Key Specifications:
CT1 is well-known in the trade sector for its hybrid polymer formula, designed for construction and repair work. It bonds to a range of substrates and performs well under water. However, its thicker consistency and slower cure time may not suit every project – and it comes at a premium price point.
Key Specifications:
Everbuild Stixall is a versatile option. It boasts good initial grab and sticks to almost everything. However, it can be difficult to work with due to its high viscosity, and users often report excessive stringing during application.
Key Specifications:
UniBond offers a range of sealants for DIY and light trade use. While accessible and available in most retail stores, it’s generally designed for light-duty sealing rather than heavy construction applications. Not ideal where maximum strength or weather resistance is required.
Key Specifications:
A reliable name in industrial-grade adhesives, Sika’s Sikaflex EBT+ provides solid all-round performance. It adheres well to common building materials and resists vibration and weathering. However it isn’t suitable for high-clarity finishes.
