Weatherproof silicone sealant is one of the most common construction materials. It seals gaps and joints between outdoor building surfaces, preventing the ingress of water, air, and moisture. Due to its flexibility and ability to resist changing environmental factors, it's commonly used to seal windows, doors, roof lights, glazing units, and external wall joints.
One of the biggest concerns customers will have with silicone sealant is its lifespan. Generally, a quality weatherproof silicone sealant will last for between 10 and 25 years depending on circumstances. The premium range of exterior-grade and construction sealants will likely last a considerable amount of time, but a cheaper, less durable seal, or a poorly applied product, could start to deteriorate within a few years. There are various factors that will contribute to how long silicone sealant will last.
Sunlight: The primary cause for any degradation is likely to be sunlight; it may well last for 10-15 years if placed out of sunlight. The biggest benefit of using silicone sealant is that it will hold out much better against UV rays than other sealants, but continuous exposure to intense sunlight will cause a breakdown of the structure.
Temperature changes: It has been stated that repeated cycles of heating and cooling, and expansion and contraction on exterior surfaces, can over time lead to the deterioration of the silicone and the bond between the silicone and the surface.
Moisture and weather conditions: Like most sealants, prolonged exposure to rain and moisture, but especially salty air by the coast, will result in premature breakdown. Very high temperatures and freezing conditions will also shorten its life.
Proper application of weatherproof silicone sealant plays a crucial role in the sealant's durability and overall performance. When the surface the sealant is applied to is dusty or oily, or the existing sealant remains, the silicone sealant might not last for the desired period. Attention should also be paid to the joint shape and the depth and width of the gap to allow sufficient space for movement and flexibility.
It also involves reapplication in areas of high exposure, such as exterior window edges and bathroom exteriors, to prevent unnecessary damage to the building structure. The silicone sealant itself demands minimal maintenance after application; nevertheless, periodic checks to known susceptible locations can reveal weaknesses at an early stage.
Like any other weatherproofing product, the sealant does age and wear over the years. Early signs of damage include shrinking and pulling away from the surface; it may also crack, become brittle, or flake off. In this state, the seal no longer effectively protects the structure from moisture and needs to be replaced.
Regular checks, such as periodic inspections every few years, can detect water leaks before significant damage occurs to the building materials. To protect the building structure from unnecessary damage: visible areas, such as the outer edges of windows and the spaces around bathrooms, should be resealed. While silicone sealant requires little maintenance after application, periodic inspections allow the building owner to identify vulnerable areas.
Alstone Silicone Sealant
Alstone Silicone Sealant is a sealing compound that is appropriate for general-purpose construction applications, and it's ideal for filling the gaps, joints, and cracks within the construction of buildings to prevent them from leaking water, air, or dust.
It is mostly used in house or commercial building construction applications in most of the areas, particularly in the application of glass, aluminium, UPVC Profiles, doors, and windows, as well as the joints between outer walls of a house.
Silicone sealant requires little maintenance, but you should inspect it periodically. Over time, cracks may develop, or the sealant might shrink or pull away from the surface. In such cases, these areas should be resealed to prevent moisture from seeping in.
Conclusion
Alstone Silicone Sealant is an affordable yet dependable sealing solution for interiors and exteriors in building construction. Its high resistance to weather and great elasticity ensure long-term performance in any construction sealing application. Proper application and periodic maintenance of this product ensure resistance against moisture and air infiltration.
