Definition

Noun 1. A sealing substance: A substance, typically a type of clay-based cement or putty, used to pack a joint or coat a porous surface to make it impervious to gas or liquid. It is used to create a tight seal.

Usage

• Luting is a technical term primarily used in industrial, engineering, and construction contexts.
• It refers to the material itself, not the act of applying it. The act of applying such a substance is called "luting" (gerund/verbal noun) or "to lute" (verb).
• Example: "The correct luting is essential for ensuring the pipeline connection is completely leak-proof."

Examples

• "Before firing the kiln, the potter applied a special refractory luting to seal the door."
• "The plumber used a waterproof luting to seal the joint between the two pipes."
• "For this high-pressure application, you will need a chemical-resistant luting."

Advanced Usage

• "Luting cement": A common compound term specifying the material as a type of cement used for sealing.
  • Example: "Dental luting cement is used to securely attach crowns to teeth."
• The term can be used in a gerund form to describe the process: "Luting the joints is a critical step in assembling the vacuum chamber."

Variants and Related Words

• Lute (verb): To seal or coat with a luting substance.
  • Example: "You must lute the edges thoroughly to prevent any leaks."
• Luting agent: Another term for the sealing substance.
• Sealant: A more general synonym for a substance used to block the passage of fluids.
• Cement (in specific contexts): Can be synonymous when referring to a substance used for bonding and sealing.
• Putty: A similar malleable material used for sealing, though often less rigid than traditional luting.

Synonyms

• Sealant
• Cement (context-dependent)
• Caulk
• Grout (for filling gaps, especially between tiles)
• Mastic

Notes on Meaning

• The core meaning of luting is always related to creating an impervious seal. While historically associated with clay-based compounds, modern usage includes various synthetic materials designed for specific sealing purposes in fields like dentistry, plumbing, metallurgy, and ceramics.
