Here is what I use. Floor grout, sanded or unsanded. It comes in every color under the sun nowadays. Next time you are at the home improvement store, look at the grout colors. An 8lb. of unsanded grout is around $10 dollars or so. It will last you a lifetime. I used to work at a flooring dist. and have way too many bags of the stuff just sitting around. You can custom blend colors and such and it will not discolor over time. Just a thought.
