If you have a cracked mirror that needs repairing, the first step should be thorough cleaning with glass cleaner and microfiber cloth to remove dirt, dust, debris, or broken pieces of glass and dispose of them safely. Next, apply a thin coat of clear nail polish over any cracks – this will protect both surfaces as well as stop the further spread of cracks; allow this solution to dry before using your mirror again.

DIY mirror repair methods offer a quick and inexpensive solution, yet may only temporarily repair a cracked mirror. Unfortunately, this DIY method may not work on all types of mirrors – for longer-term results consider hiring professional replacement services to install new mirrors in its place – before using tools such as screwdrivers and putty knives to remove existing ones and inserting new ones in their frames.

Before starting to apply the epoxy resin adhesive to a mirror, it is necessary to first prep it. Begin by cleaning its entire surface – especially its damaged areas – of any dirt and debris which might obstruct its adhesive process. You should wear gloves and safety goggles as protection from cuts or scratches. Also, select an area which offers ample lighting and ventilation where your work can proceed smoothly.

Before beginning to repair a mirror, place clear tape or aluminium foil over its backside to help support it while it is being worked on. Next, apply a thin coat of epoxy resin adhesive over any cracks – fill them completely by gently pressing edges together – allowing time for drying before trying to move or hang your mirror.

As another option to repair your cracked mirror, you could also try using strong glues such as super glue or epoxy. These adhesives have been developed specifically for glass surfaces and offer stronger bonds than nail polish or clear tape – however be mindful that using such substances may result in slight discolorations to the glass surface if applied incorrectly.

Sometimes mirrors crack and break without falling completely off of their wall, and when this occurs it should be possible to repair it using superglue. To begin this process, first remove any dust or debris from its surface before applying a small amount of glue directly over its cracked areas – be sure to spread evenly! After doing this, hold down both edges until it sets completely before letting go.

While this method will only repair minor cracks, it’s a smart idea if you can’t afford to replace your mirror. It’s straightforward and won’t cost a lot; additionally, it serves as an effective deterrent against children accessing expensive pieces of glass.

Before beginning, be certain you have the necessary supplies:

Use of a drop cloth or thick contractor bag.

Safety goggles. For your own protection and the sake of those around you, ensure your work space is free from hazards that could cause you to slip and fall. In addition, wear gloves when handling broken glass pieces as doing so could cause them to shatter further and damage both sink and floor surfaces.

Once your workspace is prepped, remove the stabilizer film from the epoxy resin. Apply adhesive directly to damaged areas using a plastic syringe from your kit – being sure that all surfaces of mirror are covered completely and there are no air bubbles!

Once the epoxy resin has set, you can begin peeling away its protective film slowly and carefully if you are having difficulty. Don’t force anything, as this could cause further cracks to form in your mirror if done too quickly.

Once the epoxy has been stripped off, use a putty knife to scrape away any adhesive residue on the walls. Be sure to wear gloves while using this tool, as it may become very abrasive and scratch the wall behind the mirror. Work from one end of the mirror towards its opposite so as not to scrape or scuff up its surface too much.


Glue can be an effective solution for cracked mirrors, but it’s crucial that the appropriate type is used. Super glue designed for glass surfaces such as mirrors is ideal; using this kind of glue should ensure that cracks won’t remain visible when dry. Nail polish is another viable option with clear glue-filled nail polish that may help stop further spreading of cracks; though this temporary fix may eventually return.

To permanently repair a crack in a wall, epoxy resin adhesive should be used. You’ll find this at most home improvement and hardware stores. Before starting, take precautions such as wearing protective eyewear and gloves so as to protect yourself from loose glass shards; and work in an airy place so as to not inhale fumes from working in close quarters with other people.

Start by cleaning the crack with a damp cloth to remove dirt or debris, using either a razor blade to scrape away stubborn residue, or an epoxy resin adhesive applied over both sides of the crack for easier access. Allow this adhesive to set for 24 hours before using your mirror again.

Nail polish can also be used to repair cracked mirrors, although its effectiveness may not compare to that of epoxy resin adhesive. In order to be effective, nail polish must be clear for maximum effect; use it only on smaller mirrors with only minor cracks and apply only small amounts to each crack – avoid applying too much as this will become difficult to remove later. Once dry, use a utility knife or putty knife to trim away excess nail polish from around your mirror frame.

Once the adhesive has set, apply a small drop of resin over the cracked area and allow it to set for another hour before peeling away the stabilizer film.

Cracked mirrors can be an eyesore and safety hazard. Luckily, there are DIY techniques you can use to quickly fix them and restore their shine – though please remember these solutions may only provide temporary fixes and may not work for larger cracks. As always when handling broken glass pieces it is recommended that all safety precautions be observed and gloves be worn for added protection.

Nail polish used for fixing cracked mirrors

Before applying clear nail polish to any cracks in your mirror, thoroughly clean them using a cloth or paper towel to ensure there are no broken pieces of glass in the cracks and remove dirt or debris. Next, evenly apply clear nail polish over each crack by carefully dotting in small dots; make sure not to apply too much polish at once and allow enough time for drying time (which could take hours depending on temperature and humidity levels). Finally, allow nail polish to completely set before leaving it sitting there to cure completely before moving on to other projects.

Another solution for fixing cracked mirrors is applying an epoxy resin adhesive layer. You can find this kind of glue at most hardware stores, and be sure to read and follow its directions before applying it on your mirror surface. As always, test small areas first before covering all surface areas with adhesive.

Once your mirror adhesive has dried completely, use a putty knife or clean cloth to gently smooth over any air bubbles or excess resin from its surface. After giving time for everything to set back into place, hang up your mirror again!

While it may be possible to repair a cracked mirror yourself, professional assistance may be required in some instances. If cracks are too large or vibration is extreme enough, replacement may be necessary – there are multiple solutions for doing this; find one which best fits your situation! Although cracking mirrors are a minor inconvenience, repairs could save some money by saving money from having to purchase another mirror entirely.
