The importance of sanding down walls

Sanding down walls is a crucial step in wall decoration, as it significantly contributes to improving wall surface evenness, finesse, and the overall final effect. Whether during the day or night, it is essential to have a handheld light bulb with a minimum wattage of 200 to observe the wall surface's evenness while sanding. Additionally, selecting the appropriate sandpaper for wall sanding is not a matter of coarseness or fineness alone. It is generally recommended to start with fine-grit sandpaper and switch to a coarser grit if necessary. However, a final round of sanding with finer-grit sandpaper is typically required to ensure a detailed and scratch-free wall surface. To enhance the longevity of the homeowner's walls, skilled craftsmen often recommend using water-resistant putty, even if it may present slightly more challenges during the sanding process. Furthermore, it is advisable to sand the water-resistant putty within three days after wall application when its strength is relatively low, and the surface structure is not yet fully solidified, making the sanding process more efficient. To achieve superior results, a two-step sanding approach can be employed, beginning with coarse-grit sandpaper, such as 120 grit, followed by sanding with finer-grit sandpaper above 360 grit. The adhesive strength of the putty directly determines its future lifespan and water resistance. Given favorable conditions, opting for water-resistant putty with higher adhesive strength provides superior long-term value and durability.
