膩子粉作為建筑裝飾的核心材料，本質上是墻面修補找平的基材，為后續的刷漆或貼壁紙打下堅實基礎。它主要由基料（水泥、膠粉）、填料（碳酸鈣、滑石粉）及助劑組成，直接決定了墻面的平整度與使用壽命。

　　Putty powder, as the core material of architectural decoration, is essentially the substrate for wall repair and leveling, laying a solid foundation for subsequent painting or wallpaper application. It is mainly composed of base materials (cement, rubber powder), fillers (calcium carbonate, talcum powder) and additives, which directly determine the flatness and service life of the wall.

　　在選購時，了解分類至關重要。國家標準將成品膩子分為一般型（Y型）和耐水型（N型）。Y型適用于干燥的臥室或客廳；而廚房、衛生間等潮濕區域，建議選用添加灰鈣或水泥成分的N型耐水膩子，其粘結強度高且遇水不易粉化。選購時還需認準符合國家GB18582-2020標準的環保產品，確保游離甲醛與VOC含量達標。

　　Understanding the classification is crucial when making a purchase. The national standard divides finished putty into general type (Y type) and water-resistant type (N type). Y-shaped is suitable for dry bedrooms or living rooms; In damp areas such as kitchens and bathrooms, N-type water-resistant putty with added lime calcium or cement components must be selected, which has high bonding strength and is not easily powdery when exposed to water. When choosing, it is also necessary to identify environmentally friendly products that comply with the national GB18582-2020 standard to ensure that the free formaldehyde and VOC content meet the standards.

　　優良的成品膩子粉綠色環保，兌水攪拌即可使用，杜絕了傳統工藝中現場摻入劣質膠水帶來的甲醛污染風險。施工時，需確保基層堅實、無浮灰，通常批刮兩遍，每遍厚度控制在0.5-1.0mm，且建議等前一遍完全干透后再進行下一道工序。

　　High quality finished putty powder is environmentally friendly and can be used by mixing with water, eliminating the risk of formaldehyde pollution caused by the on-site addition of inferior glue in traditional processes. During construction, it is necessary to ensure that the base layer is solid and free of floating dust. Usually, it is scraped twice, and the thickness of each layer is controlled at 0.5-1.0mm. The next process must be carried out after the previous layer is completely dry.

　　驗收時，可用強光手電貼著墻面照射，檢查是否有砂痕或坑洼；也可用指甲輕劃，若無明顯痕跡且不掉粉，說明膩子硬度合格。選對膩子并規范施工，才能讓墻面歷久彌新。

　　During acceptance, a strong flashlight can be used to shine on the wall and check for sand marks or potholes; You can also lightly scratch with your nails. If there are no obvious marks and no powder falls off, it indicates that the putty hardness is qualified. Choosing the right putty and applying it in a standardized manner can make the wall last forever.
