Resin chairs are made from a type of hard, flexible plastic. This plastic is used to make indoor and outdoor chairs. Some resin chairs are completely smooth and texture-less while others are designed to look like wicker. You can repair minor damage to these chairs with a two-part epoxy resin repair glue. The glue will strengthen the damaged area and help return the chair to its original strength. In some cases, the epoxy may actually add strength to the chair. This process will take about 24 hours to complete.
Clean the resin chair around the broken or cracked area with a degreasing cleaner and a soft cloth. Allow the area to dry before proceeding.
Remove any flaking parts or pieces that are damaged with a sharp craft knife. Reserve any larger pieces to fit back into place. Dispose of small pieces.
Mix the two parts of the epoxy resin together until they are a uniform colour. Apply the epoxy to the cracked area. Push the broken pieces together for about one minute.
Use a putty knife to scrape away excess epoxy before it dries. Press a texture tool into the surface of the epoxy to give it texture. This may be necessary in the case of textured resin chairs, such as artificial wicker. Allow the epoxy to harden for 24 hours.
Use sandpaper to smooth the resin if the chair does not need texture. The sandpaper can help blend the epoxy in with the original resin of the chair to create a seamless line between the original resin and the new epoxy.
Paint the resin with an outdoor paint if desired to hide the epoxy repair.
