Breaking a mirror has got to be one of the most heartbreaking moments in life.

There’s bad luck involved, but most importantly, how will you repair the glass?

That’s what I’m about to present in this article – the best glues for fixing mirrors.

Stitch a mirror back together may seem impossible, but it’s not. With the right adhesive, a broken mirror is nothing but a fixable object.

You can even mount mirrors on the wall using these adhesives.

Next, I’ll talk about the eight best glue for mirrors, a buying guide, and the type of mirrors you can repair with these glues!

Types of Glue for Mirrors

There are multiple types of glue for repairing or mounting mirrors. You’ll find the one you need among these types:

Liquid nails

Liquid Nails are great if you need to fill gaps in a broken glass because this type of adhesive expands outwards.

Even though it takes a while to dry, liquid nail glues are a great choice for many occasions.

However, most are toxic, so I recommend wearing a face mask during the application.

Urethane

Urethane adhesives are industrial-grade glues that are good for small-scale and large-scale applications.

Most types of urethanes are toxic and not resistant to extreme changes in temperature, especially high temperatures.

Silicon adhesive for mirrors

Everyday mirror glue for common broken-mirror situations, that’s your silicone adhesive.

It only works on small surfaces, but the bonding strength is more than worth it. It’s also highly resistant to high heat and low temperatures.

Glues that don’t work on mirrors include regular gorilla, epoxy, wood, hot, and silicone.

Best Glue for Mirrors: The List

Below you can find my list of the best glue for mirrors.

1. Permatex Clear RTV Silicone Adhesive Sealant for Mirrors

First, on this list, the Permatex Clear RTV Silicone Adhesive works on all kinds of mirrors, snow globes, and more.

Its high tensile strength elasticity allows for easy application and a long-lasting bond.

Once you repair the mirror with Permatex, you can be sure it won’t break apart again.

Thanks to its waterproof concept, the glue ensures additional protection against water hazards, and the lifespan of the mirror improves again.

The one disadvantage is that the drying process takes longer to finish. Also, some types of Permatex may have a foul smell.

This product is also great if you need glue for glass.

2. Loctite Construction Mirror Adhesive

An efficient glue that works on most mirror types, Loctite Construction Adhesive is an industrial-grade glue for glass.

The formula is water-resistant and durable, with plenty of protection against heat and solvents.

High temperatures won’t harden the glue, so it’ll keep its elasticity and durability over time.

Moreover, Loctite works on marble and granite, so construction projects are good with this adhesive.

Despite a long time it takes to dry, Loctite Construction Mirror Adhesive maintains a super-strong bond.

However, you may make a mess when using it because of the glue texture. Its odor is also unpleasant.

Finally, some variants of this glue may contain toxic chemicals, so I recommend wearing gloves and a face mask when working with it.

3. Liquid Nail Adhesive

For some mirror types, Liquid Nail Adhesive is one of the best glues you’ll find.

That’s because the tensile strength is very high, and the bond is very durable.

From tests, I discovered that Liquid Nail Adhesive is best used to fix mirrors on the wall.

In terms of durability, this glue is highly resistant to high temperatures and completely waterproof.

While the drying process takes 19 minutes, the curing process is faster.

However, I recommend waiting 24 hours before attaching the mirror to the wall to be safe.

Liquid Nail Adhesive smells pretty bad, so I recommend wearing a respirator when working with it.

It’s also not very good for joining pairs of glass surfaces together.

4. Gorilla Heavy Duty Construction Adhesive

Waterproof, weatherproof, and highly resistant against heat, Gorilla Construction Adhesive is an industrial-grade glue for mounting mirrors on vertical surfaces.

It bonds quickly with most known materials, including metal, plastic, wood, and more.

In 30 seconds after application, the glue will grab hold of the materials and dry in a few minutes.

I recommend it for most mirror mounting applications because you won’t need to clamp it down.

However, the glue may arrive dried up upon purchase. It also doesn’t have a long shelf-life, so you’ll need to use it quickly.

5. Loctite Power Grab Express All-Purpose Construction Adhesive

This all-purpose Loctite adhesive works on many materials, including wood, plastic, tiles, metal, ceramics, glass, and more.

It’s a construction-grade material, so its tensile strength and durability are higher.

I recommend it for indoor use because it bonds fast and it’s very easy to use.

