Why Do Glossy Tiles Lose Their Shine Over Time?


You've recently installed those stunning glossy ceramic tiles in your kitchen, and the initial shine and sparkle were mesmerizing. However, after a few months, you've noticed that the glossy appearance has dulled. Wondering why this happens? Well, those tiles lost their luster, a common issue many homeowners encounter. But fret not – it's often an easy fix. 

In this article, we'll delve into the reasons behind your tiles losing their shine and provide simple solutions to bring back that glossy finish. From effective cleaning methods to proper re-sealing techniques, we've got you covered in restoring the brilliance to your tiles. With a bit of tender loving care, your tiles can regain their polished and pristine look.

The Science Behind Glossy Tile Shine Loss

Chemical Reaction

The Science Behind Glossy Tile Shine Loss

The glossy shine on tiles comes from a durable coating, typically a polyurethane or epoxy resin. Over time, this coating undergoes a chemical reaction with oxygen in the air, known as oxidation. Oxidation causes the coating to gradually break down, resulting in a loss of shine and a dull appearance. Faster oxidation occurs in areas with more oxygen exposure, such as near windows or in bathrooms with exhaust fans.

Wear and Tear

Foot traffic and daily use significantly contribute to shine loss. As the tile coating erodes from constant contact, scratches form, and the surface becomes uneven. Dirt, grime, and spills accumulate in these tiny crevices, further dulling the appearance. High-traffic commercial settings experience a more pronounced effect, and while regular cleaning helps, the continual friction takes its toll over time.

Moisture Damage

Excess moisture is another culprit of glossy tile shine loss. In bathrooms and kitchens, standing water from splashes, spills, and leaks can seep into microscopic cracks, accelerating the breakdown of the coating. Moisture also encourages the growth of mold and mildew, which feeds on the coating and stains the tile surface. Promptly wiping up leaks or spills and improving ventilation can help prevent moisture-related damage.

In summary, the fade in glossy tile shine occurs due to chemical reactions with oxygen, physical wear from foot traffic and use, and damage from excess moisture. While shine loss is inevitable, steps such as proper sealing and re-sealing, minimizing scratches and stains, improving ventilation, and regular cleaning can slow down the process, keeping your glossy tiles looking nearly as good as new for many years.

Common Causes of Dulling and Fading Tile Gloss

Tiles lose their shine and glossy appearance over time due to exposure and wear. Several factors contribute to dulling tile.

Exposure to Light

Common Causes of Dulling and Fading Tile Gloss

Tiles fade and dull when exposed to ultraviolet (UV) light, whether from the sun or indoor lighting. UV light causes the pigments and dyes in the tile glaze or finish to break down, resulting in fading and loss of gloss. Tiles installed in areas with lots of natural light, like bathrooms near windows, are more prone to fading. Using curtains to block light when the room is not in use can help slow fading.

Foot Traffic and Scratches

 The more a tile floor is walked on, the more the finish will dull. Shoes scuff and scratch the surface, wearing away the glossy top layer. Entryways and hallways typically show the most wear. Placing protective pads under furniture helps avoid scratches, and regular sweeping and damp mopping prevent dirt buildup that can dull the surface.

Improper or Infrequent Sealing

Many tile floors require a protective sealant to lock in the gloss and protect from stains. If a sealer was not applied after installation or is not reapplied regularly, the tile will become dull more quickly. Checking with your tile manufacturer for recommendations on proper sealants and reapplication schedules is crucial. Re-sealing a tile floor can often restore dulled and faded tiles.

Harsh Cleaning Products

Aggressive cleaners, abrasive sponges, and strong chemicals break down the glaze or finish of tiles, causing them to dull over time. Using pH-neutral cleaners and soft sponges or mops when cleaning tile floors is advisable. Rinsing the floor with water after cleaning removes any remaining residue. It's best to avoid products containing ammonia, bleach, or acid, which can etch and damage the tile surface.

Keeping your tile floors sealed and properly protected, limiting harsh cleaning products, and reducing exposure to damaging UV light are the keys to maintaining a high-gloss shine. By taking steps to minimize dulling in the first place, you can keep your tiles looking their best for years to come.

How to Restore and Maintain Your Tile's Shine

Over time, the natural oils and sealants on glossy tile floors and walls break down, causing the surface to lose its lustrous sheen. Rather than accepting dull, lackluster tiles, there are a few steps you can take to restore the shine and keep your tiles glistening like new.

Deep Cleaning

 Deep Cleaning

Give your tiles a deep cleaning to remove built-up grime and residue. Mix a commercial tile cleaner or a natural solution of vinegar, water, and dish soap. Mop the tiles or scrub problem areas with an abrasive sponge or scrubber. Rinse well with water to remove all cleaning solution. Allow tiles to dry completely before proceeding to the next step.


Apply two coats of tile sealer or stone sealer, waiting 2-3 hours between coats. Sealers penetrate the pores of the tile to protect against stains and moisture while also enhancing the natural shine. For high-traffic or heavily used areas like kitchen floors or showers, a sealer specifically for porcelain or ceramic tile is best. Follow the directions to determine how often to reapply for maximum protection.


As an alternative or in addition to resealing, buffing tiles with an electric buffing pad can help restore the surface to a high polish. Rent an electric tile buffing machine and buffing pads of different grits, starting with a coarser pad and progressing to increasingly finer pads. Wipe away dust with a damp cloth and buff until you achieve your desired shine. Multiple passes with progressively finer pads typically yield the best results.

With some periodic tender loving care deep cleaning, resealing, and buffing—you can maintain those gorgeous glossy tiles for years to come. An ounce of prevention is worth a pound of cure, so establish a regular cleaning and maintenance routine right from the start to avoid a loss of shine in the first place. Your tiles will thank you, and so will your eyes and all those who admire your home.


So there you have it. Those shiny new tiles you just installed will inevitably lose some of their luster over time. But with proper care and maintenance, you can keep them looking great for years. Be sure to seal and reseal grout lines, use walk-off mats, sweep and mop gently, and avoid harsh cleaners. And if your tiles do start to dull, restore the shine with a good buffing or re-polishing. It takes a little work, but maintaining that beautiful glossy tile shine is absolutely worth the effort.
