What’s Up With the Blue Floor In Our Brownstone Renovation? 

In this episode of Site Visit with NS Builders, I’m back at our Brownstone renovation and checking out the blue floors. Although it looks like a Smurf exploded in here, there’s actually a very good reason for the subfloor color. Let me explain.

WHY IS THE SUBFLOOR BLUE?

The subfloor has been treated with a moisture barrier product—Wakol PU-280 Moisture Barrier—to prevent moisture from making its way into the hardwood. We’re installing it early on in the project because we wanted a continuous layer of protection from moisture before we begin our framing. It’s a preventative measure we’re taking to protect the hardwood floor—and it just happens to be blue. It’s easy to apply—it only took about two hours and a couple of rollers to cover the entire subfloor. And after framing is done, we’ll apply a second coat.     

IT'S NOT OVERKILL—IT’S PREVENTION

One of the biggest things we see in new home projects is that hardwood comes in at a particular moisture content and then the subfloor may be a different moisture content level. Problems can arise when there’s an imbalance between the two surfaces—typically you’ll see cupping or crowning of the hardwood floor. It’s crucial to be within the target balance of both surfaces so the hardwood doesn’t actually absorb moisture from the subfloor and then create problems.

So, it’s not overkill of putting the vapor barrier on top of the soil under our subfloor and then adding a moisture barrier product on top of the subfloor—it’s all about taking preventative measures to ensure this home will be free of moisture issues.
