Subfloor screeding or compounding is a crucial step in flooring installation. It involves applying a layer of material, such as cement or self-leveling compound, to the subfloor. This process corrects any imperfections, fills in low spots, and creates a smooth, level surface. It helps ensure the stability and durability of the final flooring. The screeding or compounding material is poured or spread across the subfloor and then leveled using specialized tools. This creates an even foundation for the subsequent flooring material, such as tiles, laminate, or vinyl. Proper subfloor screeding or compounding is essential for achieving a professional, long-lasting, and visually appealing flooring installation
