How to Install Underlayment for Laminate Flooring on Concrete: Picking the Right Underlay & Installation Process
There’s a long list of things you need to do before, during and after such kind of installation. Having complete focus on process as well as researching prior to the event are important keys here. So, make sure you fulfill both conditions with dedication. Let me help you a bit more deeply below by discussing the basics you ought to know.
Starting Note for Installation
We’re about to walk through the actual installation process. You need to have all the necessary tools and supplies ready. Make sure you are not confused over the project. If possible, go through good research before trying actually.
Another advice I must give is regarding prior to the installation. You must ensure the climate is controlled for at least 2 days of a time period. The room temperature should be at a minimum 65-degree Fahrenheit. Also, make sure there’s not more than 65% of relative humidity.
You are going to need the underlayment, flooring, tape and utility knife or scissors. Also, you may require concrete grinder, level, moisture test kit,
Clearing & Prepping the Area
The surface needs to be generously prepared before installation. Here you need to ensure four requirements to continue.
The floor needs to be clean of any old flooring wax, oil or paint. You should also deal with seals and other debris. There should be no heavy burnishing or troweling. The floor should also not be slick. You can try some concrete grinder to get rid of any sort of coating. The surface will also become a bit rough this way. And that is going to help greatly when using adhesive. If you are using a floating floor that is not attached to the subfloor, you need to make it clean as well.
After cleaning you need to do some leveling as well. Use a long level or tape for this task. The leveling should be something like 3.16 inch uniformed within every 10 feet. Using the concrete grinder make sure to get rid of any high spots. Using a cementitious leveling compound, you also want to fill low spots.
You need to check the moisture level. Use a moisture test kit if possible. If moisture seems off with manufacturer’s recommendation, the dampness needs to be reduced. If the subfloor has wood on top concrete, both need testing.
The concrete needs to support installed flooring, furniture and people in that area. It’s really important you assure structural soundness for this reason. There should not be any crumbling or cracks disturbing the floor.
Also, you need to try this on a concrete floor that is at least one month old. You can try the calcium chloride test. The maximum reading in this check should be 5 pounds/1 day/1k square feet.
Cutting Underlayment for Installation
Once you assure the preparation, repairs and inspection steps, it’s time to start actual function. The 2in1 underlayment usually includes a roll. On one side of the roll, you’ll notice an overlap. Start with unrolling the underlayment to around one width. The film (yellow colored) should face the subfloor. And this means the overlap will be facing wall’s opposite side.
As soon as you finish rolling underlayment from one wall to another, time to cut the first section. Make sure to measure before making a cut. Experts always recommend measuring twice while cutting once.
Flooring Addition & Rolling Out New Underlayment
As soon as you start moving forward with underlayment, add flooring. Once you reach at least one-foot distance, stop flooring installation. This measurement should be from the underlayment’s edge.
Now you need to proceed with unrolling another section. Make sure you do this right up against the before installed section of underlayment. Follow the same tactic, you need to measure and cut accordingly.
You may want to proceed with laying down the entire underlayment at once. But this is not the right way. If you consider having entire control over this project is important, then don’t lay all at once. So that it will end up in giving a seamless and moisture preventing the connection between every two sections.
Attached Overlap & Tape Seam Process
You should always install the following row on top of overlap. Do this when unrolling rows. Overlapping from foam edges is unfavored. If you use the attached overlap, then chances of creating seamless moisture seals increases. So, the rows have better installation results this way.
You need to seal the rows together. Use packing tape for that. This will ensure that the 2in1 vapor barrier underlayment stays in place and keeps functioning right.Keep repeating the process until you reach all areas. And after some hard work, you’ll have the installation done beautifully… Enjoy the Results!
