Claire KennedyRepairing rust spots before reglazing isn’t just a good practice—it’s absolutely essential if you want a long-lasting, smooth, and professional-looking finish. Whether you’re working on a bathtub, sink, or shower, rust is one of the biggest enemies of a successful reglazing job.
In this guide, we’ll walk through 7 detailed reglazing tutorials you can follow step-by-step, even if you’re not an expert DIYer. And because rust repair connects closely to proper maintenance, we’ll also include internal links to help you explore related guides like basic maintenance, cleaning products, and long-term care.
Let’s get started.
Understanding Why Rust Repair Matters Before Reglazing
Before diving into the rust-removal tutorials, it’s crucial to understand why this step matters. Reglazing over rust traps corrosion under the coating, guaranteeing future peeling, discoloration, and weakening of the surface.
What Causes Rust on Tubs and Sinks?
Rust usually forms when:
- The coating chips or wears off
- Metal surfaces are exposed to humidity
- Cleaning products strip away protective layers
- Hard water accelerates corrosion

Are Rusted Surfaces Safe to Reglaze Without Repair?
Short answer? No.
Reglazing over untreated rust is like painting over a moldy wall—eventually the problem resurfaces and gets worse. Rust spreads beneath the coating, causing bubbling and peeling.
Tools & Materials You Need for Rust Repair
Before beginning the tutorials, gather your supplies so the process flows smoothly.
Essential Tools
You’ll need:
- Sandpaper (80–400 grit)
- Wire brush
- Oscillating tool or grinder (optional, but helpful)
- Putty knife
- Microfiber cloths
If you’re into bike repair as well, many tools overlap with those used in advanced repairs and maintenance—another reason to invest in quality equipment.
Cleaning Products & Rust Removers
Stock up on:
- Non-abrasive cleaners
- Rust remover gel
- Vinegar or lemon-based dissolvers
- Mineral spirits
Protective Gear
Always use:
- Eye protection
- Gloves
- Mask (especially during sanding and priming)
Tutorial 1: Surface Cleaning & Degreasing
Cleaning is the first and most important step in nearly all reglazing tutorials. A dirty surface hides rust, oils, and debris that prevent proper adhesion during reglazing.
Why Cleaning Comes First
Cleaning eliminates:
- Soap scum
- Body oils
- Mineral residue
- Loose particles around the rust
If you skip this step, the rust you’re about to repair won’t bond properly with the filler or primer.
Best Cleaning Products for Prep Work
Use:
- Non-abrasive cleaners
- Degreasers
- Baking soda paste for mild buildup
To learn more about cleaning and product choices, explore cleaning product guides.
Tutorial 2: Identifying Deep vs. Surface Rust
Not all rust is the same. Some can be sanded away easily; other spots may require deeper repair work.
How to Inspect the Damage
Check for:
- Color: Surface rust is light orange; deep rust is dark brown or black
- Texture: Pitted metal means deeper corrosion
- Flaking: Indicates the metal has deteriorated under the coating
When to Call a Professional
If rust extends beyond the surface or compromises structural integrity, hire a pro. Reglazing a severely rusted bathtub may require advanced techniques similar to those found in advanced techniques.
Tutorial 3: Sanding & Grinding the Rusted Area
Sanding is the heart of rust removal. It prepares the surface for fillers and primer.
How to Remove Surface Rust Properly
- Start with coarse sandpaper (80 grit).
- Sand until all orange or brown coloring disappears.
- Switch to medium grit (150–220).
- Finish with fine grit (320–400) for smoothness.
Keep dust away from the rest of the room with a vacuum or damp towels.
Tools for Smoother Surface Prep
For faster sanding, use:
- Oscillating multi-tool
- Rotary tool
- Sanding discs
These tools also appear in bike repair settings described in tools & accessories.
Tutorial 4: Applying Rust Converter
Once rust is removed, applying a rust converter ensures that any microscopic corrosion doesn’t spread under the reglazing layer.
Why Rust Converter Is Critical
Rust converters:
- Stop oxidation
- Neutralize leftover corrosion
- Create a solid surface for priming
Think of it like sealing a wound before adding bandages.
How to Apply It Step-by-Step
- Clean the sanded area with mineral spirits.
- Apply rust converter using a small brush.
- Wait for it to dry fully (usually 1–2 hours).
- Lightly sand again for perfect adhesion.
Tutorial 5: Filling Pitted Metal and Holes
Rust often creates tiny pits or even small holes. Reglazing tutorials must include filler application or the final coat will look uneven.
Using Epoxy Fillers
Epoxy putty is perfect for:
- Filling small pits
- Smoothing rough patches
- Repairing shallow holes
Mix the epoxy according to the instructions. Press it firmly into the metal and flatten it with a putty knife.
Smoothing the Surface for Reglazing
After the epoxy dries:
- Sand until it’s perfectly flush.
- Wipe the area with a microfiber cloth.
- Repeat filling if needed for a flawless finish.
Tutorial 6: Priming the Surface Before Reglazing
Priming is what gives your reglaze something strong to cling to.
Choosing the Right Primer
Use a high-bonding primer that adheres to:
- Metal
- Porcelain
- Ceramic
Self-etching primers are excellent because they chemically bond to metal.
How Primer Improves Reglazing Results
Primer:
- Prevents future peeling
- Creates a smooth glaze layer
- Helps the topcoat cure evenly
This step is similar in concept to wheel alignment—prep work determines performance.
Tutorial 7: Final Prep & Masking for Reglazing
You’re almost ready to reglaze. But before applying the final glaze coating, you need proper masking and dust control.
Surface Dust Removal
Use:
- A tack cloth
- Microfiber cloth
- Vacuum with a brush attachment
Dust is the enemy of a smooth reglaze.
Masking for a Clean Finish
Mask:
- Faucets
- Drain area
- Tile edges
- Floor area

FAQs
1. Can I reglaze without removing rust first?
No. Reglazing over rust guarantees peeling, bubbling, and failure within months.
2. What’s the fastest way to remove rust before reglazing?
Sanding combined with a rust converter provides the quickest professional-grade results.
3. Do I need power tools for rust repair?
Not always, but tools like an oscillating multi-tool speed up sanding significantly.
4. How long should I wait after applying epoxy filler before sanding?
Most epoxies cure within 1–2 hours, but always check the manufacturer’s instructions.
5. Can I use vinegar instead of a rust remover?
Yes, for light rust. For deeper corrosion, commercial rust remover is more effective.
6. How soon can I use a reglazed tub or sink?
Usually 24–48 hours, depending on the glazing product.
7. What maintenance should I follow to prevent future rust?
Use non-abrasive cleaners, dry surfaces after use, and follow weekly maintenance routines.
