About 5 yrs ago I installed peel and stick flooring from Lowe's.
I was super happy with it for a while because it suited my needs at the time and overall, it looked fine. But some pieces started to pull up a bit. Still, most are fine but I want to fix the ones that are pulling up. I'm thinking of two options. One, find a super strong glue to squeeze under the parts that are coming up. Or two, just nail them down. I know the nails won't look great but I nearly never have company so it's just for me. And eventually, I'll probably put down another kind of flooring. If I use nails, what kind should I use? The plywood under flooring is under the peel and stick.
