I like the idea of the modified polyethers. But I don't think the membrane suppliers will warranty a job using modified sylane instead of thinset. There doesn't seem to be enough data or long-term testing. I'd love to know if someone has done any long-term tests. Isaac, you mentioned a test shower pan in your video, but I am not sure I've seen the results. Are you still running the test you mentioned in the background? Noble EXT can be used as an adhesive for sheet membrane, but I don't know if it is a modified silane. It looks to be a VCT adhesive. Can anyone confirm? I also haven't found any modified silane available by the gallon bucket. Everything seems to be from a tube. Being able to trowel on a thin layer of modified silane as you would then set could be useful. That is, if it will last decades once cured.

Thanks for doing ALL your demos. So informative!

Great tip on the Grime wipes, and amazing how little sealant mess ya made (phone notwithstanding). Thx!

Excellent Video and test! Thank you Issac - This is very Awesome to watch and to know what works and what doesn't!

Schluter themselves say that Kerdi fix is not a waterproof sealant if you go to their workshops and their website they are very clear that they will not warrantee it if used in a manner as you are demonstrating...so not sure what you are trying to prove here. You are 100% correct in saying that In Europe they do NOT allow the use of thinset to seal the membranes. With Schluter, they use Kerdi Col (NOT KERDIFIX) in Europe which works very well, however it is hard to get in the USA. I have had it direct shipped from the UK to the USA A better experiment would be to use Kerdi Col with the Kerdi Membrane since these two products are engineered to work together, rather than using something that Schluter ALREADY KNOWS, WILL NOT WORK. In either case it was an interesting test

Dude, the more I watch your videos the more I appreciate you. I'm an old 64 year old guy who does work on bathrooms etc around houses I've owned. Being old school, I look at things differently. I mean they take this styrofoam type Kerdi board made of nothing but that and a membrane, so it's light and an attractive solution over the mess of concrete boards. Then they make one reinforce the shit out of it with all this thinset which is time consuming and messy work beyond what it first appears. So this sealant is a gem I think, the best of both worlds. Thanks very much for the great quality information you produce.

Really cool test. In engineering school we used blue grid line paper for leak testing of models because a single drop of water will blot the blue lines and you can trace where the leak came from with visual clues of the severity. I use that trick to this day

Whenever I have a question like "I wonder if Rapidset sealant would work...", you already have a full video testing it. 😆 Thanks!

Brilliant. Could not agree more!!!

What a time saver. Not only not having to mix mortar, clean up what’s left and waiting for it to cure but hardy any waste.

Should do a test with the sheet membrane wet/damp initially. Maybe these could be used for a temporary repair on a pan to get by before a full remodel or something similar

When I did my last bathroom I used silicon. Works under water beautifully. Super strong grip and cures even when sealed in.

Thanks for making these videos and documenting your hunt for the perfect waterproofing. I put my money down on the black sealant the second i saw the viscosity of it! It´s the most similar to the one i use in Sweden. I use Kiilto keraseal and Kiilto membrane (Finnish brand) and have done so for the past 12 years. have never got a callback because of leaks.

Why does this guy not have a million subscribers yet??????? His matter of fact, here is what it is approach deserves more than his current 229k subscribers. All of you 99% watchers but not yet subscribed, need to hook this guy up. At least share his videos on whatever social media platform you use.

One of the things to consider in testing is mechanical flexing. Sure the leak tests are great and important but the real test is to see if it can withstand normal mechanical load flexing and over time. No simulation is perfect but the tests should try to evaluate it if possible. E.g. some sealants cure hard but will leak as it cracks with load...

Moisture curing compounds are super cool. Moisture curing paint started showing up for commercial work is far as i saw was in the mid 90's. Super expensive but super tough and heavy/dense. And if it rained on it that same day, no problem. Or damp wood, no problem

Thanks: great honest advice.

❤. Well done Isaac! Can you share the details on the Rapid Set sealant you used? I wasn't surprised that the private label sealant didn't leak. The less viscosity the more complete penetration of the fleece. The extreme viscosity of the K Fix doesn't allow it seal the fleece fiber so water can literally wick through the fleece beneath the sealant and reach the paper strip. Has anyone released or discussed the future release of non thinset sealant to apply membrane?

Thanks for honest testing

Where I saw a potential issue was with the Schluter "Kerdi-Kers", which tended to contract as the RapidSet cured, causing them to pucker creating a small ridge or high spot. I didn't have that problem with bands at the wall-floor junction or over the curb with Kerdi Membrane.

I believe the flofx drain installation instructions say to put a bead of sealant around the drain and sheet membrane in addition to thinset. Now I know why.

Hello Isaac! Thank you for doing this great test! I know you tested these sealants replacing thinset under membranes, but what would you expand your thoughts now maybe using these 'working' sealants under shower tiles themselves, more so best with mosaics, instead of thinset under tiles? I'm doing a rectangular shower now with a KBRS manufactured hard-foam (harder than Schluter) pre-sloped shower base with 4" sealed lip boarders using Goboard. If sealants are so waterproof and adhesively effective, maybe time to dump thinset all together under mosaic shower base tiles??? Or would you still stay with a newer thinset under shower base tiles like the Laticrete MULTIMAX you seem to enjoy now? Thank you in advance if you happen to read this!

