Polyester resin for ding repair

[surf doc]

I'm getting better at ding repair, but I find that the polyester is harder to work with than the epoxy ding repair kits.

Here's my problem- when I use the epoxy it turns into a nice workable slurry after 20 min or so and stays that way for awhile before it hardens. The polyester, on the other hand, goes from being an unworkable liquid to a hard unworkable gel in a minute or so. This gives me a very small window of time to apply the stuff before it hardens.

Here's the kit I use:

I follow the instructions for measurements but maybe I'm using too much hardener? Does anyone cheat and use less hardener?

have you tried suncure?

The resin is meant to be used with fibreglass cloth.

If you are using the resin to fill a hole, then you need to thicken it with microballs (little hollow glass balls, also called microballoons). There is usually a sachet in the ding repair kits. Mix copious amount of them with the resin you intend to fill the hole with to thicken the mixture (and make it lighter).

If you don't have any the you could probably buy them, they are cheap as chips.

P.s. use a dust mask



Good luck

Wow Ricky this is brilliant and appears to be exactly what I was looking for. They are not included in the kit I buy, which seems odd if they truly work as advertised.

Any damage to a surfboard, regardless of how small the ding is, will affect its strength and integrity.

The fibreglass in a surfboard is what creates and gives it strength, not the foam or blank of the surfboard.

Here's the difference between Fiberglass and Epoxy:

1 Traditional Fibreglass (POLY/PU) Surfboard Technology:
Poly or polyester represents a traditional fibreglass surfboard. PU or polyurethane foam is the foam of the traditional fibreglass board. The foam core is laid up with weighted fibreglass cloth and laminated with polyester resin. These types of surfboards have been around since the 1960s.

2. Epoxy Surfboard Technology (EPOXY/EPS or XPS):
These types of boards are becoming more prevalent and use polystyrene foam (two different types – EPS and XPS), both of which are coated with fibreglass cloth and epoxy resin.

Assuming that you have bought a repair kit, you might need help on the proper actions of how to use your Surfboard Repair Kit. There can be as much as 12 common mistakes on repairing surfboard ding but can be easily avoided provided with the detailed help and guidance. http://www.thesurfguru.com.au/repair-guide-dvd/
