On Christmas day, me, my dad, and my brother-in-law spent some time discussing the brother-in-law's kitchen floor (as you do). The house is late 70's build.
None of us is really sure when the floor tiles were originally laid, but the back of them is a brittle white compound.
What thickness were asbestos floor tiles? And are there any tell-tale signs as to whether these may be asbestos or not?
Cheers
