Sketch a simple plan for each section, spacing elements evenly and allowing room around doors, windows, and skirting boards. If you’re new to installing, pick one focal area first—like a single rectangular panel or a half-wall band—then expand once you’re confident.
Prep the wall for clean adhesion
Proper preparation is the difference between a crisp finish and a patchy result. Clean the surface to remove dust, grease, and loose paint, then fill minor cracks and sand rough areas smooth. If the wall is glossy or very porous, apply a suitable primer to improve bonding. Lay out mould pieces nearby chalk paint for furniture and dry-fit where possible to confirm spacing and alignment. For best results, work with consistent adhesive coverage and avoid overloading the back of each piece. Keep a damp cloth on hand for quick cleanup so adhesive doesn’t smear into grout lines or edges.
