There are several reasons we need to consider why you have
"fish eyes," These are some of the reasons why they can occur.
1. Did I prepare my surface? First seal coat is brushed on in a thin layer and is used to seal any porosity on the surface which will prevent air bubbles/fish eyes from rising in the subsequent flood coats. Once the seal coat has set for at least 4 hours, a flood coat is then applied. The flood coat should be poured onto the surface and allowed to flow out and self-level. You can use a rubber squeegee or a foam brush to help spread the epoxy. One to three flood coats is applied for most table and bar coatings. However, you must wait between 4 to 10 hours before using subsequent flood coats.
2. Epoxy is stressed and spread too thin? Epoxy needs cover your entire area and can self-level to 1/8 of an inch. For most applications, the wood surface on the bar or table should be sanded first and cleaned and dust free. If fish eyes occur, add more epoxy to the spot with the issue BEFORE it cures.
If epoxy has already cured and you have fish eyes, you will need to pour another coat over the epoxy.
3. Did I clean and sand my work area? For most applications, the wood surface on the bar or table should be sanded first and cleaned and dust free. Any moisture, oils, greases or uncured finishes can potentially cause fish-eyes or product curing problems. It is also crucial that any prior stains or finishes be completely dry before beginning.
4. Was the room temperature right? Epoxy should be used in conditions between 70° F to 85° F. The room you are working in should be clean, dry, dust and insect-free. Settling dust can often cause imperfections on the surface of the epoxy as it is curing.
* Make sure you have the proper temperature, use the adequate material for your square footage, carefully follow mixing instructions, be sure to pour mixed epoxy out of the bucket soon after mixing, and torch your epoxy immediately after spreading. If you follow these guidelines you should be more than happy with the results.
