I bought polyblend sanded grout from HD made by custom building products. The color of the grout is light smoke. But I can not find the caulk which has the matching color of the grout in HD. I also went to custom building products web site. They don't have the light smoke color caulk either. Where can I buy the matching caulk for this grout? Thanks.
Definitely try a tile store. Not sure where you're at, but in CO there's a company called Capco that has them all. I'd almost be sure there's a store in your area that does too.
