Horsehair plaster is not much different from other types of plasters used for coating the buildings. Horsehair plaster specifically is prepared by mixing a few elements which are lime, aggregate, water and animal hair. These materials are mixed together a little before applying it to the lath.
Why is it called as Horsehair Plaster?
Much obvious from its name, the Horsehair plaster contains Animal hair in it due to which it is known as the Horsehair plaster. Hair from the mane and tail of the horse are used in these plasters. The horsehair in the plaster provides a greater binding force and acts as a bridging agent. It controls the shrinkage of the plaster and holds the nibs of the plaster together.
Horsehair is not only used in the plasters for coating the buildings, but it is also used in other materials. It is used in the upholstery, in the brushes used for different purposes and even the bows of musical instruments.
In the post war era, lath and plaster were the two most common plasters used for the buildings, in both the residential and commercial areas. During those times, using the Animal hair in the plasters was not uncommon. But the thing with the Horsehair was that the long hair of the horse tails was perfect for the plaster mixtures.
Throughout the United States, the Horsehair had a long tradition. You’ll see the Horsehair plaster used in almost every old and historic building. To preserve the walls of buildings, horsehair plaster was the best choice so far. It was applied to both the walls and ceilings of buildings and homes.
Also, the horsehair plaster did not take long time to be cured as the other mixtures do. Although its application was time consuming but surely the most versatile mixture.
Is the Horsehair Plaster Still Being Utilized Today?
The horsehair plaster was most commonly used before the 1920s. When the Plasterboard came into use in the 1930s, lath and plaster unfortunately fell out of favor. Plasterboard was more convenient to use for so many different reasons so people started to prefer it more.
Specifically, in Canada and US, the Horsehair plaster was being used until 1950s. But later in 1950s, the Drywall began to replace the plaster.
