Well, I did a trial with a few tiles and then covered them with polyurethane. The trial didn't necessarily go entirely to plan but I was able to establish that PU will be too soft. Epoxy is likely to yellow even indoors, so that leaves me with the following solution: 1. make the tiles thicker (not a big deal) use tile selection and a thicker tile bed to enable a relatively flat surface to be made 3. seal it with a thin polyurethane to protect from mess Thanks for the contributions.

wow I love all these suggestions. I was going to suggest a grasscloth wallpaper, because it has wonderful texture. But I'm quite taken with the shelves idea now.

brick wall so no option for cavity sliders gas heaters are already in that middle wall as marked, old heaters i think i need to service them as not sure when its serviced last also has two split aircons on both rooms on the far end no weather seals on entry doors, i can feel cold air is coming under some doors, where can i get the seals or is there someone who can come nd check all doors/windows and seal them tin flat room with not much space in between. I think there is insulation in the middle if not its very hard to do anything without opening up the roof sheets. We have double roller blinds on one side. No curtains on patio door(kitchen).

Hi dreamer, the colorbond wall is part of the original house. I would like to change it to a feature wall but not sure what will be nice.
