Can I buy just the Deep Pour hardener or resin?

No. UltraClear Deep Pour Epoxy is sold only as a 1.5 gallon kit containing one gallon of resin and a half gallon of hardener, which is the 2:1 ratio the product mixes at. The two bottles are packaged and sold together and cannot be ordered separately. The kit is also the only size offered: unlike UltraClear Bar & Table Top Epoxy, Deep Pour does not come in smaller quantities such as quarts, and the hardener is not made in a gallon bottle.

If you believe you ordered only the resin, check the box again. Every Deep Pour order ships with both bottles, so you should have the hardener.

If you have resin left over because a bottle of hardener spilled or ran short, the way to use it is a new kit: https://www.bestbartopepoxy.com/products/ultraclear-deep-pour-epoxy. Shipping is free on all orders. If you would like us to check whether a spare half gallon of hardener happens to be in stock, contact us; we can invoice you for one when it is available, but we cannot promise it.
