Can you over mix epoxy resin?

For example, if you want to mix up 2 cups of epoxy, you must mix 1 cup of Resin and 1 cup of hardener to do so. Never dump the full epoxy containers together and mix either! At times our machines may over-pour the resin or hardener, which can cause you to get more product than normal.

Does resin hardener go bad?

All epoxy resins and all epoxy resin hardeners have a shelf-life. The shelf life of the epoxy resin itself tends to be quite long (2-3 years) but the hardeners are more sensitive and should really be used within 1 year.

Does resin need air to cure?

Use a hot air gun, heat lamp, or other heat sources to warm the resin and hardener before mixing or after the epoxy is applied. At room temperature, supplemental heat is useful when a quicker cure is desired. Warning! Curing epoxy generates heat.

Does epoxy harden without hardener?

On their own, epoxy resins are very stable fluids with relatively long shelf lives. It is only when mixed with an epoxy hardener that they can cure properly. If applied onto a floor without the hardener, the resin would remain a near liquid indefinitely and could not transform into a durable flooring system.

Can resin be used without hardener?

Well no, it won’t harden. It might eventually go dry and crusty, but that depends on the resin, and it would be super brittle in that state anyway.

Why is my resin not hardening?

If your resin hasn’t cured properly, this means that the chemical reaction between the resin and hardener was not able to take place.

How do I calculate how much resin I need?

For a round surface, you will need to measure the diameter. Divide the diameter by 2 to calculate the radius. To calculate volume in cubic inches: (radius squared) X pi (or, 3.14159265) x (desired epoxy coating thickness). Divide by 1.805 to convert cubic inch volume to US fluid ounces.
