I recently had to do some work to my shower drain, and in the process had to dig out some of the grout. No problem, I thought, ill just regrout when Im done. I went to HD, bought some pre-mixed grout, and had at it. Cleaned, dried, and basically followed the directions. After the appropriate drying time, I used the shower again, and the grout ended up all mushy. I cleaned out the grout again, re-grouted, and let dry even longer. The grout was hard and dry, and I used the shower again. Same results. Mushy grout. Is there a specific grout that I should be usung for these very wet conditions? I looked at all the different grouts, and none said anything about being specifically for showers or baths.
Thanks in advance,
Drew
