Great explanation of different thinsets, anyone that actually watches the whole video will be well informed.....however, I take exception to your statement @3:45 when you say a failure of a tile job was caused by using the wrong thinset, there were prob mitigating circumstances but I would love to SEE evidence a tile fell off simply because a modified was used where an un-modified was called for...or vice versa...

By the way I enjoy your channel and am already a subscriber for many months now. I love the walk throughs that you do of the bad tile jobs From other contractors.

Good explanation of ansi Jeff 👍🏼 more people need to understand ansi.Best example I’ve seen is mix 1 cup non modified thin set and 1 cup modified thin set put both separately in a ziplock bag sealed tight leave overnight and guess which one is rock solid? That’s when you’ll understand why schluter specifically calls for unmodified thin set.

Wow bro! You did an outstanding job on explaining everything! I’m a DIY guy for my own home remodeling. I’ve got a collection of YT videos then finally going and looking up the ANSI recommendations and everything was as clear as mud! Then, I come across your video. Everything clicks now! Haha, Thanks for your experience and knowledge!

Jeff this was a really great explanation regarding thin-set mortar, and how to read and understand the labels-even if someone is NOT a professional contractor! Thank you!!! I was very interested in your video as well since I was trying to understand the differences between Mapei products (adhesives and grouts) for my mosaic projects. Since I live in Italy and am having a hard time understanding which Italian products (thin set, Mastic, Mirror Silicone adhesives, etc.) I can buy and use for my mosaic projects that are equivalent to ours in the U.S.A. You can't imagine how difficult it is to translate everything and try to find the same- just to do a project! They do not have a market for 'projects', nor are they big on DIY home improvements, so their 'home improvement stores' are extremely limited in what they carry and product diversity! So, unless you're a professional, know what you're doing, and have access to needed products, it can be a huge hardship. I recently found Mapei products (which is a famous Italian company), but I'm having a hard time understanding the differences between all their products (their package explanation is very vague and repetitive), and which one is best for me to use for my mosaic projects. I loved your explanations on the 3 Mapei products!! Could you please tell me, if you know, the differences between Mapei UltraMastic III or 5, and Mapei Adesilex P22, and for what exactly they are best used for? Those were the products some Italian artists were using here for their mosaic projects; they were using ceramic tiles, stained glass tiles, and smalti on wood, cement, and other base substrates. I would like to better understand in which situation and for what material these Mapei products could be (properly) used. Are any of the Mapei products the equivalent to our U.S.A. thin-set mortar? Also, on the Mapei Keracolor S, sanded grout, you explained that it was modified with polymer. Could you please explain what the added polymer is good for, and in what situation I would want that in my grout? Does Mapei have other grout products that are not sanded or are sanded but without the added polymer- and in what situation are those better to use? Thank you for all your professional advice! I look forward to watching more of your videos. I think you could write a well-advised and easily understood book on creating mosaics; small tile projects that would be a best seller!

i don't know anything about Mapei UltraMastic III or 5, and Mapei Adesilex P22, but if you email MAPEI, they do answer you. I steer clear of mastics, only thinset mortar should ever be used for tiles ever. Mastics often don't cure, and fall apart in humidity. Grout modifiers are for thigs like crack prevention, and sealing the grout to minimize water absorption. They probably have unsanded and unmodified grouts, but yo will have to seal the grout afterwards, and every 5 years.

Thank you for this! I got the Kerdi board - and I researched that you'd have to use the all-set purpose Schluter modified, or an unmodified thin-set. The big box store I was at had a ton of products, and I could not tell which one to get, and for some reason.. they didn't have the Schluter brand there either. I watched your entire video in the store, and ended up walking out and going to a different store, they didn't have un-modified! Really glad this was out there.

