How to Waterproof a mobile Keg-holder?, I have a question on how to waterproof a box I will build Options

[irisheli]

I would like to build my husband a large rectangular "Keg Cooler" on wheels that has taps built off the front. We would like it to be well insulated and hold ice without damaging the container it is built in.

I am thinking I will build a wooden box large enough to hold 3 cornelius kegs and a small CO2 tank. I will put a lid on top and taps on the front. Any ideas on how to insulate and waterproof the inside to hold ice? Is there some sort of hard plastic sheeting I can caluk together?

We mads a trash-can single keg cooler this summer and lined the inside with refrigeration insulation board and a trash bag. It worked well and kept the ice for several days... but eventually the bag leaked and destroyed the insulation. I would like something more long-lasting and "eye-pleasing" this time. Any suggestions?

Thanks!

a few things come to mind - not sure any are all that sensible but maybe i'll get some ideas flowing.

1. spray in pool liner: http://www.rhinoliningsindustrial.com/prod...em_65d-pw/22/46
Might be a bit expensive, but if you prepared the inner surface well and caulked the seams, this might work out.

2. drop in a few layers of fiberglass matting

3. the ghetto rout (which i would probably do), might be to just track down some appropriate shallow plastic bins and build the cooler to acomidate them to drop right in. Hey... maybe you could even find some coolers that would fit each single get nicely, and the tops could be removed... and you potentially then run a hose out of the cooler drain to the back of you cooler box so the melted water would have somewhere to go.

Whatever you choose to do - sounds like a great project. Best of luck with it.

I'd suggest getting thick foam board from a building supply retailer. Use this to fabricate your keg/co2 container to the size you want. Double up the board to achieve a better insulation factor and overlap the 2 layers so that the corners are more sturdy.

Use contact cement to glue the layers together. Then build your wooden "Keg Cooler" around it.

To completely waterproof the interior, purchase this: 5' x 6' PVC Shower Pan Liner - 40 Mil.

Use contact cement to glue the liner to the interior. Also overlap the liner where you have seams so that you achieve a good seal. BTW: I'd recommend water based contact cement so that it will not affect the foam or the liner.

Hope this helps.

Maybe use the plastic stuff [tub round] that lines your shower and calk it and make sure you add a drain of some kind.

+1 on the drain.

I'm also hip to using shower materials. If you use a "membrane", you run the risk of puncturing it, unless of course you install a hard covering over it.

Now that's a lady! Any chance you could give my girlfriend a call? (IMG:style_emoticons/brewboard/biggrin.gif)

I'd go for a box within a box, with insulation between the two. You could do a box of sanded hardwood plywood for the exterior box. Glue and caulk all the edges/seams very well. Put a layer of rigid foam insulation inside that--don't use anything that would lose its effectiveness if it gets wet. Then a similar plywood box on the inside, also with glued and caulked edges/seams. If you're worried that this one will leak into the insulation area, get a can of roofing cement from the hardware store and hit up the outside of the inner box, especially on the corners. It'll be hidden, so appearance shouldn't matter here.

I agree with the idea of a drain, as well.

The shower pan liner I suggested is 40 mil. It's about the same weight as membrane roofing material and fairly tough stuff. Or just get a piece of roofing membrane from the building supply house.

Nice thing about the shower pan liner is you can glue it together using PVC cement (the red hot blue glue kind). I always have a couple cans of that laying around the house.

WOW! Thank you for all the suggestions! I will research them and post info and pics from the project as I complete it! Please keep the suggestion coming!

A woman who wants to do this for her husband? I think I'm in love! (IMG:style_emoticons/brewboard/inlove.gif)

Well, I think I have settled on a design:

I will have 3 kitchen trash cans that you put the kegs and ice into. The trash will have drain spouts on the bottom with mesh covering so ice doesn't clog holes.. that way we can drain water and add more ice if we want. The trash cans will be removable for easy dumping.

Outside the trash cans will be lined with this shower liner (comes in sheets on a roll) that will waterproof and protect from condensation.

Outside the liner will be refrig insulation board that is removable in case it gets damaged.... it's cheap and works great at insulation

There will be a shelf for the CO2 Tank.

Everything will be surrounded in a wood exterior and set on wheels with handles on the sides and taps on the front

( I couldn't find shower surround that was just sheets of plastic or I would have used that... but this way I can cool just one keg or all 3 and use less ice if I want to)

I will post pics as I hopefully finish this project this weekend!

Great! I can't wait to see some pics. Your husband is a lucky man, indeed.

Hey irisheli ... how is this project going?
