I need to bond some LEGOs together on my layout? Which cement/adhesive will work best??
Are LEGOs ABS plastic, styrene or something else?
Thank you for the help.

Kragle
See Lego Movie (krazy glue)
Use Crazy Glue in a small tube, and just put the glue on the dimples of the brick that way you do not have glue showing on your Lego bricks.
Isn't that like asking which pen to do the New York Time Sunday Crossword?
Bill,
I would get some Plasticweld cement from Plastruct. Dab some onto a Leggo block and rub the glue across the surface to see if it digs in. If it does, I would use this type of glue. If it does not dig in, use crazy glue.

I second the Kragle. (Krazy Glue).
You need very little, around the sides of the 'dimples' or 'bumps', not on top of them. Lego (the actual name brand ones) tend to stay together very well, but I have used very small amounts of Krazy Glue with long term success in the suspension parts of a rather large tractor-trailer model I built some years ago, where the weight of the model otherwise separated the pieces.

I forget what the Lego model builders use to build their display pieces, but I think it is a thin liquid like the Plasticweld that Alan suggested. Testor's liquid cement should also work. If you can get a syringe, it works really well for dispensing the liquid along the seams. CA type (Crazy Glue) may work for Hollywood, but can leave an ugly white residue if you get it on an area that can be seen.
I tried Bondene (label says for ABS and styrene) but with no effect. Krazy glue worked well. Next up, Plasticweld.
Well, I guess I'd ask one more question before making a recommendation....
What kind of stress(es) will your Lego assembly being subjected to, for which you feel some bonding is necessary?
The reason I ask is that a simple tacky glue...like Aileen's brand...used sparingly will often do a sufficient job holding parts that are otherwise designed to be taken apart and reassembled......like Plasticville structures, for example.
I know some areas of the country are subjected to earth-moving forces. Multiple metal straps are required by code to keep the ol' water heater tank from toppling, for instance. Model railroads, in my septuagenarian experience, do not usually require Draconian measures to keep things in their place.....unless of course they're frequently moved for shows/display, relocation moves, seasonal storage, etc
An example of tacky glue effectiveness we (LHS) have used is in keeping the small Fastrack switch lanterns from flying off their mounts on the four switches wired for automatic route control when the train runs for customers. As the old Wildroot Cream-oil Hair Tonic ad once promised....'A little dab will do ya!'...so it's been for the lanterns. A couple dots of tacky glue has held them in place for years.
Well, it's just another thought......FWIW.

Remember, it's LEGO, not Lego. They are ABS. And most importantly, it's blasphemy to glue the little colorful plastic bricks together!!
Showing my age, I thought it was Brylcream that used " Alittle dab will do ya'" ? I think it is vital that we get clarification on this before we proceed. Ether way, I can't seem to find my Wild Root or Brylcream anywhere these days.
ONLY USE THE KRAGLE!!!!
I have seveal lego buildings that I take to shows for display with my o gauge trains and even some railcars built out of lego and mounted on mpc era trucks. I have never needed to use glue.
LOL!!! Is this a trick question? Kragle of course.
I have never thought of using lego blocks.But I think I will get a few blocks.And use as bridge supporters for a bridge.Some of them look like concrete blocks anyway.
A couple of years ago John Sethian shared a way to create Pennsy stone block walls out of LEGOs and joint compound and a little paint. The process is simple and the results were magnificent.. I will see if I can post a picture.
The technique was in one of the quarterly mailings from MTH . Pictures of his walls appear periodically as he shares layout photos.

That would be cool to see!
