I am posting this to educate the good people on this forum.
This is an image of a Blackbutt floor that was coated with WATER BASED polish 12 months ago.

This is what is known as Tannin Bleed. This black stain was on virtually every end matched piece in the floor.
The effect is also duplicated if a pet pee's on the floor. Water based coatings are NOT Pet friendly, and they should not be put on all timber species. So let me add this, WATER does not Protect Timber! The proof is in the picture.
