Quickest Way To Dry Out Damp?
Posted 06 July 2012 - 09:39 pm
I plan on attacking the work over this weekend and am keen to speed up the drying out process to get the damp levels down. I was wondering what the quickest way is going to be to get the damp readings back to an acceptable level to minimize the amount of damage being caused by the damp that is currently present?

It is not wise to dry a van using undue heat in case it causes the frame to warp.
I had damp in a van and had to wait a month before resealing was safe to be carried out.
A damp meter will show how it is progressing. If you can be very sure no warping will happen a warm fan may be used VERY sparingly.

The only way is to remove th einterior wall boards, remove any affected insulation and rotten wood and replace with new.
Internal wall boards are covered in a foil laminate which is waterproof, the outer skin of the van is also waterproof, so when water gets in, it cannot get out without removal as stated.

Sounds like a long time but as long as it isnt worsening then its as good as it gets.
Youd be suprised if you dont already know how ventilated caravans are.

It will slowly dry out now. Brecon is right, in that the moisture is trapped between two waterproof membranes - so a dehumidifier won't be much use, but the seams of the wall board inside are not that well sealed, nor are internal fittings that are screwed into the framework through the wallboard so there is a path for moisture vapour to exit by.
I have heard of people piercing the wallboard with a needle (lots of tiny holes in the dampest areas) to speed the drying, then healing the needle holes with sealant or waterproof PVA glue once the area is dry - but I haven't tried this.

Slowly is my advice. A de humidifer, windows slightly open etc. Failing that, if you have no de humidifier available, windows slightly open and heating on low.
You will be trying to dehumidify the world with the windows open

Once it is all sealed, heat from the sun will do the job - if we ever get any!

Been busy today (and managed to do the work outside too!! sun all day !!). Have finished sealing the rear rail and grab handles and have removed the rear half of the one side rail and cleaned most of the gunk off the van.
Left every vent and window wide open all day to air as much as possible. I've taken the 'slowly, slowly ' advice on board and will just have to bide my time and see what happens.
I was just hoping to dry the van a bit quicker so i could monitor how successfull my hard graft doing the sealing up has been. I guess i'll just have to be a bit more patient !
