Guide

A mural shows every flaw underneath it. Fill and sand old anchor holes, skim any texture, and let fresh plaster or joint compound cure fully, because trapped moisture pushes seams open weeks later. Prime with a pigmented wallcovering primer so the paste grips evenly and the paper can be removed cleanly down the road.

Strike a plumb line for the first panel rather than trusting the corner of the room. Corners are rarely vertical, and a scenic image started off-plumb drifts visibly worse with every drop. Hang to the line, not to the wall's edge, and let the trim allowance absorb the difference at the corner.

Panoramic drops are butt-joined, not overlapped, so the edges meet without a gap or a ridge. Line up the image match at eye level first and work the panel up and down from there, since that is where mismatches are most obvious to anyone standing in the room. A seam roller run gently along the join sets it flat; too much pressure squeezes paste out and burnishes the surface.

For made-to-measure murals printed on one file, the installer decides where to cut the width into hangable strips. Agree on that layout in advance so a seam does not land dead center on the subject's face or a key horizon detail.

Light is the mural's best friend and slowest enemy. Raking light from a nearby window exaggerates any lump or lifted seam, so inspect the finished wall at different times of day, not just under the bright work light you hung it with. Where a wall gets hard direct sun, ask about the ink and pigment fade rating, because saturated blues and reds shift first.

Protect the investment with simple habits: dust with a dry microfiber cloth, address a lifted corner promptly with a dab of seam adhesive before it curls, and keep a labeled offcut from the job. That scrap is your exact color and batch reference if a repair is ever needed.
