I just completed a 48×32 x 18 aquarium stand. Not 100% complete but I want to seal the inside. It will have a sump and water evaporation and loss. I don’t want it to hurt the inside and cause the wood to rot and fall apart. Its just 2×6’s for a frame but, it has maple furniture grade on the outside. I want to seal all of it.

not sure what you mean,are you saying there will be water evaporating inside the stand the tank sits on? if so that could pose a real problem of mold no matter what you seal it with.

my brother has a saltwater aquarium and it has all that plumbing stuff
in the cabinet. . . . it DEFINITELY produces a lot of moisture with the
filtering rocks the water has to pour over to remove the nitrates/nitrites
good call on wanting to moisture proof it prior to assembly !!!
if I were doing one, I would use a house type primer with a mildewcide addative
and a couple of coats of semi-gloss bathroom acrylic enamel white paint on the inside.
any clear that you are comfortable with is good for the outside.

You don’t need to seal it. It won’t fall apart if you built it right.
I’ve made lots of stands and canopy’s I never do anything on the inside.

Yes this is a saltwater tank stand. It will have a 30 gallon sump inside with a container for overflow. Salt creep is very bad and very hard to clean off. I was thinking of Thompsons water sealer with a poly over it. The outside will be stained and sealed with a good poly.
Water? Really?
I built it right. I’ve spent several months building this and am not done yet. Id post pics but it won’t let me. Ive got many more projects in the works I’m gonna need help with.

Water will get on you canopy and inside your stand at some point. Especially with a sump set up. One is frequently in the sump for filter sock cleaning, protein skimmers, adjusting pumps, plumbing issues, adding new equipment, and general sump maintenance. Salt creep frequently an issue. Open back canopies and sumps with air flow will typically keep away mold issues.

Multiple coats of Kilz is used frequently as a stand alone, Rustoleum Marine primer and topside paints were very poplar for years, spar urethanes, and various polyurethanes.

I would highly recommend Reef Central or other aquarium dedicated site for questions like this. You get the best of both worlds… those with a lot of experience/skill to a lot of idiots that try all sorts of bad ideas.

The reason why I have never been asked to finish the inside of a canopy is it will not stop or change anything. The salt creep doesn’t really leave the sump unless you have a leak. My friend that services tanks mops up any splashes with a rag when he does water changes.
Save your money for nice lights and all the cool stuff inside the tank.
I don’t have a tank I just make the stands and canopy’s for a friends business.
No one cares about the inside of the stand

lol I care about mine. Im not the best woodworker in the world and dont have the best equipment but I take care of what I have. So, I want to make sure the inside is taken care of so I don’t have to build another one.

I would not use anything with a mildewcide or thompson on the stand. Any water that splashes on the stand and drips back into the tank will contaminate the tank and effect the corals and inverts.

Epoxy would be your best options but any off the shelf poly or varnish will work fine.

Don’t seal it, Vent it with a small fani Back panel.
