Can you give more information, perhaps an image/screenshot example?
Note that you may not even need to use the brush.
There is a technique you just use Blur (Gaussian Blur), and another in which you use the Clone Tool.
Actually all these techniques can even be used in the same image, it is the taste of each.
But is vague because your brush is not loading
