修補墻壁的正確方法是確保墻面整潔、均勻涂抹石膏粉、增加強度層和充分干燥。以下是詳細介紹：12

The correct method for repairing walls is to ensure that the walls are clean, evenly apply gypsum powder, increase the strength layer, and thoroughly dry. Here is a detailed introduction: 12

　　清潔墻面。清除修補區(qū)域周圍的灰塵、油脂和污漬，確保墻面干凈，以保證石膏粉能牢固附著。

Clean the wall. Remove dust, grease, and stains around the repair area to ensure that the wall is clean and that the gypsum powder can adhere firmly.

　　調(diào)配石膏粉。按比例混合石膏粉和清水，使用攪拌器攪拌均勻，直至沒有結(jié)塊或干燥顆粒。

Mix gypsum powder. Mix gypsum powder and clean water in proportion, stir evenly with a mixer until there are no lumps or dry particles.

　　涂抹石膏粉。將石膏糊涂抹在需要修補的墻壁上，使用抹刀或刮刀，確保均勻分布，避免不平表面。

Apply gypsum powder. Apply plaster to the wall that needs to be repaired, using a trowel or scraper to ensure even distribution and avoid uneven surfaces.

　　增加強度層。在修補深度較大或墻面有裂縫時，可以在石膏粉糊上覆蓋玻纖網(wǎng)或使用乳白膠以增強強度和耐久性。

Increase the strength layer. When repairing to a greater depth or when there are cracks on the wall, fiberglass mesh can be covered on the gypsum powder paste or milk white glue can be used to enhance strength and durability.

　　干燥。涂抹完成后，等待石膏完全干燥，通常需要24到48小時。

Dry. After application, wait for the plaster to completely dry, usually taking 24 to 48 hours.

　　打磨墻面。石膏干燥后，使用砂紙平滑表面，去除不平整部分，直至墻面達到理想的光滑度。

Polish the wall. After drying the gypsum, use sandpaper to smooth the surface and remove any unevenness until the wall reaches the desired smoothness.

　　涂刷涂料。在打磨好的石膏面上涂刷與原墻面相匹配的涂料，以增強美觀度和保護石膏墻面。

Apply paint. Apply paint that matches the original wall surface on the polished gypsum surface to enhance aesthetics and protect the gypsum wall.

　　需要注意的是，確保使用的工具和材料妥善保管，避免誤食或接觸眼睛等敏感部位。如果墻面損壞嚴重，需要進行大面積修補，建議請專業(yè)的裝修師傅進行操作，以免影響修補效果和美觀度。

It is important to ensure that the tools and materials used are properly stored to avoid accidental ingestion or contact with sensitive areas such as eyes. If the wall is severely damaged and requires extensive repair, it is recommended to hire a professional decorator for operation to avoid affecting the repair effect and aesthetics.
