for any plasterer thats been in the trade for over 5 years and has no C and G or NVQ try superskills, they say, a two day course, but its more a day and a bit (if that), hour or two talking about plastering and rendering and a little paper work to sign, the next day, float and set work, plaster boarding and set, setting beads, applying a scratch coat and some top coat rendering. Sounds easy and it is if you've been plastering a long time and can do this work with your eyes shut. It was free but goverment cuts you know what i meen. They take photos of you doing the course work and thats it you've an NVQ, ready for you cscs card. Superskills are in, Thirsk, North Yorkshire. Its called FAST TRACK for people like you with the skills but no paper work. Good luck .
