Part 1: Basic Processing Step 1 – Check Wall Base
The primary focus during this step is on inspecting for hollow drums, cracks, flatness, verticality,阴阳 angles (internal and external corners), and the water resistance of the putty. The surface layer of the wall must have sufficient strength, and its quality should meet current national standards.
First, Check the New Wall
1. Inspect for hollow drums and cracks
Hollow areas can significantly impact the adhesion of paint or coatings. These issues are usually identified through visual inspection, tapping, scraping, or wiping with the hand. Any hollow drum must be completely removed, and repairs should be made using matching putty or by applying cement mortar with the same proportion as the original wall mortar. This ensures even coating absorption and avoids visible marks.
2. Surface plaster irregularities
Uneven surfaces from previous plastering can affect the overall appearance of the finished decoration. Before painting, these areas should be sanded down to create a smooth surface.
3. Nail heads on the wall
Nail heads should be cut off and knocked in before applying anti-rust paint to prevent rusting and ensure a clean base for the final coat.
Second, Check the Old Wall
1. Powder, dripping marks, and dust
Use a bamboo broom to sweep the surface and repair any uneven areas.
2. Peeling paint or plaster
Remove any loose or peeling layers of stucco or paint.
3. Cracks
After cleaning the outer layer, different treatments such as sizing and leveling should be applied depending on the size of the cracks.
4. Oil stains or grease
Use alkaline water to scrub and rinse away oil and grease residues.
Xiao Bian concludes: The above steps outline the necessary inspections and treatments for both new and old walls before starting the decoration process. In the next part, we will take a closer look at the essential preparatory work required before finishing the wall construction.

Brass fasteners are used for their physical and aesthetic properties. Brass is utilized due to its high thermal conductivity and corrosion resistant properties, it is suitable for use in hot and cold environments, and resistant to water corrosion, making it a staple of industries such as heating and plumbing. Brass fasteners are largely non-magnetic (like any fastener, slight magnetic properties can develop during the manufacturing process) and resistant to tarnishing.
Brass fasteners are suited for some marine environments, including brackish water and slow current sea water; brass in this environment develops a protective green coating. Brass fasteners are also commonly used with wood applications, as the golden coloring blends well with the tan wood. Brass is a softer metal and must be used with care, always drilling pilot holes and using driver bits that fit the head of the screw precisely to prevent stripping. Brass Bolts also require a pilot hole be driven before installtion.
