A natural stone remains diffusible with impregnation

In everyday use, untreated natural stone is particularly sensitive as a work surface or as a floor covering. However, if the surface is completely closed, the natural rock loses valuable properties. An impregnation is the common and effective compromise. It increases the resistance without completely sealing.

Impregnating or sealing

If natural stone is used in the living area, treatment on pure decorative surfaces such as interior walls can be dispensed with. For outdoor use and effective areas, protection against external influences is indispensable.

A common choice is to choose between impregnation or sealing. Roughly speaking, impregnation is a partial closure to mitigate the delicate properties of the surfaces. The sealing corresponds to a full closure of the surface, which is similar to a painting of natural stone.

Advantages and Disadvantages of Impregnation

One of the most pleasant and beneficial properties of natural rock is its natural "moisture management". The porous surfaces absorb moisture and release it again. The indoor climate is positively influenced. Impregnation preserves this property, but it compromises some of the closing sealing.

Advantages:

  • Dirt adheres less
  • Moisture and moisture penetrate more slowly
  • Moisture and moisture partly run off
  • The pores remain open and can diffuse
  • Maintenance requires less effort
  • Does not produce a smooth surface with a high risk of slippage
  • Can change color shades and colors due to color particle addition Improve texture

Disadvantages

  • There is no complete protection against penetrating moisture
  • Extremely stressed surfaces such as exterior or shower walls are not sufficiently protected
  • Acid sensitivity remains in full
  • No mechanical protection against scratches or dullness
  • Not applicable for crystallized surfaces

Types of stone and Absorbent Properties

While the substance of a sealed natural stone is no longer reached by liquid, impregnation ensures a delay and a partially effective repelling of impinging substances. Outside, the amount of high impinging amounts of water, such as driving rain, decreases. In the interior, especially the longer reaction time is important to be able to remove struck liquids still without staining.

In addition to the type of utility and the load profile, the effectiveness of the impregnation also depends on the type of natural stone. The more absorbent a natural rock is, the more the impregnation efficiency decreases. In general, soft rocks have the higher absorbency:

  • marble
  • limestone
  • travertine
  • sandstone
  • slate

hard rocks are less absorbent:

  • basalt
  • gneiss
  • granite
  • quartzite
  • slate

The impregnating agent must be adjusted to the type of stone and methodically appropriate incorporated. In doing so, specific load patterns can be taken into account. The remedies can be effective against water, provide protection against grease and oil, or deter organic soiling.

A kitchen counter must also be treated with a food safe product. When floor coverings are impregnated, the mechanical abrasion resistance is also to be considered.

Tips & TricksI do not impregnate your natural stone too often. If your stone substance saturates too much, it will unintentionally produce a sealing character. Depending on intensity of use, targeted intervals lie between two and five years.