@@jeffostroff Tell me something else if you know. For kitchen tiles I used a premixed Mapei Ultramastic ECO (ANSI A136.1). This one seems to be stickier than thinset - I remember from when I was a kid that folks used to add wood glue in thinset to make "tile mortar" (grew up in Eastern Europe). Do you have any idea if it's still the case with A136.1 and how does this compare with A118.15T? I have to lay some 12x24 tiles and I don't wanna make a mistake. Also, is the membrane a must? I'm laying it over concrete in some storage underneath the stairs: we want to make a nice storage are that's easy to clean, so we're finishing it with ceramic tiles, paining the wood to seal it and whatnot.

@@cubul32 I don't like Mastic of any kind. They are glues (technically called organic adhesives in the A1361 spec.), but they are NOT mortars, they are not cement, they are a different animal. Mapei Ultramastic ECO is a Type 1 A136.1 Adhesive, and guess what, you tell me you have 12" x 24" tiles, you can't use this product, it only allows up to 6" x 6" tiles on floors, and 10" x 10" tile son floors. MAPEI may be better than other brands of Mastic I don't know, but the few I tried in the fast were dismal failures, they don't dry hard like mortar, and they don't seem to want to cure either. I can't even imagine anyone using it for floor either. They are not mortars. So there is still movement under them. I used a mastic from in a small container from Home Depot 3 years ago on a linen closet thinking it won't be that bad, no one will walk on it, but 3 days later the tiles can still be wiggled! I swore that's the last time I will try using mastic. All the best tile experts you'll see warn you NEVER use mastic, I have no clue why they even make it. For me, nothing beats tried an true mortar with a good latex modifier. The A115.1 spec refers to an "improved" latex modified thinset mortar when compared to A118.4 or A118.11 modified thinsets. It's simply the best of the best of modified mortars, which Schluter Allset is an A115.1 and LFT. If you plan to use MAPEI, go with their Ultraflex LFT modified tile mortar for large format tile, which you have. Great product, I used it sometimes myself, it resists sag (A115.1TE) on their spec: www.mapei.com/public/US/products/BR_A118.15-EN.pdf

@@jeffostroff I got LFT indeed, same mentality here - the package got a makeover here in Quebec - they call it Large Tile Mortar now (www.rona.ca/en/ultraflex-lft-tile-mortar-21085482). As far as I was reading, the Mastic needs space to evaporate, kinda like Schulter and modified thinset. Mine was 1ft sq or so; but it's mostly under the furniture and a bit under the stove (so it's there for the look in the 1/8 crack). So: I'll be fine. Lesson learned; thanks to you, thank you :) . The more I DYI the more I get serious and start researching and preparing. edit: my board dried in 2-3 days fyi - I could tell it was moving after 24h, really got me worried. Now trying to figure out grout sizes. I could only find a leveling system for 1/16 (Rubi - looks like T lock and whatnot). And I have 1/8 stars from before. I wanted a 1/8 leveling system but Canadian stores are retarded like that sometimes especially in Quebec state (damn French entrepreneurial mentality sometimes but you gotta love them otherwise). How did you choose grout width? So far I understand 1/16 can lead to noticeable lipage but looks good if done well, 1/8 is a great compromise of the two: easy to set but wide grouts are not as "purteeeh".

Long video but worth watching, even you are not setting tile yourself. Will help ensure that you select the right products or to ensure that your tile guy is using the right products.

@jeffostroff

6 жыл бұрын

Joe, first of all, you should not use plywood on your BBQ grill, and in fact I think building codes require cement backer boards anyway. Cement boards are a better substrate to bond to thin set mortar. Wood has too many complications and you almost have to be an engineer to figure out which bag will work on wood, and wood on a wall, and wood on a wall outside. MAPEI Kerabond is good, so yes remember it is only ANSI 118.1, unmodified and you need that additive to make it polymer modified mortar. Why not use Kerabond T, which is made for heavy stones, or UltraFlex 2 which is already polymer modified, just make sure they can be used on a wall. I would also call guys at Schluter, I call them many times with questions and they can tell you if their Allset would be useful, since it can handle ANSI 118.15T, which means low sag which you need for these heavy tiles. Also since you are outside, remember TCNA standards require 95% coverage on tiles, so make sure you back butter each tile 100% prior to setting them into the troweled thin set on the walls. Call Schluter and MAPEI guys and ask them too. These stones are heavy so you need a good mortar that can bond and hold that weight as most thin set mortars are made for lighter tiles. Who makes the stone, do you have a product number?

