When it comes to silicone sealants used in swimming pools and marine environments, we have a wide range available and always offer free expert advice on which would be the best for your needs. 

100% silicone sealants 

These sealants are commonly used in swimming pools and marine environments due to their excellent UV resistant and water repelling properties. They provide a permanent elastic seal that withstands constant exposure to water and weather conditions. 

Waterproof silicone sealants 

This type of silicone sealant is specifically designed for use in wet areas, including swimming pools. It offers high water resistance and forms a durable seal that prevents leaks and moisture penetration. Their unique composition gives them a particularly high resistance to fungal attack. 

Neutral cure silicone sealants 

Neutral curing silicone sealant cures without releasing any acidic or corrosive byproducts whilst still offering very good resistance; making them suitable for use in sensitive environments like swimming pools and marine structures. They offer good adhesion to various surfaces, have high chlorine resistance and provide long-lasting sealing properties. 

Epoxy silicone hybrid sealants 

These sealants combine the benefits of epoxy and silicone, offering excellent adhesion and durability. They are often used in marine environments where high strength and resistance to water and chemicals are required. 
Our silicone services are not only designed to offer a barrier of protection to frequently wet areas but also to offer seamless integration with their aesthetic. We offer a wide selection of swimming pool sealants in various colours to effectively seal and match different substrates, creating the desired aesthetic.
