The process involves applying a water-based coating atop a surface previously treated with a solvent-based finish. This technique is often employed to refresh or alter the appearance of objects coated with a durable, glossy layer. A common example is refinishing kitchen cabinets that were originally coated for resilience and ease of cleaning.
This method offers several advantages, including access to a wider range of colors and finishes, improved safety due to lower volatile organic compound emissions, and simplified cleanup. Historically, solvent-based coatings were prevalent due to their durability. However, advancements in water-based polymer technology have made it a viable alternative with comparable performance in many applications, combined with environmental benefits.
