What gun should I use?

[sparcraft73]

I shall spray render on my house and I have three applications. One base layer and one more layer and last decorative colored render.

I wonder what gun should I use. I've got these two and don't know when to use what gun.
Can anyone describe this to me?

Kindest regards
Claes

What machine are you using?

The top image of the spray gun is a standard gun, this can be used for Base-coats and Mono.

When you say decorative coloured Render are you referring to a Mono or Thin coat?

I've got a Tumac p15 http://www.tumac.se/produkt/p15/ and will spray thick layer glass fibre reinforced plaster and also colored plaster. The nozzle on the shorter gun is 10mm.