Dear Jeff, I really appreciate for your time and giving me all these information. here is the information of the stones that I am using. They are not heavy and does not require grout since they sit on top of each other and there is no gap. www.islandstone.com/product/rustic-ii/temple-lava-233 Color: Temple Lava Size: 4 3/4" x 15 1/2" ( 3/8" to 7/8" thick ) Code: cr5bl www.islandstone.com/mediafiles/product_gallery_photos/Rustic-II-Temple-Lava-313.jpg Before I was thinking to use Loctite PL Premium FAST GRAB Construction Adhesive instead of mortar.

I know this is an older video, but almost everyone is using modified thinsets (including Schluter all-set). All of them (including Schluter) have curing agents that allow curing without the presence of air.

Question I’m tiling over drywall and I’m using ECO Grip Primer on the wall, can I use a modified thin set?

Thanks for a great video. Would modified thinset mortar technicality not be good for tiling any tile over a waterproof wall such as Kerdi, Red guard, etc since the mortar would be trapped between 2 impervious surfaces?

Phil, it's confusing about whhich manufacturer wants what. Kerdi wants you to use unmodified thinset to tile onto their products. But redgaurd says use modified thinset. I don't know why, I'm simply not a chemical engineer, but it boggles the mind. I just go with what they say. My favorite one to use is Schluter's Allset because it can be used on anything, and as I showed, it supports all the specs of a modified and unmodified thinset.

awesome thanks!

You’re the greatest! Can you tell me what the name the book is please? Thanks for this video.

Great Video. I have been looking everywhere for information on what type of thin set to use over the USG durock waterproof fabric membrane (I bought the USG Durock shower system on Amazon which they now don't manufacter anymore). I used unmodified thinset (Ditra Set-$50 bag online) to apply the membrane fabric onto PermaBase cement board. Difficult to find any unmodified thin set at Lowes/Home Depot now a days. Ready to set the tile, but now I am not sure if I need to use unmodified or modified thin set to apply my 12 x 12 porcelain tiles onto the membrane. My husband doesn't think it matters and would prefer not to spend the $$ to get more Ditra-Set online and just buy less expensive modified thin set locally. After listening to your video it seems un-modified would be better because of the impervious membrane and drying time for unmodified would need 1 month. It seems that Ditra-Set is not needed to apply the tile but I cannot even find Kerabond or Laticrete anywhere near me without having it shipped which costs a fortune. Any recommendations appreciated. Thanks.

You need to find local flooring supply companies that supply to tile companies, they usually have it that is where I buy my All set from. It helps top go to schluters web site and search for where to buy it.

its any tile with an edge greater than or equal to 15" for LFT

Hi, great video. I am planning to use the DUROCK cement board cement backer board for my shower walls and I am going to roll it with AquaDefense membrane. Which mortar should I use? Thanks

Kendy, the instructions for MAPEI AquaDefense state that: "For tile and stone installations, use MAPEI polymer-modified or epoxy mortars. " They also state if your using large heavy tiles or large format tiles, you have to let the AquaDefense cure overnight before tiling.

Now does the same information apply to cement board too? As far as modified and unmodified goes.

@@99leeray No, with cement boards, you can use mortar directly on them, BUT... you are supposed to waterproof the cement boards first anyway, with products like Red Guard. Red Gaurd instructions tell you to use a modified thin set that conforms to A118.4 or A118.5 both standards I detailed in this video. But other companies like Schluter, if you had waterproofed the cement board with Kerdi membrane, they require UN-modified thin set. So you always should read the directions of the manufacturer of whatever the morter will be troweled onto for guidance as to whether you should use un-modified or modified thinset. If you use Schlueter's Allset mortar, as I often do and show it in this video, it takes the guess work out of the equation.

Can I use unmodified, thin, set to do my taping and corners over hardy backer?
