Weathering

Definition

Weathering refers to the changes in color, texture, strength, chemical composition, or other properties of a natural or artificial material due to the action of the weather.

Purpose

The purpose of understanding weathering is to predict and mitigate the effects of environmental exposure on materials, ensuring the longevity and performance of structures and products.

Examples of Use

• Building Materials: Assessing the weathering of stone, brick, and concrete to determine maintenance needs.
• Paints and Coatings: Evaluating weathering resistance to ensure long-lasting protection for surfaces.
• Outdoor Furniture: Choosing materials that withstand weathering to maintain appearance and function.

Related Terms

• Erosion: The gradual wearing away of material by wind, water, or other natural forces.
• Degradation: The deterioration of material properties over time.
• Corrosion: The chemical breakdown of materials, particularly metals, due to environmental exposure.

Notes

Weathering is a natural process that can be slowed but not entirely prevented. Materials and coatings are designed to resist weathering and extend the life of structures and products.
