Thin coat render

[george765]

Is there a product that I can trowel on to an already scratch coated wall (over blocks) that can go a thin as 1mm but thicker where need, perhaps 6mm. I am limited in depth due to decorative bricks already layed along the top of the wall. I hope i've explained ok.
thanks, George

What about something like high build?
