Stone carving stone will inevitably undergo weathering during use, whether it is natural stone or artificial stone. So, how should we prevent the weathering of stone? First, let’s understand the factors that cause weathering of stone.
Interaction between organic matter and gas: The surface of some stone carvings often has sporangia of organic matter such as moss and mold attached to them. These organic substances interact with carbon dioxide, sulfur dioxide, and other substances in the air to form various color spots, and form organic acids with water, accelerating the aging and erosion of stone.
Ultraviolet irradiation: Ultraviolet irradiation accelerates the evaporation rate of water in the pores of the stone, which in turn leads to the aging of the stone.
Freeze-thaw effect of water: When the temperature drops below zero degrees Celsius, the freezing of water will cause the stone to expand rapidly after absorbing water, causing the stone to disintegrate and crack.
In response to these weathering factors, we can take the following protective measures:
Regular cleaning and maintenance: Regularly remove organic matter and stains on the surface of the stone, use professional stone cleaners for cleaning, and deal with problems in a timely manner.
Surface protection treatment: The use of stone repellent for surface treatment increases the weathering resistance of the stone and prevents organic erosion and moisture penetration.
Shading measures: Block direct UV rays, such as building an awning or using a sun shield, to reduce the impact of UV rays on the stone.
Freeze-thaw protection: Take measures to prevent water from entering the pores of the stone, such as using materials with good water permeability for paving, to avoid water retention and freeze-thaw effects.
By taking these protection methods, the weathering rate of stone carving stone can be delayed, its appearance and quality can be protected, and the service life can be prolonged. Regular maintenance and upkeep are essential to maintain the beauty and quality of stone carvings.
