Is plywood OK to build an enclosure with?

Just wanted to check if it would be a bad idea to use normal plywood from Lowes/Home Depot to build an enclosure with.

Care sheet http://ball-pythons.net/forums/showt...s%29-Caresheet says not to use pine or cedar for substrate. Not sure what plywood is made out of really.

No i would not. Unless you take the time to seal everything really well. But that could be a PITA and expose your snake to chemicals if you dont do it correctly. Plywood is just chips of wood held together with glue so it molds and decomposes very easily.

What would a good material be? I'm looking to do it cheap, but safe. Also I was referring to plywood, which is sheets of glued together wood. Not to be confused with particle board which is the chips and stuff all glued together. Point taken though.

Plywood is still chips or shreds of wood glued together into layers. Particle board is small pieces or particles of wood glued together, just not in sheets. Particle board is heavier and more dense. Melamine is alot like particle board except is has the plastic sheets or coating on the sides. And then theres plastic strips you can use to cover the edges. Melamine would be better to use since it has that coating. And then I would cover the base/floor with vinal tiles or something. And then coat the seams with aquarium sealant and coat the whole inside with epoxy or something. Im not sure what type of epoxy would be best to use though.

So does the melamine contain toxic chemicals? Is sealing the sides just an appearance thing, or do we really want to seal up all traces of what's inside the plasitc coating?

i built my enclosure out of plywood and used laminate wood board to cover the plywood for easy cleaning but i saw that it couldn't keep humidity good.

i no longer use it anymore i built a snake rack which personaly i think is better.

No melamine is fine bc people use it for racks. I misspoke in my last post, i apologize. If you build it out of melamine i would just seal all the seams with aquarium sealant and you should be all set. What do you plan to keep in it?

Check around for plastics manufacturers in your area, and you just may find one that has expanded PVC board available. This is an ideal material for making a reptile enclosure, IMO. It's not dramatically expensive, either.
You can cut and work it just like wood.

Also, I would seal a mealmine cage very, very well, because although it is used for racks, it is NOT risk-free. Most melamine board is a particle board covered with melamine, and the particle board is often held together with a glue containing formaldehyde. Formaldehyde-free melamine is avaiable, but more expensive, and is very hard to find.

Melamine (the particle board substrate) is actually quite toxic. It has formaldehyde and urea glues used in MDF and particle boards. Most plywood is glued with similar phenolic resin glues that once catyalized have less out gassing also the glue joint is very small only the very slight edge where particle board the joint is the full exposed width.

The shop I used to work in particle board and MDF required a use of a respirator to work with it.

I would expect plywood to be far less toxic than particle boards especially looking at the MSDS sheets for various products. Any bare wood needs to be sealed in any case. I would not use cedar ply but the fir (douglas or spruce usually) is fine and pine is fine if it is kiln dried (all ply is) but if asked I would really use either plastic or birch ply it is 1000 times easier to work with (flatter and less voids fill spots ect...) and seriously stronger.

melamine is used usually because it is cheap.

Im not questioning you, thanks for the info actually i ha no idea, but then how do tons of people use melamine racks successfully?

So how is MDF and melamine, etc harmful? I get the dust paritcles when cutting and sanding, but what about after construction, how does it harm the snake? Just sort of curious at this point.

Voodoo,
Melamine board, as I mentioned, is usually made with a glue containing formaldehyde.

Formaldehyde outgasses from the particle board, and does so particularly badly when it is heated. It's toxic and carcinogenic.

MDF is a problem for the same reason.

The problem can be reduced by heating and airing out the board in advance of using it, (by drying it in the sun for a week, for example), and by sealing it extremely well, but it's not risk-free. There are safer materials to use.

I don't have answers as to how much out gassing of formaldehyde or other gasses effects snakes. The information I have is how it effects humans. The assumption is it has some effect but what? hard to say.

There are so many things and variables that it is impossible to say if or how much. I feel I have a responsibility to bring as much information as I have to the table. It is the op job to weigh and make an informed decision. I work with chemicals everyday (formaldehyde is one) and what you don't know WILL hurt you. Chemicals can be used safely but only if you know what safe is.

Personally I feel quite confident in saying any and all wood products should be sealed before long term (snakey) contact. That includes all ply woods and all particle woods including the exposed edge of melamine board. This is simply prudent nothing more. Lots use melamine lots use MDF. (we always called it medium death board) does it effect the snakes? maybe. The best answer anyone can give there are no studies been done I know of. Does it effect the person using it? YES that is well documented. The best answer I can give. For humans plywood is less harmful than particulate boards (chip, particle and MDF)

Thanks kitedemon, that sums it up quite nicely.

However I will add that level of exposure has to be a huge factor here. Just because you have a melamine shelf in your house doesn't mean you are inhaling dangerous formaldehyde levels and going to get cancer.

I look at it like this, take gasoline for instance. It has high levels of benzine which is horribly carcinogenic. Would I want to drink water from a well downhill from a gas station, uh no, but I also don't wear a respirator and hazmat suit to fill up my tank.

So the risks aside, what is the best way to mitigate things? Folks mention sealing the wood. What is a good sealer? Are we talking like shellac here or what?

*Disclaimer: The above is my 2 cents. I'm a computer engineer, not a chemist or human health expert so what do I really know.

Vdoc that is completely true amount , type frequence, a handfull of other variables all effect how bad the exposure is.

sealers are varied as well. I don't think shellac would be a good choice alone anyway as an primer sure.

The toughest is likely marine epoxy very expesive and liner polyurethanes would be next but also super expensive.

A good polyurethane paint or varnish is fine as long as it is FULLY cured (4-5 days and I'd expose it to 80-100ºF temps for 12 hours if I could.) i really like colors in plastic by varathane personally.

Any oil paint will do just avoid paints made for decks and bathrooms (often have biocide additives) and anything that says SPAR on it. Spar (sailboat booms and masts are spars) varnish or paints they are designed to be flexible and never fully cure.

Water based products are fine too (again not ones ment for decks or bathrooms) I would use exterior as the humidity can be quite high. I find water based ones to no be as hard wearing myself but they work just fine.

Oil finishes I'd probably avoid all together.

My granddad used to use a polished pariffin wax finish that is not toxic and waterproof it would likely work well too. Most finishes will be fine. For the most part cured paint and varnishes are plastic. There are no thinners or other things left (bathroom and decks excluded) Floor paint is nasty smelling are hard to deal with so I'd not just for that reason.

The range there, epoxy and LPs are very difficult to use so if you have no experience with them stay away from it. I hope this helps.

I have built several enclosures out of plywood. I used water based stain and the a water based polyurethane to seal them. I have been using these enclosures for several years with no problems. You will need to let it air out after sealing with your heat tape running until you cant smell it anymore which took over a week for me.

Great point Jason i should have mentioned. smell the paint, (walk in from fresh air and immediately smell) if it smells of paint it is not fully cured if it doesn't smell of much it is.
