Over time, the walls of old houses may develop issues like hollowing, peeling, and efflorescence. This not only affects the aesthetic appeal of the walls but could also pose potential risks to the structural integrity. This article will discuss how to address these problems from four aspects, including: cause analysis, treatment methods, material selection, and maintenance.

One, Analysis of Causes for Hollow Sound, Peeling, and Powdering
The occurrence of hollow sound is mainly due to gaps between the coating and substrate of old walls, as well as insufficient adhesion between walls. Peeling and flaking are generally caused by wall coating aging, water penetration, and poor ventilation, among other reasons.
II. Method of Handling
1. Tack Filling: First, knock down the hollowed areas, clean them thoroughly. Then, apply the tack filling agent with a brush or scraper to the wall, allowing it to penetrate the gaps. Once the agent dries, proceed with wall patching to ensure the wall's flatness.
2. Peel and powder treatment: Thoroughly remove the peeled and powdered coatings with a spatula or electric tool, followed by sanding or grinding with sandpaper or a sanding wheel to clear loose materials from the wall. Next, use wall patching mortar to fill in, restoring the wall's flatness. Apply primer and finish paint to protect and beautify the wall.

Section 3: Material Selection
1. Void Filler: Select a void filler with excellent penetration and adhesion properties to ensure it can fully penetrate into the wall and bond firmly with it.
2. Wall Repair Mortar: Choose high-strength wall repair mortar with excellent adhesion and durability to ensure the repaired walls can withstand the test of daily use.
3. Primer and Finish Paint: Select primer and finish paints with strong opacity and durability to effectively protect the walls from peeling and chalking, enhancing the overall appearance of the wall.
Section 4: Maintenance and Care
After completing the wall renovation, regular maintenance and care are crucial. The following points can help you keep the walls in good condition:
Avoid using sharp objects to collide or scratch the walls to prevent damaging the surface coating.
2. Regularly inspect the walls for any new hollowing, peeling, or powdering, and promptly repair any issues found.
Maintain dry and well-ventilated walls, avoiding prolonged high humidity conditions, which helps prevent moisture on walls and the growth of mold.
4. Regularly clean the walls by using a soft cloth or a wall cleaner, but avoid using overly harsh cleaning agents.
In summary, hollowing, peeling, and powdering of old wall surfaces is a common issue, but with proper treatment methods, selecting the right materials, and regular maintenance, we can effectively address these problems and restore the wall's aesthetics and durability. Correct treatment and maintenance can revitalize old walls, providing a more comfortable and delightful living experience.
