Dirt, dust, and debris can affect how well the resin fills the crack, so be sure to clean the area well! Remove any loose fragments of glass from the crack.
Don’t peel off the adhesive backing until you’re ready to apply the film. Be careful not to allow the film to stick to itself or it may no longer be effective.
Avoid removing the film and reapplying it or it could affect how well it adheres and leave behind a sticky residue.
Make sure there aren’t any creases or bubbles in the film.
You may need to cut the tip of the syringe with a pair of scissors in order to use it. If the resin did not come with a syringe, you can find one at an auto supply store, department store, or online.
The tip of the syringe should be inside of the crack.
Add a small amount of resin at a time. If you apply too much too quickly it could form an uneven bulge under the film.
Check the packaging of the resin adhesive for specific drying times. Set an alarm on your phone or clock for 20 minutes.
Don’t use quick or jerky movements or you could tear off a section of the film. Use a razor blade to get underneath the film if you can’t peel it off with your fingertips.
Use your fingers or a razor blade to smooth out the curing film and remove any bubbles from beneath it.
Check the packaging of the resin for the specific curing time. Aim a fan at the mirror to help it cure faster. Set an alarm for an hour so you can be sure when the resin is done curing.
Be careful not to scratch the resin of the glass of the mirror. Angle the razor blade or utility knife so it’s parallel with the surface to run it over the crack evenly.
Don’t saturate the mirror with glass cleaner. You can find glass cleaner at department stores and online.
