Why have you spent so much to learn the easiest form of rendering known to man. anyone wanting to learn this who can already float/render should buy 2 bags, 2 10mm stop bead, a long and short scratch float and serated edge. Go in your garage loft and make a square 2m square with the beads and render it. there is plenty of info on here on how to do it, it really is easy. I dont know how they can drag it out for 5 days even adding the features is simples.
