What is Fair Face?
Fair face plaster, also known as fair-faced concrete plaster or simply fair face, is a type of plaster that is applied to surfaces with the intent of leaving them exposed and visible, rather than covering them up with paint or other finishes. The term “fair face” comes from the practice of leaving the plastered surface in its natural, unaltered form, showcasing its texture and color. It is commonly used in both interior and exterior applications to create a clean, modern, and minimalist look.
In a construction context, fair face plaster is used to finish the surfaces of walls and ceilings made of concrete or masonry. Unlike traditional plaster, which is often painted or finished with decorative coatings, fair face plaster allows the underlying material to remain visible, offering a raw, industrial aesthetic that is becoming increasingly popular in contemporary design.
Composition of Fair Face
Fair face plaster is typically composed of a mix of cement, sand, and water, similar to regular plaster used in construction. However, what distinguishes fair face plaster is its specific formulation and application process, which is designed to achieve a smooth, aesthetically pleasing surface that requires minimal additional finishing. Below are the key components:
- Cement: The primary binding agent in fair face plaster, cement provides strength and durability. Ordinary Portland cement is often used, but specialized types may be selected for particular performance requirements.
- Sand: Fine aggregates such as sand are mixed with cement to form the plaster. The texture of the sand plays a role in determining the final finish, with finer sands resulting in a smoother surface.
- Water: Water is added to the dry ingredients to activate the cement and create a workable paste. The ratio of water to cement is critical in ensuring proper bonding and the desired consistency for application.
- Additives and Plastering Agents: In some cases, additives such as retarders, accelerators, or polymers may be added to improve the workability, drying time, and adhesion of the plaster. These additives can also contribute to the material’s sustainability and performance.
- Lime: While not always used, lime may be incorporated into the plaster mix to enhance flexibility and reduce cracking. Lime-based plasters are often favored for their environmental benefits, as lime is more sustainable than cement in terms of carbon emissions.
The careful balance of these components is critical in producing fair face plaster with the right combination of smoothness, durability, and visual appeal.
