Condensation

  1. My poor vw is suffering from condensation while sitting on my drive. A pool of water appears on the cab floor. I have covered it with a waterproof cover but water is still appearing, has any body got any ideas or possible solutions?? Thanks

    Get some silica gel or some cheap de humidifiers from the pound shop, failing that bowls of salt or rice inside do the same.
     
  3. The cover came with the bus when I bought it,it's a just kampers one.

    there's the thing then.... the jk one isn't waterproof - it's water resistant....... i reckon you may have a leak and the cover is letting it in, where is it pooling? and is the pool the low point in that area? chances are it's leaking somewhere and running to that spot.
     
  5. :yeah that:
     
  6. the front window seal could be the culprit ,check if theres water running down the front under the foot wells

    oh and welcome by the way, just noticed you're new, hope you stay - would love to see pic's of the van - we like pic's.
     
  8. The cargo floor of ours was saturated the other day when I opened up. I also have a useless JK cover, however most of the problem was caused by condensation forming on the fibreglass roof. I had taken the head lining off to do some repairs - big mistake in the winter time. On cold nights, condensation will form on any exposed areas. Linings and panels reduce air circulation which reduces the problem.

    The front doors are also a problem area. Even with the JK cover on, water manages to run down the windows into the doors, onto the seat area by the seat belt anchor and then runs down onto the floor area. Check for moisture around the seats. This can be cured by fitting a waterproof membrane behind the door panels.

  9. And Hi as well.
     
  10. IFyou reckon it may be a leak rather than condensation mate, you could run it down to car wash , take a mate , u sit in it , get friend to spray vehicle , dont blast it , most older vehicles will "find" a leak if pressure washed directly, and you may find the weak seal,which really isn"t a usual prob, other way is to scatter the likes of talc powder around where u reckon the watere is enterinand check morning after reasonably heavy rain.if u go 2 car wash , get your mate to "drop" the water from above (best to do this very early or last thing in eve!(from experience!)
     
  11. No cover will stop condensation inside a metal and glass stucture. The air is full of moisture at this time of year and it condenses on cold surfaces (like it does on a bathroon mirror) and I found the underside of my fibre glass poptop was soaking and starting to drip onto the floor. I had forgotten to put my moisture absorbing kit inside for one night. After wiping all surfaces I installed my absorber and collected about a pint of water the next night! Fortunately next day I was heading to my dry storage place where it will spend the next three months. Modern cars have much better heaters, ventillation and aircon which help keep the air inside much drier.
    I use these http://www.amazon.co.uk/dp/B0052CUX76/?tag=hydra0b-21&hvadid=10393825989&ref=asc_df_B0052CUX76 one in the engine bay and one in the cab.
     
  12. hey Doubledecker, nice one for that info, i recently tried living in my van(had to ) and hell, the damp was dreadfull , no doubt me doing the breathe in, breathe out routine contributed! so i"ll try em , cheers !.
     
  13. I keep my van under a JK cover, I keep a couple of trays with cooking salt inside, absorbs moisture in the air inside the van !

  15. My Jk cover is the only chuffing thing that doesnt leak , i was even thinking about cutting holes for the windows and driving with the cover on .Any moisture absorbent thing will need to be replaced once it gets wet ( or dryed out / recharged ) Favourite places for leaks are window rubbers , doors ,door seals and windscreen wiper shaft rubbers , check under the dash for drips and rusty stain marks :mad:

  17. I use industrial silica gel, a 'quality street tin' full of it, not the little sachets you get in a shoe box, if you search on ebay something like silica gel bulk or silica gel 1kg you'll find some, it comes in small orange beads, as it absorbs moisture the colour changes so you know when to regenerate it by gently heating it in the oven to use again & again.

    It's used a lot in some electrical industries if you happen to know somebody...

    My JK cover held out the water for about a year then I noticed water running down the outside of the windows while it was raining and I was doing work inside. The new JK cover with three straps instead of two is heavier fabric. I bought one at a major discount at the JK open day last weekend so I shall see how that gets on.


    Water may be also be coming in through the windscreen surround . I found water running down the inside of the front panel after
     
  19. i used a JK cover for 3/4 years before i managed to get the bus in my garage. i was quite impressed really, yes some days the cover did seem stuck to the body with heavy moisture. but we have a coal fire ( IN THE HOUSE NOT THE BUS) and it reallY did stop soot fall and bird crap from white roof. worst part was the pool that gathered on the roof ontop of the roof rack so put on upside bucket in the roof rack for it to run off..still reckon it was better than leaving it naked to the elements
