Legos are a fabulous building toy for children and the young-at-heart. No matter your age, you’re never too old to play with Legos. So, when you put together a masterpiece you want to preserve, you need the right adhesive to do it. There are tons of options on the market to seal and preserve your Legos, but you need to choose carefully.
So, can you use Mod Podge on legos? Yes! You can apply Mod Podge while buying your Lego set, or once it’s completed. You will need a small brush, Mod Podge, and patience. While Mod Podge may not be the strongest hold, it can definitely be used to glue Lego pieces together, or seal a completed set with a spray on option.
While Mod Podge is great for a wide array of decoupage projects, it may not be the best choice for Legos. You can try and brush on the Mod Podge while you are putting your pieces together, or you can also spray the completed set. In this article I also share some other adhesives more suited for Legos. Let’s read on!
How to Mod Podge Legos
Mod Podge has been a crafter’s favorite since 1967. It works beautifully on wood, fabrics, paper, plastic and other porous materials.
While some people report being able to use Mod Podge on their Lego creations, others have mixed results. But, this will depend on the type of formula used. So, it’s not advisable to use standard Mod Podge or ones intended for things like fabric or paper.
Many people also paint Lego figures with acrylic paint, and then seal them with Mod Podge. Since you are sealing paint, in this case Mod Podge will work great.
My favorite and top pick is always Arteza Acrylic Paints. They have so many different colors, and the quality is amazing! I usually use Arteza Paints for all my projects.
First, you will need a small applicator brush like this Mod Podge Brush, to apply the formula on the Lego piece. Depending on how many pieces you want to glue together, this step will require a lot of patience. If you want to apply Mod Podge once your Lego set is completed, then I recommend a spray on Mod Podge formula.
In each scenario, you will want to let the Mod Podge dry for at least 24 hours, before you move the Legos. Mod Podge can be used on practically every surface, but there are also other adhesives that can work on Legos as well. If you try to glue your Legos with Mod Podge, and see that they aren’t adhering, you may want to try another brand.
Since Legos are made out of a special type of plastic, it may be difficult for the Mod Podge formula to bind to it. This is not to say that it won’t work, but you should have a back-up plan in case it doesn’t. I personally love using Mod Podge on all my crafts, so its my go to sealer.
What Is the Best Glue to Use on Legos?
If you want to use something other than Mod Podge as the adhesive, there are a host of alternatives you can look into. The ones mentioned here come highly recommended by crafters everywhere. But, it will depend on how permanent you want the bond to hold.
Loctite Ultra Gel Control Super Glue
This super glue by Loctite is a reliable all-around adhesive perfect for permanent Lego sculptures. It dries quick and clear along with being water and shock-resistant. It comes in a convenient two-ounce bottle with a no-clog applicator.
Gorilla Super Glue Gel
Gorilla has a super glue formula that’s permanent and solid due to their inclusion of rubber particles. This gives it a thick consistency. Within 30 seconds it’s dry and it doesn’t run or drip. It’s resistant to water, shock and corrosion.
Rhino Heavy Duty Glue
Rhino’s Heavy Duty Rapidly Drying Glue provides a strong, permanent adhesion for a wide range of stubborn materials, including glass, brick and concrete. So, it will work like a dream with Legos. It forms a tight seal within seconds providing protection from falls, accidents and moisture.
How Do You Permanently Secure Legos?
Securing your Legos together permanently isn’t difficult, but it does take precision, forethought and some planning. Your first consideration will be the adhesive, making sure the blocks won’t lose their bond in any capacity.
Then, look at your structure and consider a way to glue it together without losing the design. Depending on the intricacy, you may have to draw out a diagram or take detailed photos so you can start from the base and work your way up. But, you will have to configure this according to your unique situation.
You may choose any of the recommended adhesives, or you can glue your Legos with Mod Podge.
Can You Unglue Legos?
As long as you use a semi-permanent or temporary adhesive, you’ll be able to unglue Legos fine. You may have to use a little soap and water to clean off the surface of the blocks. If you are using Mod Podge, or other permanent glues, the chances you can unglue your Legos are pretty low.
I recommend soaking them in really hot water, which may help melt the adhesive, but it’s not fully guaranteed it will work.
Does Acetone Melt Legos?
Acetone will melt Legos. Even if you use a small amount on a cotton swab, it will roughen the texture of the blocks. Therefore, apply acetone with caution.
Final Thoughts
Mod Podge might work on a Lego sculptured masterpiece, but it will depend on the kind that you get. It might be better to use it as a sealant for permanent bonds. If you’re looking for something temporary, it may not be strong enough. Even if it is, it will be difficult to remove any residues.
Regardless, some of the finishes and effects Mod Podge offers may give your work of art a panache you can’t get with glue alone. While it is a versatile substance for many crafts, it may not be ideal for Legos.
