### ⭐⭐⭐⭐⭐ Quality Product
*by B***P on 5 June 2026*

### ⭐⭐⭐⭐⭐ Size does matter

### ⭐⭐⭐⭐⭐ Easy to install - looks great
*by M***A on 28 June 2026*

I replaced the old cracked expansion strips in my 1970s pool decking with this and it worked GREAT. I just removed the old strips, used some cement filler to fill in the extra space under the new strips and it also helped to sort of "glue" them in. Perfect fit and very easy to install. Used scissors to cut to size and in some cases trim the bottom if necessary for a Perfect fit. This is VERY DIY friendly. I did my whole pool deck in about an hour (15 expansion strips).
