Materials/textures

Hello, I am new to Blender and I am wondering why the model I am working on does not show the materials/textures properly. I am using the node wrangler which worked fine on another model but not this one.
I attached an image of the model with an exterior plaster to the wall but it is flat and you can see that it applies it perfectly to the Cube I added beside it. Anyone have any help with the matter please.

How did you unwarp your UV?

I didn’t, I only selected the object as it is consistent material for this texture. Also when UV unwrap when I select the object it does not show up on the left hand side of screen as per image below.

Then you will have to unwrap it manually.