As for hazard resistance, Loctite Power Grab isn’t ideal. That’s why you shouldn’t use it outdoors.

The substance is very thin and runny, so it’s easy to work with it. Once it dries, the glue becomes rock solid and keeps everything intact, especially mirrors.

Loctite Power Grab is a great choice whether you’re repairing or mounting mirrors.

6. Gorilla Clear Glue

Super Glue is the last line of defense for mirror repairs. Gorilla Clear Glue is best used for porous materials such as glass, plastic, and metal.

It produces a super-strong bond that’s waterproof and heat-resistant.

The drying process takes a long while, and you’ll need to clamp the materials for 2 hours.

The curing process will take another 24 hours, but the bond is secure and shock-resistant once it’s finished.

Lastly, once dry, the glue appears clear so that it won’t interfere too much with the mirror’s reflection.

Gorilla Clear Glue is also perfect as glue for marble.

7. Gorilla White 100 Percent Silicone Sealant

This silicone sealant from Gorilla is a great adhesive for vertical mirror applications, thanks to its durable and high-tensile bond.

After application, it’ll take 30 minutes to dry and cure, making it ideal for plumbing, gutters, windows, mirrors, doors, bath, and kitchen applications.

Once dry, the glue is translucent, waterproof, and weatherproof, which means it’s great for indoor and outdoor applications.

It also makes for a great sealant for specific applications.

However, Gorilla White isn’t exactly an adhesive but a sealant. Still, it’ll do its job without a hitch.

8. Gorilla Heavy Duty Spray Adhesive

The only spray-type glue on our list, Gorilla Spray Adhesive, is incredibly easy to use.

Upon application, it disperses a fine mist of glue that hardens in about 10 minutes. So, you can reposition your materials during that period.

Once dry, the bond becomes waterproof and virtually unbreakable, which is ideal for glass.

Moreover, Gorilla Heavy Duty Spray Adhesive has the potential to bond most known materials, including metal, wood, glass, leather, paper, fabrics, plastic, and more.

While the application can be messy if you’re not careful, it becomes clear once dry and won’t yellow in time.

Glues For Different Mirror Types

There isn’t just one type of mirror out there. Similarly, not all glues work for all mirror types. This should help you:

• Glass mirrors – To bond two pieces of glass together that aren’t curved, you’ll need a cyanoacrylate. If the materials are curved, use an epoxy resin, as cyanoacrylates can’t form airtight bends around the curves.
• Rearview mirrors – If your rear-view mirrors are cracked, I recommend cyanoacrylate glue. It’s the simplest fix for small and narrow cracks on glass.
• Attaching mirror to wood – Contact adhesive works best for this application. It won’t leave any residue and won’t affect the paint on the wall. Don’t put too much glue on the wall, though.
• Mirrors with metal frames – This is where epoxy resin glue comes in handy. It forms an airtight seal around the mirror’s edges and prevents moisture from piling up. Work with it carefully, though. It’s toxic and very sticky!

The list above contains glues for every type of mirror I talked about, so you’ll find something that works eventually.

Mirror Glue Buying Guide

You should consider a few things when buying glue for repairing or mounting a mirror.

Not every glue is right for the job. Let’s see what you should take into consideration when buying mirror glues:

• Drying time – How long does it take for the glue to dry? Generally, the faster it bonds, the better. You’ll also need to support the mirror when mounting it on the wall until the glue dries completely.
• Adhesive vs. Glue – There’s a difference between glue and adhesive. When repairing a mirror, you’ll need glue that dries clearly, but a durable construction adhesive is better for mirror mounting.
• Materials – The material you’ll use the glue for is also important. Porous materials and non-porous materials work with different types of glue.
• Color – Mirror repairs need adhesives that dry clearly, for obvious reasons. If you’re mounting a mirror on the wall, the color of the glue is irrelevant.
• Water and heat resistance – Lastly, you want an adhesive resistant to both water and heat. This provides more durability to the bond, increasing the mirror’s lifespan.

Don’t rush to buy any glue for any occasion. Mirror mounting and repair require more than just silicone adhesive.

Think about the material, environment, and type of application you need before choosing glue.

Conclusion

There’s no reason to fret over a broken mirror. Repairing the right adhesive won’t take more than a few hours.

No need to call a specialist when you can become one right away.
