Hi
I have a garden shed recently purchased. Standard shiplap diptreated. I have already painted the exterior after it was assembled last early autumn with creosote.
As the weather now improves, I'm looking to paint the interior with cupranol in a nice bright shade.
My question is how do I prevent this very light colour seeping through the joining etc to the exterior very dark colour... Aside from 'being careful and not loading my brush, is there any tips you may have that I'm overlooking?

Thanks 😊

Solvent based wood preservers like original Cuprinol) tend to sink in -
so usually lighter shades don't cover darker ones particularly. However
some of the modern water based wax loaded ones might since they tend to
form a coating on the surface.

So either go for a solvent based one in a light colour, or fill all the
board joints on the inside with decorators caulk or similar.

The nature of shiplap is that any internal drips are likely to find
their way outside and stain the dark creosote. However, the good news is
that you can then go over the dark creosote on the outside and touch it
up, safe in the knowledge that any drips won't find their way inside.
