No matter what kind of DIY chest freezer setup you’re building, whether it’s fibreglassing, using pond shield, Linex, or Rhino Liner, sealing the gaps and supporting the base is a must, whether you coat the inside or not.
Seal the Gaps First
Before you even think about coating the inside, sealing the gaps is absolutely required. Using marine-grade sealant or epoxy putty is essential for creating a water-tight seal.
Both of these products are recommended in my ebook, and I always advise letting them cure for the full recommended time. Whether or not you decide to coat the inside later, sealing comes first to prevent leaks and protect the structure long-term.
Support the Base
Next, you need to support the base. Chest freezers aren’t designed to hold water and people stepping in and out, so adding rubber gym floor mats cut to size is critical.
Whether you coat the inside or not, the base needs proper support to distribute the weight of the water and anyone plunging. This step is non-negotiable—it keeps your setup sturdy and safe for use.
A Proven Foundation
By laying these essential foundations, you’re building a setup that’s not only effective but also built to last.
You can always jazz it up by coating the inside later, but the key is getting it right from the start without overcomplicating things. I’m all about keeping costs down while making sure you’re safe and ready to plunge.
Stay Icy,
