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.

Talk to a concreter. Will the thickness of the screed fit under your doors and March any transition to other surfaces?

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

Agree with oklouise, check out Dulux renovations range, they have a floor paint, they have a how to video , I have used the one for Ben tops and cupboards and it is great, it’s available at Bunnings.
