Water-based techniques refer to methods that utilize water as a primary medium for various applications, including art, cleaning, and construction. In art, these techniques often involve materials like watercolor paints or ink washes, allowing for fluid and dynamic expressions. They are favored for their ease of use and the ability to create soft transitions in color. In construction and maintenance, water-based techniques include pressure washing and water-based adhesives. These methods are environmentally friendly, as they typically produce fewer harmful emissions compared to solvent-based alternatives. Additionally, they are often easier to clean up, making them a practical choice for many projects.
