Prepare Wall by Removing Obstructions

slick surface before we can start putting it on the wall here we need to pop off all of these uh vent covers outlet covers just because it's gonna be a nice snug fit okay so uh because the styles the vertical pieces they're half inch and so are my baseboards here i think in order for it to actually fit smoothly and not overlap the baseboard i think i need to cut and take off the baseboard first attach the uk board and then put the baseboards on it's the only way to keep it all leveled
