top notch water proof underlayment

Would Recommend

Stainmaster waterproof flooring underlayment is to be used under floating laminate and engineered hardwood flooring. this provides a cushion and helps keep the "hollow" sound down that you get when walking on some flooring to a minimum. This is also waterproof which is great for pets and kids. this also eliminates the need to add vapor barrier along with the underlayment and also has antimicrobial treatment to inhibit the growth of mold and mildew. I used this in the entry way where it gets a l...

Very good, but...

It's a good product, unfortunately, like far too many things these days, it's overpriced for the coverage. That said, for floor products that already come with an under layment already attached, best to go to old school practices.

Perfect for uneven concrete

Would Recommend

We are working on rehabbing an old garage sized room and planned on putting laminate in under the washer and dryer. This underlayment is perfect. I like that it is waterproof and it is thick enough to smooth out the unevenness of the bare concrete. It feels like it is made of good quality foam and I expect it to last for several years. Installing is simple - It has a strip of tape on it to join sections and they recommend using duct tape for the edges. Very satisfied with this product.

Waterproof Laminate for Flooring

This waterproofing is wonderful. Very easy to apply and use. Instructions were included and easy to follow. The glue and flooring needed to complete the project were not included but easy to attain. This is an awesome product to keep flooring under tile, laminate etc. from getting wet. I really appreciate this product.

Nice versatile product

Would Recommend

I am actually using this on the concrete floor of my basement underneath 1/2" thick interlocking foam carpet squares that I didn't want to put directly on the concrete. With the foam being about 1/8" thick, it feels like a quality product to me. I like that it will provide a nice vapor barrier to keep any moisture below the flooring. The air channels created by the grid on the bottom surface will help any moisture to dissipate more quickly and give less of a chance for mold or mildew to start gr...

Does the job with out a hassle

Would Recommend

This stuff was easy to work with and felt thick enough. Its got tape on it so you don't need to buy tape to seam them together. Make sure you follow the instructions as I first laid it out wrong way. Had the tape facing the wrong way.

Waterproof Laminate underlayment 3x25ft

This is really easy to install foam underlayment.. I like that it is waterproof which is a large help when you have life accidents that happen, even when you use water proof laminate its good peace of mind that your double covered, It defiantly makes floors warmer and less noise when waling on the flooring. the pre set tape insured that it was overlapped at the appropriate spot for perfect coverage. Comes with limited lifetime warranty and also has anti microbial to help prevent mold growth woul...

Makes the floor much nicer!!

Would Recommend

This underlayment is for under laminate hard wood flooring. It is moisture resistant and it is waterproof. So it’s good for trying to keep your laminate flooring dry. It also gives a good cushioning to the finished floor once all done. I am tempted to say this would help somewhat for sound proofing as well. It was fairly easy to put down. It comes in 3 foot by 25 foot rolls, so it lays out pretty quickly. This foam isn’t overly thick but it certainly made a big change in how the floor fel...
