missosoup-117 Oct 2009 20:31Hello,
We had a professional install vertical grain bamboo parquet flooring (light brown, unfinished) in our new build. After installation, the flooring was oiled, but it now appears blotchy. The spots are not due to the different vertical parquet strips themselves, but look like light and dark patches or even streaks on the floor.
After we raised a complaint, the installation company came back to do local touch-ups and oiled the floor again (for the fourth time). However, there was no improvement. The expert has no explanation for this. He said there are supposedly no specific guidelines for industrial parquet regarding this issue. However, the problem is not the variations between individual strips, but the blotchy appearance after oiling. We left the floor for 11 days to see if the spots would disappear, but there was no change.
My question: What can we do now? Should a different oil have been used for bamboo?
Thank you very much for your help.

Hello missosoup
The bamboo vertical grain strips consist of narrow pieces from bamboo stalks. These are first glued together. When such pieces are installed as glue-down parquet, adhesive residues can get trapped on the surface. This can happen either from the full-surface gluing or during manufacturing. Therefore, my question is: was the parquet sanded before oiling or not? If it wasn’t, the problems you describe could be caused by that.
Bamboo parquet absorbs very little oil. Water further blocks this already low absorption capacity completely. In the end, the emulsified oil remains on the surface and has to cure there somehow. This does not look good aesthetically and is hardly the right choice in terms of performance.
For this reason, the bamboo parquet must be sanded so that it is ready to absorb finish. Important: Do not use high solid oil, but rather a deeply penetrating, solvent-based oil that contains enough curing oils and resins.
I would also recommend checking again with the parquet manufacturer. Normally, data sheets or instructions should provide recommendations on how to treat their products, especially regarding surface preparation.
If the “light brown” tends more towards a “coffee brown”—so rather dark than light—then with film-forming oils there is the additional issue that any mechanical wear becomes clearly visible.
