Impregnation for Natural Stone Protection

Blog Home

Impregnants also known as sealers, after application on surfaces of materials like marble, granite, concrete, grout, terrazzo, the absorption of material decreases by 4-10 times. As a result, a time of leaving spillage on surface of the stone increases, which makes it possible to wipe and clean up it without leaving a stains.

How do impregnants work?

1. Qualitative protective impregnation works on the principle of “umbrella”, allows stone surface to breathe, but does not allow water to penetrate inside.

2. The water-repellent effect of the “umbrella” is created by filling pores of stone with protective substance. Chemical protection doesn’t allow water to penetrate inside, but it allows water to evaporate from inside out of stone.

3. Water-repellent impregnation, however, is not effective in case of oil stains that can penetrate through molecules of protective layer.

4. Therefore, it is necessary to use water-repellent and oil-repellent impregnation, which not only protects against penetration of water, but also oil stains.

How to Apply?

Stone impregnation is a simple procedure and does not require special knowledge. The key point in this process is surface cleaning before impregnation and removal of excess impregnant after absorption.

How often should the stone be impregnated?

Impregnants over time change their properties, so it is much easier and cheaper to re-impregnate the stone than pay for its restoration and stains removal. The frequency of impregnation depends on the type of stone and kind of finish.

More porous and frequently used surfaces should be impregnated every 1-3 years. Less porous stones can be impregnated every 3-5 years.
