Questions and Answers:

Geocel 945 FAQs

1. What types of construction joints are suitable for Geocel 945 HM Sealant & Adhesive?
Designed for a wide variety of joints that experience regular or dynamic movement. This includes expansion joints in walls, floors, and facades, as well as control joints used to manage shrinkage or thermal expansion in concrete and masonry. Its high movement capability ensures it can flex and absorb these shifts without cracking. It is also suitable for bonding joints in cladding and curtain wall systems, offering both sealing and adhesive functionality in one product.

2. How does Geocel 945 HM withstand different weather conditions?
This hybrid polymer sealant is formulated to endure extreme environmental factors. It is resistant to prolonged UV exposure, preventing deterioration and yellowing under direct sunlight. The sealant is also waterproof and can withstand heavy rain, humidity, and freeze-thaw cycles, making it suitable for both interior and exterior applications. Its elasticity ensures that it maintains performance even under fluctuating temperatures, which can cause building materials to expand and contract.

3. What materials are compatible with Geocel 945 HM, and are there any limitations?
Adheres to a wide range of building materials, including concrete, stone, brick, metal (e.g., aluminium, steel), and wood. It can also bond to certain plastics, depending on surface preparation. For optimal adhesion, it is recommended to clean the surfaces thoroughly and apply a primer if necessary. The sealant is not intended for use on non-porous surfaces that are permanently submerged in water, such as pools or aquariums.

4. How can I maximise adhesion and performance when applying this sealant?
To achieve optimal adhesion, begin by ensuring that all bonding surfaces are clean, dry, and free from contaminants such as grease, dust, and loose debris. Use a solvent cleaner for stubborn residues if needed. Cut the nozzle at the correct size for your joint and apply the sealant in a continuous, even bead. Immediately tool the sealant to ensure full contact with the joint surfaces. For large or critical applications, using a compatible primer can further enhance adhesion.

5. Can Geocel 945 HM be painted over, and what types of paint are compatible?
Yes, once fully cured, it can be painted with most water-based (emulsion) and solvent-based paints. To ensure a seamless finish, it is important to allow the sealant to cure completely, which typically takes 24-72 hours. For best results, conduct a small patch test to verify paint compatibility and adhesion. Avoid using paints that may crack under joint movement, as the sealant's flexibility could affect the paint layer's integrity over time.
