The act of repairing damaged or worn-out natural stone to a condition that resembles its original appearance is known as natural stone restoration. It can be considered Stone Refinishing which is very natural for stone to deteriorate over time.
What Kinds of Deterioration Can Natural Stone Suffer?
– Oil, rust, and water all leave stains that are difficult to remove. Stains can also be caused by certain meals and cleaning acids; however, this is less prevalent in outdoor environments. Water stains are caused by deposits in the liquid that accumulates over time, but rust stains are caused by metallic items.
Hit Marks, also known as stun marks, are caused by sudden, sharp contact with natural stone, resulting in a white discoloration. Essentially, it causes the rock to fracture by forming weak linkages that rupture through it. Depending on the weight of the blow, hit marks might be superficial or penetrate the entire slab of stone.
Extreme Heat Damage –
Extreme heat can produce thermal shock, which causes the stone to break. When water from melting snow becomes trapped in cracks or joints and then freezes, natural stone can chip or break. This is determined by the porosity of the stone and the amount of water absorbed. Granite, for example, has a porosity of roughly 1%, whereas sandstone has a porosity of more than 20%.
Etching is a process in which an acidic substance dissolves and eats away at the surface of natural stone, leaving a dull impression. It appears as a clear liquid stain in moderate cases; nevertheless, the longer the stone is exposed to chemicals, the worse the damage becomes. Polishing is the best and only true approach to removing these blemishes.
Harm Marks –
When dirt, sand, and other abrasive material get lodged under shoes, they can scratch the natural stone. This normally happens when it comes into contact with materials that are harder than stone. Dragging heavy furniture across stone paving, for example, can leave unattractive scratches and detract from the natural beauty of the stones.
If the pavers are of good quality before being laid, cracks can be prevented with careful installation and design planning. Aside from dramatic weather swings, cracking is typically caused by a weak paving base, inadequate jointing, or even tree roots developing beneath the stone.
A white, chalky substance that can form on the surface of natural stone is known as hazing. This happens when rain and groundwater dissolve salts contained in soil and water. The salt is left behind when the moisture evaporates. It’s a natural occurrence that won’t harm the stone, but it should be removed.
Cleaning large expanses of natural stone regularly is not always practicable. They should, however, be cleaned regularly to remove accumulated contaminants. Easily accessible stone surfaces, such as pathways, steps, and fountains, should be swept and washed with water regularly to keep them free of debris. To eliminate algae or moss, flush the outside pool and patio areas with clean water and a moderate bleach solution. Always get advice from professionals to determine which option is best. Aside from that, routine maintenance should involve checking stone surfaces for structural flaws, movement, degradation, or staining, as well as arranging frequent sealing if necessary.
