The lay-on and mix is the same as with regular texturing. however after a uniform and smooth coat is placed on the ceiling and the edges are cut in; a special rectangular sponge with a handle is run across the ceiling in overlapping and circular motions. This takes some skill and practice to do well. The overall look is a fishscale type pattern on the ceiling, closet wall, etc. Even though retarder is typically used; care must be taken to clean out the sponge thoroughly when finished as any plaster that hardens inside it will be impossible to remove. Ceilings Stilts are often required to plaster most ceilings and it is typically harder to lay-on and work than walls. For short ceilings one can also work with milk crates. The difficulty of working upside down often results in plaster bombs splattering on the floors, walls and people below. This is why smooth ceilings, that use no retardant and sometimes even accelerant, are done before the walls. Retarded plaster can easily be scraped off a smooth plaster wall when wet. Any splatters from a smooth ceiling can easily be scraped off bare blueboard but not from an already plastered wall. Care must be taken when standing under your trowel or another plasterer. The general difficulty of working a smooth ceiling fetches a higher cost. The technique is the same as a smooth wall but at an awkward angle for the plasterer. Tools of the trade Examples In England, fine examples of plasterwork interiors of the early modern period can be seen at Chastleton House, (Oxfordshire), Knole House, (Kent), Wilderhope Manor (Shropshire), Speke Hall, (Merseyside), and Haddon Hall, (Derbyshire). Some examples of outstanding extant historical plasterwork interiors are found in Scotland, where the three finest specimens of interior plasterwork are elaborate decorated ceilings from the early 17th century at Muchalls Castle, Glamis Castle and Craigievar Castle, all of which are in the northeast region of that country. The craft of modelled plasterwork, inspired by the style of the early modern period, was revived by the designers of the Arts and Crafts movement in late-19th- and early-20th-century England. Notable practitioners were Ernest Gimson, his pupil Norman Jewson, and George P. Bankart, who published extensively on the subject. Examples are preserved today at Owlpen Manor and Rodmarton Manor, both in the Cotswolds. Modern ornate fibrous plasterwork by the specialist company of Clark & Fenn
