Resin Chair Repair Preparation in Action

See a resin chair repair in progress: from applying degreaser and sanding the surface to mixing repair compounds and rebuilding structural elements. Each step demonstrates clean, methodical technique for best results. Visual guides make these repairs realistic for any DIY enthusiast.

Step 1: Clean and Prep the Damaged Area

Begin by thoroughly examining the resin chair for cracks, chips, or wobbly joints. Surface dirt, grease, and residues must be removed to ensure adhesives or fillers bond properly. Start by wiping the repair area with a clean, lint-free cloth, then apply a suitable degreaser.

The Strong Technical Degreaser for Resin Projects – 100% Natural Formula is specially designed for use on resin, plastics, and composite materials, effectively removing oils and silicones while remaining gentle on the surface. Allow the chair to air dry completely before proceeding.

Step 2: Assess and Secure Cracks or Detachments

For small cracks or minor breaks, secure any detached fragments together and ensure all edges fit snugly. Temporary clamping may be needed to hold parts in alignment. Prepare the surface by roughening the internal edges with coarse sandpaper to promote adhesive grip.

For rapid repairs requiring strong adhesion, apply a suitable two-component adhesive such as the “FixExpress” – Two-Component Epoxy Glue 500g. Mix equal parts resin and hardener according to the product instructions and apply to both surfaces. Hold firmly until the glue sets, then allow to cure fully before handling.

Step 3: Fill Cracks, Holes, and Gaps

After bonding any breaks, it’s time to fill visible cracks, gaps, or dents for a smooth finish. For deep cavities or areas requiring extra strength, a fibreglass-reinforced putty can be applied. Mix the putty with its hardener as directed and use a putty knife or spreader to fill the repair area, pressing firmly to eliminate air pockets.

The CROP 2K Fiberglass Putty – 750 ml + Hardener works well for thick or structural repairs. Build up the putty in layers if necessary, allowing each layer to cure as specified. Once dry, sand the area smooth, moving from coarse to fine sandpaper for best results.

Step 4: Reinforce Large, Structural Damage

If the chair has sustained significant cracks or pieces are missing, reinforcement may be essential. Using a fibreglass mat and resin delivers greater structural stability in these cases. Cut the mat to fit the damaged area, roughen the surface, and position the mat in place.

Prepare the resin in the Resin Fibreglass Repair Kit – Complete Polyester Resin and Hardener Set to the recommended ratio. Brush the mixed resin onto the mat and area, thoroughly saturating the fibres. Allow to cure completely before trimming or sanding any excess.

Step 5: Sand, Finish, and Protect

Once all repairs are completed and fully cured, sand over the filled and bonded areas to blend them into the factory surface. Start with medium grit and gradually move to finer sandpaper, wiping away dust between passes to track progress.

Follow with an optional primer and paint or clear coat to match the chair’s original finish and shield the repair from UV exposure and weather. Ensure the surface is dust-free before painting for a professional result. Allow coatings to dry fully before returning the chair to use.

Tips for Success and Common Mistakes

• Thoroughly clean all damaged and surrounding areas before any repair—debris or grease can compromise bond strength.
• Allow ample time for each repair stage, especially curing adhesives and fillers fully, to ensure long-lasting strength.
• Check compatibility and usage for every repair solution—always follow the product’s mixing ratios and instructions precisely.
• Protect surrounding surfaces from spills and adhesives by laying down protective material before starting work.
• If in doubt about a crack’s depth or the chair’s stability, reinforce with fibreglass mat and resin rather than relying on glue alone.
