Dekalin 9735 alternative? Very expensive.
Not that I need any but is there a cheaper maker for underfloor protection? Not for the metalwork but the ply' floor.
Someone mentioned Raptor but this is metal paint not wood or do I not see the link?

There was a bit of chat about sealing the underneath of our Eribas recently:-

Wax Seal

Wax oil is ok on the metal work but the floor has to be breathable.

I'm trying to work out why the floor must be breathable. The glue lines between the laminates are waterproof. The polystyrene insulation in the middle of the floor sandwich is water impermeable As such the floor is not breathable and therefore would not require a breathable finish.

I often wondered about the underside of the a wooden floor, Rob-Jax (deceased) the Famous Eriba Oracle wrote this on practical caravan website in 2005.


Thoughts on a modern caravan floor: Our Eriba floor is a standard plywood / foam / plywood bonded sandwich, with a bottom breathable membrane and protective coat. If you have this type of floor, don't cover it with any sealant - it needs to breath.

Attempts in the 1970's to seal Eriba floors with an all-round waterproof coating were not successful - many 60's Eribas have their original plywood floor and all 1980's onwards will be original - but probably not those from the 70's. It's nice to have a group of long lived caravans on hand - then you can look back at what was a "good idea" 30+ years ago and see if it really was.

Is the answer the difference between sealing and waterproofing the floor ?
Waterproofing allows the water to be repelled and the plywood dries off.
Sealing would mean that any ingress of water would just sit between the sealant and the plywood ?
