Tyrolean (Ty-ro-lean) is a polymer cement and a type of render, but is breathable to allow moisture to pass from the inside whilst waterproofing the outside.
It can be used in manual coating sprayers or powered spray guns.
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.
Copied process from internet is pasted below as i have never used it.
Tyrolean flicker gun consists of a reservoir, a hand crank attached to a spindle with comb like wires and a tension bar to adjust the amount of splatter.
Other than the flicker gun, the only tools required for applying a tyrolean finish are a bucket and a trowel or stick for mixing and, if necessary, a ladder or scaffold.
The flicker gun tool uses the wires to scoop the material and flick it in splotches onto the wall surface.
It is possible to hire the tool daily or weekly however, the tool itself is not that expensive to purchase.
Tyrolean finish is applied in thin layers and usually requires 4-6 coats.
Tyrolean mixture should be a slurry consistency thin enough to flick but thick enough not to slide off the wall.
The tyrolean mixture should be mixed in a bucket and kept nearby for refilling the flicker gun tool.
It is extremely important to remix prior to refilling the tool.
It is helpful to refill approximately the same amount into the flicker tool each time in order to keep the application even.
How To Apply The Tyrolean Finish To Plastering / Rendering
Once the wall is prepared, through a thorough cleaning and repairing any cracks, the tyrolean mixture can be applied to the wall.
While keeping the flicker tool square to the wall and approximately 250 mm from the wall, turn the hand crank with a steady motion and work slowly and consistently across the wall surface.
In order to keep the layer a consistent thickness, keep the gun at the same angle, move at a consistent speed and turn the hand crank at a steady rate.
A good pattern for application is to work from the top left to right then down and back to the left.
Although arm fatigue is an issue with the hand crank, it is important to work with a wet edge; if the edge dries, a noticeable line may be present in the finish.
It is a good idea to practice first if this is your first attempt at using the tyrolean flicker tool.
Once the first layer begins to set, apply the next layer. Repeat the process until there are 4-6 thin coats.
Tyrolean Render Mix (Mixture Ratio and Ingredients)
The mix for this type of tyrolean render finish rendering is usually a combination of lime, cement, sand and water and the ratio for the mix is 1 (cement) : 2 (sand) : 1 (lime).
When making up a mix ensure that the water is clean and that you add it gradually to ensure that you create the right consistency and don't overshoot the proportion of water to end up with a runny mixture too early.
