MR & MRS B Posted March 21, 2014 Share Posted March 21, 2014 We went to look at our caravan last weekend and discover on one side lots of little bubbles on the paint work in different patches. They don't seemed to have gone into holes. The caravan is about 11 years old, we have had it for a year. We contacted the very large caravan company that we purchased it from and they have told us that they haven't seen this before??? Has anyone got any ideas what is causing them please?

perksm Posted March 21, 2014 Share Posted March 21, 2014 Looks like moisture trapped under the paintwork to me. .must have had repair and repaint at some stage. Theres a similar fault in automotive paintwork called Microblistering but its usually finer. Only remedy is flat off and repaint. .. Quote Link to comment Share on other sites More sharing options...
poolebob Posted March 21, 2014 Share Posted March 21, 2014 I have seen something similar but not to that scale. In my case when I pricked one of the bubbles it revealed a hole below, The aluminium skin was corroding. It was on the roof so I removed the bubbles filled the holes and painted over. Whether it was a long term solution I don't know as I have changed vans, Hope this is not your problem but you did ask. poolebob Quote Honda CRV Diesel Petrol & No caravan now.

wigelywoo Posted March 21, 2014 Share Posted March 21, 2014 (edited) Looks like Damp/Corrosion from the inside And if it is, your Dealer will have seen it before Edited March 21, 2014 by wigelywoo Quote Lunar Zenith Citroen C5 2. 2 HDI Citroen Picasso 1. 6 HDI. , Vauxhall Vectra Design 150 bhp Soon to be, 2014 Sprite Major 4 sr.

CommanderDave Posted March 21, 2014 Share Posted March 21, 2014 (edited) Looks like corrosion from the inside . Behind each bubble is a hole possibly . I cant see a dealer would not be aware of the signs of bubbles in paint and corrosion . The insulation material holds the damp and the wood allowing the aluminium to corrode through . I have seen it in a perfect line down the side of a Motorhome where the wood framing battens are . I have wondered if its anything to do with preservatives and steel nail fixings . If you just carefully look under the paint on a bubble it will show white powder which is the Aluminium corrosion . To correct it if it is corrosion would need to renew the panels .

Reads Posted March 21, 2014 Share Posted March 21, 2014 its a poor panel paint repair. from the pictures it doesn't look like oxidisation resulting from water ingress. when panels oxidise they blister and then they begin to powder and crumble.

Bob From Dunstable Posted March 21, 2014 Share Posted March 21, 2014 I`d better start by saying that I have absolutely no expert knowledge or experience of the bubbling you are experiencing on your paintwork. The other opinions may well be correct and if you investigate one of the bubbles you will quickly establish whether it is corrosion from the inside. However, deep breath, the pattern of the bubbles and in particular the fact that the locker door paintwork is also affected to my mind indicates that it may have been caused by an air borne or splashed chemical. Is your van stored where some sort of accidental splash could have happened ? Is it just on one side of the van ? I suggest you scrape off one or two bubbles and see whether the aluminium has corroded under the paint and if it hasn`t make some enquiries at the storage yard. Are other vans affected ?

If you look at the second picture with the fridge vents the bubbles show signs of being in a straight line which made me think it corrosion rather than a paint problem which would just be random bubbles.

Paul_B Posted March 21, 2014 Share Posted March 21, 2014 Like Reads say a poor panel repair They look like solvent pops which have absorbed water & over-time expanded either by ice or heat into microblisters, you could poke one of the larger blisters with a pin to rule out corrosion.

Guest Posted March 21, 2014 Share Posted March 21, 2014 Looks like a classic micro blister. It happens when spray equipment is not flushed through before first application or when moisture gets into the paint as it's being applied. You could prick one of the blisters on the toilet comp door. ...this can be replaced if you make it worse etc Quote Link to comment Share on other sites More sharing options...
screenman Posted March 23, 2014 Share Posted March 23, 2014 I bet that has been painted ona dampish day outside, or using a compressor that had not been drained. Quote Link to comment Share on other sites More sharing options...

We contacted the very large caravan company that we purchased it from and they have told us that they haven't seen this before??? Has anyone got any ideas what is causing them please? 100% poor quality repair. ...you can see the outlines of the filler & primer. I would recommend you return the caravan to the dealer & insist they repair it properly.

MR & MRS B Posted March 26, 2014 Author Share Posted March 26, 2014 Thanks for your help and advice everyone. We called in an expert and he tells us that the caravan has at some time had a paint job which is now bubbling. It's got the wrong bathroom window too??? So we are guessing that it's had an accident at some time. I think that the reason it's bubbling now is we had to move the caravan it because our pitch was becoming a large puddle and that side was then exposed to the little bit sun that we had. Just very relieve that is not an damp problem. Quote Link to comment Share on other sites More sharing options...
