Repair Methods for Peeling Edges of Office Chairs

The repair of peeling edges on office chairs requires selecting appropriate methods based on the material and the extent of peeling. Details are as follows:

I. Repair Methods for Office Chairs Made of Common Materials

1. Tool Preparation: Water-based environmentally friendly adhesive (to avoid corrosion of the board by industrial strong adhesives), brushes, cloths, and clamps.
2. Cleaning: Thoroughly clean the peeling area with a cloth to ensure there is no dust, oil, or water stains. If there are slight mildew spots or damage at the peeling site, first brush away the mildew with a dry toothbrush, then wipe and disinfect with an alcohol wipe. Allow it to dry completely before proceeding to the next step.
3. Glue Application and Fixation: Use a brush to evenly apply water-based environmentally friendly adhesive to the peeling surface. Align it and clamp it tightly with clamps, maintaining even pressure. Wait for the adhesive to dry completely (usually about 24 hours), and avoid touching or moving it during this period.

II. Repair Methods for Rosewood Office Chairs

1. Determining the Type of Peeling: It is necessary to distinguish between loose mortise-and-tenon joints or surface cracks. For peeling of mortise-and-tenon structures, disassembly and reassembly are required, while surface cracks can be directly repaired.
2. Tools and Materials: Woodworking adhesive (traditional craftsmanship can use isinglass glue, while modern repairs recommend polyurethane or epoxy resin), sandpaper, wooden clamps, or C-clamps.
3. Operating Steps:
   • Inspect the Loose Area: Confirm the extent of peeling and the degree of structural damage.
   • Disassembly and Sanding: If it is a mortise-and-tenon structure, carefully disassemble the joint, sand the contact surface until it is flat, and remove any residual old adhesive.
   • Glue Application and Assembly: Evenly apply woodworking adhesive to the sanded contact surface, align it, and reassemble it to ensure a perfect fit of the mortise-and-tenon.
   • Fixation and Drying: Fix the assembled part with wooden clamps or C-clamps, maintaining stable pressure until the adhesive is completely dry (the drying time may range from a few hours to a day depending on the type of adhesive).

III. Precautions

1. Drying and Cleaning: Before repair, ensure that the peeling area is completely dry and free of stains, as this will affect the adhesive bonding effect.
2. Material Restrictions: For the repair of rosewood furniture, the use of iron nails and chemical adhesives (such as 502 glue) is strictly prohibited to avoid damaging the wooden structure or causing cracks.
3. Professional Handling: If the peeling area is large (e.g., more than 10 centimeters), the structure is complex (e.g., involving multiple layers of boards or precision mortise-and-tenon joints), or the repair is still unstable, it is recommended to contact professional repair personnel for handling.
