I stuck it to my plywood subfloor with double sided carpet tape (long process) and ultimately switched to staples. The staples don’t dent it as it is firm but not hard underlayment. It makes the floor quieter, but my main reason was for floor thickness as I wanted the thinner vinyl to be closer in thickness to my already installed bathroom and laundry room tiles. It is really working great so far. FAST delivery and goes down pretty easily. Does require some vacuuming as cutting causes debris that interferes with tile installation. It is a really great product. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Good Product *by I***S on Reviewed in the United States on January 4, 2013* This was the easiest underlayment I have ever used. Rolls out well, cuts easily and was done in no time. Doesn't have bad curl everywhere like some of the other brands I have tried, though the inner ends do need a day or so to straighten out. I would use again but make sure it is securely attached to the subfloor. I had a few areas where it wasn't, and I didn't think it would be a big deal, but now the tiles are moving slightly and the grout is cracking in that exact spot. Everywhere else is fine, so I suspect its my fault. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Great! (except for the ends) *by M***N on Reviewed in the United States on July 12, 2013* This is seriously good stuff. Pretty easy to work with, except for the end of the roll - which predictably wants to curl up. You'll need something heavy to flatten those pieces out - say, big long boxes of hardwood. Otherwise, the sound and temperature absorption have been fantastic (ranch style house, concrete slab, engineered hardwood). --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/6346681-qep-72003q-1-4-inch-6mm-4-foot-x-25](https://www.desertcart.us/products/6346681-qep-72003q-1-4-inch-6mm-4-foot-x-25) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
