Isopon DIY Fibreglass Kits (1/4m2 mat)

Isopon Fibreglass Kits are ready-to-use DIY kits for repairing cracks, dents, holes and imperfections in fibreglass, metal and timber surfaces.
Code: FGK1

 Isopon Fibreglass Kits are ready-to-use DIY kits for repairing cracks, dents, holes and imperfections in fibreglass, metal and timber surfaces.

Typical Uses:

  • Caravans, boats, trailers, bikes and cars.
  • Surfboards, water skis, fibreglass pools and water tanks.
  • Down pipes, leaky gutters, metal roofs and rusted panels.
  • Steel, iron, timber, masonry and aluminium.


  • Strand-chopped fibreglass matting for reinforcement.
  • Available in 3 sizes.
  • Up to 5% paint tint can be added to the resin to achieve a solid colour.


1. Prepare the surface with Isopon Acetone.
2. Cut the chopped strand mat to the required size and allow an extra centimetre around the edges. On tight curves, tear the mat to fit, adding extra pieces if needed. Put the mat on a clean surface until
ready for use (e.g. newspaper).
3. Mix no more resin than what you can use in 30 minutes: 920ml (1kg) resin = 1m² matting; 460ml (500g) resin = 0.50m² matting; 230ml (250g) resin = 0.25m² matting.
4. Mix resin with catalyst: for 100ml resin (cold day) use 2.5 to 3ml catalyst; and 100ml resin (hot day) use 1.5 to 2ml catalyst. 1ml = 20 drops
5. Brush a thick coat of resin onto the surface and then position the fibreglass on top of 
the wet resin. Add another coat of resin taking care not to displace the fibres. Dab it, do 
not brush it. Make sure that every part of the fibreglass is �wet out� thoroughly (with no air 
bubbles). Allow to saturate and use a roller to squeeze the air out of the fibres. Clean up 
with Isopon Acetone.
6. Leave to cure, preferably overnight. Add more layers as required. Additional layers 
should be completed within 24 hours of the last layer curing. If layers are applied after 24 
hours, light sanding between layers is required.

NOTE: When using virgin foam ensure the foam is sealed prior to use as applying resin 
may melt the foam.


Wear suitable protective clothing, gloves and eye / face protection when using this product.
