Why Silicone Remains One of the Construction Industry’s Most Relied-Upon Materials

Since the 1950s, silicone has been one of the construction industry’s most relied-upon materials. What began as a novel sealant technology quickly became indispensable, finding its way into almost every trade toolbox around the globe.

Today, plumbers, builders, electricians, tilers, flooring specialists, roofers and countless DIY enthusiasts depend on silicone for reliable sealing, bonding and long-term protection across a wide range of applications.

Soudal has long recognised the importance of high-performance silicones for trade professionals. Our extensive silicone range is designed to deliver consistent results on site, offering trusted solutions for critical tasks such as sealing around tiles, sinks, baths, showers, toilets and anywhere long-lasting water resistance is essential.

Silicone Performance for Movement, Weather and Long-Term Durability

Silicones also excel when sealing doors and windows because they are made from silicone polymers that cure by reacting with moisture in the air, forming a flexible, rubber-like material capable of withstanding continuous movement. This high elasticity makes silicone ideal for joints and seams exposed to expansion, contraction and vibration, ensuring the seal remains intact over time.

One of silicone’s greatest strengths is its resistance to the elements. It performs reliably under extreme temperatures, UV exposure and moisture, making it a go-to choice for any outdoor use. It also adheres exceptionally well to non-porous surfaces such as glass, metal, ceramic and many plastics.

However, silicones are not paintable and may require primers when used on porous or unsealed substrates like timber or concrete. If you do want a paintable finish, a hybrid polymer sealant is a better choice.

Silicone vs Hybrid Sealants: Soudal’s SMX® Innovation

This is where Soudal’s innovation sets us apart. Our company has taken hybrid technology beyond traditional MS polymers by developing our advanced SMX® formulation (Soudal Modified Extensions). SMX® is found in our T-Rex, FixAll, Multibond and Soudaseal ranges, and combines the best characteristics of multiple polymer families, including silicone, polyurethane and acrylics.

Together, Soudal’s silicones and SMX® hybrid polymers give trade professionals a complete toolkit, flexibility where it matters, strength when it counts and solutions tailored to the realities of modern construction. Every year, Soudal produces 333 million units of sealants, sold worldwide, reinforcing our scale, experience and technical expertise.

Professional Finishes: The Right Tools Matter

Lastly, to achieve a professional finish, having the right tools is just as important as choosing the right silicone. Soudal’s Sealant Spatula Kit is designed for trade-quality results, featuring seven sizes to suit any application. With different angles for finished edges, it allows users to create smooth, precise seals that look as good as they perform. Beyond aesthetics, using the spatula also helps maintain hygiene and reduce the risk of mould growing by eliminating the need to smooth silicone with your fingers.

For anyone serious about long-lasting, high-quality results, using the right silicone and the right tools will make all the difference. Soudal has the professional solution you are looking for.

FAQs

Which silicone should I use for bathrooms, kitchens and other wet areas?

For wet areas exposed to regular moisture, a sanitary silicone such as Soudal Bathroom & Kitchen is recommended. It’s formulated to limit mould and bacterial growth while maintaining long-term water resistance.

What silicone is best for outdoor use and weather exposure?

Outdoor applications require a silicone with high UV and weather resistance. Products like Soudal Roof & Gutter are designed to perform in extreme temperatures and prolonged sun exposure.

Can silicone be used on roofs and gutters?

Yes. Roofing and gutter applications require a high-adhesion, UV-resistant silicone that can handle movement and weather exposure. A neutral-cure silicone designed for roofing materials is recommended.

Is silicone paintable?

 No, silicone is not paintable. If a paintable finish is required, a hybrid polymer sealant using SMX® technology is a better alternative.

Why does choosing the right silicone matter for different jobs?

Different applications involve different substrates, movement levels and exposure conditions. Using the correct silicone improves adhesion, durability and long-term performance, reducing the risk of failure on site.
