This caravan had become rotten from leaks and damp, we had to replace some of the structural timbers holding the roof. Then we replaced all the wood panelling with plastic sheets, we also replaced the front bed with a new piece of plywood.
First, we had to remove all the cupboards to be able to access the walls, we replaced and treated the rotten support timbers.
We then added the plastic sheets that we cut to fit the shape of the van, these were held in place with strong glue and pushed against each other.
We started adding the cupboards back, we finished with a stick-on wooden finish.
