Do you find that it is slippery when wet?? Just curious. Great creative ideas. Thanks for sharing.keithw said:Thanks for the comments. I created the cobble effect buy using one of the cobblestone forms from Quikcrete and pressing it onto the wet cement. The deck and the waterfall aren't really painted, it's a Xylene based stain/sealeant from H&C. It bonds right into the cement and is supposed to last for many years.
