hello, i have just finished attatching wooden battons to the bearers of my 51ft narrowboat and am ready to lay my reclaimed pine floorboards...i think!
The battons are 60cm apart and i was planning on fixing the floorboards directly to these (leaving access hatches where i may need to adjust ballast). However i'm wondering if i should be putting ply down first and attatching the floorboards to this? (the bathroom floor will be ply anyway with as i'll be laying something waterproof in there!)
I've also applied cuprinol to the underside of the floorboards, should i also treat the upperside to avoid cupping?
I was wondering if anyone had any advice on fixing them as this is obviously quite an important part that i'd like to get right!
thanks for your time, look forward to any suggestions
