plywood

what is the best kind of plywood to be used in building a cage for a dumeril boa ???

[PDXErik]

Melamine or something with a waterproof coating on it.

I don't know about sizes, but you definitely want something more than paint in between your snake's poop and the raw wood besides paint.

Be really, really careful about plywood--a lot of it is made with pine (unless you buy a more expensive birch plywood or something). Moreover, it also contains phenol formaldehyde resin. To make plywood, thin layers of the wood are bonded together with the resin. The phenols in pine and some other evergreen woods are toxic to snakes, and the phenol formaldehyde resin is also toxic. The outgassing of the phenols could be fatal for the snake.

When Erik says to use melamine, he's steering you away from the toxic woods as well as noting the need for waterproofing.

Hehe, thanks, but all I was thinking about was the poop factor. Impossible to clean wood properly.

Thanks for the head's up on the poisons.

if youre going to use plywood you should use a decent quality brand thats finished on both sides and seal it with a natural wood sealer. youll have to apply a few coats which is time consuming but when youre finished youll have a great looking enclosure.

IF you're hellbent on using plywood, you should seal it with many coats of marine sealant and allow it to off-gas for weeks. Normal old melamine WILL warp and prove completely useless in no time at all.

[kriminaal]

Not to complicate things further but, make sure the marine sealant or epoxy is aquarium safe. Much of the marine products used for boats have dangerous levels of VOC's.
Combine that with a small enclosure and eventual nervous system and brain damage can occur.

My wood enclosure is pressboard with vinyl floor tiles. It's heavy as hell, but it holds up to everything.

Epoxy is not safe--it continues to outgas for a long, long time, and it also contains bisphenol A (aka BPA; that's the stuff that some plastics manufacturers have been using for nice clear baby bottles & drink bottles (e.g., Nalgene) and that Canada has banned in baby bottles. BPA can cause cancer and infertility.

Some marine varnishes--e.g., spar varnish--may be OK, but as Kriminaal stated, check carefully first. You don't want to put your beloved snake in something that will kill it!

what about that water based poly varnish will that do to seal it

[kriminaal]

You'll be fine with 3 or so coats of the poly.

There are epoxies that are safe. I use them. Be sure to do good research on what's available in your area. Just because something says "water-based" or "marine" means absolutely nothing.
Check out an MSDS list online to find out all the ingredients.
I talked directly with the manufacturer of the product I use to ensure that.
The benefit of using epoxy is being able to apply a single coat, compared to 3 or four needed for some polys.
The product I use can even be applied indoors with no virtually no odour.

Yes, I've just in the past few days heard that there are some safe ones for vivarium use. They are different from the ones used for industrial purposes.

It would be helpful if you'd give us the name of the one you use.

Whether you can smell something or not, toxic compounds can be outgassing as the epoxy cures. 1) Humans can't smell nearly as well as most other animals, snakes/reps included. 2) Not all toxic compounds have a detectable odor. Case in point: the natural gas piped into many homes for cooking & heating is odorless, so the gas companies add mercaptan, which smells like rotten eggs, to the gas so you can tell when there's a leak. So you should still apply epoxies, varnishes, etc. in a well-ventilated environment so that you don't poison yourself.

[kriminaal]

I'm not sure where it's all available. The one I use is called G-1 by Industrial Formulators. Note that they have a G-2 product as well that is NOT SAFE.
When I contacted them they said to cure it above 25 deg for a week. So I put a few heat lamps in to cure it.
This product is also used in aquariums.

Sorry I didn't mean to imply that no smell means a safe product.

[phil_7870]

well it going to be 4ft by3 ft by 2 ft and im planning on paint it black first and then putting poly varnish on it wat do you's think will it work aslo the ply is called shutter ply

[kriminaal]

Never heard of shutter ply. Note that the cheaper you go on the plywood, the more poly you'll need to put on.
Why bother painting over the black with poly?(not sure if it would react or not)

There is a line of childrens paint by Rustoleum called Painter's Touch. It is safe for enclosures. If you siliconed all the corners the paint would be enough to seal it.
