Why CT1 Is One of the Best Sealants on the Market
Choosing the right sealant can make a big difference in how well a job holds up over time. CT1 is widely used across the trade because it is simple to use, reliable, and built to handle a wide range of tasks.

Works in Most Conditions
One of the key benefits of CT1 is that it works in situations where other sealants struggle. It can be applied to damp surfaces and still performs well, which is ideal for outdoor jobs, kitchens, bathrooms, and construction work.
This means you don’t have to wait for perfect conditions to get started. It helps speed up jobs and makes it a practical option for both professionals and DIY users.
Strong but Flexible
CT1 creates a strong bond, but it also stays flexible once cured. This is important because materials naturally move over time due to temperature changes and general use.
Instead of cracking or failing, CT1 moves with the surface. This helps extend the life of the repair and reduces the need for ongoing maintenance.
Easy to Use Across Different Jobs
Another reason CT1 stands out is its versatility. It can be used for sealing, bonding, and general repairs, meaning you don’t need multiple products for different tasks.
This makes it a convenient option to keep on hand, whether you’re working on a building site or carrying out jobs around the home.
Clean and Tidy Finish
CT1 provides a neat finish that holds its appearance over time. It performs well in both indoor and outdoor environments.
This is especially useful for visible areas where a clean, professional look is important.
