How to Select Silicone Sealant for Outdoor Use?

Consider the Resistive Nature of the Sealant to Climate

When selecting a silicone sealant for outdoor applications, the first consideration should be its formulation for extreme weather conditions. Outdoor areas are always subjected to extreme conditions which include unrelenting sun, torrential rains, sub-zero temperatures, and constant UV radiation. Outdoor silicone sealant should be able to withstand all these conditions as poorly formulated sealants will be damaged and result in cracking, leaking and costly repairs. All sealants should be labeled weatherproof, UV resistant and temperature tolerant, for example, JUHUAN products are excellent as they withstand extreme temperatures and will maintain their flexibility and sealing during extreme heat and cold. Such climate resistance sealants will last long so you will not have to worry about constant sealant replacement.  

Evaluate the Outdoor Materials Used

Outdoor applications use different types of materials including glass, stones, metals, and wood. Not all sealants will work with all these materials. Incompatible sealants will lead to poor adhesion, and possibly damage the materials. As an example, acidic sealants will corrode metals like aluminum and stain porous stones like marble. Nevertheless, neutral silicone sealants are softer and will work with most materials encountered outdoors. If you are sealing granite or marble, you need specially formulated JUHUAN sealants, which bond securely to stone and are safe for it.

Pay Attention to Key Performance Metrics.  

Besides the climate and compatibility, there are three main characteristics that are most important for outdoor silicone sealants. The first one is water resistance: outdoor sealants must block rain, dew and melting snow to prevent water from getting into gaps and causing mold or structural damage. The second one is aging resistance: outdoor sealants must avoid aging, yellowing, or becoming brittle, especially after a long exposure to the sun. The third one is bonding strength, which is the adhesion that keeps the sealant in place, even when the materials expand or contract. Many of JUHUAN sealants have high tensile strength and long-term aging resistance, which makes them great for outdoor use.  

Select the Right Sealant for Different Outdoor Uses.  

Each outdoor project will require a different sealant for it to function properly. For window and door installations, use flexible sealants: these will accommodate slight frame temperature changes to avoid gaps and will prevent the frames from moving. For glass curtain walls, use structural silicone sealants that have strong load-bearing capacities to hold the glass in place. For garden statues or patio tiles, use stone compatible water-resistant sealants. JUHUAN provides a variety of silicone sealants for these specified uses, which makes it easier for you to find the right one for your project.

Conclusion: How to Choose Sealant Wisely

It isn’t hard to choose your outdoor silicone sealant. You first look to your area’s local climate. If it’s brutally sunny or cold, prioritize weather resistance. Then check if it’s compatible with the material to avoid damaging it. Then verify water and aging resistance along with strong adhesion. Then, choose the sealant according to your specific use.
