Advice on which type of render

[AnnaKH]

Hi,

 

I’m looking for advice on what type of render to go for. We’re building a timber frame house with block and render. The house is in a coastal, exposed site very near a sea loch and a few miles from the sea. I had thought that a silicone render would be best, however I’ve heard bad things about mould and the porosity of it. Can anyone advise what type of render will be most effective in withstanding the elements? Thanks
