Walls and floors: how to prepare walls for painting and wallpaper?

Preparing walls for painting and wallpapering is a crucial stage of renovation, upon which the durability and appearance of the final finish depend. You should start this process with clear planning and drawing up a detailed action plan. Determine your main goals, allocate a budget for materials, and set realistic deadlines for completing each stage of work.

Make an exhaustive list of necessary tools and building materials, including primer, plaster, putty, and abrasive meshes. Start repair work in small iterations, moving from one area of the room to another. This will allow you to carefully control the quality in each individual area and correct possible mistakes in time.

Before applying materials, completely clean the walls of old wallpaper, paint, dust, and peeling areas of plaster. Thoroughly prime the surface with a deep-penetrating composition to strengthen the base and improve adhesion to subsequent layers. Be sure to check the drying quality of each layer before moving on to the next stage of work.

If you are preparing walls for painting, the requirements for surface quality are much higher than for thick wallpaper. You will need to apply several layers of finishing putty and thoroughly sand the wall to perfect smoothness under side lighting. For wallpaper, a slight roughness is acceptable, especially if dense vinyl or non-woven canvases with a pronounced texture are used.

Always record all material expenses in a pre-created checklist so as not to go beyond the planned budget. Thoroughly checking the results at each step will help avoid costly redos and overuse of building mixtures. Remember that rushing at the wall preparation stage always leads to defects in the final coating.