I did a mock-up of a mortar bed in a cardboard box. Let that dry and applied hydroban sheet membrane, hydroban corners and ban using mutimax lite. Let that dry overnight.

Thanks Brad and I am glad you are experimenting yourself! That is great info that you can share with your clients to give them confidence. I have only gone to 14 day on a glass box test, but I believe your results. One flaw in the cardboard experiment is that is is breathable so the moisture escaping evaporates before it wicks into the cardboard. A better test is a wood or drywall box to better simulate a shower build.

Do you think it will have the same affect on the front side of the sheet membrane? I'm thinking for screw holes, corners, etc. The sealant may work great on the back but not the front? Your video tests are amazing!

Thanks, I'm now using Rapid Set. I was thinking that perhaps the Kerdi-fix samples got water infiltration because it took longer to set up. In that case the water would have come in at the start of the submergence, whereas quicker setup products would have prevented the initial infiltration. A better approach might have been to allow the samples to all setup over maybe 24 hours and then submerge them. Perhaps they would all have come out dry?!?!?!?!

Wonderful Video, great work! *****Stars

That's a ver helpful video👍

Have you tested Laticrete sealant? I've been wondering the same thing, given the limitations of thin set. I've wondered if something like Hydroban liquid membrane might actually be a better solution between the foam tray and the membrane. I know it would be waterproof, that's not at issue as long as it will cure. The problem is that I don't know how much the rigidity of the thin set might be part of the structure of the system especially around the drain given how thin the tray is right there. Have you considered that aspect?

Back in the day (I’m talking 80’s/90’s/early 2000’s) it would cost roughly $150 for pan liner sand cement and lath for a shower. Prices stayed relatively stable. Now with all of these water proofing products out there is gone completely nuts. For a shower with a bench and a niche’ were talking $1484 for Schluter products not including thinset or kerdi fix, which apparently will fail anyway. (Thanks for that btw) In my 40 years of being in this buisness I’ve only seen showers fail for a few reasons. Most of which had to due with improper installation of the pan. (liner/drain/no pre-slope/nails below that dam/ or pan liner cut below that dam) If the walls are done correctly, paper backed lath, then there was never any water damage. The other reason shower fail is idiots who should not be doing tile. Then you’ve got builder grade tile installs over green board or drywall. Those usually last 10-30 years depending on amount of use. I’m not even going to touch on hot mops. I’ve never seen a shower fail above the dam. Water doesn’t sit on the walls for more then a few minutes. When originally released, untreated Hardi backer was displayed in a sealed jar of water. So in my experience all of this ridiculously price shower prep materials are just a way for coporations to stick their hands in your pockets. Your video here is proof of that. Keep up the good work.

Isaac, i would be curious to know if you think Rapidset is strong enough to be used instead of thinset to bond Kerdi fabric to wallboard? Do you think it could hond the Kerdi loaded up with thinset and LFT without separating?

I have good success with pretty much all RapidSet products, they’re pretty good, imo, and not a bad price

What about using a latex modifier exclusively instead of water when making your thinset. I know it’s expensive but could be the answer, assuming you haven’t tried that already. My guess is that if you looked at the applied thinset between two pieces of membrane under a microscope you would see tiny little channels where water is drawn along through the fibres of the membrane. When using a sealant maybe the fibres become completely saturated with the sealant. As another KZreadr predicted, the thinner black sealant would be the most successful due to its viscosity.

I used the Hydroban system on my shower mainly because of all the failure videos of Schluter. I understand that those failures were because of user error for the most part but as a DIY'er I'm not using a product that has ZERO room for error....for example , you need 2" overlap , if you miss measure and have a spot that's 1 3/4" LEAK!!! But that's what you get when you use non waterproof products, such as thinset, to waterproof your shower.

Nice video. Still confused on one thing. What’s the best sealant to use to attach the membrane onto cement board? Just use thin-set and the video you made is for membrane to membrane attachment only? Please advise. Thanks

Interesting test. Have you tried testing the Kerdi fix after it was dry?

I was thinking the same thing. I’m a tile setter in the Northeast and Wedi is an extremely popular system around here (I install a hybrid system, wedi board on the walls where it offers waterproofing but also bomber adhesion and then a mud pan and sheet membrane on the floor with waterproofing band around the floor to wall joint). I’ve played around with using wedi sealant under the corner pieces and band, and have found it to be extremely waterproof BUT hard to spread given its thickness and, more importantly, suffering from poor adhesion to the band and, over time, even to the cement coating on the wedi board. The adhesion problem is one that im not sure would rear its head too often in real world circumstances, but it worries me nonetheless. In my mind thats the greatest flaw with wedi as a complete system. It’d be very interesting to test hydroban sealant against it for waterproofing the band, or even a lap sealant like Geocell.

Great. I know your technique is evolving, but given what you know today, would you use the sealant or 8+9 to seal the joints. The sealant is certainly less expensive.

I'd love to see the same test with Wedi 620 sealant. Also, what about Schonox AB & iFix? It's an incredible product.

iv been doing tile for about 25 years, you wrapped a lot of things up with the simple saying, follow the money.
