Seriously you need to check out the Kerlite cladding. No need to sand, the variety is huge even wood look. All you need to do is put on a thicker screed. As I said you do need a tiler that has laid it before. Once it's down, it will never break. Google it, the range is amazing and really beautiful. I did ask the tiler about using it over slate and he said not a problem. Got mine from tile expo.

Here's a video of an area of water damaged bamboo being removed and replaced Joyzzz. Maybe you'll consider replacing the area in front of your fridge. Like you I also have bamboo in the kitchen (and pot plants throughout the house), but haven't had any issues with spills marking the floor. It's a shame there's so much variation in the manufacturing process resulting in some floors tolerating spills and others not at all. I do have a damaged board though thanks to a guest leaving a tap running causing an overflow...that I wasn't told about until days later, grrr. Fortunately the damage is in a shadowed corner and the sealer is still intact, so it isn't noticeable, just a wrinkled surface to the touch. Which is lucky, because our home is earth-covered and there is nowhere for water to drain out of the sub-floor as we "tanked" it with a sealer to ensure no moisture can make its way in. That board sat there in a puddle for days! I still wonder why only one board suffered damage, very strange...

one problem with laying over the top of an existing floor is that it will create small steps at the doorways and cover up any potential problems that will be even more difficult and expensive to remove after the new floor is installed...i acknowledge that removing the old tile or floating timber floor will be dirty hard work but it shouldn't be too difficult but i suggest that some expert advice will help identify the option that will achieve the best results and removing the skirting boards and replace after the new timber floor is installed for an even better result

I still use the same steam mop that my Mum bought me in 2000. we are now in our third home, and I have 96sqm of living dining kitchen hallway tiles. it still works perfectly. I vacuum area with my Dyson then fill up the steam mop, and off I go. including the bathrooms and laundry, I need to refill twice. It has never let me down. i hover the steam mop over any visible dirt, but generally use it as like a vacuum cleaner, just moving back and forward over area. it is a kenwood steam mop 2000. Until I read this post, I forgot how old it actually is. so maybe look at a kenwood brand, if they still make them
