BrickShield Plastic Adhesive Spray Glue - Temporary Glue Spray Adhesive for Bricks, Blocks and Multipurpose - Ideal Spray for Crafts, lego - Net Wt 2.5 oz - Non-Toxic Made in USA

I bought this because I watched my nephew take hours to put together various Star Wars Lego sets and then as soon as he played with them, they would fall apart... so the Legos became more of a "build it and put it on a shelf" than "build it and play with it" sort of toy. First use was last night and he built a plane. We sprayed it on according to the instructions, waiting for a few hours, and he started playing with it. Of course, he got a little too excited and dropped his newest creation. On the way down, you could see the horror in his eyes, and then when his plane hit the floor and remained in one piece, he was ecstatic... as was I. We may have to buy this by the case!

bought the BrickShield Plastic Adhesive Spray Glue to help my kids keep their Lego creations intact during playtime—and it’s been a game changer! The spray goes on evenly, dries quickly, and holds the bricks together just enough to prevent accidental collapses. What I love most is that it’s temporary—just rinse with warm water and the pieces come apart cleanly. No sticky residue, no damage to the bricks. ✅ Pros: • Non-toxic and safe for kids • Easy to apply and remove • Great for Lego, crafts, and small block projects • Made in the USA (love supporting small businesses!) ⚠️ Cons: • The 2.5 oz size runs out fast if you're working on larger builds • Slight odor during application (but fades quickly) Overall, it’s a fantastic solution for temporary bonding—especially for parents, hobbyists, or anyone who wants to preserve a build without making it permanent. I’ll definitely be grabbing the 3-pack next time!

Its terrible. Water thin and runs right off. Didnt work at all

Update review - so after using more than the “little goes a long way” as it recommends and letting it dry for at least 2 days, the glue actually set and works decent. So it works better than originally reviewed. This did not work at all. Sprayed the legos and all it did was leave a sticky film on the legos that needed to be washed off. The legos themselves did not stick together at all.

Easy to use. Testing the hold now, fingers crossed it works as well as expected. I didn’t read the content size and expected a spray paint sized bottle. The 4” bottle was a surprise.

Very useful.

Works great

Brilliant! As you can see, from my pictures, my son tested this glue with great results. My son said that the glue was easy to spray on, dried relatively quickly, and the glue got stronger over time. It does take up to 5+ hours for the full strength of the spray adhesive to work. When you are finished just rinse with warm water for a bit and your Legos are ready to build a new project. He prefers the aerosol over other glues since it is much faster to apply and it covers all of the legos. Impressively clear too. As a test of the glue's strength, he glued two bricks together and tried to separate them. It was INSANE. I couldn’t even get them to separate with my hands. Granted he did use a lot of spray for this test. Finally, had to resort to using warm water to get them to separate. Such a simple product but would make a great gift for any Lego lover.

Los legos van atrapando todo el polvo, se queda pegado y no se puede sacudir.

So it makes your lego sticky, leaves a bit of a film on it and worst part was it didn't actually hold it together well. It at most is good for if you are building big projects and want to steady it down to walk away for it for a while or to keep a bit of extra hold in the centre. I'm a mom I bought this thinking my son could handle the lego pieces after I was wrong.

Very sticky not good

Not worth the time or money. doesn't hold lego together, just makes it sticky.

Should have listened to the reviews that said it does not work with lego! I tried a full bottle on a lego project i had and it really did not make any difference!! It really has very weak binding effect on plastic and lego! Good i bought only one to try! Although it is not cheap!!!!!
