When your bathroom or kitchen tiles are looking dated, chipped, or just plain tired, refinishing them can feel like a smart, cost-effective alternative to full replacement. But while tile refinishing can deliver stunning results and extend the life of your tilework, it’s not as simple as grabbing a brush and slapping on some paint. Many homeowners—and even some contractors—make common tile refinishing mistakes that lead to poor results, wasted time, and money down the drain.
In this post, we’ll walk you through the most frequent tile refinishing errors, explain why they matter, and share how to avoid them. Whether you're considering a DIY tile project or hiring a pro, this guide will help ensure you get the durable, beautiful finish you’re after.
1. Skipping Proper Surface Preparation
One of the most overlooked yet critical steps in tile refinishing is surface preparation. It’s tempting to jump right into the refinishing process, but failing to clean and prep the surface thoroughly is one of the most damaging tile refinishing mistakes.
When tiles are not properly cleaned and deglossed, the refinishing materials can’t bond correctly. This leads to peeling, bubbling, or a patchy, uneven surface that won’t last. Any soap scum, oils, mildew, or even cleaning product residue left on the tile can interfere with adhesion.
How to avoid it:
- Deep-clean tiles using a degreasing cleaner
- Remove all caulk and mildew
- Sand or etch the tile surface to create a bondable texture
- Rinse and dry completely before applying any coating
Skipping this step may save time initially, but it usually results in the need to redo the job—costing you more in the long run.
2. Using the Wrong Products or Materials
Not all paints or coatings are created equal—especially when it comes to areas exposed to water, humidity, and daily wear. Using regular household paint or a non-specialized finish is a surefire way to ruin your project.
Generic coatings won’t stand up to moisture or abrasion. They may look good initially but will quickly chip, discolor, or wear unevenly. For tile refinishing to be successful, especially in bathrooms and kitchens, you need high-performance products made specifically for ceramic or porcelain surfaces.
How to avoid it:
- Use products designed specifically for tile refinishing
- Choose coatings that are heat-, moisture-, and chemical-resistant
- Follow manufacturer instructions for mixing and application
Professionals like Bathtub Made New use industrial-grade refinishing products that deliver a smooth, long-lasting finish designed to handle the demands of everyday use.
3. Poor Ventilation and Safety Oversights
Refinishing tiles involves chemicals that release strong fumes during application and curing. One common mistake is failing to ventilate the area properly, which not only puts your health at risk but can also affect the finish.
Insufficient airflow can prevent coatings from curing properly, leading to tacky or soft finishes that never fully harden. Even worse, some homeowners try to tackle tile refinishing without the proper safety gear, exposing themselves to toxic fumes.
How to avoid it:
- Use fans, open windows, and set up exhaust systems if needed
- Always wear a respirator, gloves, and eye protection
- Keep pets and children away from the area until the coating is fully cured
A safe work environment ensures not only your health but also the quality and longevity of the finished surface.
4. Rushing the Drying or Curing Process
Another major tile refinishing mistake is impatience. Once the coating is applied, many homeowners can’t wait to use their new shower or kitchen backsplash—but doing so too soon can ruin the entire job.
The refinishing material needs time to cure properly. If you expose it to water or cleaning products too early, the finish may peel, bubble, or lose its shine.
How to avoid it:
- Follow product-specific drying and curing times—often 24 to 72 hours
- Avoid water, steam, and contact with the surface during curing
- Allow for extra time in humid or poorly ventilated spaces
If you’re investing time and money into tile refinishing, giving the coating time to cure is crucial to getting the results you want.
5. Uneven Application or Inconsistent Coating
Even the best refinishing products won’t deliver a great result if they’re applied incorrectly. Uneven coverage, drips, or brush marks are telltale signs of poor application.
Inconsistent coating thickness can lead to dull spots, premature wear, or bubbling. Applying too much product at once can cause sagging, while applying too little can leave the tile vulnerable to damage.
How to avoid it:
- Apply in multiple thin, even coats rather than one thick layer
- Use the right tools: foam rollers, spray guns, or specialty brushes
- Maintain a steady hand and overlap strokes to avoid visible lines
Professional tile refinishers are trained to apply coatings with precision, ensuring smooth, even finishes that look brand new.
6. Neglecting to Repair Cracks or Grout Damage
Another common error is attempting to refinish tiles without first repairing damage. Cracked tiles, missing grout, or failing caulk should all be addressed before starting the refinishing process.
If these issues are ignored, the refinishing coating may crack or peel along the damaged areas. Water can also seep through broken grout or tile lines, leading to mold or mildew underneath the finish.
How to avoid it:
- Inspect all tiles and grout lines beforehand
- Replace or repair cracked tiles
- Re-grout or re-caulk as needed, allowing time for it to dry before refinishing
A smooth, intact base is essential for a durable, beautiful refinished surface.
7. Choosing DIY Over Professional Help (When It’s Not the Right Fit)
Tile refinishing can look deceptively simple on YouTube tutorials, but it often requires specialized tools, materials, and techniques. While a skilled DIYer might be able to handle a small backsplash, most tile refinishing projects—especially in bathrooms—are best left to professionals.
DIY jobs often suffer from inconsistent finishes, improper prep, or inferior products. In many cases, homeowners end up calling a professional to fix what went wrong, spending more than if they had hired someone from the start.
How to avoid it:
- Be honest about your experience level
- Consider the size, location, and complexity of the job
- Hire a trusted, experienced refinishing company if you’re unsure
At Bathtub Made New, we help homeowners transform their spaces with high-quality refinishing services that are affordable, durable, and hassle-free.
8. Not Cleaning or Maintaining Properly After Refinishing
Even after a tile refinishing job is complete, maintenance mistakes can undo your hard work. Using harsh cleaners, abrasive sponges, or bleach can damage the coating and cause it to lose its shine or degrade faster.
Proper care is essential to keeping your newly refinished tiles looking great for years.
How to avoid it:
- Use only mild, non-abrasive cleaners
- Avoid bleach, ammonia, and harsh scrubbing pads
- Gently clean surfaces regularly and dry off after use when possible
Refinished tile is durable, but it still needs proper care to maintain its beauty.
