Installing wide plank flooring - Is not much different, from installing hardwood flooring strips. But with one added important step - adhesives. Yes - sticky, messy adhesives. Regardless of the mess, it's the most important part of wide plank hardwood flooring installations. Of course, this applies to only planks that are wider than 5 inches.
Why is glue so important? The glue is additional fasteners for wide plank flooring wider than 5 inches. If, you don't use flooring adhesives. You are only fastening your flooring boards along the sides of the planks with nails, cleats or staples. Leaving the middle, flexing and floating. Issues you will have in the future are bowing, cracking, noise and total hardwood floor installation failure. Your hardwood flooring will not stay flat. The middle will lift up and you will be walking on a uneven surface. A nail down flooring installation will turn into a sprung floor, eventually.
The glue acts as a vapor retarder. We all know how important a vapor retarder is. We don't want moisture damaging our floor from underneath. We abuse it enough from the top. Not only that, the glue will not deteriorate over time, due to moisture.
The glue is a sound barrier. Why would a sound barrier be so important? If, you own a multi-level home, being able to reduce noise from other parts of the home is priceless. Foot traffic, music, tv and noise in general. Nothing like peace and quiet.
