The stairwell walls in older houses are almost always the most worn out, cracked, and damaged walls in the entire home, because they get constant heavy foot traffic, accidental bumps from large furniture being carried up and down stairs, and decades of wear and tear that normal interior walls never see. Instead of spending days repairing hundreds of small cracks and holes in the old plaster, you can install thin 50mm thick EPS Cement Sandwich Panel directly over the entire existing stairwell wall surface. This instantly creates a brand new perfectly smooth undamaged wall surface that is far more impact resistant than the old original plaster, so it will stand up to many more decades of stairwell traffic without getting damaged. The small 50mm thickness of the panel only takes up a tiny amount of space, so it will not make your old stairwell feel any narrower or more cramped than it already is. The panel also adds extra sound insulation that reduces the sound of footsteps traveling between different floors of the old house, making the entire home feel much quieter. This stairwell renovation method generates very little dust and mess, and most full stairwell wall refurbishment projects can be completed in less than 3 working days.
