finishing Tyrolean render coat

Question

So i'm trying to match the tyrolean finish as close as possible on my house. The render has been completely removed on one side of the house and scratch coat has been applied with a 3/1 ratio. I'm looking at buying some of the tyrolean mix that goes with water to try it but can it be applied directly on the scratch coat or does it need a top coat first? 

If i mix my own tyrolean could i put that straight onto the scratch coat or will i need another coat either way?

I'm seeing mixed messages regarding whether it can be applied directly onto the scratch coat or if a topcoat needs to be applied. 

Thanks for any advice.

You should never apply tyrolean finish to scratch coat, it needs a flat and even top coat before you apply tyrolean, thus giving it an all round flat and even finish.

Most rendered buildings have at least 2 coats, scratch coat and a top coat. This allows an even uniformed finish to be achieved whilst also adding to the amount of protection it offers.
Tyrolean can then be applied.
The concern that you have by only applying a scratch coat is that the render may fail or crack and the finish may not be be flat or even.

No you cannot apply to the scratch coat it would look terrible. And you would use so much tyrolean to cover the scratch. So you will need a top coat of render. And you will want a 4.1mix for the top coat of render. Slightly weaker than the scratch coat.
