Details about Sealing Mastic and Filling Mastic

Sealing mastic and filling mastic are both types of compounds used in various applications to seal and protect materials against moisture, dust, and other external factors.

Sealing mastic is a type of compound that is used to form a watertight seal around pipes, cables, and other objects. It is typically made from a mix of mineral fillers, polymer resins, and other additives that provide resistance against weather, UV radiation, and physical damage. Sealing mastics are known for their excellent insulation properties which make them suitable for electrical insulation applications.

Filling mastic is a type of compound that is used to fill gaps, voids, or cracks in materials such as wood, concrete, or metal. It is typically made from a blend of polymers and mineral fillers that provide a permanent, durable seal. Filling mastics are known for their excellent adhesion to various materials and good resistance to weather, chemicals, and other environmental factors.

Both sealing and filling mastics are applied in various ways depending on the specific application. Some common application methods include troweling, brushing, spraying, or pouring the mastic. The curing time of most mastics varies based on the type of compound and the thickness of the application layer.

Upon cure, it acts as a barrier against moisture, dust, and other environmental factors, protecting the application from weathering, corrosion, or other types of damage.
