Recently, I bought laminate wood parquet flooring (8mm) with an HDF core for my apartment. I intend to use this throughout the entire apartment, excluding bathrooms but including kitchen. It is not rated as waterproof. The shop I bought it from told me that water issues of the parquet always comes from water seeping through the grooves between each plank and through the locking mechanism and reaching the HDF core. To help with increasing the water resistance of the floor, he told me that I can treat the locking mechanism with teak oil.
I talked with my installer, and he said that has never done this or heard of it. I got a bit confused. It is a bit of an extra effort to paint each and every plank with teak oil, and I would like to know if it makes sense. I've tried googling it, but did not find any definitive answer.
I've highlighted in orange the image below, to show where the shop told me to treat with teak oil.
Any ideas if it does help to treat with teak oil? Are there any issues about doing this? I'm also concerned that the floor might be stuck together, and cannot be taken apart easily if I need to change some of it.
