At Microcare, we work every day with marble in homes, hotels, offices, and restaurants in Dubai. Many people ask us one question: “Does polished marble need to be sealed?” The simple answer is yes. Even polished marble must be sealed to stay safe, strong, and beautiful.
Marble is a natural stone. It looks shiny and smooth when polished, but inside it is still porous. This means it can still absorb water, oil, and stains. Without sealing, polished marble can lose its shine and get damaged over time.
In this guide, we explain why sealing is important, how often to seal, what sealers to use, and how to care for your marble after sealing.
Why Polished Marble Still Needs Sealing
Polished Marble Has Tiny Pores
Polishing makes marble look shiny and smooth. But tiny pores remain inside the stone. Liquids like water, wine, or oil can enter through these small pores.
Acid Can Still Damage Marble
Polishing cannot stop acid marks. Lemon juice, coffee, wine, and vinegar can still etch marble and make dull spots. A sealer adds an extra barrier to protect against these damages.
Daily Use Wears the Surface
In kitchens, bathrooms, or floors, people use marble every day. Over time, this daily use reduces the shine. Sealing helps the marble stay polished longer between professional services.
How Polishing Affects Marble Porosity
Polishing Reduces Pores But Not All
The polishing process closes many pores. But some small pores always remain. This means marble can still absorb spills.
Different Marbles, Different Porosity
Not all marble types are the same. For example, Carrara marble stays more porous even when polished, while denser marble absorbs less.
Absorption Happens Slowly
Polished marble absorbs slower than rough marble. But if a spill stays too long, it will still go inside and leave stains.
What Happens Without Sealing
Water Rings and White Marks
In bathrooms and kitchens, water can leave white rings. If the marble is not sealed, these marks may become permanent.
Oil and Food Stains
Cooking oils, cosmetics, and food spills can sink deep into unsealed marble. Once inside, stains are almost impossible to remove.
Acid Etching
Acidic drinks and cleaners leave dull spots immediately. Sealing gives protection, but without it, the marble gets damaged fast.
Types of Sealers for Polished Marble
Penetrating Sealers
These sealers go inside the marble pores. They protect without changing how the marble looks. They are best for polished marble.
Topical Sealers
These sit on top of the marble. They create a coating, but sometimes they make marble look cloudy.
Impregnating Sealers
These are high-quality sealers. They protect deeply while keeping the natural beauty of marble. At Microcare, we use professional impregnating sealers for the best results.
How Often to Seal Polished Marble
Kitchen Counters
Seal every 12 months. Kitchens have heavy use, with oils, sauces, and acids touching the surface daily.
Bathroom Vanities
Seal every 12 to 18 months. Water, soaps, and cosmetics slowly wear away sealer protection.
Marble Floors
In low-traffic areas, seal every 18 to 24 months. In busy areas like entrances, seal once a year for best results.
How to Test If Marble Needs Sealing
Water Drop Test
Put a few drops of water on the marble. If the water disappears in 10 to 15 minutes, sealing is needed.
Lemon Juice Test
Drop lemon juice on the surface. If it leaves a dull spot, the sealer is gone.
Stain Test
If stains do not clean with mild soap, it means the marble is unprotected and needs sealing again.
Professional vs DIY Sealing
Professional Sealing
At Microcare, we clean marble completely before sealing. This helps the sealer go deep and work better. We use strong commercial-grade sealers that last 2 to 3 times longer than normal products. Our team knows the right technique for even coverage and long-lasting results.
DIY Sealing
DIY products are cheaper, but results are often weak. Mistakes can make marble look cloudy or streaky. Many people call us after DIY attempts go wrong.
Cost of Sealing Polished Marble
Professional Cost
Professional sealing usually costs between $3 to $8 per square foot, depending on marble type and area size. Bigger areas often get better prices.
DIY Cost
DIY sealers cost $30 to $80 per bottle. But wrong application can waste money and damage the marble’s beauty.
Long-Term Value
Sealing prevents expensive repairs. Spending now saves much more in the future.
Signs Your Sealer Is Failing
Water Absorbs Instead of Beading
If water sinks into marble instead of rolling off, the sealer has worn away.
More Stains Appear
If stains appear often and are hard to clean, protection is gone.
Acid Marks Show Up
New dull spots from coffee, juice, or citrus mean the marble is no longer sealed.
Application Process
Step 1: Cleaning
The marble must be fully clean with no soap, dirt, or old sealer left.
Step 2: Right Conditions
Sealing works best in normal temperature and humidity, not extreme heat or direct sun.
Step 3: Thin Coats
Multiple thin coats of sealer work better than one thick coat. Each coat must dry before adding the next.
Maintenance After Sealing
Use Neutral Cleaners
Always use pH-neutral cleaners. Avoid vinegar, lemon, or strong chemicals.
Clean Spills Quickly
Even sealed marble can absorb stains if liquid sits too long.
Avoid Harsh Scrubbing
Do not use rough pads or brushes. Gentle cleaning keeps both marble and sealer safe.
Different Areas, Different Needs
Kitchen Islands
These need frequent sealing because of oils, sauces, and daily cooking spills.
Outdoor Marble
Weather, sun, and rain damage sealers faster. Outdoor marble must be resealed more often.
Bathroom and Showers
These need water-resistant sealers. Normal sealers may not protect in constant moisture.
Quality Matters
Cheap vs Quality Sealers
Cheap sealers may last only 6 months. Quality ones protect for 12 to 24 months.
Solvent-Based Sealers
These go deeper into marble but need good ventilation.
Professional Sealers
At Microcare, we use high-quality products that last longer than store-bought options.
Common Mistakes to Avoid
Sealing Dirty Marble
Never seal over dirt or stains. It locks the damage under the sealer.
Wrong Application
Do not apply sealer in hot sun or extreme heat. It causes uneven drying.
Thick Application
Do not apply one thick coat. Thin, even coats give the best protection.
