I have an old wooden trawler that I have setting up as a pleasure
boat. I have stripped out the sodden "pegboard" from inside the hull
and now wish to paint the inside of the hull white to brighten it up.
Is there a paint or compound that will go on and stay on over the damp
wood of the internal hull below the waterline - this is obviously
still very visible in the below deck area?

Hi Tannyt. Try this. clean down the surface if oily by washing with
household detergent. Rinse off. Give the damp wood a coat or two of "
BONDCRETE" or another type of concrete waterproofing liquid. Bondcrete
is water soluble. From a new tin mix it 1:1 . This will help it soak
in, even if the wood is already damp. Then try and get hold of a
"SOLVER" BRAND water based paint called " Armourguard". Although water
based, it is very hard wearing and has 'rubberised' qualities. Hope
this helps.

Thanks for the assistance - nobody else seems to want to weigh in.

Happy to pay!!
