I pitched mine in the garage on top of a blue nylon tarp ( i feared the acids in the concrete). i used duct tape and string for anchors - did not want to leave sticky duct tape adhesive on my webbing tie outs. Then I applied the sealer on the inside - presumably where it would be protected and last longer. Two days later I took it outside and pitched it in the (dry) yard on a sunny day and let it warm/sit for a couple of hours. Then I set up inside the garage another two days.

Then I used it a couple of times and sold it.
