Step 1: Clean and Prepare the Surface

Before beginning any restoration work, it is essential to remove all grease, grime, and residue from the chair. Cleaning ensures that adhesives and resins will bond effectively, preventing issues later. Use a damp cloth to wipe off loose dust, then apply a high-quality degreaser for a thorough clean.

For stubborn or oily deposits, Strong Technical Degreaser for Resin Projects – 100% Natural Formula is ideal. It removes contaminants safely from resin surfaces without causing any skin irritation or surface damage.

Allow the chair to dry fully before proceeding. If the surface remains glossy in worn or patched areas, quickly sand with fine-grit sandpaper to create a lightly abraded, matte surface where repairs are needed. Wipe away dust.

Step 2: Make Structural Repairs

Inspect your resin chair for cracks, deep scratches, or areas where the material has become brittle or broken through. Use a craft knife or fine sandpaper to smooth away any loose or flaking edges around damaged spots. Always work in a well-ventilated space and wear gloves.

For filling cracks and rebuilding missing sections, a dedicated repair kit with fibreglass mat and polyester resin offers long-lasting structural results. The Resin Fibreglass Repair Kit – Complete Polyester Resin and Hardener Set includes everything required. Follow the kit instructions to cut a section of fibreglass, position it over larger cracks or holes, and mix the provided resin and hardener at the correct ratio. Apply with a brush, ensuring thorough, even coverage for a strong bond.

Leave the resin to fully cure at room temperature as directed. Avoid handling the chair until it is set hard, usually several hours to overnight.

Step 3: Refinish the Surface for a Like-New Finish

After structural repairs, you may notice surface unevenness or visible join marks. To achieve a neat appearance, light sanding is recommended. Progress through several sandpaper grades, moving from coarse to fine for a smooth finish. Wipe away sanding dust completely between each grade to avoid surface scratches.

If a clear, glossy surface is desired, apply a thin layer of epoxy resin suitable for casting onto the chair’s surface. “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm delivers a professional, crystal-clear finish and is easy to level. Pour or brush as instructed, always working in a dust-free environment. Allow to dry undisturbed for a flawless surface.

Step 4: Polish for Shine and Protection

Once fully cured, the final touch is to restore gloss and achieve a uniform, smooth finish. This not only improves visual appeal but also helps protect the resin from new scratches and wear. Begin by gently buffing the surface with a microfibre cloth.

For best results, use the “Epoxy Polish” – Epoxy Resin Polishing System. Apply as per the included instructions, working the polish into the surface using circular motions until the desired lustre appears. Where possible, use a polishing pad or holder for even results on larger surfaces.

Common Mistakes and Troubleshooting

Common Mistakes and Troubleshooting

Rushing the curing time, poor preparation, or using unsuitable products can result in patchy repairs or cloudiness. Always allow complete drying and curing between steps. Test polishing on a hidden area first if unsure. Work in a clean, well-ventilated space, and never over-apply resin, as this causes drips and bubbles. Address issues promptly: sand out small imperfections, and clean away residue before recoating or polishing.
