Choosing the Right Adhesive for Furniture Repair: A Comprehensive Guide

Understanding the various types of adhesives available, alongside their unique properties and suitable applications, allows for informed decision-making, ensuring a strong and durable bond specific to your furniture’s needs.
Types of Adhesives
Wood Glue (PVA)
Polyvinyl Acetate (PVA), or wood glue, stands out as a staple in the realm of woodworking. Highly effective products like Osmo Wood Glue form a robust bond in as little as five minutes and completely cure within 24 hours. PVA glues are versatile, accommodating various wood types, such as softwood, hardwood, plywood, and chipboard. To achieve optimal results, surfaces need to be clean and firm pressure must be applied, often with the aid of clamps.
Key Features:
- Quick-setting with strong bonds.
- Works on diverse wood types.
- Suitable for indoor projects.
- Products: Osmo Wood Glue, Gorilla Wood Glue.
Hide Glue
For those seeking authenticity in antique furniture restoration, hide glue is a timeless choice. It’s revered for its reversibility, making it ideal when maintaining historical significance and using traditional crafting techniques. Hide glue’s unique properties make it easy to dismantle joints if future repairs are needed.
Key Features:
- Reversible for future repairs.
- Ideal for antique furniture.
- Maintains historical integrity.
Epoxy Resins
Epoxy resins, like Araldite, boast versatility, making them perfect for repairs that involve mixed materials such as wood, metal, and plastic. While offering a formidable bond, they generally require longer curing times. For example, Araldite 2020 epoxy resin is clear and can be dyed to match particular colours, appealing to those needing custom repairs.
Key Features:
- Bond multiple materials.
- High strength and durability.

Application and Preparation
Surface Preparation
Ensuring surfaces are clean and free from contaminants like dust and oil is critical before applying any adhesive. PVA glues, for instance, demand surfaces purged of previous glue residue. With Tite Chairs®, use solvents like methylated spirits or acetone for an effective clean, roughening smooth surfaces with sandpaper can further increase adhesion.
Clamping and Pressure
For adhesives like PVA and epoxy, the application of firm pressure via clamps guarantees a durable bond. Although Tite Chairs® does not require disassembly, ensuring joints are tightly in place before application is essential.

Preserving the historical essence of antique furniture necessitates the use of traditional materials. Hide glue remains the preferred choice for its reversibility and adherence to time-honoured methods.
