Step-by-Step Repair Process for Rough Plaster Walls

Begin by cleaning the wall surface thoroughly, removing loose debris and dust. For minor roughness, sand the area lightly and apply a bonding primer. Use high-quality plaster mix mixed to consistency, then apply in thin, even layers with a trowel, smoothing each coat before drying. Reinforce cracks with plaster patches where necessary. Allow full curing time, then lightly sand for a flawless finish. Proper ventilation and damp-proofing address moisture issues to prevent recurrence.
