How to Fix a Broken Mirror makes a room look more rundown than a broken mirror with cracks spiderwebbing across its surface. Besides poor aesthetics, it’s also considered bad luck in some cultures to have a ruined looking glass. The good news is that fixing a broken mirror often turns out simpler than you’d think. We’ll discuss various options for repairing and replacing the following.

How to Fix a Broken Mirror

Thoroughly Assessing Damage and Repair Options

Before tackling any broken mirror repairs, you first need to thoroughly examine the break and determine if it’s salvageable or needs replacement. Carefully gather up all glass shards – even tiny slivers – wearing thick leather gloves to avoid cuts.

Lay out the pieces on a protected surface like a towel atop a piece of cardboard to analyze

  • Location and size of cracks/shatters
  • Whether mirror backing/frame is still usable
  • If broken shards can realistically be puzzled back together
  • Where the unfinished edges may be located if replacing

Tip: Number each shard with a marker to map placement when reassembling.

Types of mirror glass like acrylic vs real glass impact how repairable damage may be. Here is a breakdown of what kinds crack most easily

Mirror Glass TypeDescriptionCrack Pattern When Breaks           Difficulty of Repair
AcrylicMade of flexible plastic Spiderwebs across pane but pieces hold togetherEasiest
Plate GlassMost economical float glass   Large, jagged shards split apart        Hard
Tempered GlassHeat-treated for strengthShatter into tiny cube pieces if triggeredNearly impossible

If your break isn’t too severe – just chips along the edges or a single crack across the surface – simple DIY resin repairs often do the trick. A few options.

Mirror Repair Resin

  • GlassWelder, Loctite, Kintsugi brands
  • Inject into cracks via syringe
  • Dries clear in sunlight

But if there are large missing chunks or the whole mirror collapsed into piles of shards, replacement is likely needed. When assessing, consider

Where’s unfinished edge?

  • Wall side – replace whole mirror
  • Frame side – insert new pane

Calling in professionals for tricky wall-mounted and unusually sized mirror installations is also often wise.

Quick Tabletop Edge Chip Repairs

For minor edge and corner chips on tabletop vanity mirrors or decorative wall mirrors, you can achieve quick fixes with common household items.

Clear Nail Polish

Use the tiny brush to precisely fill missing shards smoothed back into place along frame. Allow 12 hours to fully cure and strengthen bonds before handling.

Tip: Apply diagonal strokes overlapping the glass edge for a smooth fill.

Super Glue

Carefully dab gel formula along broken edges using a toothpick for control. Clamp cracked corners with binder clips pulled tight. Give at least 30 minutes to an hour to set.

Colored Markers

For stable but now exposed unfinished glass edges, simply color the seam to blend with your frame finish.

Restoring Large, Shattered Wall Mirrors

Trying to solidly re-adhere all the shards of an exploded decorative mirror is ambitious but not impossible. Follow these tips when tackling the rebuilding process.

Step 1) Thoroughly Clean All Pieces

  • Handle shards by edges only
  • Gently scrub both sides removing grime
  • Rinse and dry each piece

Step 2) Map Out Placement

  • Start shards with most defined corners
  • Create rows using painter’s tape
  • Photograph progress

Step 3) Mix 2-Part Epoxy Resin

  • Clear 5 or 30-minute formulas
  • Slowly stir avoiding bubbles
  • Use popsicle sticks to apply

Step 4) Affix Shards to Backer

  • Begin at eye level in sections
  • Apply thin layer across each piece
  • Use binder clips to hold until cured

Once fully restored, protect the surface but also reinforce the frame with corner gussets before rehanging any intricate puzzle-pieced mirrors.

Step 1) Prepare Wall

  • Fill/sand uneven surfaces
  • Ensure surface is clean

Step 2) Attach Mounting System

  • Adhesive mirror mounts
  • Concealed French cleat
  • Mirror clips

Step 3) Insert Mirrored Glass

  • 1/4″ tempered safety pane
  • Apply waterproof sealant
  • Check alignments

Step 4) Seal Edges

  • Transparent silicone
  • Decorative trim moulding
  • Leave 1/8″ gap between wall

This finishing touch contains the edges while allowing the mirrored glass to flex minimally when opening/closing the cabinet without cracking.
