Tank stand interior paint and ventelation

[BlackTip]

I am almost done with the frame. In case of leaks, I designed the bottom of the tank to be like a basin. It probably can hold 5-10g of water in it.

1- What are my interior paint options? The bottom is 3/4 plywood. I want something that prevent leaks.

2- The back of the stand will be covered with 3/4" plywood. Side will be covered with hardwood. There will be few holes for electrical wires. Do I need to make large opening for ventilation?

Thanks,

Seal off all seams with a paintable caulk and use Kilz primer and a good exterior gloss white paint. You will be happy with the end result.

Exterior paint is not recommended to be used in the interior. I think it releases toxic gases, but I am not exactly sure on the reasons.

I siliconed all the interior joints and coated with a few coats of kilz.

I painted the frame of the stand and all interior wood with kilz and then an oil based white gloss paint. I then bought and cut a piece of laminate and glued it to the bottom. I followed that up by caulking around outside of laminate with silicone.

Water tight and looks nice.

I used an exterior paint-able caulk for the seams. Then rolled on 2 coats of kilz. Then rolled on 2 coats of white Appliance epoxy.

Results are AWESOME!

I have always added a couple of vents near the bottom and near the top for ventilation. Try for cross flow if possible.

I use spar urethane and phenoseal.

Use the White Epoxy Appliance Paint from Home Depot. Made by Rust-oleum IIRC. Available as a brush on or spray. No primer is needed, it is pretty much a waste of time and money.

Kilz is a primer, and killz by itself is not much for longevity, it needs a top coat.

And yes you need a well ventilated stand. Large cutouts in the back panel is preferred. You can use active (fans) for cross ventilation (end to end) in conjunction with the cutouts, but your evaporation rate will go up, which is fine if you need cooling for the system. If the stand is sealed you will have problems with mildew (despite the paint used) and you will have CO₂ buildup causing pH maintenance issues, as well as more aggressive corrosion of metal components inside the stand, such as door hinges, pump casings, what have you.
