I was wondering about this as our neighbour had to stop wasps getting in
under the boards round his flat extension roof and foam was the answer, but
its bloody Orange for goodness sake, It now looks like some alien has
infected his roof and started to come out from it!

At last. A d-i-y thread:-)

Has anyone come across building grade gun or can expanding foam in black?

My house is partly clad in black painted feather edge board nailed to
vertical battens. Poor original fitting, warping and shrinkage has led to
occasional gaps where the ends meet the undertile (verge?)

This allows space for uninvited guests:-(

Googling turns up lots of foam manufacturers/suppliers but apart from red
for fire rating and black for pond/gardening nothing so far for normal
building applications. Can the pond stuff be used?

With Sun exposure and Sadolin painted boards it needs UV proofing and to
resist future re-decoration. Also high ratio of closed cells for water
proofing.

Paint it? Only needed for small patches and I'm trying to avoid major
outdoor decorating jobs this late in the season.
