Making two faces one?

[MirandaBowers]

New to building here, so go easy on me please.

 

I was playing around with the Zimberlab wall kits and I got stumped with texturing.

I have wall A aligned with a second wall (wall B). They are placed side by side to look like one giant flat wall. When I link them, they show up as one part. When I go into edit mode to select a face and try to tint, it will only select the face on one wall at a time. How do I make it so that both of the walls can be tinted as one face together?

 

If that was worded poorly, I can clarify if needed.

Hi

Hold down the Shift key while selecting the faces:

Select face A then hold down the Shift key and select face B. Now both faces will be selected at the same time.

( or simple hold down SHIFT while selecting faces A and face B )
