What is Tyrolean?
If you look up tyrolean in the dictionary you may get a definition such as ‘Tyrolean (Ty-rol-e-an) – a person from Tyrol, (bordering Italy to the south and Austria to the north), who would, on occasion, wear a green felt hat with a feather or brush hat-band ornament.’
The tyrolean we are talking about is a polymer cement and a type of render which is breathable to allow moisture to pass from the inside whilst waterproofing the outside.
How is Tyrolean Made?
Tyrolean is made up of cement and plastic polymers. Polymers are basically plastic particles which are added to the cement. They help bind the concrete and make it less likely to be penetrated by water once it is set.
The polymers are what create the smooth or textured (rough/mottled) finish, which is ideal for exterior wall coating. Tyrolean can be used in manual coating sprayers or powered spray guns to cover exterior walls of buildings.
Characteristics of Tyrolean
Tyrolean comes in powder form and is mixed with clean water before applying.
It is white in colour, but different coloured mixes can be achieved by adding coloured dyes to the water when mixing. This provides a decorative yet protective render to the wall.
Tyrolean is unlike plaster or cement finishes, as is resists cracking, provided it is applied properly. It also helps protect the wall from the weather and provides some insulation.
However, tyrolean is not as popular today compared to other finishes such as roughcast, pebbledash and other cement-based renders and its main use is for repairing or re-touching walls with an existing coating of tyrolean.

Tyrolean Grain Sizes
Tyrolean comes in different grain sizes so that different types of finishes, from smooth (smaller grain size) to quite rough (larger grain size), can be created.
