The single greatest cause of damage to any flooring or floor finish is abrasion from dirt and grit. Wherever possible, use walk off mats at entrances and doorways. If mats are placed directly on COREtec floors, use mats without latex or rubber backings to avoid possible discoloration.
Use non-staining floor protectors under heavy furniture, chairs, and tables. Use appropriate window coverings, as direct sunlight may fade the color of the flooring over time.
