What I did learn from them is that they water tested the seal within 24 hours, I am told by other engineers including the NCC workshop i use that at least 5 days should be left the the sealant to cure. Id like Damians opinion on that one.
Sorry to be so late to this.
However, depending on what sealant they used and the temperature at the time it takes a minimum of 24 hours to skin and a minimum of 5 days to fully set throughout its thickness .If the weather is warm then the sealant will cure slightly faster, but with the kinds of temperatures we have been having, it will take longer to cure fully.
At no time should a pressure washer be used anywhere on a caravan !!!!
Regarding the van itself and the extent of water damage, what are the chest of drawers made of and what are the under seating panels made of?, if MDF then they will have absorbed water and only time will tell if they survive or start blowing out.
You need to ensure that the dealer will be held responsible for any future damage caused to the furniture/wooden panels by this water leaking episode, and get it in writing !
