Hi all. I am trying to figure out what could cause this ripple effect on my newly laid floors. It is oak engineered wood. The underfloor heating hasn't been switched on yet. It was applied straight to the screening with an adhesive provided by the wood supplier. I have never seen this happen before so I am fairly lost here, any advice would be massively appreciated.
Seen it before on engineered. Looks like it's where it's been finished by the manufacturer Sent from my iPhone using Tapatalk
Hi guys Thank you for your responses. 1. When the boards were laid, there were no ripples on them. I still have quite a few boards left over which look fine. 2. Yes you can actually feel the ripples in the wood. 3. When is was installed, no rollers were used, the boards actually clip onto each other. 4. Merit can I ask what you mean by where it's been finished by the manufacturer? 5. I suspect it's where the actual oak wood has come away from the engineered part of the board. I am trying to think of why this could happen. Moisture? If it was moisture then I would suspect the whole board would lift hence my uncertainty. I am considering pulling one of the boards up to see what has happened, I will let you know what we find. Any other ideas please shout. Appreciate the help thanks guys.
Also whats amusing is that the suppliers have responded to the images saying they don't see any problems with the flooring and that it looks beautiful. So they not gonna be any help unfortunately.
How old was the subfloor. Did you have a moisture test before the floor was stuck down? Sent from my iPhone using Tapatalk
How long has it been down? What has it been maintained/cleaned with? Sent from my iPhone using Tapatalk
Has the floor been covered up whilst any other building work has been going on , also the floor looks rather dusty
These ;look like chatter marks to me which can occur when sanding the boards. Presumably, in this case in production. They cannot always been seen at install and only become evident afterwards when the light hits them.
See my earlier comment. Almost certainly the oak will not have come away from the backing layer and the cause will be sanding in production where the boards vibrate slightly causing "chatter marks". Easily missed in both production and installation, but also post installation depending on where they were installed. i.e. if there is no light source or an angle from which to see the reflection of light then it can go unnoticed. I'm not sure what you will achieve by taking a board out.
The floor has been down for atleast 4 weeks before installation. I am unsure of a moisture test occurring Some parts yes and some not, the ripples are happening everywhere.
Ok so interestingly enough the supplier of the wood doesn't seem to see the problem, but other wood suppliers have pointed out that it may be due to the segmentation of the under boards see pics below, the segments line up with the ripples. I now Ben told that this floor should never have been used in this area. Incredible, so many guys have never seen this happen before. The saga continues. Thank you for your comments
This could quite possibly be the case but the boards here were smooth before laying them down. We thinking it could be a reaction between the wood, adhesive and the concrete .
They don't really line up tho do they? And if it's ok in the pack why would it look so bad when it's stuck down? Sent from my iPhone using Tapatalk
Well the lining up may be due to my inaccuracies placing the board to check, or as its a different plank, the boards may be cut at different points, but it does give some indication. I am not saying I have spotted the problem, it's just an idea which made sense at the time of explanation. You say you have seen this before, was it a manufacturing problem?
I've seen pre finished engineered wood floors that look like that. You could tell it was machined into the veneer. From your pictures it's hard to tell if the ripples have been machined into the veneer or if the veneer is actually rippling off the plywood backing. So are you saying the concrete underneath had only been down 4 weeks? If so maybe the moisture is coming through those gaps? Sent from my iPhone using Tapatalk
Maybe you should remove a plank and have the subfloor moisture tested. It may get worse when you turn the heating on. What has the wood floor been cleaned/maintained with? Sent from my iPhone using Tapatalk
