Why do we grind the surface before applying all floor coatings?
Grinding concrete before applying a coating is important for several reasons:
Ensures proper adhesion: Grinding roughens the surface of the concrete and removes any contaminants such as dirt, oil, and grease. This creates a rough surface that allows the coating to adhere better and prevents it from peeling or lifting off.
Improves durability: Grinding concrete also makes the surface more durable and resistant to wear and tear. This is because the process smooths out any high spots, cracks, or rough patches that could cause the coating to wear unevenly or become damaged.
Enhances appearance: Grinding concrete can also improve the appearance of the surface. The process can remove stains, discoloration, and other imperfections, resulting in a smoother, more uniform surface that looks more attractive.
Increases longevity: Applying a coating to a properly prepared surface can extend its lifespan. By grinding the concrete first, you create a surface that is more receptive to the coating, allowing it to adhere better and last longer.
In summary, grinding concrete before applying a coating is an important step that can improve adhesion, durability, appearance, and longevity of the coating. Skipping this step can result in a coating that does not adhere properly or wears unevenly, which can be costly to repair or replace.
