Q:Can this be used under vinyl flooring
by|Mar 29, 2023
3 Answers
Answer This Question

A:  Hello Keith. No, FloorMuffler UltaSeal is not designed for vinyl flooring. However, you can find two FloorMuffler underlayments on TheHomeDepot.com that are approved for use with vinyl flooring. Please search for FloorMuffler Encore, which is designed for vinyl plank/tile flooring with or without an attached pad. FloorMuffler LVT is designed for vinyl plank/tile flooring without an attached pad. Both products can be purchased on the Home Depot website.

                  This underlayment was very easy to install. Cutting to size was fast and taping together each roll was not too challenging. Having 2 people is definitely recommended when working with this product.

                  Went down very easy. I was a bit dissapointed in the adhesive which held the white backing down. It seemed not as tacky. Overall I was very happy with the ease of installation. The rolls were easy to handle and the system for connecting them together was clever. Once I got the hang of it the floor went down pretty fast.

                  Of the couple of underlayments i've used this is my favourite so far. The other underlayment was cheaper but had no longitudinal stiffness so it was hard to lay. This just lay itself out straight and is nice to walk on.

                  Easy to install, but you need to work carefully and slowly to line-up the seams. As it wants to roll-up, use pieces of your new floor to hold it down temporarily. This product is very expensive but I bought it as I'm trying to do a great job on a floor that should last decades.

                  This is an excellent product. We used it in all our bedrooms underneath the hardwood floors we installed. It really softens the feel under your feet and dampens the sound. It's easy to install.
