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.

Accessories Required:

  • DIY Epoxy River Table & Countertop Kit
  • Protective equipment for your safety, gloves, protective eye gear and an apron to protect your clothing
  • Border for your casting mold, such as melamine board, corrugated plastic sheets
  • Tools to build the mold, drill, screws, tape, glue gun or caulking for sealing the mold
  • Sanding block, buffer/polisher
  • Solvent such as denatured alcohol to clean your wood slab and any items that will be in the epoxy river table
  • Brush to apply & scrapper for seal & top coat
  • Sponge, scrapper & disposable cups to remove the bad epoxy resin
  • Isopropyl alcohol

Finding The Issue

Curing Temperature

When the epoxy resin is mixed with the hardener, a thermogenic reaction occurs and starts the curing process. Depending on the formula, the optimal curing temperature differs from resin to resin. DIY Epoxy River Table requires the weather to be at 25°c / 77°F. If the temperature was not at the mentioned degrees, ensure that you bring it up to the optimal temperature and restart the curing process.

Homogeneous Mixture

Ensuring to mix in a round container is crucial to ensure a homogeneous mixture. A square container might leave unmixed substance in the corners. Mixing for 5 minutes is also essential; it ensures that all of the solutions are well mixed and ready to cure.

Epoxy Quality

Trying to save costs for a river table project is never a good idea! Or maybe you purchase a good quality epoxy resin, but the shelf life has expired. Epoxy resin has a shelf life of 1 year. In the case that you did purchase our epoxy and it was not the temperature or the mixtures, contact us immediately, and our expert will assist your whitin the briefest of delays.
