If you are using a simple wall then you just have to set the building material to be the same as that used in the slab.
If you need a composite wall, then create a composite that uses the same building materials as used in the slab.
Actually if you already have a composite set up for the slab and you want the wall to be exactly the same, there is a setting in the composite settings to allow it to be used for slabs and walls.
Or if you just want a quick fix for elevations and 3D views, then you can override the surface materials of the walls and slab edge so they all match.
