Review: INCREDIBLE Underlay material. - I was about to lay 3/8" Engineered Hardwood (Flooret Silvan) directly over tile, considered the Steico product and wondering whether I would need to pre-fill the grout lines (~1/4" wide by 1mm deep - tile is 20 x 20). Sunco (whose support has been fantastic!) of course gave a, honestly not unexpected reply, that their std recommendation would be filling the grout lines (not unreasonable). But while not endorsing per se, they had knowledge of users who had not and it appeared to be working out. I decided to go for it and have done a double layer (staggered pattern) over a 1/8" lower tile level and single level 1/8" (3mm) over the main area tile as per the image above. I did a test - with the 3mm product (only, no plank yet) I aggressively pounded /stamped / jumped/ beat on it above the grout lines and could NOT get them to telegraph even to the bottom side let alone through to the top! So I may get some disagreement from the community here on pre-filling but with my test and the fact that the engineered wood flooring in itself is quite rigid, I had no qualms about going straight over as-is. Image shows an area that had a tile field that was exactly 1/8" below the main tile level: I believe house originally had carpet section there and previous owners filled with a different tile, but not fully flush up to the other tile. So for this section I put one layer of 3mm in to exactly fill that section to its perimeter with the other tile, then a complete layer of additional 3mm over everything. I was careful to stagger the joints so they did not overlap between first and second Steico layers, nor the planking joints. (for the plank it's easy - fraction over 7" wide which is not a factor of 24 or 36, so it will naturally not create any joints over underlayment seams.) It is SUPER easy to work - cuts easily. I personally found scissors a better tool than a Blade. And I wondered if it would be more work than 'roll' type underlay which I have used previously. Actually I found it to be convenient - one row of 2' panels would accommodate 3 rows of plank and I could just lay as much underlayment as I chose to work my way across room (while juggling furniture around) The result underfoot is that it feels great - indeed quiet and comfortable, and that is also borne out when witnessing from level below. I am absolutely delighted by this product and would not hesitate to recommend this product to anyone.
Review: Great quality, great underlayment, great price - This is an outstanding product. When I installed my new laminate floor, I was a little concerned about the sound, your shoes make on the floor that high-pitched clicking noise, but this underlayment material at only an eighth of an inch thick really made the the laminate flooring sound solid like hardwood. The bonus is, you can stack it to fill edge or corner gaps in floor height. The fibrous content of the material is very easy to cut, and you can feather the edge down to almost nothing creating a very smooth taper. I installed it in no time using a few staples to keep it in place and used flooring tape on the seams. Can’t recommend it highly enough. Oh and by the way, it’s about a third the price of the foam underlayment and I think it’s a higher quality.

## Features

- 3 millimeters (1/8 inch) thickness STEICO Underlayment, 90 square feet package, 15 sheets 2 feet x 3 feet
- Increased living comfort: Enjoy the superior sound control and acoustic improving properties of the natural fibers. US tested and certified after passing the strictest acoustic tests (6” concrete slab without ceiling assembly) which guarantees optimal sound proofing.
- Enhances safety: Natural product made of pure wood fiber material without any glue additives. VOC, and other emissions free. The wood is certified per the guidelines of the PEFC. Made in EU using Binder-Lignin (Wood-Tar).
- Squeak-free floor: High compression strength protects the "click-lock" system of floors, ensures that the floor will not squeak, prevents "springy" effect when walking and increase floor longevity. Can be installed in multiple layers for leveling.
- Breathable material: “Vapor Open” technology prevents accumulation of moisture under the floor and allows air to circulate. Being a natural and porous material, it can absorb 20% of its weight in water and thus prevent a minor leak from spreading.

## Questions & Answers

**Q: Do you have to use a seperate vapor barrier over concrete floors when installing engineered wood floors**
A: Dear rwm925,Thank you for your question!  Vapor barrier should be installed ONLY if the the installation is in a basement that is very damp and humid, or a first floor of a house without a basement and also with the same moist conditions. If the floor you are working on is in upper floors, or not in a  dry humid environment, vapor barrier is not needed. Also, vapor barrier might be needed if the concrete slab is newly poured, and it did not have enough time to cure and dry. Otherwise, by all means, use without any barrier. It will benefit your microclimate in the house.  We hope this helps you and please feel free to let us know if you have any further questions.The SunCo America Team

**Q: I am installing evp or lvp flooring, will this underlayment be ok?**
A: Since vinyl isn't rigid like laminate or other wood type flooring I find out that cork maybe better option because of higher PSI sq ft especially when you use 1/4 option or more. Being this say manufacturer recommend this underlayment and I would use 1/8 version without blink of an eye. Simply I love it after I done laminate floor.

**Q: Can you put down vinyl planks with peel off back (adhesive) on this?**
A: I do not recommend doing that as these are made out of compressed material. So if you glue any thing to it it will just fall apart

**Q: Do I need to adhere this to the current brick paver floor or just lay it on top? If it needs to be adhered, what should I use?**
A: There is no need to to use an adhesive.  You can simply lay our product on top of the existing floor and lay the finishing floor on top of it.  For more comfort of installation, you can use small pieces of adhesive tape to connect the wood underlayment sheets with each other.  However, if the gaps between bricks in your current brick paver floor are deeper than the thickness of the underlayment you want to use, we suggest you to level the existing floor first.  Also, in order to avoid matching of gaps between bricks in your current brick paver floor with lock system of finishing floor, we suggest to lay down the underlayment with an angle against the gaps between bricks in the existing floor as it is written in our installation instructions (you can find a downloadable copy in our listing).  We hope this helps you and feel free to reach out again with any other questions you might have.

### ⭐⭐⭐⭐ Great floor underlayment, very dusty
*by A***D on February 26, 2023*

I used this floor underlayment on a 360 sq ft floating floor. It worked great, installed very easily. You can cut it with a simple swipe of a utility knife and then a bend and the product will break on your line. It WILL make a ton of green dust everywhere while you are installing. After installation our floor was solid and it does seem to have a sound dampening property because it is noticeably quieter in our basement under this floor than previously.
