Mineral Surfaces

Mineral Surfaces

Nanotechnology on mineral substrates

Mineral Substrates:

Concrete, natural stone, marble, granite, ceramics, glass, etc.
Structural damage due to moisture
The penetration of moisture into the pores and capillaries of mineral
surfaces can cause weather damage through frost or corrosion of the
steel reinforcement. The penetrating moisture can lead to blooming
and salt leakage. In addition, alkali aggregate reactions as well as
penetrated water can lead to frost damage
Advantages of Interlotus StoneProtect®
Interlotus StoneProtect TW (deep penetration) gives a significant
reduction of water absorption (hydrophobisation) in absorbent, mineral
substrates due to its good penetration property, based on the
nanoscale silanes.

Structural damages due to acid rain, salt seepage, efflorescence, frost
damage and corrosion is prevented, because the water can no longer
penetrate deep into the structure of the building material. Long-term
damage such as the alkali-silicate reaction can no longer take place
without moisture

Interlotus coating systems

1. Interlotus Stone Protect
The IL-silanes and -siloxanes, which are only a few nanometres in size,
form a chemical, covalent bond inside the structural components in the
capillaries

2. Conventional coatings
Conventional paint particles adhere to the surface only by adhesion.

Depth effect with nanotechnology

1. Real penetration depth effect
Due to its small size (1 nm), InterLotus StoneProtect TW can
penetrate deep into the building material. There it chemically
bonds with the building substance and hydrophobises the
structure.

2. Corrosion protection
Chlorides and other aggressive ions can no longer migrate or be
transported by moisture to the steel reinforcement.

3. Comparison with conventional coatings
This coating-particles are a hundred times larger than InterLotus
nanosilanes. Therefore they cannot penetrate into the capillaries &
pores.

InterLotus StoneProtect®

The ETC®-effect can be applied on different mineral surfaces, such as:
Sandstone brick, clinker brickwall, concrete pavement stone etc.
Surfaces treated with InterLotus StoneProtect ETC® (Easy-to-clean) have a water and oil repellent effect and a dirt repellent effect.

Dust and dirt no longer adhere well to the surface and are washed off by
rain. In addition, the formation of moss and fungal growth is greatly
reduced. We recommend applying a deep hydrophobic treatment with
Interlotus StoneProtect® TW beforehand to obtain additional protection
against weather damage.

Deep hydrophobic treatment

Terracotta:
Freezing Damage

Flowerpot:
Moisture in the structure freezes, expands and the consequences are: Cracks and spalling.

The advantages of Interlotus StoneProtect ETC® coating are the resistance of the mineral substrates. Protection against weather damage
Interlotus StoneProtect® on concrete slabs - 
making them slip-resistant and keeping them free
from weather damage & dirt. The transparent-
coloured, coated concrete slabs are clean and
free of damage even after 5 years.

Especially in shady and wet areas, stone
surfaces become dirty and overgrown more
quickly. Interlotus StoneProtect ® protects
against this. The ETC-effect makes these
surfaces easier to clean

Interlotus StoneProtect®

Interlotus StoneProtect® on natural stone, concrete and paving stones keeps the
surfaces free from weather damage, growth and dirt.

Interlotus Stone Protect® on natural stone - free from fouling, weather damage & dirt after 10 years.

Natural stone walls coated with Interlotus Stone Protect® in the shade under trees after 10 years of
 outdoor weathering. The wall is still clean and free from weather damage.

Marble / Granite

Marble and granite are open-pored and sensitive to staining.
The use of Interlotus StoneProtect® prevents the formation of stains.

Terracotta

Weather damage due to moisture

Diffusing moisture freezes, expands and the consequences are:
Cracks and spalling.

Terracotta can also be protected against moisture penetration by
Interlotus StoneProtect® TW + ETC. Damage due to frost is
minimised or prevented, depending on the structural material.
