Yes, got the tools as done patches before -but this is 1" thick in places (the bits of old plaster that's fallen off). I don't want a polished finish as I'm going to be tilling over the area, so thought I'd give it a go myself. I went to Wickes, just checked products & think he's given us duff advice -he told us to buy Thistle Board Finish -but i'm applying it to bare bricks. It's the Thistle product in the red bag i need isnt it???
