Porous plaster is a type of material primarily used in construction and home improvement projects. It is a highly absorbent mixture made from various substances, commonly including gypsum or cement, blended with water and other additives. The resulting mixture is then applied to walls, ceilings, or other surfaces and left to dry, forming a solid and porous plaster coating.
The term "porous" refers to the ability of the plaster to absorb and retain moisture. This quality makes it ideal for use in areas where moisture control is important, such as in bathrooms or basements. The porous nature of the plaster allows it to absorb excess moisture from the air, which helps to regulate humidity levels and prevent the growth of mold and mildew.
Porous plaster is known for its durability and ability to withstand different weather conditions. It is often used as a base layer for painting and wallpapering, as it provides a smooth and solid surface for these applications. Additionally, the porous nature of the plaster allows it to effectively bond with other building materials, ensuring a strong and long-lasting finish.
Overall, porous plaster is a versatile construction material that offers excellent moisture control and durability. Its ability to absorb moisture, regulate humidity, and provide a solid foundation makes it a popular choice for both residential and commercial applications.

The word "porous" comes from the Latin word "porus", meaning "pore" or "passage". It entered English from the Old French word "poreux", also meaning "porous". The term "plaster" has its origins in the Old English word "plæster", which can be traced back to the Latin word "emplastrum", meaning "a plaster, a salve". "Porous plaster" is a compound term combining these two words, referring to a type of medical plaster that has small holes or pores through which certain substances can pass.
