Hey so I'm installing an over-the-stove microwave and I have backsplash that prevents the microwave backing frame from sitting flush on the wall. My question is...
1. Should I remove all of the backsplash that would sit behind the microwave?
2. Should I cut 2 six inch pieces from the existing backsplash and put them in both corners so that the backing frame sits flush?
3. Just place a bolt behind the backing frame so that it will act as the filler between the wall and frame?
