![]() ![]() What if I forgot the seal coat and have already poured my epoxy? The epoxy will mesh nicely with the stickiness of the seal coat at that point. We recommend mixing and pouring your flood or deep pour coat four hours after you apply your seal coats. For the next twelve hours it will become tacky, a phase it enters as it continues to harden. The seal coat will begin to cure several minutes after you've mixed it. ![]() After my seal coat, when should I pour my flood coat or deep pour coat? If you have an obviously porous wood, or if you're simply not sure, you can apply a second and even a third final seal coat, four hours after each previous one. Is one seal coat enough?įor most cases, a single seal coat will be sufficient. When you later pour on a proper coat, you'll get the strong, resilient bond that epoxy is known for. It also greatly reduces the amount of air bubbles that form. This prevents it from interfering with the bonding process of your flood coat or deep pour coat. When an epoxy seal coat is applied, it seeps into these surface-level pores of the substrate, releasing or trapping the air within. ![]() Still, their presence is a concern because each pore can hold a tiny amount of air or moisture that will diminish the epoxy resin's ability to bond firmly with the substrate. Sometimes these pores are easy to see, but often they are too small. Many materials used as a substrate for epoxy are porous. The thickness of table top epoxy when applied as a seal coat allows it to maintain its position even when applied to the sides of a substrate, instead of sliding downward. You can, though we don't recommend using deep pour epoxy for this step, because it is thinner and takes longer to cure. Can I use deep pour epoxy for my seal coat? Ultimately, though, most similar epoxies should work just fine for seal coat applications. They're typically applied using a table top epoxy-such as our UltraClear Table Top Epoxy-as its higher viscosity lends performs well in sealing porous, uneven surfaces. What is an epoxy seal coat?Ī seal coat is a very thin layer of epoxy that has been applied by hand-typically with a paint brush-to a clean substrate to prepare it for the epoxy pouring step. However, when epoxy does bond with another material, it first settles into any tiny grooves and pores present within the material.įor this reason, we always recommend applying a seal coat to the substrate before you start pouring directly onto the surface.īelow, we explain in detail what seal coats are and why they're essential for achieving a strong, clear finish for your epoxy project.Īfterward, we provide a step-by-step guide to applying a seal coat to your substrate. Other effective materials include granite, most metals, ceramic, concrete, marble, and much more. For example, wood is both one of the easiest materials for epoxy to bond to as well as the most common category of substrate, with many different types of softwood and hardwood being used in epoxy projects around the world. Some materials make a naturally great substrate. Because epoxy bonds so effectively, there are numerous materials that can make an adequate substrate.
