Ashlar detail is a term used to cut out the render to form a groove on the face of the facade.
The is done using a tool which is made up to suit each job
Ashlar effect render has been popular since the 18th century and is still used to replicate lines to either a block effect or to form bands.
At Devon render systems we were recently the chosen contractors to carry out the rendering on a high spec job @ filliegh estate in North Devon.
We firm the raised quoins with timbers and then run in the band lines using tools made up especially for this job.
