            Can this caulk be used for Carrara marble backsplash and counter joints as well as on the joints between Carrara marble shower walls and/or benches? Silicone does not appear to be a good option as it permanently stains the stone according to my research.

                  I got the Custom Building products polyblend caulk in Snow White . It outperforms other caulks and it easy to work with. Love it

                  Color match is perfect with the actual grout. I use it on the sides, tops and bottoms. I've used Custom Building Products grout and caulk for many, many years. Really good stuff.

                  bright white?
                  This chaulk does not match the custom bright white grout. It is noticably darker than the grout. Both the sanded and unsanded were the same off color and did not match the grout. I would never recommend this product.

                    The product is fine. No problems with it. I did not have any yellow discoloration that others spoke about. I'm using this on my tile backsplash and all the areas are dry areas so maybe that's part of it. But if you use the Customer Building Products bright white grout, as others have said, I think regular bathroom caulk is fine. Not sure why I needed to spend the money on this product. It looks good, no problems, but it's still brighter than the grout that seemed to soften in color. You can see from the photo. I used an arctic white tile from Daltile here. If you use other grout colors from CBP than maybe it would be best to used the color matching caulk, but for bright white I don't know if its necessary.

                      Use standard white bath caulk to match Custom Building Products "bright white" grout. Do NOT use Custom Building Products "Bright White" Caulk to match their "Bright White" grout. Like Napasteph's review, I experienced shrinkage. Worse, the Custom Building Products Bright White caulk dryed to a yellow color that looked old and ugly. I covered all of this caulk with a standard 100% silicone bath caulk to get the color back to white. I have used Custom Building Products caulk to match other grout colors with great success and satisfaction. But for a bright white, standard caulk costs 60% as much, and looks 200% better.

                        I used this Linen caulk in my shower to go with my linen grout (which came out much brighter than advertised) and it worked well. I used it for 1/8" to a 1/4" gaps. It is a siliconized caulk so it can get messy, I recommend wearing latex or nitrile gloves. There was one air-bubble in the tube which was annoying and of note, you do no have to poke a seal inside the tube to get the caulk flowing, just cut the tip and you are set.
