Stone is an excellent material for house facades and exterior finishes. Natural stone facades are durable and resistant to temperature changes. Granite, basalt, slate are indispensable for surfaces that are subject to constant weathering.
Marble and travertine is often used for luxury, exclusive buildings in moderately warm climates. These stones are softer, more brittle and more sensitive than granite. They are particularly sensitive to acids and less tolerant of extreme weathering. Acidic liquids can corrode marble and travertine, causing them to change colour and become mottled.
Atmospheric pollution and acid precipitation leave traces in all stone types. Some stone types are more resistant to atmospheric impacts while the others can very sensitive to them. Natural stone facades need special maintainance in order to keep their perfect appearance.
An excellent alternative to natural stone facades are artificial stone facade finishes. Artificial stone facades are non-porous and do not absorb water. Such facades do not need to be impregnated and are easy to clean and maintain. Facades clad in sintered stone are lighter and thinner than those clad in natural stone.
The hardest and most resistant artificial stone material that tolerates maximum wearing and extreme weather conditions is sintered stone. This material is special - you won't be able to damage a quality sintered stone surface by burning or scratching it with a knife. Some sintered stone brands are paint-resistant, which means that graffiti can be easily wiped from them leaving no trace. Because of this feature, sintered panels are sometimes used to clad school facades.
Facades can also be clad with acrylic stone panels. They are practical, and look very modern and elegant.
