I just did some wall tiling in bathroom, really regretted to use Davco 1.5KG white sanitized colourgrout - it's very gritty, looks ugly and feels rough. Unfortunately I bought it without checking the product reviews beforehand (There had been some negative reviews). I used Davco grey colour one a year ago, it was good. Now I want to get it fixed. Do I have other options other than removing the grout completely and re-grout using different product? Thanks for help.
