Sal, you are absolutely the best KZbin source regarding tile and installation of tile. There are others in your KZbin community of tile installers that give some good advice, others share experiences to disseminate 'good practice' and some pitfalls in order that one might prevent the same, however some others are ego driven and don't follow directions or ANSI standards and remarkably proclaim themselves to be on the leading edge of it all (I think you know who I'm talking about), but it's refreshing to come across someone that really knows their 'stuff' and it shows in the end product. You do some absolutely beautiful work....

[@katoom-ju6vo]

Thank you for sharing your knowledge and expertise with us Sal. I was hoping you may be able to weigh in on an issue i'm having though. I'm gearing up to do a DIY install of 12 x 24 porcelain tile over Ditra on my concrete basement floor. According to Shluters instructions, I need to use an unmodified thinset between the concrete and the Ditra and also between the Ditra and the porcelain tile. Here is my dilemma. My unmodified thinset instructions (Laticrete 317) say that a latex additive is required when using it for porcelain tile which now makes my unmodified into a modified thinset. The Shluters instructions also says that its "ok" to use unmodified thinset with porcelain tile which is in conflict with my thinset instructions. I'm in full agreement with you as far as always read the bag and follow the manufactures instructions, but the conflicting information between products in this case has me a bit puzzled and not confident in moving forward with the project. Any insight would be appreciated. Thank you in advance.

[@SalDiBlasi]

That is an issue that has long befuddled many installers. The 317 is an ANSI A118.1 mortar, unmodified, and can be used as schluter says without the additive. The thinset will adhere to the porcelain tile without the additive, because of he extended curing time. I have used it many times. However that problem has been rendered irrelevant, advancements in Dry Set Mortar technology have made it possible to use newer modified mortars for setting the tile on Ditra. That is why you can use Schluter AllSet which is an ANSI A118.15 mortar to both install the Ditra and Set the tile. Mapei and Laticrete have a list of Modified mortars that can be use to set tile on uncoupling mats. The 317 is an older adhesive, and the additive is also an older technology but still very useful, and relevant in some situations.

Hi Sal, I'm going to do my own bathroom tiling project on the floor and walls (porcelain tile on the floor and concrete floor, walls are still TBD). After seeing your video, I looked at the thinset I bought on sale at Home Depot and it's unmodified and only good for ceramic tile. Back to the store it goes! Thankfully, I hadn't opened it and am keeping all receipts organized. It sounds like a modified ANSI 118.15 thinset would be best. I'll check out the Mapei LFT (did not even know LFT stands for Large Format Tile until watching your video) and others at my local tile store. I'm guessing I might need a membrane of some sort, too, and maybe to level the floor first but I'm getting to those vids.

Hi Sal, thank you for sharing your expertise. I live in a 1960 high-rise, where my walls are all plaster. My kitchen walls are primed with Iron Clad, an old oil-based primer from Benjamin Moore. The backsplash is square and plumb, and I want to tile it. My tiles are 2" x 2" American Olean ceramic on 12" x 24" meshed sheets. My local tile supplier, who knows my building, recommended a Polymer Modified Thinset Mortar that is manufactured in NYC. Sadly, Covid ended both businesses, and now I need another mortar recommendation. The Schluter All-Set looks interesting, but I don't need Ditra or Kerdi. I'd like a mortar that is easy to work with and gives me plenty of work time. Can you recommend something for my plaster walls? Thank you.

[@KJ_nyc]

@@SalDiBlasi Thank you, Sal, for responding. However, the link you provided is a newer edited version of this same 3-year-old video, which I already watched from beginning to end. I totally understand the details. My father was in construction. In both videos, you do not mention plaster walls or tiles that are attached to meshed sheets. Since you are in the Boston area, I assumed your business has some experience tiling in older apartment buildings that do not have plywood or drywall substrates, and have only plaster substrates. So I was looking for expertise in the plaster substrate arena, and I was wondering if Schluter All-Set could be used without the Ditra or Kerdi? Judging by their videos, the All-Set looks like a product that I might enjoy working with, accept they claim it is specifically designed to work with Ditra and Kerdi. If you can't or won't recommend a specific mortar for my application, I will do more research.

[@SalDiBlasi]

Allset is an A118.15T mortar, any mortar with that rating has the same properties. I favor the light weight mortars, which allset is not.

[@KJ_nyc]

So the research is leading me to consider the Ardex x77, even though the price is insane. I really like the lengthy Pot Life and Open Time. I also like their formula for smaller batches, since I have no desire to mix the whole bag at one time. Do I really need the Ardex mixing paddle (also ridiculously expensive)? I already own the QEP paddle. If I begin the mixing process while adding the powder to water, I should eliminate the risk of corner build-up. Any thoughts?

[@alexgrubb6640]

Schluter All set is ANSI 118.15 as well as Mapei's Ultralite is 118.15. Does that mean they are comparable? Im planning of using the Ultralite to set my porcelain over the Ditra mat instead of using an un modified

Hey Sal, been a while sir! Hope all is well in these challenging times. I’ll be brief in my inquiry as I know you’re very busy. I’m splitting hairs with a gentleman about mastic. I would like to provide some documentation as to why we do not (as professionals) use mastic to set tiles in a shower. I’ve searched ANSI TCNA and can’t find anything concrete. I’m about 99% sure on this but I believe in having facts to support. Your assistance would be a huge help Sal! Thank you and God Bless you and your family.

