How thick can I pour ThickSet in one layer?

Up to 1/2 inch on large surfaces like tabletops and river tables. In small molds holding about 10 fl oz or less, you can go up to 2 inches deep.

What is the mix ratio?

One part A to one part B by volume, so equal measuring cups of resin and hardener. Mix thoroughly and scrape the sides of the container.

How long do I have to work with it?

About 30 minutes at 77°F before it starts to gel, around 70 minutes. Warmer room temperatures shorten that window.

Is it food-safe once cured?

TotalBoat states the cured epoxy is BPA-free and food-safe, which suits countertops and food-contact surfaces.

Will it yellow in sunlight?

The formula is UV-resistant to slow yellowing, but no epoxy is fully immune. Keep pieces out of direct sun for long-term clarity.

How much area does a kit cover?

A gallon covers roughly 24 square feet as a seal coat, or about 3.2 square feet as a flood coat at 1/2 inch. Deep or large projects need more than one kit.
