Weathertex Primelock instructions say "Ensure sarking is vapour permeable".

Please have a look at photograph #1

Looks like I've bought the wrong material - no problem - I can exchange it at my local hardware - which product do you recommend ?

Question 2

Please have a look at the first image - 'Rear and Side elevations".

Please look at the upper diagram.

Please also have a look at photograph #2

A driveway enters an underhouse garage area from the left.

The pavers of the driveway need to be level with the upper surface of the slab.

The paved area flows around the side of the house at the same level.

The cladding will need to overlap the top edge of the slab by (say) 30 mm

This conflicts with the requirement that the bottom edge of the cladding must be at least 150 mm above paving.

What do I do.

Question 3

Please have a look at the first image - 'Rear and Side elevations".

Please look at the lower diagram.

We are interested in the area under the veranda, on the LHS of the diagram.

Please have a look at photograph #3.

I would be very grateful on any advice on how I should flash this against the weather entering from this end.
