Markw, this stuff you use, the cim-800.  The picture only showed the tin.  does it paint on really thickly and look like a thick grey fibreglass?

We've been to a couple of shows, Joy and myself, and have seen coops with a really thick grey coating on the roof and wondered what it was.

If it is, it would be brilliant.  Like you said, it makes the roof watertight and as it paints on, there is no way would mites be able to get underneath it.

Joe, don't get too disheartened.  When I started I asked loads of questions, I thought I'd never get there.  Every time I thought I found a way to make life easier it turned out it wouldn't work.

 I have to admit I ignored the advice about not felting the roof, thinking "I'll just keep them really clean and there's no chance they'll get red mite"... A couple of months later I had them!

I learned the hard way!

Hi GrannieAnnie.

I have used the grey fiberglass stuff as well it's an epoxy with fiberglass strands but it is prone to crack as it has very little stretch  in the material. they use it on flat roofs.

The stuff I would always use (800) is a two part rubber a dull Matt black color. you can either brush it on or use a roller, it will stretch like an elastic band. you should apply 2 coats. The second coat is applied one hour after the first coat , it all sets in a couple of hours .

You can paint it after if you wish , a solar reflective paint on the roof might help in keeping the coop cool on hot sunny days. The thing is that you don't need to use wood in your construction. I am planning in using a high impact closed cell foam that is very light. the whole coop would only weigh about 20kg for a 8 bird coop. mind you,you would need to weigh it down otherwise it could blow away. the good thing is you can pick it up and move it as you require.

I am still looking to find coop sizes or a rule of thumb for perches and number of nest boxes sizes etc for 6 to 8 girls before I start to build mine. any pointer would be welcome
