Storm dry on cracked chimney crown - with photo's

[Buzz11]

Hi there,

I have a cracked chimney crown (crown/cap? I think thats what its called) and I was planning on spraying off the moss & green stuff and then applying Storm Dry

 

I'm also going to spray 'patio magic' on the slates to kill off the moss etc

 

Does anyone have advice on this?   Am I doing the right thing?

 

TIA 👍

I’ve seen some stuff, but those chimney caps are hilarious 🤣
