Helpful Guides


Limestone Sealer

LIMESTONE DENSIFIER is a water-based impregnating agent of the highest quality, specifically developed to speed up and simplify the mechanical sanding and polishing process of limestone and lime-based materials, which are more difficult to polish on account of their porous nature and their high capacity to absorb water.

Eco-Friendly Formula

LIMESTONE DENSIFIER is characterized by a 100% water-based, eco-friendly formula and for its lack of volatile organic compounds (V.O.C. Free), therefore, its use is not harmful to the environment or for the health of users, either during or after application.

Benefits of Limestone Densifier

Process Efficiency

LIMESTONE DENSIFIER, when used as part of the sanding and polishing process, offers various benefits:

  • It drastically limits water absorption on the floor and prevents all of the problems linked to excessive moisture in the stone.
  • It also speeds up the drying time required by the surface before it can be subjected to other processing or treatment.
  • It speeds up the mechanical sanding and polishing process, allowing the operator to treat larger surfaces within the same amount of time than would be possible on untreated materials, as it reduces the friction between the surface and the polishing tool.
  • It significantly reduces wear and tear to polishing tools as well as the amount of water needed to complete the job.

Enhanced Surface Properties

  • Material is given pronounced damp proof properties.
  • Surfaces become water-repellent.
  • It reduces the possibility of dirt build up on the material.
  • The performance of any stain-proofing product applied afterwards is significantly increased.
  • It also increases the results achieved by the polishing grain used.

Specific Characteristics

Deep Penetration

The specific characteristics of this LIMESTONE DENSIFIER is that it penetrates the limestone deep down, guaranteeing tough, lasting protection against rising damp, which is responsible for most of the problems generally found with this material: persistent damp marks, formation of rust, flaking and pop-ups, and saline efflorescence, which are responsible for attacking the surface.


LIMESTONE DENSIFIER also does not compromise the original breathability of the surface, since it does not create any type of film or alter the original appearance of the material.

Dirt and Foot Traffic Resistance

LIMESTONE DENSIFIER also increases a material’s resistance to dirt and foot traffic, also making it possible to leave a matt, dirt-resistant finish on limestone surfaces that are generally very complicated to reach with traditional treatments.

Food Contact Safety

LIMESTONE DENSIFIER is a definitive solution, as it can withstand the action of de-waxing products and it is also certified for contact with foods and therefore, is a valid solution for protecting kitchen worktops.


Combined Use

LIMESTONE DENSIFIER can be combined with a surface stain-proofer to achieve maximum performance; it will act as a primer to maximize the effectiveness and durability of the stain-proofing treatment applied successively.

Pre-Installation Treatment

LIMESTONE DENSIFIER is also recommended as a pre-installation treatment for limestone:

  • It is used as a 6-side, pre-treatment to prevent rising damp, leaving a high degree of protection without compromising adherence between the underside of the material and the bonding agent used, even in the event that stone can be installed with simple cement mortar or mechanical securing.
  • It is used as a 5-side, pre-treatment (top+edge) in the event that stone can be installed with top-quality mortar or mechanical fastening.


Approximate coverage per 5 Liters is 750 sq ft.


Does limestone need to be sealed?

For the sanding and polishing process, sealing limestone is highly beneficial. LIMESTONE DENSIFIER is designed to address the specific challenges associated with limestone's porous nature:

  1. Efficiency in Sanding and Polishing: LIMESTONE DENSIFIER reduces friction between the limestone surface and polishing tools, allowing for a faster and more efficient polishing process.
  2. Tool Longevity: By minimizing water absorption, the sealer reduces wear and tear on polishing tools, extending their lifespan and lowering maintenance costs.
  3. Quick Drying Time: The sealer accelerates drying times, enabling quicker progression to subsequent treatments or processing steps.
  4. Moisture Protection: LIMESTONE DENSIFIER provides deep protection against rising damp, preventing issues such as persistent damp marks and rust formation.
  5. Surface Quality: Treated surfaces become water-repellent and resistant to dirt buildup, enhancing the overall appearance and durability of the polished limestone.

Sealing limestone with LIMESTONE DENSIFIER is an important step in achieving a high-quality finish while protecting the stone during the sanding and polishing process.
