How to Smooth Chipped Glass Step-by-Step Guide

Ouch! We know the feeling—a broken glassware item is never fun. So how to smooth chipped glass becomes the next important thing to understand.

 But don’t be too hasty to relegate your favorite mug or bowl to the trash can.

The key is smoothing the edges of the chipped-away pieces of glass, so there aren’t any sharp edges that could hurt you.

Plus, for those feeling extra adventurous, we’ll let you in on a few tips and tricks for adding a bit of flair to your newly refurbished glassware piece.

Safety Considerations When Working With Chipped Glass

When working with chipped glass, safety is always the foremost concern. First, ensure that any broken glass shards are properly removed. Wear thick gloves and glasses to protect your hands and eyes.

Have a first-aid kit handy in case of any accidents.

Make sure there are no flammable objects in the vicinity, and if possible, work on a flat surface to prevent any further damage due to slipping or accidental knocking over of your tools.

Once you have ensured that you’re working in a safe space, carefully wipe away dust from the chipped area with a damp cloth before attempting to smooth the chip with sandpaper or a diamond abrasive disk.

It’s also important to avoid using strong solvents on the chip, as these can further damage you and the glass.

Preparing the Surface of the Chipped Glass

Before you start to smooth the chipped glass, it’s important to prepare the surface to make working with it easier. Here are the steps:

Clean the surface – Start by using a clean cloth to remove any dirt and grime from the surface of the glass.

Sand it down – Use medium-grit sandpaper (120-180) to lightly sand down any rough edges or chips on the glass. Ensure not to over-sand or press too hard on this step, as it may cause further damage.

Clean off residue – Once you’ve finished sanding, wipe away any residual dust from the glass with a clean cloth or soft paper towel.

Use a mild soap solution – Now, use a mild soap solution and a clean cloth to give the glass one final wipe-down before starting work on smoothing it down.

By properly preparing your chipped glass’s surface, you’ll have an easier time smoothing it out in no time!

Sanding Chipped Glass to Smooth Surfaces

Now we come to the trickiest task, sanding your chipped glass. But don’t worry! You’ll be able to get your glass looking smooth and chip-free in no time.

First, get a 80-grit sandpaper and wet it with water.

Ensure you use a soft cloth or sponge when wetting the paper—any harder material can scratch the glass surface. You’ll also need a flat-tipped object like a spoon or wooden dowel for rubbing against the sandpaper.

Sand with Short Strokes

Start sanding using short strokes and press lightly on the sandpaper while going over the chip’s edges.

As you go over it more times, switch to longer strokes until you reach an even surface texture.

Reshape Edges

Finally, use the flat-tipped object to reshape any uneven edges around the chips. Do not press too hard as it might cause further damage.

After this is done, take a white cloth and wipe away any dust particles left behind from sanding. Now your chipped glass should be looking smooth and ready for use!

Polishing Chipped Glass With a Dremel Tool

Polishing chipped glass with a Dremel tool is quite simple. Just remember to be careful and work slowly to prevent the situation from worsening!

Here’s what you need to do:

Start by sanding down rough edges with the appropriate grit-sized bit attached to your Dremel tool. Start with a coarser bit, 80 grit, then slowly work up to a finer bit 200-240 grit. This will help smooth out the glass’s chipped portions and remove any sharp edges.

Next, use polishing bits to refine the edges of the glass and give it an overall polished look (e.g., diamond burrs or felt bits). Use light pressure as you move around the edges of the glass in circular motions until it has been completely polished and smoothed out.

You can use special wax or compounds made specifically for polishing glass with a Dremel tool to give it a glossy finish. This is optional but will help protect against further damage and give it an extra shine!

Repairing a Large Chip in Glass With an Epoxy Putty

If you have a large chip or crack in your glass, an epoxy putty is what you need. Epoxy putty is a type of polymer that sets and remains stable after hardening and is suitable for repairing glass and ceramics.

To use epoxy putty for your chipped glass repair:

Clean the area of the chip and any surrounding debris, then lightly sand it to create a better surface for the epoxy to adhere to.

Once you’ve done that, knead together equal amounts of each part of the putty (e.g., A+B) before rolling it into a sausage shape.

Place the putty on the edge of the chip in your glass and press it firmly into place—you may want to wear gloves while doing so—and then smooth it out with a wet sponge or cloth so it’s even with the surface of the glass.

Allow at least 24 hours for everything to set properly before handling the object again or using it as normal.

If desired, lightly sand away any excess epoxy with fine-grit sandpaper before polishing with a non-abrasive cloth or compound to make your glass shine like new!

Tips for Maintaining Smooth, Chipped-Free Glass

Finally, here are a few tips to help you keep your glass smooth and chipped-free:

Keep Your Glass Clean

Cleaning your glass regularly will help prevent dirt or debris from building up and scratching the surface.

Use a mild detergent and warm water mixed with rubbing alcohol to keep it clean and polished. And when using rubbing alcohol, it might be wise to find out how it stains clothes.

Avoid Rough Cleaning Materials

When cleaning, avoid any materials that are too abrasive, like scouring pads or steel wool. These can cause more damage than good!

Avoid Heat Exposure

It’s best to avoid exposing your glass to extreme temperatures, like direct sunlight or heat from ovens or other appliances. This can cause condensation, which can lead to chips and cracks.

Check The Quality Regularly

Be sure to check the quality of your glass regularly. Look for chipped edges or any areas that might need attention promptly so they don’t become bigger problems.

Properly caring for your glass will ensure it remains smooth and chipped-free for years!


Smoothing chipped glass is not complicated, but it does require you to use caution.

It is important to use the right safety equipment and tools and practice patience to ensure the glass is smooth. Following the simple steps discussed here, you can easily smooth out the chipped glass and make it look new again.

Your newly-smoothed glass will be an asset to any room, whether in a window, a table, or a shelf.
