We painted some of our fence panels last year, today I noticed that
there are rusty coloured growths on the painted panels which are
slightly raised.

Does anyone know what this is please?

Sounds like the spore bodies of a fungal wood rot or it might be the
beginnings of lichen growing on the surface. A picture would help.

Lichens are usually pale grey or greenish and slow growing.

Put up a picture on an image-hosting web site, and you'll get an
informed response.

What did you paint the panels with? Did it contain a wood preserver of
some sort, or was it just a fence and shed paint, unspecified?

Thanks for your reply.

I used Cuprinol Garden Shades.

Just took a snap of it.

That's not a public site. Try imgur.

However, the most likely cause is that you have painted over knots,
and they have oozed resin. While you can use knotting or other
specialised sealers (before painting, unfortunately), they only
reduce that a little. I suggest ignoring it.

No, this is a Newsgroup. Why would I try "imgur"?

THIS is a newsgroup, dropbox is a NON-PUBLIC image hosting site, and
you can't view the image without signing in. Imgur allows the public

I have a dropbox account but all I get with that URL is "file not found"
since I don't have a file with that name in my private storage space.

And here. It is possible to get Dropbox to create a link which will
allow anyone using it to see the file. I've just set up a sample link,
of a fairly random file of the yarn bombing in my village, last year:

https://www.dropbox.com/s/vee2wrloblfho0m/IMG_1166.JPG?dl=0

To get a link like that from the Dropbox website, you need to click on
the share dropdown next to the file, and then share by email. From the
webmail box it shows you, you can select to "Create Link" and then to
"Copy Link". Alternatively, in File Explorer, if you right click on the
file, you can "Create Dropbox Link".

Mostly I see JPEG artefacts but the gunge looks to me like pine resin
from a knot as Nick suggested. Is it sticky and smelling of pine?

Red detail on a blue ground is just about worst case for JPEG.

I think its resin too, if its bothering you sand back the affected area
use knotting (white knotting is best for water based overcoats) then
repaint, its unlikely to be 100% but will be less than at present

I'm not so sure. It's along a crack in the wood, not a knot.

If it smells of pine - ignore it. If not - worry. It could be fungal.
