As I have said before - this is not my area of expertise, but here goes..........
MP Finish is different to the BG Plaster, you can machine apply and hand apply!
It is left on the wall longer before re working..... one bag goes a lot further...........
If you want to give it a go, get in touch with your local Knauf Rep via your local Knauf stockist, or give the office a ring (01795 424499) and ask for local contact to you, or get in touch with me and I will try to help.
Also, don't just try to use it as you would your normal gear....... read up on it, ask the knauf rep for help! As the guys above have said, it is good once you get used to using it....
Dan - PM me your contact details and I will get the local guy to find some for you!
