Stone Benchtop Sealing

Do I need to seal my benchtop?

A sealer is a solution applied to the surface of natural stone to protect it from staining. Stone benchtop sealing is a necessity on kitchen benchtops, bartops, tables and bathroom vanities as these surfaces are highly susceptible to staining from coloured foods, cooking oils, drinks, make-up, dyes and soaps.

Note that sealing does not prevent etching.

Marble, limestone, travertine and onyx are popular stone choices often used for benchtops, bartops and vanities. These natural, porous stones can become permanently damaged over time if not sealed.

Granite benchtops are not as porous as the softer stones however they can still stain with constant exposure to oils and soaps and will also benefit from sealing.

Engineered stone benchtops, bartops and vanities such as Caesarstone, Essastone, Quantum Quartz, Silestone and HanStone do not usually require sealing according to their manufacturer’s warranty, as the stones come with a factory seal. If staining does occur contact the stone manufacturer to discuss a solution.

The Marble Man can assist with the removal of the stains then assess whether sealing will help to prevent future stains after they are removed.

To ensure even coverage and the best, most appropriate products are used to seal your stone benchtops, bartops and vanities, application is best carried out by a professional.

Penetrating Benchtop Sealers

Are there different types of sealer?

Penetrating sealers are the most effective type of product used for stone benchtop sealing.  They offer protection against staining on marble, limestone, travertine, onyx and granite benchtops, bartops, table and vanities. The sealer soaks deep into the stone and fills gaps in the pores of the stone.  The molecules in the sealer bond with minerals in the stone to form an effective barrier.

High quality penetrating benchtop sealers used by The Marble Man will not peel, flake or turn yellow as some surface coatings do.

Natural Look Sealer
Stone benchtop sealing with a natural look penetrating sealer is an effective method for protecting your stone.  It will not change the colour or surface finish of the stone 

Enhancing Sealer
Stone benchtop sealing with an enhancing penetrating sealer will provide long term protection and deepen the colour of the stone, highlighting its magnificent features.

Penetrating sealers can be water based or solvent based.  Both offer the same protection however solvent based sealers work more effectively on high gloss polished benchtops, as this type of finish does not easily absorb water based liquids.  A high gloss benchtop finish will always be somewhat more protective than a matt honed finish.

A water based sealer is more suited to porous stones such are marble, travertine, onyx and limestone with a low sheen honed finish as it is absorbed easily.

Stone Benchtop Sealing Process

Marble Benchtop After Sealing

How is the benchtop sealed?

Prior to stone benchtop sealing, an assessment will be made by The Marble Man to determine if tough stains need to be removed with a poultice or if polishing or honing is required.  The Marble Man will also assess whether a water based or solvent based sealer will be used depending on the type of stone, location, finish and use.  If the Benchtop has a high gloss finish a solvent based sealer may be used. If the finish is matt or satin it may be more porous therefore a water based sealer may be used. It is a personal choice whether a natural look or enhancing sealer is used.

Step 1
If a poultice, polishing or honing is required this must take place the day prior to stone benchtop sealing to ensure the stone is dry before sealing

Step 2
Cleaning with a special detergent, solvents and an anti-bacterial treatment to remove grease, oil, dirt and contaminants will also take place the day before so the surface is completely dry

Step 3
Once the stone benchtop has been prepared, two thick coats of penetrating sealer will be applied, leaving 10 minutes in between.  The second coat will be applied before the first coat dries completely, then once the sealer has penetrated the stone the residue will be buffed off with a towel.  The stone benchtop can be used immediately after sealing, however avoid getting wet for 6 hours for a water based sealer or 12 hours for a solvent based sealer

What is TuffSkin protection?

Stone benchtop sealing with a surface film is an alternative to using a liquid penetrating sealer.  TuffSkin is a laminate film designed to protect the surface of marble, travertine and onyx benchtops, bartops, tables and vanities from staining and etching.  

  • TuffSkin is made from ‘hard coat’ technology and will resist the daily wear and tear associated with high use surfaces
  • TuffSkin will prevent etching on stone kitchen benchtops, cocktail tables and bartops exposed to: wine, lemon juice, coffee and tea rings, oils and food
  • TuffSkin is ideal for bathroom vanities and will prevent etching from: make-up, toothpaste, mouthwash, toiletries and perfume
  • TuffSkin is available in a gloss or satin finish, which allows a matt, honed stone surface to be transformed to gloss without being polished or a gloss finish changed to a satin.
  • TuffSkin can be removed if it is no longer required or needs replacing, without damaging the stone
  • TuffSkin is easily cleaned with REJUVENATA and a soft cloth
  • TuffSkin has no VOC’s (Volatile Organic Compounds) so there is no smell
