You should've read the directions for the corners. The rounded piece has a matching straight piece that matches and really tightens up the gap at the corner. That's why there are rounded and straight pieces in the corner boxes. They also recommend a masonary blade for cutting the stone.
Ya. There were only a handful of corner pieces per box and I didn’t want to spend a lot more to get more corner pieces. YES! the masonry blade makes a huge difference. Went that route with the angle grinder and damn… huge difference
Been up for almost 2 years without issues. Anything that would have flexed would have shown issues by now. The individual pieces without any grout allow for some flex in my opinion. I have used this on a cinder block pillar outside and it has been holding for 5 years so it has my vote of confidence
It is a snap in full vinyl floating floor from Armstrong. It’s one of their commercial products but is 100 percent waterproof and had texture the way we wanted. It will outlive the house.
