So if you have 5m of 3m width you may want to cut it into .5m*.5m blocks which would take around 10 hrs. Problem is that not all concrete is…

I am not experienced with demolition, but I have done a little concrete removal and a fair bit of cutting. You should be prepared for very slow saw cuts that…

Sally,
I used to be a fastidious industrial floor coating applicator and I even painted floors at the Hastings (Victoria) steel mill where they made colorbond too, and I would just…

I don't think it is possible to make them look now again that way. Problems are that you have to thoroughly prepare the slabs so whatever you use will stick,…

I used to be a professional graffiti remover and we would use full strength stripper on colorbond to remove graffiti. It changes colour a little for a while then goes…
