glass door and rendered house

Whether you're remodeling your home's exterior or building a new one, rendering your walls is a great way to help your house's quality last and look well-designed.  This is because the process of home rendering adds an extra layer of protection to your wall, besides making it look presentable, it protects the exterior from the elements, pollution, and the natural wear and tear of age.

There are various methods contractors do to render homes. One of the most popular being the Tyrolean render.

Tyrolean render is a method that involves the application of monocouche or sand and cement render. It results in a beautiful, rough, textured finish. The finish looks like a roughcast render and is the usual choice by homeowners unless they prefer a smooth finish.

Although the finish it gives is well-loved by many, there is one disadvantage to this type of finish - cracks.

Because Tyrolean renders require a thick layer of application, temperature changes affect the 16mm render since it isn’t as flexible and cannot withstand the heating and cooling - causing the layers to crack.

So who should use these types of renders? What tools do you need?

Let’s get down and dirty by digging right into the basics of Tyrolean render and what makes it a great finishing effect for your exterior walls.

What is rendering?

Before getting started, we must first understand what rendering is and why this is an important step for the construction or remodel of your home.  If plastering is for interior walls, rendering, on the other hand, is the process of covering exterior walls or interior accent walls.

A render is typically composed of cement, fine sand, and lime. A rendering mortar is applied on the wall layer after layer. The last coat is called the “finish.” There are many finishing effects when it comes to rendering. Stucco, Travertine, and K Rend Tyrolean are excellent examples of render finishes.

Today, we will be taking a deep dive into Tyrolean renders and whether or not you should use it for your home.

What is Tyrolean?

Tyrolean refers to the type of render and type of polymer cement.

It is commercially available in white powder form. It can be applied manually through coating sprays or using an open-hopper spraying machine, a compressor-powered render gun, or a Tyrolean flicker gun. Because of its polymer content, which are generally tiny plastic materials added to cement mixture as some form of a binder to concrete, Tyrolean is efficient in preventing cracks and weather-proofing exterior walls.

What is a Tyrolean render or Tyrolean finish?

Otherwise known as an Alpine finish, a Tyrolean render is a stylish render finish that came from the great Alpine regions of Austria. This type of render finish is used on brick, masonry, and concrete wall surfaces with sufficient suction capabilities.

In the UK, Tyrolean render is the most commonly used finishing effect for commercial buildings and residential properties.

It gives exterior walls a characteristically rough, pebbled, and weathered appearance. A superior alternative to plaster and cement finishes, Tyrolean render, when appropriately applied, can protect walls from fractures, withstand extreme weather conditions, such as rain or snow, for a long time, and offer some form of insulation.

While it comes in white powder form, a Tyrolean finish can be created in many different colours of your choice by mixing it with water and colouring dyes and compounds. Cullamix Tyrolean, for instance, is available in a range of colours.

There are also several choices regarding texture and patterns, which can be achieved depending on how the Tyrolean is manipulated.

The curing and drying process is the most crucial step in Tyrolean rendering. The wall should be prepared beforehand, and the Tyrolean should be applied in thin layers manually or using a Tyrolean flicker gun. Faithfull Tyrolean Flicker Gun is an excellent rendering tool for applying Tyrolean on both interior and exterior walls.

How do you apply a Tyrolean finish?

Here is a quick rundown of the tools you need to do this type of render:

  • Tyrolean flicker gun
  • Tension bar
  • Bucket and trowel
  • Scratch comb

To start applying, you must first thoroughly clean the wall and fill in cracks in the wall. If the wall is new, a few layers of undercoat and intermediate coats are needed to work as an adhesive.

Then a base coat is applied, which you mix with clean water. The mixture should appear thick, creamy, and slightly sticky. Apply the first coat and use a scratch comb to lightly scratch the base coat and leave it to dry for at least 24 hours.

Then apply a few finishing coats using the flicker gun significant

Does Tyrolean render need painting?

You can certainly paint over a Tyrolean render, but be careful. Many recommend washing the walls with a hose before spray painting it. Be sure to lessen the pressure when washing the finish, as you can get moisture into the wall, making it susceptible to damage.

Some have had success with a roller using a shaggy type of roller. There are different types of paint rollers that are designed for Tyrolean renders.

Is Tyrolean render waterproof?

Since Tyrolean renders are a cement based render that has silicone, it has some waterproof properties.Experts still recommend users to be cautious of getting moisture inside the layer to avoid getting cracks and other unwanted damages.
