Purchased a house in West Scotland a couple of months ago with a sizable shed in the back garden. Seems to be a fair amount of water getting in and starting to blacken (rot?) the wood in various locations. I've cleared the outside of leaves and moss which might transmit the water, the exterior is treated with Ronseal type shed paint and the base is on paving. No sign of any membrane sheeting underneath.
It definitely appears to be getting worse recently so would like to be able to stop/slow the damage. Drying it out is a problem given the weather and season, would obviously like to do this before applying a new coat of paint, probably waiting till spring/summer to do this. Lifting the thing up to give it a better base is a no-go for various reasons.
Any remedial things I can do until I can get it dried and repainted? The doors don't shut properly so ventilation isn't really an issue!
Any tips appreciated.
