Glueing up 2 18mm pieces of plywood
Hello, looking to glue some 600 x 550 ish bits of plywood together. I have googled it but some say don't use wood glue as the moisture will get sucked out and the bits will warp. Others have said use contact adhesive, one said use spray adhesive (easier than contact but similar principle) I don't mind what I use I think contact or spray would do the trick? It is for a drill press table. Nothing flash but I don't want warpage. Not a real word apparently, should be!
Thanks,
Jeff

I'm assuming you want to glue them up to end up having one 600x550x36mm thick panel...
you can use polyurethane glue... it foams up and provides quite good bond.. and you don't have to cover the whole surface (thanks to foaming..it expands) just put several streaks 20 -40 mm apart.. staying away from the edges (so it doesn't foam outside... it is just bit unnecessary mess you need to clean up afterwards).. clamp it and leave it to dry.. I usually leave my glue jobs for at least 24 hrs.. I plan my work to do the glue up last thing leaving it to dry overnight...
Done several pieces like that and there was definitely no warping altogether...

If you must glue it the some good old Selleys Aquadhere (white glue) will suffice along with screwing it together or just dry screw it together and forget the glue.

Thanks. Yes I wish to make a 36mm top. I'll try to find some polyeurethane here in Canberra. I do have some aquadhere Rod and some Triton wood glue.

Bunnings sells foaming PU. Masters has all the titebonds. TB1 is fine for your application.
Spread it on, sprinkle some rock salt around so it doesn't slide then clamp/brick/training weights to hold it together.

Warpage is not listed in the Cambridge or Oxford dictionaries. However it is listed in Dictionary.com and Webster's dictionary as a noun.
Anyway if I mention the annoying warpage of my board last week, then at least 2 people have used it in published writing. Does that then make it a real word?

Oh don't get me started....
If you use it it is a word. Dictionaries are not prescriptive they are descriptive. Words are added to the language all of the time by people using them.
Language is for communication and if you communicate your meaning then your job is done.

I've used titebond and screws for gluing plywood together before. No dramas.

If you glue and position and weigh down or clamp to dry so it is not warped it won't or should'nt wrap when dry.
