TOPICAL SEALERS

Topical sealers for natural stone and granite sealing protect the surface of the stone from water and oil based contaminants. These sealers come in a liquid form and are applied directly to the face of the stone with a soft cloth. It does not require a stone specialist to apply the sealer but it may to take it off! The topical sealer must then be reapplied. If you plan to use a topical sealer for sealing granite, make sure the product specifies it is for granite.

What this type of sealer does is, it creates a barrier on the surface of the stone to protect it from foot traffic, soil, dirt, oil, and stains. This barrier does not allow the stone to breathe but instead, "sits on top" of the natural stone and forms a protective film. Wax products were used in the past. Today there are more durable products available for natural stone, marble, and granite sealing.

There are two types of topical sealers:

  • Strippable
  • Permanent

Strippable coatings are usually water based and easily removed from the surface of the stone. Most of them are NOT designed for granite.

Permanent coatings are solvent based sealers and very difficult to remove. These are NOT recommended for granite sealing.

How often you need to reapply the natural stone sealer depends on your usage. The more foot traffic and occurrences of soiling, the more often your topical sealer needs to be reapplied. AND, before reapplying a topical sealer, the old sealer must first be removed.

Advantages

  • Some topical sealers contain additives that produce non slip characteristics. This is great for natural stone flooring.
  • The sealer creates a protective barrier between water and oil contaminants, foot traffic, and the stone.
  • Topical sealers protect the stone from surface scratching and etching caused by acidic materials such as orange juice and coke.
  • If you like the shiny, glossy look, a topical sealer can produce a gloss that can be buffed. This allows for the maintenance of a high gloss surface.

Disadvantages

  • Topical sealers alter the appearance of the stone by adding a gloss sheen. They may also deepen the color of your stone. This usually isn't the desired effect wanted on an honed natural stone surface.
  • Moisture is trapped within the stone. The protective barrier doesn't allow the stone to breathe.
  • Because topical sealers create a film on the surface of the stone, it tends to show scuffs, marks, and paths in heavy traffic areas. These marks are removed during the reapplication process.
  • Requires continual reapplication as it wears in heavy traffic areas.
  • The old topical sealer needs to be removed before applying a new coat of sealer. The process of stripping the old topical sealer can be detrimental to the surface of some stones. This also adds higher costs to maintaining your stone.
