5. Masked Harlequin Diamond Grid

Step-by-Step Guide

A masked harlequin pattern brings classic geometric elegance to a bathroom feature wall using precise grid layout techniques. Paint the entire wall with the lighter background color and let it dry completely over forty-eight hours to ensure the base layer withstands masking tape. Calculate equal diamond dimensions based on total wall height and width, making small pencil marks to form a uniform grid across the wall surface. Connect the marks using low-tack painter’s tape to form crisp crisscross diagonal lines that outline the diamond pattern. Seal the tape edges by painting over them with a thin layer of the base coat paint, allowing it to dry to seal any micro-gaps. Fill in the open diamond shapes with the contrasting topcoat paint, then carefully peel away the grid tape to reveal crisp, two-tone diamond geometric lattice patterns.
