Well for the last two days I have been pouring and finishing coloured black concrete. Its pretty much the same as normal concrete except for the fact that its black and gets on everything and it doesn't bloody come off. I am covered in it. I have one more small pour tomorrow and then I won't be using it for a while, thank fuck. Its shocking, and has changed my normally pale skin to a weird blacky brown. Yay for variety in my work diet. At least the finished product looks good.
