Every so often I buy something which so improves the quality of my 'diy life' that I think 'why the hell didn't I get one of those years ago'.
Previous winners of this self-awarded prize over the years include the Fugenboy silicone sealant profile forming tool':
So... the other day I had a small brick-laying job to do and needed to mix up some mortar. In the past I've always found a clean bit of concreted floor, or an old panel of plywood or something to do this on; however this time I was working at home and couldn't find a suitable board anywhere, or an appropriate area of ground to work on (I did broach the subject of using the kitchen vinyl floor but that didn't fly)... so decided to invest in one of those mixing trays:
It's brilliant. It provides a completely clean, smooth surface and is washable-down afterwards, and the lip around the outside keeps all water and mix contained within the tray. I used it on our block-paved drive (which I didn't want to get mortar-stained), but to be honest if necessary I'd have been comfortable using it on a carpeted floor indoors. (Well, almost.)
I've seen these around for years, but never thought to buy one before - definitely should have!
