Epoxy Resin River Table
Not Cured Properly
There are not many factors that would cause your river table epoxy resin not to cure. Especially if you are using our brand, the only cause would be the temperature, or if only part of the resin is curing, and you have some tacky and uneven surfaces amongst cured surfaces, this results from a bad mixing process.
The first step in any troubleshooting scenario is to come back at the initial stage of our projects and determine if crucial steps or directions might have been overlooked or not appropriately applied. With regards to epoxy not curing properly, there are two leading causes. One culprit is the curing temperature, the other is the result of a flawed mixing process and pour quality epoxy resin, or on some rare occasion, the epoxy resin has gone bad. In this quick tutorial, we will go through simple steps to restore your epoxy river table that has not cured correctly.

Finding The Issue
Removing the Uncured Epoxy
If the curing temperature was set at the right degree, or you've elevated it and waited the proper curing time, then the uncured resin has to go. If the entire batch is still liquid, you can remove a side of the mold and let the epoxy flow out of it. If it is only small spots, you can use sponges and small cups to remove the liquid epoxy. After all of the uncured epoxy is remove, use isopropyl alcohol with wipes to clean all of the surfaces that the uncured epoxy resin was in contact with until there is no more uncured resin.
Sand & Clean
With a grit 220 sandpaper, apply a quick sanding and clean all of the surfaces the epoxy will be in contact with thoroughly, then clean, ensuring there is no more dust and debris. If your river table pour had only a few uncured and tacky parts, jump to step 4. If the entire pour was uncured, follow our next step.
Seal & Sand
Apply a DIY epoxy countertop seal coat to the surfaces that will be in contact with the river table epoxy. Mix only the amount required to prevent loss. Cure for 24h and sand briefly to scuff the surface with a grit 220 sandpaper. This will ensure proper adhesion between the two layers.
Whether you are entirely re-pouring or just pouring over an uneven coat, pour your river table epoxy until you've reached the desired pour height. If the tacky/partially pour layer was 1/8 of an inch or less, you can skip this step and go directly to the next step. Please wait 72 hours at 25°c / 77°F for a complete cure.
With a grit 220 sandpaper do a quick sanding of the entire top; this will ensure the epoxy clear coat adheres to the table. With DIY Epoxy Countertop, apply a flood coat to your river table. Depending on the thickness of the uneven surfaces, you might need more than one topcoat to ensure a smooth finish!
Buff & Enjoy
After applying enough top coat to render your surface smooth & glossy, you can now buff the final coat. A lot of our customers prefer their final coat unbuffed as it gives a similar final product with less effort.
