How to Fix Broken Glass? 

Items Required

1. Two-Part Epoxy
2. Acetone or Alcohol
3. Cleaning towel
4. Razor Blade

Step 1

Collect all the pieces of the broken glass.

If the glass is broken into several small pieces or some pieces are chipped then it isn’t worth trying to repair it.

The repair is likely to be successful if the glass has broken into two or three large pieces.

 

Step 2

Clean all the pieces with acetone or alcohol

After cleaning, wipe all pieces dry meticulously with a cleaning towel.

Pay special attention to the edges that you're going to glue together.

The pieces will bond best if they are clean, dry, and grease-free.

• Wear latex gloves or cotton gloves while preparing and gluing the surfaces. This will prevent oil from your hands from rubbing off on the glass, and protect you from toxic or messy adhesives.
• Difficult stains can be scrubbed off using steel wool.

Step 3

Mix clear two-part epoxy glue with the hardener that comes with it on a piece of scrap cardboard.

To get the strongest repair, use a product that takes longer than 5 minutes to set -- it will be less brittle than one that sets quickly. Mix only what you need for the repair -- you'll have to discard what you don't use.

Step 4

Spread the epoxy on the edges of one of the pieces of glass you need to glue, using a toothpick. You don't need to apply the glue to both surfaces of a joint, as long as you spread it evenly. Try not to leave voids, but don't use too much glue, or you may have trouble cleaning the glass after the glue sets.

Step 5

Press the two pieces together

Ensure the broken surfaces are aligned and hold in place for at least one or two minute.

Step 6

Allow the glue to set.

This will take somewhere between a few minutes and 24 hours depending on the type and brand of glue. Even once it seems firm, avoid applying significant force for 24 hours.

Step 7

Shave away any excess epoxy with a razor blade. Check in on the glass before it's done setting. Excess glue may have oozed out of the joint and begun to dry. Carefully shave away this excess glue with a razor blade and wipe the surrounding area clean.
