Just wanted to share what i did to install the Harbor Freight mats and how it turned out so that others can consider it on their own build. Every situation is different but for me this worked out great:
I first laid down the cheap tarp that came with the Intex pool and staggered the mats (rather than a checker pattern) when putting them together "rough" side up like you would normally use them. I didn't tape the seams or anything, just laid the pool right on top. No issues with the mats separating and i can't feel or see where the seams are.
The mats feel amazing and i would absolutely recommend you use them if thats what you are considering.
