Glue

Definition

Glue is a bonding agent used to join materials together. It is typically applied in liquid, gel, or paste form, and sets through curing, drying, or chemical reaction. Glue is commonly used in picture framing, art restoration, woodworking, and other craft and industrial applications.

Types of Glue

• Hide Glue: Traditional animal-based adhesive used in fine woodworking and conservation framing.
• White PVA (Polyvinyl Acetate) Glue: Water-based adhesive suitable for paper, wood, and lightweight materials.
• Epoxy Resin: A two-part adhesive that chemically reacts to form a strong, durable bond for wood, metal, and composites.
• Silicone Adhesive: Flexible, waterproof adhesive often used for mounting or sealing in framing and display applications.
• Spray Adhesive: Aerosol adhesive suitable for lightweight paper, mats, and foam mounting.
• YES Paste: A reversible, pH-neutral adhesive used in archival and conservation work, particularly for hinging or delicate paper materials.

Functions of Glue

• Bonding: Joins materials such as wood, paper, mat board, or acrylic.
• Structural Support: Provides stability to frame corners, joinery, or layered assemblies.
• Conservation Use: Certain glues are reversible and safe for use on archival or delicate materials.

Usage Guidelines

• Select the adhesive type appropriate for the materials being joined and the expected longevity of the bond.
• Apply evenly and sparingly to avoid seepage or wrinkling of paper or mats.
• Allow sufficient curing or drying time before handling or framing the item.
• For conservation framing, use reversible, acid-free adhesives such as YES Paste or hide glue.

Best Practices

• Always test adhesives on scrap material when working with new or delicate substrates.
• Use minimal pressure during bonding to avoid damaging artwork or substrates.
• Store adhesives according to manufacturer instructions to maintain shelf life and effectiveness.
