One unexpected challenge was wall variability. Even on a "flat" surface, slight texture and moisture differences caused color and adhesion issues mid-install. We paused, did a small on-wall test strip, adjusted the print profile, and sealed the surface before continuing, which saved the project. My advice is to always budget time for a test patch and surface prep. Walls are never as uniform as they look, and catching that early prevents reprints and stress Albert Richer, Founder, WhatAreTheBest.com
One of the unanticipated difficulties that I got during the wall mural project was the wall's surface and shortcomings. The artwork appeared to be very accurate in drawing, but as we began to paint, the surface irregularities like bumps, cracks, and rough plaster, particularly in detailed areas, distorted the lines. To tackle this problem, I first sanded and primed the wall for it to be smoother before I made small changes to the design to take advantage of the natural contours instead of working against them. I also employed the use of projected guidelines to keep the precise measurements right even on the uneven sections. Mural designing advices for beginners: Inspect and prep the wall very thoroughly—tiny flaws can have big impacts. Look at the wall's lighting and texture when selecting colors and detailing. Adapt your design to the space—this often leads to a better final result. This method is expected to prevent any unexpected situations and give the mural a professional look.
