Obs or Alpine Hut?

[Nebulizer]

Hi Andy

Its a single skin at the moment,and its black because I use Bitumen paint to waterproof it.

I used that paint on the inside of a large fish pond filter system for years, and it never did leak or weep water,and there is no damp on the inside surface of the Obs wall, it will get another coat before the winter sets in though.

There is quite a large selection of suitable paints on the market to choose from.

Hello Helen

You will have to use the same kind of words, but I'm sure it will work well for you too.

I was also thinking he could contact me to say 'goodnight'!!
