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

My neice had a lego that wouldn't stay together and I got some more of this and worked wonderfully like always.

Definitely not worth purchasing! Barely sprayed a few of my sons legos because of how small can was. Left my hands and legos super sticky with a chunky finish on legos even after drying even after reading the directions carefully on how to apply. After allowing to dry for over a week I went to go see how strong the hold was and the legos came right apart with me barely pulling them. Purchased for my son who wanted to protect his legos from smaller kids who visited and definitely made no difference. Was better off never buying if anything ruined his legos with chunky finish for no point because it did NOT even stick.

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.

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.

I used this glue spray to secure a LEGO Art piece that I have no intention of ever disassembling, and wanted to protect it against accidental disassembly, (falling of the wall, bumps while moving, etc.)If you want to safely keep your brick builds intact, this product will function suitably, so long as you keep some things in mind.- A light spritzing is not enough for a truly secure bond. A more liberal application will result in a much firmer hold.- Drying times for the glue to completely set are much more than just a couple of hours, if you use more than just a very light spray.- Do not touch any sprayed bricks until you are confident that the glue has set, otherwise you could induce smudges that will become far more visually apparent.- Though clear, there can be some visible residue left after drying is complete. Depending on the color/shape of bricks being used, this may or may not be obviously present. I used the glue on the LEGO Art set The Great Wave [off Kanagawa] and only noticed the residue on the completely flat, and white tiles that made up the exterior matte between the actual work, and the frame. On the individual bricks that the work consists of, no residue was noticeable.Overall I’m quite happy with this product. I have no intention of ever disassembling this LEGO set, and as it’s a permanent installation, I wanted to ensure it’s longevity. For that purpose, this glue spray seems to be a success.

Super easy to use and washes off great. This is a great glue to help hold things together, but is not as strong as super glue. I'm glad there is something between super glue and nothing. Make sure you shake up the can really well. The first time I sprayed it it looks like it wasn't mixed enough and not a lot of the glue came out. Shaking if for a good 30 seconds helped.

Can is so small couldn’t even cover half of this 12” homemade nutcracker can felt empty when I got it.

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!
