The elimination of hardened resinous coatings from cement-based surfaces requires a multi-faceted approach. Several techniques are employed, contingent upon the epoxy type, age, and the substrate’s condition. Examples include mechanical abrasion, chemical solvents, and thermal methods, each with specific applications and considerations.
Effective residue elimination is crucial for restoring the concrete’s aesthetic appeal, preparing it for subsequent treatments like sealing or coating, and preventing potential surface defects. Historically, harsh and often damaging methods were utilized; however, advancements have led to more controlled and less intrusive procedures that minimize substrate damage while ensuring thorough removal.
