Self-leveling construction acceptance standards Surface flatness, hollowing, and sand rising of self-leveling are the core factors in quality control for self-leveling leveling works. Based on inspections of construction projects involving wood flooring,PVC, resilient flooring, and plastic flooring across multiple regions in China, including Henan,Hebei, Shandong, Shanxi, Shanghai, Hubei, Anhui, Jiangsu, and Jiangxi, contractors uniformly require

Specifications and requirements for the application of surface paving cushion According to the parameter specifications of gypsum-based self-leveling, this product series achieves strengths of 15MPa, 20MPa, and 30MPa, with flatness exceeding the national standard of 3mm ≤ over a 2-meter straightedge. This series is intended solely for indoor cushion layer applications. Applicable decorative surface layers

Treatment of Various Base Surface Types and Application of Construction Methods In accordance with the current National Standard ‘Code for Quality Acceptance of Construction of Building Floor Engineering’ GB50209-2016, base layer inspections shall be performed. Construction may proceed only after acceptance and when the base surface is free from defects such as sand shedding, hollowing,

        Adequate construction conditions are critical to ensuring the smooth execution of gypsum self-leveling construction, thereby guaranteeing construction quality and results. Considering regional differences between northern and southern areas as well as temperature variations, the following conditions must be met to achieve high-quality gypsum-based self-leveling construction.   1.Construction Temperature (Indoor Temperature ,
