First Step 630-Square Foot Roll Underlayment

I bought 2 First Step 630-Square Foot Roll Underlayment of this for use under my new engineered hardwood floor over concrete. Roberts First Step is not as good as it's predecessor Roberts Harmony 3 in 1. They have found a way to make it cheaper. Top and bottom layers are thinner and more natural to rip with a slip of a tool. The total thickness is slightly thinner also because the Styrofoam pellets used look smaller and are more compressed if I were to do it again. Roberts 630 square feet roll use a different underlayment because in my opinion this one isn't worth the price. I highly recommend this underpayment for any engineered hardwood. I used this on my floor; it sits exceptionally well and is quiet. My basement doesn't make any noise. You won't get this price anywhere!

Review of Roberts First Step 630-Square Foot Roll Underlayment:         

Easy to Install Foot Roller: Easy to install and as advertised. I am happy with the underlayment. Have installed about half of the wood floor and am very pleased with the underlayment. I would certainly recommend it. Very easy the handle and lays well. Seems to be quite.

Polystyrene balls Scatter Easily: Have space to cut the pad, as measuring it on the fly is tricky. The Styrofoam balls scatter quickly cuts you make. I can sweep and vacuum the debris every day. Seal a bit tears in the very tin green thin plastic topside. By First Step Underlay painters used for padding will do. Protect the pad if you will be walking over it to any extent. Take your shoes off if you are working on this material. I would not recommend you have it rising at the edges. Keep it flat. I stapled it down a bit. It helped me to keep it from sliding. Before you start to lay, understand how the sticky tape edge works.

Once you roll, it's hard to get back the previous form. You can remove any cut pieces and put them. Later you may need it, and they will create a snowstorm of white balls around your work area. I like Roberts 70-102-1, I don't know if it is precisely what I need, but it is reasonably priced. My 12mm clicks Laminate went down smoothly over this pad, but I had continually cleared away plastic balls. The pros know – that is how to effectively prep and move on. Like DIY guys should understand a lament job.

Awesome for Users: Excellent product, I have a friend who installed the same flooring but with different underlayment, and she noticed the difference right away. I used this on my floor; it sits exceptionally well and is quiet. My deck doesn't make any noise.

Recommend Finally: Can't stress enough how happy I am with this product — excellent performance and quality. I would highly recommend using this! I have installed five floating floors, and this is the first time I used this product. Any floating floor I ever do will be with this going forward. The product is fantastic. Very easy to work with it. The overlap adhesive worked perfect for me, and I had minimal mess from the white balls — used household scissors to cut things. Later Installed the cheapest floor I could find (in stores) on top of this. It takes all of the echo/hollow sounds out. Also, it gives nice cushion and warmth. Premium First Stem Underlayment application went nice over a poured over the concrete floor. The finished piece compared to the bare concrete was noticeably warmer.

Good Sides: It feels warm when walking on it before installing the engineered floor. It is easy to cut and fit, with the self-adhesive tape on one edge. It is a little fragile, the green film on top is easy to damage with the corner of a plank for instance. It is about 1/8in thick (3mm), and I use a second layer in a few low spots that I realized I had missed when leveling the sub-floor. It works well and can compress a little to absorb minor height differences (1/16 or so)

Drawbacks: You can hear it when you walk on the floor. You are disappointed with this. I wish I would have gone with the felt type underlayment.

Found First Step 630-Square Foot Roll Underlayment easy to lay, cut, and place flooring. There are a lot of small spume balls between the other layers of plastic, so using scissors to cut seemed to work better than a knife, for cutting — no need to add an extra moisture barrier. Roberts 70-102-1 Underlayment sides are probably 1-2 mm.
After I bought so look out for that. Very pleased with the product.
