Natural finish is a type of wood finish that does not contain any synthetic chemicals or dyes. It is a type of finish that is applied to wood to protect it from damage and enhance its natural beauty. Natural finish is often used on furniture, cabinets, and other wood surfaces. The term 'ELL' is an abbreviation for the word 'OIL, ' which is one of the most common ingredients used in natural finishes. OIL-based finishes are known for their durability and ability to bring out the natural grain and color of the wood.
