Frequently Asked Questions

Yes, Suitable protective clothing including rubber gloves, eye and face protection is recommended when handling resin and catalyst.
Yes, Protite Casting and Embedding Resin can be tinted with universal tints up to 5% ratio. Water based pigments are not suitable as they will change or potentially stop the cure.
  • At 25°c the product will start to gel after 30min.
  • Heat and/or more catalyst will decrease gel time.
  • Cold and/or less catalyst will increase gel time.
There can be several factors why this happens:
  • Not enough catalyst has been used.
  • The resin has been spread to thin. The minimum recommended depth is 5mm.
  • The outside temperature is too cold. On cold days the resin will cure but will take longer.
  • It is not recommended to use in conditions below 10°c
  • *TIP* Expose the resin to U.V light (Sunlight or U.V lamp) to promote the curing process
  • Too much catalyst may have been used.
  • The outside temperature may have been too hot
The resin and catalyst needs to be mixed properly to ensure an even chemical reaction and curing process. Mix resin & catalyst thoroughly for a minimum of two minutes, ensuring to scrape the bottom and sides of the container to ensure it is fully mixed.
If the mould is not made from silicon, latex rubber or polypropylene, the inside of the mould can be coated with Carnauba Wax
No, Protite resins are not food safe or certified
Wet and dry sand the areas that need to be polished, starting with 300 grit and finishing with 3000 grit sandpaper.
It is heat resistant up to 90°c
This is normal and is an indication that the chemical reaction between the resin and the catalyst is taking place.
Polyester based resins have a shelf life of 12 months if not opened and stored correctly in a cool, dry place.
Yes, The working surface can be cleaned and prepared with Protite Clean-Up Solution.
  • Fibreglass matting is used as a filler for repairs
  • Fibreglass cloth is used on boats, canoes and surfboards for a stronger repair.
Yes, Fibreglass can be layered multiple times to increase the strength of the repair. Remember to lay one piece at a time. Once the resin has cured on the initial layer, it can be lightly sanded and the next layer of fibreglass can be laid.
Failed repairs are often due to incorrect surface preparation. Ensure the surface has been abraded and cleaned, removing any loose debris or paint, then follow the repair instructions on the resin kit or can.
It is important to dab out or roll out the resin slowly with a fibreglass roller to ensure no air bubbles are entrapped
Caution needs to be taken when using epoxy resins along with polyester resins. Observe the general rule that epoxy resins may be applied over cured polyesters that have been dewaxed and well sanded, but polyesters should never be used over cured epoxy resins.
Wearing gloves, ensure any leaks or spills are washed away with thoroughly with water.
