Alpinina

This type of limestone is extracted in the heart of the Natural Park of Serras de Aire e Candeeiros, more specifically in Monsanto, Alcanena. Used for a long time cladding the walls of Portuguese houses, this type of limestone presents many positive characteristics. It can be easily confused with some kind of marble when polished, but it ends up having a very superior resistance considering its durability outdoors. In addition to presenting a notable resistance, the Alpinina limestone also integrates very characteristic colours such as: pinkish cream coloured background with strong white calcite lines and reddish fine grain veins.

Finishings

Polished

Abrasive treatments with repeated applications result a shiny surface, highlights the color and properties of the natural stone.

Leather

Brushing the slab with a range of brushes and the result is a slightly undulating surface, very soft, warm and smooth to the touch.

Sandblasted

Blasting silica sand against the material through an air gun and generates very small craters.

Bushammered

Hitting the material, with a masonry tool called a bush hammer, that generates uniformly distributed craters of different sizes over the surface of natural stone.

Honed

A honed finish is identical to the polished finish, the surface is smooth but without glare or light reflections.

Brushed

Abrasive brushes under high pressure generate a touch-sensitive and smooth surface of natural stone.

Splitted

Splitting stone either by hand or by machine so that the surface exhibits a natural quarry texture.

Scratched

Scratched finish is applied so that the surface exhibits a texture with straight reliefs and natural colours.

Sawn

Rough and irregular surface with small furrows and undulations in a mate tone.
