Got an order of 9 rolls of 8mm rubber rolls for my fitness studio. I was going to get thicker stuff for the weights section but with help from my more experienced rubber floor installer guy, decided the 15 foot rolls would fit the layout with zero end seams to worry about curling, which seemed like a wise decision since I'm not a high volume heavy lifting kind of studio anyway. I got the blue and gray fleck color, since tips I'd read said I'd regret all black as it shows dirt more. Seems about right now that I have it in.The rolls came stacked in a pyramid on a big pallet which would not fit through my door, and the delivery guy did not have a dolly, so I had to unwrap the pallet and pick each roll up and bring it in. They're heavy. You could easily hurt yourself either picking them up or, in my case, it's just dumb luck that when I unwrapped the pallet I didn't get hurt or damage anything, because I cut the plastic wrap and the pyramid of rolls collapsed and they fell down and rolled a bit.I hired a guy to install it for about a thousand dollars. I knew that it wasn't as simple as some people were saying (by this point I'd done so much DIY in the space that I'd learned that nothing is ever as simple as you think it's going to be) and I knew that I didn't want to deal with it. He had the experience dealing with this stuff, and knew how to lay them out and cut them to fit and glue them down and weight them with bricks and had it all done in a fraction of the time it would have taken me to even decide on which YouTube how-to video I was going to trust.He cut and laid out the rough plan, including adequate amounts of overage to allow for any shrinkage. He let it acclimate to the space for 24hrs, then cut it to fit to the wall and used Henry 640 VinylLock to glue it down to the hardwood and plywood floors. He trowelled on the adhesive, said it's very thick and you have to push it really hard to work with it. The end result seems to be great.I don't know how this stuff was cheaper than everywhere else and also had free shipping, but it really helped me stay within my budget, and it ended up looking pretty good. I may update the review after some time and actual foot traffic.Overall a good experience and product so far.
