Product Overview: Rust-Oleum Tub and Tile Paint

Rust-Oleum Tub and Tile Paint is a two-part epoxy acrylic coating designed to refinish bathroom surfaces like sinks, tubs, tiles, and showers. It dries to a smooth, porcelain-like finish and is formulated to hold up in high-moisture environments where standard paint would fail.

This specialty paint resists peeling, discoloration, mildew, and everyday wear. It’s a practical choice for DIYers looking to restore a sink’s appearance without the mess or expense of a full renovation.

Available in colors like White, Biscuit, Almond, and Gray, it pairs easily with most bathroom styles. Just be sure to mix both components properly and use the product within its 6-hour pot life to ensure a strong, lasting bond.

TIP: Test the color first on a small, hidden area of your sink if possible.
Lighting and surface texture can affect how the final color appears once dry.

Do’s and Don’ts of Using Rust-Oleum Tub and Tile Paint

Getting a professional-looking finish with Rust-Oleum Tub and Tile Paint is all about preparation and patience. Follow these key tips to ensure your project lasts:

---

✅ Do:

• Thoroughly clean the surface with a strong household cleaner like Comet or Lime Away to remove all soap scum, grease, and grime.
• Remove all caulk before painting and reapply new caulk only after the paint has fully cured.
• Sand the surface with 400-grit sandpaper to help the paint adhere better.
• Mask off nearby areas like countertops, walls, and drains with painter’s tape and paper.
• Use a high-quality synthetic brush or foam roller to apply thin, even coats.
• Mix Parts A and B thoroughly and follow the timing instructions—once mixed, the paint must be used within 6 hours.
• Ensure proper ventilation by opening windows and using a fan. Always wear a respirator rated for paint fumes.
• Allow each coat to dry fully (at least 1 hour) before adding another.
• Let the painted surface cure for a minimum of 3 days before exposing it to water or reapplying caulk.

---

❌ Don’t:

• Don’t skip the prep work. Painting over dirt, soap, or old caulk will cause peeling or uneven coverage.
• Don’t use in extreme temperatures. Application should only happen between 50°F and 90°F (10°C–32°C).
• Don’t rush drying or curing times. Using heat guns or fans too soon can cause bubbling or cracking.
• Don’t paint over chips or cracks without repairing them first, or they will show through the final finish.
• Don’t re-stir the paint after mixing Parts A and B—this can introduce bubbles.
• Don’t use abrasive cleaners or scrub pads on the painted surface once cured—stick to mild soap and water.
• Don’t store leftover mixed paint. Once combined, the paint has a limited pot life and will harden within hours.

Following these do’s and don’ts will help ensure your newly painted sink looks flawless and holds up beautifully over time.

• Curing Time: 3 days
• Total Time: ~3.5 hrs of active work + 72 hrs cure

Step 1: Gather Your Supplies

Make sure you have everything ready before starting, as timing is critical once the paint is mixed.

You’ll need:

• Rust-Oleum Tub and Tile Paint (Parts A & B)
• Respirator or mask (rated for paint fumes)
• Safety goggles and gloves
• Comet or similar abrasive cleaner
• Lime Away or similar hard water/stain remover
• Mild detergent
• Rags or paper towels
• Scrub brush
• Abrasive pad
• 400-grit sanding sponge

• Floor fan for ventilation

Step 2: Prepare the Surface

Proper prep is key to a long-lasting, smooth finish.

1. Remove faucet, drain, and any hardware for easier access.
2. Clean thoroughly using Comet and a scrub brush. Focus on removing all grime and buildup.
3. Apply Lime Away to dissolve hard water stains. Let sit for 5 minutes, then rinse and dry.
4. Remove all caulk between the sink and counter using a plastic caulk remover or razor blade.
5. Sand the entire surface with a 400-grit sanding sponge to roughen it up and help the paint adhere.
6. Rinse and dry completely.
7. Wipe with a tack cloth to remove fine dust particles.
8. Mask surrounding areas (countertop, walls, floor) with painter’s tape and paper or plastic.

Step 3: Mix and Apply the Paint

Work quickly and carefully once you start this step.

1. Ensure good ventilation. Open windows, run a fan, and wear your respirator.
2. Open Part A (Activator) and Part B (Base). Stir each separately, then combine and mix thoroughly.
3. You now have 6 hours to use the mixed paint—do not delay.
4. Using a synthetic brush or foam roller, apply the paint in thin, even strokes, starting from one corner and working around.
5. Avoid overbrushing. Any small bubbles or streaks will settle as the paint dries.
6. Allow the first coat to dry for at least 1 hour before applying the second coat.
7. Apply a second thin coat, using the same method. You can do a third coat if needed for full coverage.
8. Wait 1 hour, then carefully remove the painter’s tape to avoid pulling up dried paint.

---

Step 4: Let It Cure

Patience pays off here.

1. Allow the sink to cure undisturbed for at least 3 full days before exposing it to water or reinstalling hardware.
2. After curing, reapply caulk where needed using white or clear bathroom caulk.
3. Clean with mild soap and a soft cloth going forward—avoid abrasive pads or harsh chemicals to protect the finish.
