Different Methods of Mechanical Preparation • Sanding: Removes surface residues like adhesives or curing compounds. • Grinding : Levels elevated areas, creating a flatter surface profile. • Scarifying : Opens the surface, making it more porous for adhesives or moisture barriers. • Shot Blasting : Cleans and textures the surface for coating adhesion. Each method serves a purpose based on the site conditions and product requirements. When is a Moisture Barrier Required? If elevated moisture levels are detected in the substrate, a moisture barrier—either a liquid- applied epoxy system or sheet membrane—is needed before installing moisture-sensitive flooring. Skipping this step risks flooring failure and voided warranties. What Comes After Remediation? Once mechanical prep and moisture mitigation are complete, a self-leveling underlayment is applied. This ensures the surface meets the flatness and smoothness tolerances required by the flooring product’s manufacturer, completing the prep process. The Takeaway Floor preparation isn’t just about meeting minimum standards—it’s a strategic opportunity. When positioned correctly, it enhances the performance and longevity of the floor, reduces risk, and boosts profit margins. Educate your sales team, equip your estimators with the facts, and treat floor prep as the asset it truly is.
