I'm now feeling the need to make amends for failing to waterproof the underside of my decks.
As a new builder I didn't see any need to do this and no advice in this respect was given.
My decks are not getting physically wet from direct contact but in close proximity to water when sailing the wood is absorbing water content from the air.
This causes small ridges under the deck paintwork due to expansion contraction as the moisture content of the wood changes.
I realised this situation after the first few sailings but the problem has been how do I rectify this.
The only way forward is to remove all the electrics for a start so I have photographed every connection as I've begun dismantling
The issue tends to only affect the area where the deck is closest to water which as the aft section.
So now I'm cleared out here including all debris and spilt lubrication.
I plan to invert the hull and bit by bit spray a couple of cans of lacquer in there until I feel the wood has been covered. I'll wait until the hot weather comes back for the wood to be at its driest.
If I was to start over I would have done the entire deck in Paxolin
