I'm doing some work in a bathroom and not having good luck with the grout. Is sanded grout more effective than unsanded grout (especially in joints about 1/2 inch). Common sense tells me "yes", but what do I know. Might be "another" reason why the grout I put down isn't drying properly (it's been since Nov'98 and still grout is damp). Thanks and would appreciate more thoughts on this matter.
