I've noticed ventilation makes a huge difference too. Had a tenant once who struggled with that rubbery smell—got them to crack open windows regularly and run a fan. Cleared things up pretty quick... cheaper than buying new underlayment anyway, haha.

Good call on ventilation. Honestly, people underestimate how much proper airflow impacts indoor air quality. When I first moved into my place, I had a similar issue—not exactly rubbery, but more of a chemical odor from the flooring adhesive. I initially thought I'd have to rip everything out and start over, but after doing some research, it turned out that VOCs (volatile organic compounds) from adhesives and underlayments can linger if the space isn't ventilated properly.
I ended up installing a couple of exhaust fans and making sure windows stayed cracked open whenever possible. Within a week or two, the smell was practically gone. Definitely cheaper and less hassle than replacing the underlayment entirely. So yeah, ventilation is key—it's not just about comfort, it's about keeping your indoor environment healthy too. Glad you found a simple solution that worked!
Definitely agree ventilation makes a big difference. Had a similar problem after putting down some vinyl plank flooring—it wasn't rubbery, more like a weird plastic-y smell. I figured it'd fade on its own but after two weeks, it was still lingering. Here's what worked for me:
- Ran a box fan in the window for a few days to pull air out (not just circulate it around).
- Added some charcoal air purifying bags around the room. Honestly wasn't sure they'd do much, but they seemed to help.
- Also noticed that warmer temperatures seemed to make the smell stronger, so I kept the room cooler than usual.
Within about 10 days, it was noticeably better, and after three weeks the smell was pretty much gone. Glad I didn't panic and rip everything out—I was close to doing that, lol.
One thing I'd add though: choosing low-VOC adhesives and underlayments upfront can save a lot of hassle later. Learned that lesson for next time.
Interesting you mention temperature affecting the smell—I noticed something similar when we redid our basement flooring. We went with a cork underlayment because I'd heard it was good for insulation and noise reduction, but honestly, I didn't even think about VOCs or smells at the time. Luckily, we didn't have much odor issue, but now I'm wondering if cork naturally has lower VOCs compared to other materials?
Also curious if anyone's had experience with cork underlayment long-term. Ours has been great so far (about a year in), but I'm wondering how it holds up over several years—does it compress or lose its insulating properties eventually? Would hate to have to redo everything again down the line...
We've had cork underlayment upstairs for about 6 years now, and honestly, it's held up surprisingly well. No noticeable compression or loss of insulation yet, and it's definitely quieter than the foam stuff we had before. Cork naturally has fewer VOCs since it's a renewable, natural material—way better than synthetic options. I'd say you made a solid choice, and I wouldn't stress too much about redoing it anytime soon... ours still feels pretty much like new.
