Ashlar effect using weberpral F, weberpral K
Apply weberpral F or weberpral K to the minimum thickness of the render with regard to the exposure conditions. In most exposure conditions the depth of profile of the ‘ashlar’ will be varied between 5 and 10 mm. Which cut is chosen it is important to maintain at least 15 mm of render at the lowest point. In areas of severe exposure the recommended minimum coverage at any point should be increased to 20 mm. The total finished thickness of render should not exceed 25 mm in any application.

While the render is still green (i.e. set but not yet fully hardened) immediately after scraping finishing mark out ‘ashlar’ cuts using a chalk line. Place tomber battens so the point of the ‘ashlar’ cutting tool TK 11, TK 20 or TAT (see tools page.125 ) will remove the chalk line. Run the ‘ashlar’ cutting tool along the batten until the specified depth of the cut is achieved. Immediately after cutting, brush using a clean soft bristle brush to remove dust.
