Protect Your Marble from Water, Oil and Stains

Marble can take in water, oil, and food spills. This can leave dark marks or stains. A marble sealer is a liquid made to slow this down. Send us photos before you buy or use one.

Check New Marble Before It Is Installed

  • Before It Is Cut or Installed:Check the marble before it is cut, moved, or installed.
  • While It Is Stored:Look for water marks, dust, oil, or other marks made while the marble was stored or moved.
  • Where Water Can Reach It:Think about bathrooms, kitchens, outdoor areas, and water that may come from under or behind the marble.
  • Which Sides Need Sealing:Seal only the sides that need it. You may not need to seal the whole piece.
  • Check the Glue or Cement:Make sure the sealer does not affect the glue or cement used to fix the marble.
  • Test a Small Spot:Test a spare piece or a hidden spot before sealing the full area.

The right sealer depends on the marble and where you plan to use it.

Check Marble That Is Already Installed

Before using a marble sealer, look for water marks, stains, worn areas, and old polish.

Water Marks and Dark Areas

Look for dark areas, water marks, and spots that take a long time to dry.

Oil and Food Stains

Kitchens, dining areas, and bathroom counters may need more protection from oil, food, and water.

How Quickly the Marble Turns Darker

Some marble turns darker quickly when it gets wet. Other marble takes longer.

Daily Use and Cleaning

Busy areas and strong cleaners can make the sealer wear away faster.

Old Sealer, Wax or Polish

Old sealer, wax, or floor polish may need to be removed first.

The Marble Must Be Fully Dry

The marble must be fully dry before you use a sealer.

Important: Wait until the marble is fully dry. Sealing wet marble can lock in water and cause dark marks.

A Marble Sealer Does Not Repair Water Leaks. It can slow water and oil from entering the marble. It cannot repair a leak or stop every stain. Always test a hidden spot first.

Test a Small Spot Before Sealing Everything

We may ask you to test a hidden spot first. This shows if the colour or shine changes.

The result depends on the marble, the sealer, and how the area is used.

How Do You Know If Marble Needs Sealing?

Place One Small Drop of Water: See how quickly the marble turns darker.
Old Products: Check whether sealer, wax, or floor polish is already on the marble.
Watch What Happens: See how quickly the marble turns darker after water touches it.
Where It Is Used: Check whether the marble is in a kitchen, bathroom, on a floor or wall, or outdoors.
What Touches the Marble: Think about water, oil, food, soap, and cleaners that may touch the marble.
Past Water Problems: Look for wet areas, white marks, dark areas, or places that dry slowly before sealing.

The water test is only a first check. We also need to know where the marble is used and if it had water problems before.

A Good Sealer Should Keep the Marble Looking Natural

A good marble sealer should make stains less likely without changing the natural colour or shine.
