Since decades Plaster has been around and the need for smooth monolithic walls is still the favored style. We learn that the Egyptians burned gypsum 5,000 years ago and then ground it into a paste, and combined it with water to be used as a linking material to create the pyramids with the large bricks.Learn more about this at R.Kenward Plastering Contractors

Throughout the US, gypsum plaster was typically spread throughout three coats. The first coat was named the “scratch coat” that was spread on a wooden lath or metal lath and placed on in one move at a thickness of 1/4-1/2,” “then scratched with a scarfier or other sort of rake to make the next coat “key in.” The next day or within a few days, the second coat called “gray paint” was added and long, smooth edges called “darbies” were used to flatten the surface. This coat was finished smoother but left a bit rough to allow bonding to the final coat. This second pass was added at a thickness close to that of the first paint. The “finish coat” was the third and final coat This last plaster coat was a much thinner application, and was usually troweled hard to a smooth finish. The finish coat was usually painted but the product was colored integrally or left the natural color of the raw materials before paint was available. This style is what most people might term “Venetian Plaster,” “Faux Plaster” or “Polished Plaster”

Most people today call any smooth finished wall “Venetian Plaster” with color variation. Venetian plaster is something like a design or method with several thin coats coated one over the other to create a depth-like look. Today the majority of plaster is applied directly over prepared drywall and is made in much thinner coats. The thickness of the plaster structure may rely on drywall substrate preparation. Very thin plaster systems will require the drywall to be finished to level 4 or 5, or a thicker plaster base coat will be required to cover and smooth the imperfections in the drywall. Thicker plaster systems may not require taping of board joints and corners inside or outside, but some sort of treatment will be required before applying a finish coat.

There are many different plaster materials to choose from today which include gypsum, cement , lime, acrylic and even clay. Acrylic plasters that can be bought at most any box store, online or in a specialty supply house are the most popular recently. Finding the right product for the particular application is important. Acrylic plaster is simple to add, can be patched, is extremely robust and the built price is typically less costly. The most popular reason to hand trowel plaster is that it is integrally colored and the color is varied to give depth in the wall or ceiling, so color options should be a high priority when choosing an interior plaster. Similar to clay plaster, gypsum plaster, lime plaster or asphalt plaster, internal acrylic plaster may usually be tinted to any color possible at a relatively small rate. The explanation for this is that the substance is much lighter and the dyes are easily accessible and affordable. Because most acrylic plaster is made at home, and the performance is superior to most other plasters, a plaster system is an economical option.
