  1. Can you use this system in a shower? Is it better to use the grout provantage than the silicone on the inside ? Is there a sealer

    • Hello Janelle. Yes you can use this system in a shower, but when doing so you have to grout the joints as well just to be sure water can’t make its way in there. Most people choose to use mortar over silicone when it comes to showers, but both can be used. I hope that answers your question, if not let me know. Feel free to check our website for some more info at

  2. Hello,

    I am looking to use this system to install some glass blocks. The blocks I have are 3-1/8″ will the 4″ system work?

Let us know what you think.
