If you're installing or replacing coping stones on garden walls, parapets, or boundary structures, the Castle Composites Two Part Coping Stone Adhesive is the ideal product to get the job done properly. This 6kg polyurethane-based adhesive has been specially formulated to provide a strong, durable bond between coping stones and the surface beneath.
Designed for both professional landscapers and competent DIYers, this two-part adhesive offers a hassle-free solution for securing coping stones with confidence—whether on new builds or refurbishment projects.
Simple Mixing and Application
The adhesive is supplied in two separate components—Part A and Part B. To activate it, simply mix the full contents of both parts together until the mixture reaches a consistent colour. This ensures the bonding agents are fully combined for optimal performance.
You can apply the adhesive using a notched trowel for even distribution, or by buttering the back of the coping stone directly. Be sure to wear gloves during the process, as the adhesive is a chemical product and can irritate skin.
Fast Curing for Efficient Projects
Once applied, the adhesive takes approximately 24 hours to fully cure, providing a strong, weather-resistant bond that will keep your coping stones secure in all conditions. It’s an ideal choice for both indoor and outdoor projects where reliability and ease of use are essential.
For your safety and peace of mind, a downloadable safety data sheet is available, offering full guidance on safe handling, storage, and application procedures.
