Pre installation treatment

Natural stone, especially marble and some types of granite are extremely porous and so they are susceptible to stains and dampness from all sides. This makes sealing of the stone essential especially sealing of the back side.

6 side sealer

In case of very porous sedimentary stone like marble it is advisable to apply a sealer to all sides of the stone slab so that it is protected from stains, dampness and salt leaching from all sides.

Back side protector

Porous stone is susceptible to staining from the mortal at the bottom after it has been fixed. This is called efflorescence.


Due to the porous nature of natural stone soluble salts present in water in the mortar tends to leach from the bottom because of capillary effect and forms a white chalky deposit in the surface.

In the picture below we can see the effects of efflorescence on brick. This is a house that is being constructed next to our office, observe the white salt deposits on brick because of hard water that is used for ‘tarai’ of the new construction.

It is necessary to seal the bottom of stone using an anti efflorescence protector before laying of the stone on the mortar.

During installation

Epoxy grout filler (Mastic)

Grout is the gaps between two stone slabs or tiles. This needs to be filled with a filler so that dirt does not get in and the color of the stone is matched. Epoxy resin of varying consistency and colors are available for post installation filling of the gaps between slabs. Epoxy is a resin that is applied using a hand applicator known as a floater of ‘patti’ after the stone has been installed. It usually dries within 24 hours of application.

Crack filling epoxy

Natural stone slabs tend to have hairline cracks and imperfections that spoil its look so these need to be filled with epoxy. Crack filling epoxy has lower viscosity than regular grout filling epoxy so that it is able to penetrate in hairline cracks.

Post installation

Sealers and impregnators

Stone is porous due to presence of numerous channels and gaps in the structure. Because of this the surface gets stained easily by oils, acidic liquids like fruit juices and even by water in case of some very porous marbles. Stones that are exposed to the element are also susceptible to pitting and corrosion because of acid rain. Because of this it becomes necessary to seal the surface so that the stone is protected and maintains its look.

The best sealers, instead of forming a protective layer on the surface, penetrate into its structure filling up the pores so that stain causing liquids cannot get in. These are called penetrating or impregnation sealers which are better than sealers that form a layer on the stone because this layer can be easily removed because of people walking over the floor.

A good sealer makes the stone water repellent which can be tested by putting some water on the floor, a well sealed floor will not absorb the water. The water should break into small droplets.

Usually sealing is done as a last step during grinding and polishing of the stone as part of a new install or a floor restoration project. After the sealer is applied to the floor it is allowed to dry sometimes as long as for 24 hours and then it might be necessary to buff the floor once to remove any time of residue. However some manufacturers sell sealers that can be applied using a brush or roller on clean polished floors so this can even be done by the homeowner as long as the instructions are followed.

Stone floors especially ones made of sedimentary stones are by nature soft and are susceptible to breakage and cracking. Sometimes it might be necessary to strengthen natural stone floors by using chemicals called densifiers or hardeners. The desifier penetrates the surface of the floor and increases the density and strengthens it. It also improves chemical resistance and also seals the floor against water and chemicals.

  1. your site have nice content thank you so much

  2. Perfectly illustrated methods of floor maintenance. Thanks for posting such helpful article.

  3. It really helped when you said that a sealer applied to the floor of a floor restoration project might need twenty four hours to dry, as well as possibly needing to be buffed. I used to think that an hour was sufficient! You did a great job of explaining all of the aspects of time and materials for a successful stone maintenance project.
