Is it too late in the year to render externally with NHL3.5 lime. ( Mid Wales based.)

[dfps]

Hello,

Looking for advice about rendering an external pine end west facing wall with NHL 3.5 lime render.
The house is circa 1870 and has a failed sand/cement roughcast finish on random stonework that was originally built with lime.
The existing roughcast sand cement render was added well after the original house was built but is at least 50 years old.

I have previously rendered with sand and cement and done a lot of internal plastering but lime is new to me.

I am trying to do a lot of research but there is so much conflicting information out there complicated by all the modern polymer type products now being extensively promoted as modern alternatives to traditional lime.

I have read today that the best time to externally render with Lime is spring as this give the lime time to cure to a decent thickness before any frost can affect it.
I had originally planned to do it this month ( September) but am now having second thoughts.

Your opinions would be much valued.

I will probably then come back with some additional follow up questions if that's okay.

Many thanks

Go for it so long as temp ok

He'll probably have made a decision, one way or another, a while ago.
