to recess my floor, cover it with tarpaper then a sloped mortar bed toward a linear drain. Membrane will go on top of mortar and direct water into the drain. I will use approved adhesive to hold the membrane securely. Pan will be approximately 60w x 36, not sure if wire mesh is critical in mortar? Trying to keep the height of the tile in the pan as low as practical after accounting for the slope and thickness of all the components. Hoping to hear that thinset between the Oatey membrane and the Schluter pad is acceptable. Please advise.

Thank you sir. Vary helpfull.

I’m kicking myself for not filling it in with the recommended un modified. I was told that I should be fine now though because it has had plenty of time to dry. At this stage should I still use the un modified or should I use the modified now that I have filled the waffles and wires in with the 254. I will be using 24x24 tiles what do you suggest that I use.

Unmodified thinset is a must and you will void any warranty if you don't use it. You can use regular ditra in the unheated areas, but Ditra heat is a little thicker than ditra, and a little thinner than ditra XL, so you might just want to use ditra heat membrane for the whole thing. Use only a premium unmodified thinset, like Tec Uncoupling Membrane Mortar, or DitraSet or some other quality product.

2 meters for reading resistance and continuity: when they die out on you, just replace it with a good multi-meter that will do all those and more.

Sal, I had my bathroom all planned out with Ditra Heat and now I read that it's not really for heating the room, just the floor. That's not something that Schluter makes apparent. It seems like a lot of trouble and expense to go through just to keep your toes warm. I'm wondering now if I should even bother. The mats are down, but I haven't installed the cable or thermostat.

As mentioned very briefly near the end, you cannot have, say 5 ft., of heating cable left over. This point I believe is highly critical and should have deserved much more discussion.

Ignoring local codes.. Is it possible for Ditra to eliminate the need for a second 5/8" substrate? For example if you have 5/8" floor, then it is typical (in tract housing) to install another 5/8" plywood substrate on top of that for tile. Of course the only reason we do that is to save money, and because the code requires it as a minimum. But I would guess that you would not need the second layer of plywood with Ditra. Am I right? Good practice or no? I can't tell if you are installing Ditra on a second 5/8" plywood surface or not. Anyway thanks for your generous videos Sal!

Val, the basic difference as I understand it is that modified thinsets are exactly that.. modified with agents to help bonding between your tile and substrate (cement, osb plywood, etc). the replaced unmodified thinsets many years ago to aid in bonding, drying time, moisture control, etc. (seemed like a marketing thing to me at that time). It also changes drying time and integrity of the mortar bond/strength, and the reason for "non modified" for tile to coupling membrane is that Schluter has designed it to set tile better with non modified. The under side uses modified to grab the felt backing and bond to OSB flooring. Note concrete uses different mortar than wood. I would ask a Menards associate for examples of each type they carry, then do your online research about how good each is or find reviews of them.

Jared Waterman Val, here is a good review of "unmodified thinset reviews" for tile to ditra membrane install. floorelf.com/unmodified-thinsets-a-users-guide

Is this a kit??? At least the wire and thermostat?

@SalDiBlasi

Usually you buy the wire mat and thermostat separately. but I think you can get them as a Kit also. www.amazon.com/dp/B00JVTJSOU/_encoding=UTF8?ref=exp_inf_pl_saldiblasi

Thank You!

since we are talking about thin-sets, what is your opinion of Custom Building Products Flex Bond Morter for membrane to OSB substrate? This seems to be what the gurus at Big Box Store recommend, though I don't always trust their opinion. The non modified mortar recommended was Custom Blend unmodified thinset mortar. Your opinion for durability and quality is appreciated.

I don't use Custom building products, I don't like them, and I would never trust the opinion of a sales clerk.

***** Thanks for the opinion, as I don't trust sales clerks either. Is there a better choice available at a Lowes or H.D or should I shop at a tile place? How about performance on Prolite thinsets?

Not a problem, in fact if you have a run of more than 10 feet it is recommended to do just that to give a break to that straight run

I was wondering, why the heat vents weren't removed or at least the one on the floor in the main traffic area rerouted into the wall so that some one in bare feet wouldn't trip on it. Doesn't this system produce enough heat to comfortably heat this room without the use of a forced air system? I am converting an attached single car garage into a bed sitting room and am exploring various ways of heating this space as I can't run forced air without open the floor to the main house easily. I like this system but if it doesn't produce enough comfortable heat I may have to look at baseboard heating instead. I would appreciate your take on this. Thanks and very good video by the way.

Most electric floor heating systems are only to make the floor comfortable, but do not produce enough heat to function as a primary source of heat.

Thanks for your reply....guess I'll have to go with baseboard heating of some kind.

Sal DiBlasi unmodifed for the membrane over plywood ? And modified over concrete

Modified to install Ditra on plywood, or either to install ditra on concrete, unmodified to install tile on Ditra uless you use Schluter Allset.

Wouldn't you have a problem with the thermostat next to a heating vent supply.?

The sensor is in the floor, the thermostat is the control unit.

Sal, I am so confused over the unmodified and modified thin set situation. I am laying Ditra Heat membrane over plywood and then 16x16 travertine. I know that I need polymer modified thin set on the plywood under the Ditra Heat and unmodified on top of the Ditra, under the travertine. I have a local Menards store and there are so many choices. I found TEC Full Flex Premium Latex Modified Thin Set Mortar which looks like it will work under the Ditra, but also found TEC Uncoupling Membrane Mortar which says it can be used with the Ditra and many more choices. Can you please lead me to some exact brands or model numbers? I cannot fine anything that specifically says unmodified and don't know what the means exactly. I don't wan't to get the wrong ones.

@SalDiBlasi

Full flex is good to install the ditra, and the TEC Uncoupling Membrane Mortar is good to set your tile on the ditra. In other word FullFlex is modified, and TEC Uncoupling Membrane Mortar is unmodified, and is the one i always use. If you look at the bag you will find the Schluter logo on it. It is called Uncoupling Membrane Mortar, because Ditra is an Uncoupoling membrane. If you have not seen this video, it might help you understand, kzread.info/dash/bejne/i6SMp7qqksudn84.html

The floor was scrapped and clean, what you see is a little bit of thinset residue that could not be removed from the previous floor.
