Video shows water being sprayed on inside of shower wall flowing through Bostik grout to outside of shower – in less than 20 seconds!
In renovating our master bath we were persuaded by the tile store’s salesperson to use Bostik’s NeverSeal Urethane grout. While being an order of magnitude more expensive than traditional grout; the benefits of not having to seal, stain resistance, and resistance to cracking sounded like a good tradeoff. We specifically used 2.5 containers Bostik 9-lbs Delorean Gray Urethane Premixed Grout with 3”x6” polished carrera marble over Hardibacker backer board that was sealed with RedGuard waterproofing and crack membrane.
The general contractor had limited experience with the product but was willing to try it at our request. He indicated that it was more difficult to install due it “chunky/sandy” consistency and was more difficult to remove the haze on the surface of the tile.
3-4 months after installation we noticed water spots in the ceiling below the master bath. After exhaustive investigation by the general contractor (and a bath/tile expert I separately hire to investigate) was determined that: 1) the grout was not resisting water, 2) allowing it pool between the grout and RedGuard, then 3) flow to the lowest point – the ceiling below on one side and corner where floor and shower wall meet on the other. Attempts to seal the grout provided a short term solution, however the problem returns within 1-2 months. Additionally, the grout is heavily stained in some areas that repeated cleanings can not remove.
Numerous attempts to contact Bostick have not responded to.
The product appears to have some major failings, at least for my installation, and Bostick has been unresponsive in addressing. The contractor will be starting tear out of the tile and grout and replacement with a tradition grout shortly. It has been a very trying and expensive experience with NeverSeal Urethane grout. I cannot recommend this product or the company’s support.
