Helin Yatan asked 4 months ago


I have a really important question to ask.

I am making an indoor garden with Okoumé Plywood and I want it to be waterproof, resistant to mold and humidity.

I made lots of research about it but couldn’t decide if I should use epoxy or just lacquer it.

Could you please help me with that?

Thank you for the question.

Wood and water are nearly always a bad mix. Over time, and through continuous exposure, moisture and water will eventually destroy even the best protected pieces of wood. It’s just how nature works.

However, you can do a few things to protect what you have.

First, use a type of wood that is better in the elements than others, and that will give you a good foundation. I am not familiar with Okoume plywood, but hopefully it is made for such gardens, and if so it should have better properties than hardware store plywood when it come to moisture.

Second, use a finish that will cover well, like epoxy, or marine varnish. The lacquer will eventually fall apart with water exposure, because it’s not very resistant to water. The marine varnish and the epoxy will be more durable in my experience.

Finally, try your best to keep the water off the plywood as much as possible, no matter what you finish with. It may not be super easy, but the less you hose your wood with water, the longer it will last.

Hopefully this helps, and happy building.
