I just finished grouting the wall tile in my new-construction bathroom. I made a point of using a high-quality grout product, and went with Laticrete Permacolor Select (with bright white color packets). Overall, I'm happy with the result, but...
I had difficulty with this product because it cures very fast in the bucket while I apply it. I barely got an hour's worth of application until it became too hard and unusable. I had to use four different 12.5 lb. bags for my project, and I never was able to use all the grout in the bucket, and ended up wasting a lot of it.
The recommended amount of water is 1-1.2 quarts. I used varying amounts in my 4 sessions, and had the same experience each time. I whipped it during the session, but that didn't seem to make much difference (I did not add water ever, except in the original mixing).
So my question is: does Laticrete Permacolor Select grout cure quickly? And is it to be expected that it will only last one hour in the bucket? Is there a trick to keeping it from curing too quickly in the bucket? And is there an equivalent product that lasts longer in the bucket?
