Not a problem as such, I'm just thinking of how I can improve things in
my garage. It's a bit damp and spidery in there, and I'm concerned that
using it for storage might not be a great idea come Autumn and Winter.

It has a concrete floor, brick walls, wood/felt roof and a wooden door.
Is there much I can do to help prevent damp in there? Obviously it's
never going to be totally dry, but I was wondering about sealing the
floor and/or walls with something.

Cheers,
J
