It's funny
but years ago, before Dick went to Indonesia or Mexico and I first got a K7, I posted about sealing the grout. I don't know if anyone remembers a unique guy by the name of Jason, but he thought that I had went around with a model airplane brush individually sealing each grout line. Dick put the idea down as he didn't want customers asking for them to seal the grout. In the final analysis though the factory in Sacramento was in the fog belt in the winter months so that his secret soup, the glue holding the tile on, nor the grout was never properly cured before the customer got them. Thus the idea of making the customer do long slow cook curing before bringing the temp up high or the tiles would start popping off. In that case I think one needed to get everything cured good before sealing the grout, so as not to seal moisture in an exacerbate the problem.
