Hi there Wasyl - of all the planking I have ever done, single planking/double diagonal planking/triple planking on a hull, also, deck planking/veneering I have only ever used Evostik Resin W - which is an exterior grade PVA glue. It isnt 100% water proof but it does do the job,
as long as its sealed to tell you how long it lasts - I have been up in the loft sorting out the Christmas decorations and there is a hydroplane which I built in 1069 just after the Magna Carta was signed
MAKE THAT 1969! AND it is still as strong as the day it was built & that was built using PVA glue. So it has been around a few years.
If you have a look at Vosper RTTL 2751 you will see where I am planking with mahogany planks and I am using the PVA glue there.
aye
