1. Damp Checks. 2. 'rapitest' damp tester
This web site has useful information regarding damp in the Motorhome:
http://www.a-tconsulting.co.uk/caravan_tech/dealing_with_damp.htmlIt's not often you see in the Motorhome magazines the subject of DAMP in the bodywork of a Motorhome. Yet this is a continual problem of a caravan type of construction in the UK.
During our non use of our previous Motorhome it spent idle time in a storage area. I purchased a damp salt container. Over the years It would produce about one pint of fluid in 2 months.
Having received a PLASPLUGS Damp Tester for my birthday I got down to some serious checking on my Motorhome. From the sketch below you will see the RED lines, which I considered to be the vulnerable spots, i.e. the constructional joints. At bottom of the sketch you will see the type of insert used in the seams, this makes for a professional finish. The seams used can be lifted with a flexible knife and the two pronged damp tester inserted for a convenient checking.
The damp tester can be purchased from the well known DIY supermarkets and is orientated to the home builder and plasterer. This device is very useful for the Motorhome owner as it's reasonably cheap to buy, I checked during Mar. 2001 to find it cost about £25.
The device works on the principle, a sound is produced if damp is detected, a clicking if normal background damp is detected, to a full blown whistle if heavy damp is detected.
To check if it is working, you place the probes on the palm of your hand and you get a low whistle sound. This is a good indication on how the detector works, also the set level of no damp.
I usually start from the front interior, the ceiling/roof of the van, and progress to the back, checking every seam and vents in the roof.
I then do a similar check to each wall in turn. previous result was as you can see in the sketch below. The blue area is the place where I detected damp. The area which has the largest blue colouring certainly confirmed that the detector was working. This has now beem rectified.
While carrying out this work I made notes similar to the drawing below, you then get an overall image while doing the checking.
The windows have a rubber seal around the perimeter, this is a necessary checking area. This was one area where I expect to find damp, but did not.
