I didn't off gas them outside or anything like that since it would've been impractical unrolling them outside, leaving them out, then lugging them inside the garage. I did however lay them flat in the gym for I believe 48 hours before installation. There was some smell, but it wasn't overwhelming at all for me. The odor that is there goes away pretty quickly as I recall. It might help to leave your garage door open during the day for a few days after installation to quicken the process.
Thanks for the heads up. I just reached out to my contact at that company to fix the issue. Stay tuned -- I'll let you know when I hear back. I appreciate the support!
Alright, so my contact told me that (currently) the price of these 1/2" rubber rolls is one of their "Every Day Low Price!" items, meaning there's already a discount built into it. Meaning that no coupon codes can be added to further lower the price. If you still decide to buy, I'd greatly appreciate if you do so through my link -- shrsl.com/48vh6 -- as it helps make my reviews, articles, and videos possible!
UPDATE: Ok -- I learned of another solution. You can instead buy the 1/2" option from this other page: shrsl.com/4gqfs -- It's the exact same product as the 1/2" Mega Rubber Rolls. My KING coupon code for 30% off will work with this one. And when the code is used, it ends up saving you a little bit extra compared to the "Every Day Low Price!" price of the 1/2" Mega Rubber Rolls. Hope that helps.
