Re: Getting rid of damp?
When you have dried out the chipboard and removed the mould you might want to treat the chipboard to make it less porous. It will then be less attractive to the mould.
I would either use Ronseal Wet Rot Wood Hardener or a polyurethane varnish diluted with white spirit.
These will soak into the wood fibres and create a barrier between the mould and its food source.
The downside is that they may alter the flammability of the chipboard.
When I was looking for an alternative to Roundup weedkiller I discovered that acetic acid is a major component of a recently introduced weed killer.
