The difference between Filling Mastic and Sealing Mastic

Filling Mastic and Sealing Mastic are two popular types of mastics used in the construction industry. While they sound similar, they have different functions and applications. In this article, we will discuss the difference between filling mastic and sealing mastic and identify their unique benefits.

Filling Mastic refers to a type of paste that is used to fill gaps or cracks in surfaces such as wood, concrete, or metal. Also known as gap filler, it is commonly used in construction work to improve the appearance and structural integrity of surfaces.

One of the main benefits of filling mastic is its ability to provide a smooth finish to surfaces. Once applied, it can be sanded, painted or stained to match the surrounding area. This makes it an ideal choice for projects that require a seamless finish such as cabinetry, furniture, and window frames.

Sealing mastic, on the other hand, is designed to prevent moisture, air and dust from entering a space. It is often used to seal areas with high exposure to water and other environmental factors, such as bathroom tiles, roofs, and foundations.

Water-proof sealing mastic is highly effective in protecting surfaces from water damage. It forms a water-proof barrier that prevents moisture from seeping through the surface and causing structural damage.

Another type of sealing mastic is heat shrinkable cable accessories. This type of mastic is specifically designed for electrical applications. It is used to seal and protect cable parts exposed to various environmental factors such as heat, moisture, and vibration.

Mastic sealant is a commonly used type of sealing mastic. It is applied to gaps and holes in a variety of surfaces such as windows, doors, and roofing materials. This type of sealant is highly durable and remains intact in harsh environmental conditions such as high temperatures and heavy rainfall.

In conclusion, while both filling mastic and sealing mastic are commonly used in the construction industry, they have different functions and applications. Filling mastic is used to fill gaps and cracks in surfaces, while sealing mastic is used to prevent moisture, air, and dust from entering a space. Additionally, there are different types of sealing mastic with unique properties such as waterproof sealing mastic, heat shrinkable cable accessories use sealing mastic, and mastic sealant. By understanding the differences between these mastics, you can choose the best one for your project.
