How long should I wait between applying each coat?

  • How Long Do I Need To Wait Between Resin Layers?
  • You can wait until the first coat of resin reaches a gel-like state, after about 3-5 hours, so that when you pour the second layer, it sits on top of the first layer. The two layers will bond together. On the other hand, if you wait until the first layer is dry to the touch, after about 24 hrs, scuff up the surface with 80 grit sandpaper before applying the second coat. This will provide some tooth for best adhesion.
