DH and i did ours (at a previous house). You have to be pretty strong to be able to work the machine and control it so all your movements are smooth. The edging machine is particularly tricky. We took the skirting boards off which alllowed us to get bit closer to the wall. they looked awesome when they were done. i couldn't have handled the machine by myself (but i'm a bit unco), so DH did most of the machine work.

The lambswool applicator thingy is the best for putting the colour on. We used a water based 'Cabbott's Clear Floor', which is really long lasting and not as stinky as 2-pac. When putting this on, you want really long smooth strokes and to go over everywhere just once each coat. After the 1st coat, we lightly sanded to get rid of any rough bits (with a hand sander). you want to get rid of all the dust before the 'paint' stuff each time.

good luck!
