I have to replace some dirty and moldy grout between the tiles above the bathtub. But the grout I saw sold at the hardware store said that it has to stay dry for 36 hours. That would be impossible, unless I moved to a hotel for two days. I take two showers a day, and that's the only bathroom I have in my home.
Can you recommend some really fast-drying or quick-drying grout compound? It would just be for this small repair--maybe two square feet of tile that needs to be regrouted.
