Hello All,

I am considering doing my garage floor more-or-less by following the instructions here - http://www.ehow.com/how_5208514_install-aggregate-flooring.html. I have found that buying a two part epoxy floor coating and my own choice of aggregate from my local builders' merchant is a whole lot cheaper than getting a readymade solution. My garage is around 400 sq ft. I need to lay a surface around 4-5mm thick

I am a very experienced DIYer and have done a great deal of concreting work but never anything of this kind. Any thoughts on whether it is feasible? I'd appreciate all views.
