Remain Flexible;

Each and Every worker will (with conscience observance) most certainly end-up changing their approach if they go back to see the cracking a few years later, no doubt. Sure, this needs quarterly bleaching (maybe) but because you're  alleviating that ugly black line that occurs while cracking then seperating where liquid enters.  Over time will serperate and cause further damage.

So knowing why, it's simply put this way. The structual part of most walls are framed and stood with wood (my specialty). Expanding and contracting almost daily where as that cemention tile or tub adhered too it, (once dried of course) wont be moving, period. Now where they meet WILL crack and powder and make a mess. But if that particular surface can be allowed too FLEX or go with the flow so to speak. Like a chualking, that once completely dry WILL remain moveable when neccessary and alleviate the bogus black line. Every blue moon You just might need to deep clean like anything else.
