  • Technical Questions
  • How much Glass Bubbles do i add to make my Polyester Resin into a paste?


    It really depends on application but as a general rule start off with half the volume of the resin and stir in well then add more if you require the paste to be more viscous, don't forget to add catalyst to the Polyester Resin first (and wear a suitable mask).
