Surface FinishesIntroduction for StonemasonsStonemasonry Department 2012
Plane Face and BroachedPlane faced stone is stone which hasbeen left with a fine chiselledfinished and then polished untilthere are no longer any visible chiselmarks. This finished is often foundon ashlar stonework.Broaching is carried out using a finetipped mel-point to work along lines(normally 8-12mm apart) and leavea “furrowed” effect. This iscommonly found on ashlarstonework.
Dabbed and SparrowpeckedDabbing is carried out using a mel-point to leave a number of identical“dabs” all pointing in one directionand evenly spaced. This surfacefinish is often found on ashlar andsnecked rubble.Sparrowpecking is very similar todabbing with the difference beingthat the “dabs” are much closertogether, do not face in a singledirection and the whole face ofstone has been removed. This isnormally done using a mel-point ora teeth tool.
Tooled and ChevronedTooling (droving) is produced bystriking a 2 inch chisel against thesurface of the stone to leave anindentation. This surface finish isoften left at a 45 degree angle oraround the margins of a bull-facedstoneThe chevron surface finish isproduced using either a mel-pointor ¼ inch chisel to leave a series ofparallel and roughly equidistantarrows. This finish is commonlyfound in Yorkshire.
Bull-face and Split-faceBull faced stonework has been cutto a rough depth and then pitchedto working lines to produce a finishwhich gives the impression of beinga split stone. This finish iscommonly used in various styles ofrubble walling.Split faced stonework is similar inappearance to bull faced but tendsto have a planer surface. It iscommon in snecked and coursedrubble walling and particularlycommon for pre-cast (artificial)stone
Reticulated and VermiculatedThe reticulated surface finish isproduced by sinking five sidedshapes, seperated by ribs, below thesurface of the stonework. It is avery time consuming surface finishand is normally only used sparselyon prestigious buildings.Vermiculated surface finishesresemble reticulated but instead offive sided shapes sunken below thesurface, the shapes are randomlysized and often curved. This surfacefinish is also very time consuming.
Hammer DressedHammer dressing resembles acombination of dabbing and bullfaced stonework and is producedusing a hammer and cleura. Thissurface finish is commonly usedthroughout Scotland.
