Hi just come back from the MechanEx show at Sandown Park and saw the ultimate in garage floors. 5mm hard wearing vynal floor tiles apparantly you can drive forklift trucks over them spill oil, petrol, and acid on them and they will not be affected.

The other advantage is warm floors which helps fatigue standing on cold floors all day, never ever have to paint again. They are so simple to lay the only tool you need is a rubber mallet and a jig saw or hand saw no gluing. Just make sure your floors don't have pot holes in them. Now there I am sounding like a sales man, I am convinced we will be laying a few square meters of this over this Christmas period.
