It's fixed up with muck that you either mix yourself, or buy ready made. Like a big stodgy glue.
TOP TIP: Do not get a plastic measuring angle thing, they bend and make life hard. Get a metal one and your angles will be straight(er)!

One thing i have learnt from doing up three houses now, all of which were TOTAL wrecks, is that its not worth the time doing things like this (or much else for that matter).
A general decorator will work twice as fast as you, will do a job ten times as good in that time, and you have someone to complain to if it isnt 100% perfect. If you factor in the saved time and the miles better finish, not to mention the removed ballache, they are also really cheap £80-100/day around here.
