Rockit's line is now wall free.
About the London waterfront wall...whatever they used for that marble look was either not done properly or was of poor quality (or maybe both). It is cracking all over the wall, not just on the tops where the lamps will be. Those are where the most serious/visible cracking and crumbling is taking place, but it isn't the only area. The odd thing is that it is very thick and cement-like, not like a simple multi-layer latex/paint texture job like I figured. Bob or Teebs, any refreshers on what that top "coat" is? I could clearly see the concrete form in a few places where it was badly cracked and crumbling, and it looks to be about a half inch thick or more.
