With a bit of patience and the right tools, you can restore your sink’s glossy finish and make it look brand new again. This guide walks you through 7 easy reglazing tutorials designed for anyone — even beginners.
Whether it’s a chip, a scratch, or a full-on crack, you’ll find everything you need right here.
Understanding Porcelain Sink Reglazing
What Is Sink Reglazing?
Sink reglazing, sometimes called sink refinishing, is the process of applying a new coating over your old porcelain surface to restore its shine and durability. Rather than replacing your sink (which can cost hundreds), reglazing is a budget-friendly, eco-conscious alternative.
If you’re new to the concept, check out Indy Reglazing’s sink reglazing guide for professional insights.
Why Choose Reglazing Over Replacement?
Replacing a sink often means removing plumbing, countertop sections, and sometimes tile — a nightmare for your wallet and your weekend. Reglazing, on the other hand:
- Saves you up to 75% of replacement costs
- Keeps your sink in place (no major plumbing involved)
- Takes just one to two days
- Results in a glossy, durable finish
If you’re aiming for a professional finish at home, reglazing is your golden ticket.
Tools and Materials You’ll Need
Before diving into the tutorials, gather your materials. Having everything ready makes the job smoother.
Essential Tools for Reglazing
According to Indy Reglazing’s tools and materials guide, here’s your must-have list:
- Fine-grit sandpaper or sanding block
- Epoxy filler (for cracks and chips)
- Paint sprayer or foam roller
- Primer and reglazing coating mix
- Painter’s tape and plastic sheeting
- Clean rags and rubbing alcohol
Safety Gear You Should Never Skip
- Respirator mask
- Safety goggles
- Gloves
- Proper ventilation (a fan or open window)
Safety isn’t optional — reglazing coatings can be strong stuff. Protect your lungs and eyes like a pro.
Preparing Your Sink for Reglazing
Cleaning and Degreasing
First things first — start with a spotless sink. Use a mild cleaner or degreaser to remove soap scum, grime, and residue. Any oil or dirt left behind can cause the reglaze to peel.
Pro Tip: Check out these bathroom hacks for deep-cleaning ideas before you start.
Fixing Cracks and Chips
Cracked porcelain? No problem. Mix your epoxy filler and apply it to the damaged area. Let it cure fully, then sand smooth. This step is critical for a flawless finish.

Masking and Protecting Surrounding Areas
Use painter’s tape and plastic sheeting to protect walls, faucets, and countertops. You don’t want reglaze coating where it doesn’t belong.

7 DIY Reglazing Tutorials to Fix Cracked Porcelain Sinks
Tutorial 1: Assessing Sink Damage
Before grabbing your tools, inspect your sink closely. Identify chips, cracks, and dull areas. Light scratches? Easy fix. Deep cracks? You’ll need epoxy repair first.
Refer to minor repair tips for step-by-step patching advice.
Tutorial 2: Sanding and Surface Prep
Sand the entire sink with fine-grit sandpaper. The goal is to create a smooth, matte surface for the primer to stick to. Don’t rush — surface prep is 80% of the job.
Remove dust using a tack cloth or damp rag.
Tutorial 3: Mixing the Reglazing Coating
Your coating mix is where the magic happens. Follow manufacturer instructions carefully — ratios matter. Poorly mixed coatings can lead to uneven gloss or peeling.
Learn more about coating mix techniques for that pro finish.
Tutorial 4: Applying the Primer Layer
Apply a thin, even layer of primer using your sprayer or roller. Allow it to dry fully before applying the topcoat. This ensures the reglaze adheres firmly.
Pro Tip: Don’t overload your roller — multiple light coats beat one heavy one.
Tutorial 5: Spraying the Reglaze Finish
Now comes the fun part. Apply your reglazing finish in gentle, overlapping strokes. Keep the sprayer about 6–8 inches away for an even coat.
If you prefer rolling, use a foam roller for minimal texture. Learn more about roller options.
Tutorial 6: Curing and Polishing for Shine
Once your coating is applied, let it cure for 24–48 hours. Avoid using the sink during this time.
When dry, buff lightly with a microfiber cloth for that mirror-like reglazing shine (see more tips).
Tutorial 7: Final Touch-Ups and Sealing
Finally, apply a clear sealer for moisture protection. This helps prevent water damage and extends your sink’s life.

Common Mistakes to Avoid in Sink Reglazing
Using the Wrong Coating Mix
Not all coatings are made equal. Using a bathtub reglaze on a porcelain sink might cause discoloration or peeling. Stick with sink-specific formulas.
Explore reglazing formula comparisons before buying.
Ignoring Moisture and Ventilation
Humidity and poor airflow can ruin your finish. Always keep your workspace ventilated — or you might end up with bubbles or uneven drying.
Maintaining Your Reglazed Sink
Cleaning and Sink Care Tips
Use mild soap, water, and a soft sponge for daily cleaning. Skip harsh chemicals or scouring pads — they’ll damage the coating.

Avoiding Harsh Chemicals and Abrasives
Avoid bleach, vinegar, and abrasive cleaners. These can dull your new finish. Instead, check out stain removal hacks for gentle alternatives.