[@SalDiBlasi]

Well here is the thing, technically, type 1 mastic can be used in an intermittent wet area, you will even find it on the label of the buckett. However it is not considered a good adhesive as it will deteriorate over time and is limited to smaller tiles and cannot be used over waterproof substrates. The ANSI standard for Mastic is ANSI A136.1 Since it is an organic adhesive it does not do well in the presence of moisture. here rae a couple of articles www.tiletools.com/mastic-vs-thinset-use/ and www.mapei.com/us-en/mobile/tech-talk-post.asp?IDPost=125 Another point I would make, is that anyone that knows anything about installing tile, knows that mastic is a product to be avoided in applications where water will be present, anyone that has ever torn out a failed shower installed with mastic has no doubt about the limitations and drawbacks that mastic has.

[@markguagenti1126]

Sal DiBlasi thanks Sal. That was the “debate”. He seemed to be hanging on to the verbatim of “not in a submerged area or one of high moisture”.

Hi Sal Would I be able to use the Schluter all set thin set on hardiebacker board on the wall with out using any of other Schluter product with 24x12 Porcelain Tile thanks

[@SalDiBlasi]

AllSet is an ANSI A118.15 Mortar, it can be used for most applications regardless of schluter products being used.

[@dustinscroggins3382]

Great video sal

[@errik96]

So if i was using ditra and a 12x24 tile i should use a unmodified LFT thin set right? Do they make such a thing? Seems all LFT thin set is modified. Thank you.

[@SalDiBlasi]

They actually do, however since this video was made there has been some advancements in modified mortars, so now there are many that can be used to set tile over Schluter Products. Schluter even make their own thinset now.

[@errik96]

Sal DiBlasi thanks! I was looking at Schulter all set. Do you think that’s good for 12x24 tiles. Thanks.

[@SmittyFan]

Question. (Slab floor) Tile manufacturer for 2 inch 6mm thick mosaic hexagon for shower floor, says to use premium un modified white thinset. Redgard says to use polymer modified mortar. Which one should I use?

[@SalDiBlasi]

On a liquid applied membrane use a modified thinset.

[@SmittyFan]

Sal DiBlasi Thankyou kindly. Love the videos.

[@johnlennon2163]

Can you layer modified thinset to fill voids? If so how do you need to wait between coats (layers).

[@gregtaranto]

I watched your wet shim video. Good stuff! Can I use Kerabond unmodified to wet shim my kerdi board?

[@SalDiBlasi]

no, must be modified.

[@davidciriello5942]

thanks for the reply good info.....

[@SeattleLSB]

Would you suggest LFT for 6x16 ceramic? Or is Schulster All Set fine?

[@SalDiBlasi]

Schluter allset is an LFT mortar

[@eduardodedios8213]

So what thinset is best for thin brick venere on rock board for exterior? I’m more confused now

[@SalDiBlasi]

Se what the thin brick manufacturer recommends, then use that.

[@rayray2877]

In CANADA, We install tiles under Tile Council of Canada. What's the difference?

What would you charge for a complete bathroom reno?

[@brandonphilbrick3180]

Some tile installers around my area use proform all purpose joint compound for installing tile. That seems weird to me. Is there something I dont know about it where its doable to use it?

[@SalDiBlasi]

Joint compound is for drywall not tile.

[@jamesmcbride2929]

They are just using empty joint compound bucks to mix up the dry bags of thin-set.

[@jamesmcbride2929]

Buckets*

[@davidciriello5942]

HI SAI AWESOME VIDEOS *** IS IT TRUE YOU CAN USE A MODIFIED TIN SET ON DITRA WHEN YOU FILL IN WAFFLES THE DAY BEFORE AND LET IT DRY !!!!!

[@SalDiBlasi]

Usually yes. however today there are modified thinsets that will cure regardless of the substrate. Schluter AllSet is one, and others as well. However if you want to preserve the warranty always use a mortar approved by the manufacturer.

[@grizzly8859]

Schluter is the only company in the world that says You must use unmodified. Every other company with the exact same product different colour says to use modified. Using unmodified means extra percussion using the tile not the product ( back buttering)

[@timjones1583]

Should concrete be sealed before putting tile down??

[@SalDiBlasi]

absolutely not, in fact if it is sealed it needs to be scarified to open the pores.

[@danielfeldman7913]

Great Video! Sal, would Schluter All-Set be appropriate for setting 12x24 porcelain on a ceiling, on Kerdi board?

[@SalDiBlasi]

yes, done it ay times.

[@danielfeldman7913]

@@SalDiBlasi Great! Wasn't sure, as I had thought All-Set has a slower curing time, which may not be ideal for heavy tiles on the ceiling.

What would you use for cement board going on top of OSB?

[@daversj]

Use ditra instead of cement board. It will let the tile expand differently than the OSB subfloor. Use additional layer of plywood if the floor needs stiffening for deflection.
