Sticky spots on epoxy surfaces indicate areas that have not cured properly. Several factors can lead to epoxy not curing as intended:

1. Incorrect Mix Ratio: It is crucial to maintain the correct mix ratio of 1 part resin (A) to 1 part hardener (B) for products like TotalBoat TableTop Epoxy. Any deviation from this ratio can result in sticky resin.
   
   
2. Improper Mixing: Thoroughly mix epoxy resin and hardener components to avoid resin-rich or hardener-rich areas that remain sticky. Follow a meticulous mixing process using two clean mixing cups for at least three minutes each to ensure proper blending.
   
   
3. Improper Temperature: Epoxy curing is temperature-sensitive; incorrect temperatures, especially colder conditions, can prolong curing times or prevent it altogether. Thin applications of TableTop Epoxy will not be able to heat up as much during the reaction, slowing the overall cure.
   
   
4. Surface Contaminants: Any contaminants on the surface can disrupt the curing process. Even seemingly harmless substances can interfere with epoxy reactions, leading to incomplete cures.

To address small sticky spots, gently remove them using a small scraper. Clean the area with denatured alcohol or acetone-soaked lint-free cloth, then apply a thin layer of properly mixed epoxy using the 2-cup method. Repeat if necessary to ensure a level surface.
