Questions & Answers

Can you add sand to this?

Can you add sand to this?
Asked by: Akahoshisenjo
This product is already almost entirely sand... Unless you want to fill a sandbox, I don't think you'll be needing more sand.

Can this be used with Schluter Kerdi waterproofing membrane?

They reccomend using an unmodified thin set mortar for the installation of their waterproof membrane.
Asked by: Rong
you loose Schluter warranty installing it with modified - only when installing glass tiles or installing Ditra over plywood - read on their website or call them directly. Custom non-modified is a .... well, not the best as a non-modified thinset as it ONLY meets required standard, meaning there are better, blended with more Portland cement and less "sandy". IF you can't get a better grade non-mod...might as well go with a good quality modified and throw the warranty out - still works better, but curing time is longer

Can this be used applying tile against a hardibacker board as is without additive?

I already used it against hardibacker and I'm concerned if it will hold up? It seemed to adhere well.
Asked by: Rj
It will for a while. But overtime it will become brittle and break. I would go with one of the 15$ options.

What does 2 set mean on the bag of thin set

Asked by: micki
It is step 2 of tiling. Grout is 3. 1 is prep, like waterproofing and leveling products.

CustomBlend Gray 50 lb. Standard Thinset Mortar is rated 3.0 out of 5 by 37.

I tried to use this to install Kerdi membrane for a shower wall. It simply doesn't smash down properly to get the required coverage. I tried twice! Finally I called Schleuter and they recommended cleaning everything off (another hour!) and using a good thinset. This might work for stacking bricks, in fact it's just like the mortar I've used for stonework. Avoid in shower installations!

If I could give 0 stars, I would. I'm actually angry that HD even caries this product: it is THAT bad. In my opinion, this product almost jeopardized my entire (30k$!!!) renovation. I started using this for the waterproofing of my shower. It was my first time using thinset, so I didn't realize that this product was utter junk! I had to use an unmodified thinset for the schluter product, but this is basically grey sand... very little adhesion- good luck getting it to hold a notch! I shudder to think what would have happened if I'd tried to tile with this stuff. Honestly- if I'd used more than one bag of this (out of the 12 that I ended up using for waterproofing and tiling) I think my entire project would have been ruined. It's garbage.

Rated 1 out of 5 by from Miserable Thinset I wish I can give zero stars but I can't. I used this for a Kerdi Mat installation over wonder board. I normally would never use either products but the homeowner insisted. It failed! I mixed it thick enough to hold a notch and 72 hours later it was still soft under the Kerdi and the unused thinset in the trash was soft as well. All of this was done in 60+ degree weather. I contacted Customs to let them know about the failure 24 hours later because I thought it was unusual for this to happen. The Tech Director promised to call back the next day but never did. I sent numerous emails with pictures showing their failed product from many different angles and also many phone calls to their tech support requesting that they would send out a rep and reimburse the labor and lost materials due to the failure of this product, only to be met with unreturned emails and phone calls. In the end I had to call from a different phone number just to get through to the Tech Director to be told that I would need to ship the 25 pound bag at my expense to their people who will test it to determine if it is faulty. I've been a tile contractor for 20 years and using their products for 30 years, but after this treatment, never again.

It is too sandy and difficult to work with compared to Versabond and other manufacturers' dry-set products. I used it to attach Kerdi membrane over drywall for a custom shower and I had to mix it fairly loose and work fast to get acceptable results. I had previously used Versabond with Kerdi on another shower with MUCH better results, even thought this technically voided Schluter's warranty for the Kerdi installation. My advice is to get something else if it is available, or use Versabond and wait a few extra days for it to cure properly. Home Depot should be embarrassed that this is the only dry-set mortar that they stock.

Applied this thinset to damp Hardiback and porcelain tiles. After three days of curing, the thinset did a poor job bonding. I am able to peel up half of my tiles by hand.

Rated 1 out of 5 by from Awful. Save yourself doing the job twice and get any other option So I used this product for 3 rooms of my house last year. One I have redone, the others are on my to do list. It does not stick well to the tiles or backerboard. I did not use the admix, which it claims "for higher bond strengths". I honestly believe they should rephrase it, "for ANY bond strength use the admix". The best thing I can say about this product, is that due to its weak bond strength, it makes tearing it out very easy. Obviously because you are going to replace it later with a better product. All the rooms I redid using other products have lasted with no problems. So I have a high level of confidence that the problem was using this.
