Smooth, clean, fully cured paint is your best friend. Eggshell or satin finishes often grip beautifully after thirty days, while chalky, dusty, or textured walls can cause early failure. Avoid heavy orange peel, brick, or raw plaster unless skim-coated and primed. Always test a sample square for adhesion, stain transfer, and safe removal.
Residue is the hidden enemy of good adhesion. Degrease kitchen areas, rinse thoroughly, allow complete drying, and finish with an isopropyl alcohol wipe to lift invisible film. Remove silicone splatters, fill nail holes, sand smooth ridges, and prime repairs uniformly. A few extra minutes cleaning can save hours of lifting, reapplying, and trimming later.
Accurate measurements reduce waste, stress, and awkward seams. Map vertical plumb lines with a level, note ceiling dips, and add overage for trimming at baseboards and crown. Plan pattern alignment around focal points like beds, fireplaces, or mirrors. Dry-fit rolls on the floor to visualize sequence, panel numbering, and cut placement before any backing is peeled.
