Hi There,
I have not used this group before, but am looking for some advice if possible? Any help would be most appreciated...
Two and a half years ago I had a 30sq metre engineered board wooden floor laid in my lounger/diner by a local professional flooring centre (I am based in Brighton, UK). The plank consists of a 8mm layer of solid Jatoba (Brazilian Cherry) wood on top of a 18mm engineered multiplex board. The brand is Multigarant
The floor is laid over a thin fibrous insulation layer on top of concrete sub-floor. The plank is finished with oil.
Within only a couple of days of the floor being laid, we would hear loud 'snaps' and very fine hairline cracks were appearing across the floor (barely visible to the human eye). We were told that this was normal - that the wood was just acclimatising and that the cracks wouldn't worsen.
A year on in 2005, more and more hairline cracks had appeared and in a few planks, had developed into open cracks of approximately 1mm in width. The manufacturer was called to our house, assessed the floor and told us that Jatoba is a very hard and therefore brittle wood and that such cracking is normal, but was unlikely to get any worse.
Again, we have waited another year and the splitting is getting progressively worse. On some planks it actually looks as if the Jatoba layer is coming up from the board to which it is glued. Many cracks run the entire length of the board.
I am now concerned that my floor is in a permanent and unstoppable decline!
Does anyone have experience with Jatoba flooring? Is this usual behaviour for this wood? My understanding was that an engineered board should be extremely stable and that, regardless of the wood, this should not happen.
Any advice or tales of similar experiences would be greatly appreciated.
Regards,
Tom
