The Way to Protect Historic Natural Stone Structures from the Harmful Effects of Winter: Restora WP 081

Historic natural stone structures form the cornerstones of our cultural heritage. However, these valuable structures face serious threats, especially in cold winter conditions. Freeze-thaw cycles, humidity, and the resulting salt crystallization weaken the internal structure of the stone, leading to cracks, flaking, and ultimately structural deterioration.

The Anatomy of Winter Damage: Why Special Protection is Necessary?

Natural stones have a porous structure. Rainwater and snowmelt seep into these pores. When the temperature drops below zero, the water inside freezes and expands. This expansion creates micro-cracks within the stone.

When the ice melts, the water returns to a liquid state, but these cracks continue to grow in the next freezing cycle. As the process repeats, the damage increases exponentially. In addition, dissolved salts that seep into the rock along with the water crystallize, applying more pressure and causing bulges on the surface.

Restora WP 081: A Balance Between Protection and Breathability

Restora WP 081, in addition to its water-repellent properties, acts as a natural stone surface consolidator. Thanks to its alkali silicate technology, it penetrates deep into the stone and strengthens the pore walls. This increases the mechanical strength of the stone while, more importantly, significantly reducing water absorption.

Why is surface breathability important?

One of the most critical aspects of preserving historical buildings is ensuring they can "breathe." Film layers that completely cover the surface prevent moisture within the stone from evaporating. This leads to moisture buildup inside, deterioration in the underlying stone layers, and even mold growth.

The greatest advantage of Restora WP 081 is that it provides excellent water repellency while maintaining water vapor permeability. This means the stone does not absorb water from the outside, while internal moisture is naturally removed. The prominent technical advantages of Restora WP 081 are as follows:

• Deep Penetration: Thanks to its high penetration properties, it works its way into the internal structure of natural stone.
• Long-lasting protection: Provides a long-lasting droplet effect and reduces maintenance costs.
• Ideal Material Compatibility: Ideal for common historical building materials such as sandstone, limestone, and lightly fired clay products.
• Environmentally and Human Friendly: Thanks to its water-based and VOC-free formula, it is safe for both the user and the environment.

Legacy Carried into the Future

Preserving our historical natural stone structures for the future is only possible by making the right and scientific interventions. Restora WP 081 is a reliable solution that protects against moisture and frost damage caused by cold winter conditions, while respecting the original texture and breathability of the stone.
