As I didn't win the £20k home cinema competition and wont be converting my garage for a couple of years I am going to paint the concrete floor to make the place a little less dusty. I am planning on using this stuff- https://www.amazon.co.uk/Ronseal-Diamond-Hard-Steel-Blue/dp/B00OYSN5Z6 Have I left it too late in the year to paint as the temperature has dropped considerately over the last week or so or should it be ok? I could even hang an electric patio heater from the ceiling to keep the temps up while the paint is drying. Has anybody used this type of paint and is it hard wearing? I wont be putting my car in the garage but I do play table tennis in there and there will be a running machine and cross trainer going in soon. Also should I use a brush or a roller for the best finish and what preparation is required? It is a new build house so the concrete floor is less than a year old (and very dusty).
