In the case of a cracked mirror, it is important to first start by cleaning it. You need to make sure that there are no stains on the mirror. The cracked mirror can be easily cleaned with the help of a microfiber cotton towel. The cotton towel will help remove any dust particles from the cracked mirror and make it look clean. If any broken pieces have fallen from the cracked mirror, you can just trash them.

You cannot clean the mirror just by simply wiping it off with the help of a cotton towel. You must use a mirror cleaner as well. If you do not have a mirror cleaner, you can simply make one at home. All you have to do is to mix vinegar, dish soap, and water.

2. Put a Stabilizer Film

Once you are done cleaning the cracked mirror properly, you must apply a stabilizer film to it. You need to start by removing all the contents of the mirror repairing kit that you have made for the job. To apply the stabilizer film, you must remove the adhesive back it has.

Make sure you peel off its back properly so that it can be applied to the cracked mirror without any hassle. Sometimes, it can be really difficult to remove the adhesive back of a stabilizer film because it is too sticky. When done with removing the adhesive back, you need to put the stabilizer film onto the cracked mirror carefully.

3. Apply Resin

After you have put a stabilizer film, it is time to apply the resin on the cracked mirror to help fix it. The resin comes with a syringe to make the application more convenient for you.

If you want to apply the resin nicely, it is important that you first touch the edge of the stabilizer film and lift it slightly. It is time to nudge the same edge underneath the stabilizer film when you are done doing this.

You must repeat this procedure for any cracked areas that you see in the mirror. This way, the cracked mirror areas will have a layer of resin. You also need to firmly press the top of the stabilizer film to help the resin layer set into the cracks.

4. Let it set

Once you are done with applying a layer of resin into the cracks, you must give it enough time to set. Yes, you read that correctly. The resin takes at least 40 minutes or so. You can also set a timer for this purpose if you want. The resin will become hard once it has dried properly. This is also one way of telling that the resin has dried properly.

5. Remove the Stabilizer Film

Now that the resin has dried, it is time to peel off the stabilizer film. First, you need to touch the resin surface with your hands to make sure that it has dried properly and nothing is sticking to your hands.

When you are sure about it, just remove the stabilizer film. You can do it with the help of a knife as well if it does not come off on its own. Just make sure that you do it all in one go. The stabilizer film could still be sticky.

6. Remove the Excess Resin

Next up, you would be required to scrape off any excess resin that there might be on the cracked mirror. To be able to smoothly do the job, you must scrape the excess resin while wearing a pair of gloves.

The gloves will keep your fingers protected during the entire task. You can also use a razor blade to scrape off the resin from the cracked mirror. Again, make sure you do this step while taking all the precautionary measures and not harming yourself or cracking the mirror more.

7. Thoroughly Clean the Mirror Again

The last step is to clean the mirror again. You have taken so many steps to fix the cracked mirror. This means that you have touched the cracked mirror multiple times, causing stains.

The stabilizer film and the resin might have also left a few marks here or there on the cracked mirror. To get rid of those marks, it is important to clean the mirror thoroughly.
