Best sealant for wood?

[Thewes]

My box isn't as air tight as I would like to be and I was wondering if you all have some suggestions on what to seal the inside with? On my old enclosure I used good old silicone and it seemed to hold up okay on the MDF but it seemed to peel off on some places. Fiberglass/resin is out of the question. My new box is birch if that matters. Thanks.

I like to use wood good, and then liquid nails, the real brand, don't use the cheap kind, use gloves and then pack it around the box, give it time to cure.

Eh not exactly I went through almost 2 bottles of titebond II and it definitley holds the wood together but its not viscous enough to qualify as a sealant. I have also tried liquid nails, but its too malleable when it cures.

Also a bit OT here but while I have this thread up, does anyone know the best way to clean off woofers surrounds? My 18s got a bit dusty during construction and I don't to damage the foam surrounds with chemicals.

You could use that Duster Stuff, you know the air in a can.

ive made wood glue 45s bro... thats all u need...

why does it need to be viscous?

and how do u know it isnt sealed correctly? just put wood glue on the inside and outside

subs are dirty whores, let them be the way they want to be, dust covered and all, lol

Wood glue or liquid nails, just lay down a bead then put some cling film over a finger and run it along it for a real nice seal.

For subs, just a very very slightly damp cloth works well for wiping them down.

On all my boxes I use silicone and then resin on top of that. Like the others said liquid nails will work very well and if you want to get a little more serious use PL. It is a sub flooring sealant that will never come off easily and seals pretty much anything.

I use the heavy duty liquid nails and the project liquid nails which cleans up with water....and once it cures its permanent....your main problem is your not taking your fingering and smoothing it over the sealant so it has a better bond to the wood....if you do it right you should never have a problem. The trick is to get it as flat and smooth as possible without being overly thick, that just makes it stretchy and bendable....

Since fiberglass is out of the question I would use the wood glue. Glue the wood together allow cure then use a thick layer of glue on outside of joint and allow the outside glue to seal any hard to see airpockets created. Head to Lowes or home depot to pick up a small can of quality wood sealant. (usually outdoor industrial grade) over the course of a few days add 5 or 6 coats to each joint area. This will provide additional strength and keep your wood solid during heavy humidity, pressure etc.

That is a cheap and easy way without fiberglass.
