Protect cut pressure-treated wood.

[Kallebo]

I have a number of pressure-treated boards that I have split in half to match the slope of our balcony. How should I protect the sawn part?

Should I then place the untreated side up or down? Protect with felt paper?

A bit unclear what you are supposed to do.
The timber should be pressure-treated all the way through otherwise it is poor quality.
Pressure-treated timber can be treated like other timber. Oil or paint.

In pressure-treated wood, the liquid does not penetrate the heartwood, which is already rot-resistant.

@Kallebo turn the nicest side upwards, it's probably the pressure-treated side that is planed.

It is meant to be used as a beam on a balcony and is therefore cut at an angle along the length, think of it like a wedge.

It is clear that they do not have any pressure-treated impregnation in the middle.

The nicest side is indisputably the factory-planed one.

Then it will not be visible, I had placed the unsawed side against the concrete.
Ideally, you should place kärpapp between wood and concrete to prevent the wood from absorbing water. But it will last many years without.

I'm also thinking it would be best to have the printed side down. It doesn't really matter since the board will absorb moisture and make everything damp. If I have the sawn side up, maybe it has a better chance of drying between the rains.
