Question from Gigi
I am in the process of selecting grout for porcelain tile that is about 12.6 x 12.6”, Bianco by Ceramica Alberdi via The Tile Shop. It will go in the kitchen, washroom and bathroom and will be installed over Hardibacker. We live over a crawl space and are located in Southern Virginia.
I came across good reviews from relatively new products called StarQuartz Quartz-Lock and Quartz-Lock2 which are urethane, pre-mixed grouts (not cement or epoxy based). This item is sold at GreenBuildingSupply.com, a very good website and brick and mortar store in terms of selling low/non-toxic building products.
Is anyone familiar with either product?
What is your opinion regarding the urethane?
