I need to join some tanalised planks of wood edeways. The wood is 45mm

Do I have to plane the edges down to untreated wood and then water
proof glue them together, or can I glue tanalised without planing ???

Is there any other methods to join them together ??

The joined wood is not going to carry much stress.

If the wood faces are reasonably flat and you can only see, say, 1mm of
light between them, then a Polyurethane glue will work well. I would
NOT sand or plane the sides to be jointed as a rough surface will bond
better than a smooth one - the important thing is that the mating sides
should be, well, mating. Polyurethane glue foams to fill minor surface
imperfections and is very strong - as it's moisture cured it doesn't
mind the damp.

Thats what the cartridge said too, but it wasnt my experience. When wet
it got a lot weaker, and pulled apart fairly easily.

glued joints in my oak porch..
