How to Use Geocel 925 NS Sealant

1. Surface Preparation: Clean and dry all surfaces, ensuring they are free of dust, grease, and contaminants. For sensitive materials like marble, avoid harsh cleaning agents.
2. Nozzle Cutting: Trim the nozzle to your desired bead size at an angle and attach it securely to the cartridge or foil pack.
3. Load the Cartridge: Insert the cartridge into a compatible caulking sealant gun for smooth application.
4. Backing Material: Apply the backer rod or bond breaker
5. Sealant Application: Apply a continuous bead along the joint, ensuring full surface contact.
6. Tooling: Smooth the bead immediately using a tooling stick or spatula to create a clean, even finish.
7. Curing: Allow the sealant to skin over within 30-60 minutes. Full curing may take several days depending on joint size and environmental conditions.

1. Can Geocel 925 NS be used for both new builds and restoration projects?
Yes, Geocel 925NS Non-Staining Sealant is ideal for both modern construction and restoration projects. Its neutral-cure, non-staining formula ensures that it preserves the natural appearance of sensitive materials like marble, granite, and limestone, making it perfect for heritage and historic buildings. Additionally, the sealant offers excellent flexibility and weather resistance, making it equally suitable for sealing dynamic joints and perimeter openings in new builds. Its compatibility with both porous and non-porous surfaces ensures effective performance across a wide range of applications.

2. What are the advantages of using a non-staining sealant on natural stone surfaces?
Conventional sealants can release oils, solvents, or other chemicals during the curing process, which can penetrate and stain natural stone surfaces. This can result in permanent discolouration and compromise the aesthetic of high-value materials like marble and granite. Geocel 925 NS is specifically designed to prevent this issue. Its advanced neutral-cure formula does not produce by-products that could damage or stain stone surfaces. This makes it a preferred choice for both architects and contractors working on projects that require pristine stone finishes.

3. How does this sealant maintain flexibility over time?
Geocel 925 NS is formulated with elastic polymers that allow it to absorb and adapt to movement in joints. This flexibility helps it handle structural shifts, thermal expansion, and mechanical vibrations without cracking or losing adhesion. Over time, external factors like temperature changes, wind loads, and building settlement can cause joints to expand and contract. The sealant’s long-term flexibility ensures that it accommodates these movements, preventing joint failure and extending the lifespan of the seal.

4. Can Geocel 925 NS provide protection against environmental factors?
Yes, Geocel 925NS offers excellent resistance to environmental conditions, including prolonged exposure to UV radiation, rain, and extreme temperatures. This makes it highly suitable for exterior applications, such as sealing stone façades, expansion joints, and perimeter gaps. The sealant creates a weatherproof barrier that prevents water and air infiltration, which helps protect both the structural integrity of the building and the aesthetic quality of the stonework. Additionally, its UV stability prevents degradation, ensuring long-lasting performance in outdoor environments.

5. What preparation is required before applying Geocel 925 NS sealant?
Proper surface preparation is crucial to achieve optimal adhesion and performance. Before applying ensure that all bonding surfaces are clean, dry, and free from dust, grease, and old sealant residues. For natural stone surfaces, it is important to avoid using aggressive chemical cleaners that could damage or etch the surface. Use a clean, lint-free cloth or brush to remove any debris. Once the surface is prepared, the sealant can be applied smoothly with a caulking gun. For best results, tool the joint immediately after application to create an even, professional finish. Allow sufficient time for curing based on environmental conditions.
