Fibreglass Repair Kit (Chop Strand Mat)

  • $21.30 incl GST

Our 4kg, 1kg or 250ml Fibreglass repair kit has everything you need to make a top quality repair.  Can be used for small to large repairs.


  1. Sand the area to be repaired, making sure to sand beyond the repair area a bit so that maximum adhesion is achieved.
  2. Clean the area well, and tape the side that is not being repaired if you dont want resin to leak through.  If the repair needs reinforcing then do so prior to mixing resin.
  3. Prepare the CSM by cutting down to the correct size.
  4. Mix the desired amount of resin required, eg 250ml of resin will cover 0.25m2 of CSM.  You may require multiple thicknesses of CSM to give strength to your repair.  Mix the resin well by scraping down sides of the pottle to ensure catalyst has mixed in properly.
  5. On a piece of cardboard or other scrap material, lay the CSM down and thoroughly wet out the CSM with the mixed resin.
  6. Apply a layer of resin to the sanded repair area and then place the wet CSM over top.  Push out any air bubbles with chip brush.
  7. Repeat with as many layers of CSM as required.
  8. Remove the tape before resin has cured and give a light sand before adding finishing coat.
