Commercial substrate preparation is critical for installation success. The process begins with removing existing floor coverings and adhesives, often requiring grinding or shot-blasting to ensure a clean, porous surface. Professionals must verify slab moisture levels using ASTM standards and inspect for crack repairs using cementitious patching compounds. The subfloor must be leveled to meet the specific requirements of the chosen flooring, as uneven surfaces will cause premature locking system failure or seam separation in heavy-traffic environments.

What are the best practices for commercial substrate preparation before installation?
Best practices include mechanical surface preparation (grinding or shot-blasting), cleaning to remove contaminants, and verifying moisture levels. The subfloor must meet flatness specifications (typically F-number requirements) to ensure long-term integrity of the installation.
