Smooth Foundation for My Basement Laundry Room
(2025-04) Underlayment Transforming my basement laundry area with thin, waterproof vinyl flooring seemed like the perfect upgrade—sleek, easy to clean, and a safeguard against dirt clinging to fallen laundry. But I quickly ran into an unexpected issue: the flooring was so thin that even minor imperfections in the concrete messed with the locking seams. A solid underlayment became a must. This particular underlayment checked all the right boxes. It’s firm enough to prevent buckling under weight...
Good underlayment with moisture barrier
Flooring in a basement on top of a poured concrete slab can be a gamble. The floor is hard so you want something with a little cushion. Moisture can be an issue so you need a good vapor barrier, and if water floods in from outside or above, you need a way for it to dry out. It's also helpful if the material is not organic to prevent mold or rotting from being an issue. So I was looking at products to put under a laminate plank product and this checked all the right boxes. I like that it has ...
Easy, convient, do it yourslef
I was expecting a big roll and was happily surprised that it's individual pieces making it easier to work with and it is thicker than I imaginged 1.5mm would be. Each piece is grid marked for easy cutting and shows you which side goes up for proper installation. We are redoing a room in the house and are putting in vinyl flooring so I selected this product knowing we would need it for the floor and the amount provided was more than the space we need it for so it worked out great! It being in pl...
Great Underlayment
I highly recommend this underlayment. It is easy to use, and cost effective. Coverage is100 square feet (25' x 4'). The fan-fold format of this makes it easy to layout a room quickly. Just unfold the desired length and cut to length, and if needed cut along door frames etc. The grid pattern on the top helps with cutting and layout. This underlayment also adds an additional layer of thermal insulation to keep floors warmer in cold weather. There is also a tape strip along one edge to help with se...
Great product - easy to use and work with!
Very happy with this product! I found it very easy to maneuver and install verses the unwieldy large rolls we were stuck with before. The grid lines are convenient when you need to cut and/or align with the adjoining piece and it comes with ready to seam tape pre-attached. This is a 2 in1 product that provides both a sound and vapor barrier -- as well as some extra (minimal) cushioning that helps even out any imperfections if your floor is not 100% smooth/level. I liked that this is an easy st...
Easy to use, maybe a little thin?
I have always used a similar product installing vinyl flooring, so my comments will be in comparison. All underlayment of this type is designed to provide dampening to the flooring to soften the sound of walking on the floor. Most of these products provide a moisture barrier as well. This product checks both boxes, but I feel it is a little thinner than I like. The other brand has a 3 millimeter thickness, this product is half that at 1.5 millimeters. Is thicker actually better? I'm not sure, bu...
A Nice product !
I got this underlayment to put in a new luxury vinyl plank floor on an old wood floor ! I didn’t have the time to try and restore old wood floor , so I decided I go the route of Luxury Vinyl Plank. It was very easy to install. After installing the second row , it has foldable tape to join sections together. I got two packages and only used 2/3 of each package. I think you would like it too ! I would recommend this product to all !
Low profile and works.
This was used to cover my ugly vinyl floor near the back door. Turned out better than i thought. So my first impression was not very good, thin and looks like the flat packing foam. While installing this underlayment my mind was changed. This is easy to cut to size, maneuver in tight spots and helps keep the noise down. This is not to stop the sounds of walking in boots, but it does muffle it a little. Moving the vinyl over the top was a cinch but it can still tear just cover hole with duct tape...
4 Questions
Why can't it be used under laminate? It's practically identical to the products that are marketed and sold for use under laminate.
