Setting out to form plaster corner stone bands firstly sellect the correct timber batterns 4x1 [pencilround or splayed skirting. Then sellect 2x1 batterns then you can begin to set out your corner to form a solid edge. To do this first fix your 2x1 battern to the wall, keeping it back from the corner edge about 12mm checking its level both ways once this is achieved then, fix the 4x1 timber on top of the 2x1 allowing it to petrude to the desigherd thickness required, then prime your backing coat and apply a5x1x1 render mix with lime, allow to cure, then float upto asmooth finish ready for marking and cutting out allow 16; width x 10; depth roughly or to one's preference .
