I just had a shed installed that will be used for storing bicycles and scuba diving gear (so sometimes it will be a little damp inside). The walls of the shed are made of smooth planed pressure treated wood. The roof is made of particleboard. I'm in the UK so the temperature range isn't extreme.
I'd like to paint the walls and ceiling inside of the shed white and was wondering if I should use any particular paints. I am concerned that if I use a cheap or incorrect paint that it will either flake off or discolour.
For reference, here's a photo of the inside of the shed.
Edit
I've been advised to use Cuprinol Garden Shades on the inside and outside, so any thoughts about that will be welcomed.
