CFR who ever that floor belongs to I'd say they have a moisture problem, am I right?
Well...yes and no!
So, we're vetting a new vendor partner in a totally different kind of flooring material - magnetic LVT. We are literally their first distributor partner here in the U.S. (they are European based manufacturer).
If you're familiar with the Metroflor version of magnetic LVT, this one is the exact opposite. With ours, the magnet is on the back of the LVT, and you use a rollable coating on the floor that has a magnetically attractive material (Ferrous Silicate FeSi) mixed into it. Once the coating is dry, you just snap a line and lay the floor.
There are different options for the coating, an acrylic base (which is what we used), a polyaspartic base, and a "temporary" coating which can be used on walls as well as floors.
First some background...
Our building was built in the 1940's. The slab is on grade with absolutely no vapor retarder. I argued that we should use the polyaspartic since it offers vapor reduction that the acrylic does not. Unfortunately, I was poo-pooed by our ownership for multiple reasons. The floor also has some rolls in it and really should have been dealt with prior to installation. Again, no-go. I was told that "this would provide "REAL WORLD CONDITIONS" compared to what our customers would encounter in the field...".
As part of the process, we did a test install in our breakroom. Everything went fine until we started laying the floor.
- First, I noticed we were seeing some shading variations at the edges of the tile. I've seen a similar pattern before and I knew what that problem was from that previous experience. (It's a decor film issue)
- Second, we started to notice some slight ledging and gapping. That was attributed to the slight rolls in the slab. I think they were being a bit ticky-tacky on that one, but we'll see...
- Third, I noticed that the product has a pretty significant "back-bevel" cut to the edge. Meaning if we look at the floor from the side, the top edge of the floor is touching and there is a gap at the bottom. Not sure that is a good thing at all...
We proceeded with the remainder of the install and have just been watching it for the past couple of months to see if it improved. After working through a couple of things with their manufacturing we figured out the product had an issue.
(I think we saw that already but thanks for confirming it, right?)
Anyway, we made the decision to switch the floor out as a result.
Our sundries rep and I decided to document everything as we were removing the floor to try and provide further detail and feedback both for ourselves as well as our vendor. When we lifted the floor this morning, we saw immediately that there was most likely moisture coming through the acrylic coating we used. However, we had lifted part of this floor over the past two months and there hadn't been any signs of moisture even several weeks after install. That may have been because we're in a pretty significant drought here and we only have had rain in the past two weeks for the first time in quite a while.
At this point, we're lifting up the rest of the floor, and then we'll apply a prep product that the manufacturer offers over the existing acrylic coating, and then apply the polyaspartic coating over the top and lay a new floor.
The nice part is this stuff is super easy to remove. You literally just lift it up and it will release from the subfloor. No sticky mess.
