Customer Questions & Answers

Can I use this product to fix cracks in ceramic tile floor?

Asked by: Mason
If you have cracked tiles then your substrate has too much deflection. In other words, your subfloor is moving too much. It is possible that this product will help, but I would check the subfloor and see if it can be strengthened.

is this product recomended for use on wood subfloor to hardie backer?

Asked by: Anonymous
Late answer, but I'm about to do just this with 1/4" Hardi Backer board. As this products exceeds ANSI A118.1 and A118.4 (specified by Hardi Backer for 1/4" on floors), I would say: "yes". I will update post after using.

Does this come in different colors?

Is there an additive you can add to grout to make it more flexible?
Asked by: Anonymous
Yes. White and grey. The color is somewhat irrelevant though, unless your doing it wrong. More flexible? I don't know but if you need flexible thin set then you have a problem that thin-set will not fix.

Rated 5 out of 5 by from Mixes well. Easy to apply and to use. Excellent bonding strength Flexbond is my go-to mortar for bonding ceramic and porcelain tile. I have used this product to adhere tile to cement as well as to wood subfloors, with extremely good results. The product mixes easily with water and applies smoothly to all floor surfaces using a notched trowel. Only mix what product you can use in an hour to avoid waste. Once cured, Flexbond creates a permanent bond between the tile and the floor. Its important to clean Flexbond off tile surfaces before it cures because after it cures, it's impossible to remove. I value my time, effort and labor, and would not trust any other mortar product. Highly recommended.

Rated 5 out of 5 by from excellent bonding ability I used this to put travertine on top of previous ceramic tile in a large shower enclosure. I called the co. and they said to rough of the ceramic tile with a course circular sander/grinder. It has been over ten years not a single cracked or lifted tile. Incredible bonding, excellent for vertical surfaces.

Rated 4 out of 5 by from Bast thin set I have used If you are going to be considered a professional and expect to get paid to do something then you should use the best product available for the job. Expensive, but worth it in my opinion. This thin-set has never failed me.
