Everbuild EB25 is a top-quality hybrid sealant and adhesive developed with cutting-edge technology...Everbuild EB25 is a top-quality hybrid sealant and adhesive developed with cutting-edge technology and a unique polymer blend. It offers extreme flexibility and is certified for indoor and outdoor use, as well as in sanitary and food preparation areas (ISEGA). This sealant is also exceptionally strong, adheres to most surfaces, and can even be applied underwater. Once cured, it provides resistance to mould, temperature extremes, chemicals, petrol, and UV radiation, while also being environmentally friendly. Its applications include sealing and bonding in various scenarios, acting as a high-quality nail replacement adhesive even to damp surfaces, perimeter pointing around doors and windows, bonding mirrors, sealing expansion joints, and jointing cladding panels. It is ideal for applications requiring high performance and durable sealing and bonding, as well as resistance to chemical spillage. Characteristics include incredible initial grab, no slip, and gap-filling properties, high bonding strength, suitability for interior and exterior use, and certification to harmonized European standards for facade and sanitary use. It can be applied to wet surfaces, is waterproof and weatherproof, and cures quickly. It is resistant to temperature extremes from -40°C to +100°C and chemicals like petrol (10% dilute acids/alkalis, most solvents). The sealant offers excellent primerless adhesion to most surfaces, including metals, plastics, glass, concrete, plaster, plasterboard, polyester, perspex, wood, enamel, and painted surfaces. It is also overpaintable with some paints (testing a small area first is recommended). Slump resistance is less than 3mm (ISO7390). Approvals and standards include CE Marking, EN15651-1: 2012 (Type F EXT-INT Class F20HMC), EN15651-3:2012 (Type S Class XS2), and Food Safe certification.
The Everbuild EB25 Ultimate Sealant Adhesive in White is designed for professionals and DIYers needing a high-performance, versatile solution for sealing and bonding in demanding environments. Its key benefit is extreme flexibility combined with exceptional strength and adhesion to most surfaces, even underwater. A potential caveat is that it may require testing with certain paints before full application.

Extended Product Information
FAQs
Can Everbuild EB25 be used for structural bonding?
Everbuild EB25 is primarily a sealant and adhesive. While it offers high bonding strength, it is not intended for structural load-bearing applications where primary structural integrity relies solely on the adhesive bond. Always consult product datasheets for specific application guidance.
How long does it take for Everbuild EB25 to cure?
Curing time depends on temperature, humidity, and bead size. Typically, it skins over in approximately 15-30 minutes and can be handled or overpainted after a few hours. Full cure can take 24-48 hours depending on conditions.
Is Everbuild EB25 suitable for use in food areas?
Yes, Everbuild EB25 has passed the ISEGA standard for use in sanitary and food preparation areas, making it suitable for applications where food contact is possible.
Can I apply Everbuild EB25 to a painted surface?
Yes, it adheres well to most painted surfaces. However, for optimal adhesion and to avoid potential peeling of the paint, it's recommended to lightly abrade the painted surface and ensure it is clean and dry. Always test compatibility on a small area first.
What is the temperature range for application?
Everbuild EB25 can be applied in temperatures between +5°C and +40°C. Once cured, it withstands temperatures from -40°C to +100°C.
How do I clean up excess EB25?
Uncured EB25 can be cleaned up using a damp cloth or appropriate solvent. Cured EB25 needs to be removed mechanically.
Is this sealant waterproof?
Yes, once fully cured, Everbuild EB25 forms a waterproof and weatherproof seal, making it suitable for interior and exterior applications.
Troubleshooting
Sealant not adhering well
Ensure surfaces are clean, dry (or appropriately damp for wet application), and free from dust, grease, or old sealant. Re-test adhesion on a small area if unsure about surface preparation or paint compatibility.
Sealant is stringy or difficult to apply
Ensure the product has been stored correctly and is within its shelf life. Check that the cartridge has not been punctured incorrectly. Use a steady, even pressure on the sealant gun.
Cured sealant shows mould growth
While EB25 has mould resistance, severe conditions may still allow growth. Clean the affected area thoroughly and ensure adequate ventilation. For persistent issues, consider a mould-inhibiting primer before re-sealing.
Overpainted surface is peeling
The paint used may not be compatible with the sealant. Remove the peeling paint, clean the sealant surface, and test a different type of paint on a small area before repainting the entire surface.
Pros and Cons
Pros
Extremely flexible and durable seal
Bonds to a wide range of materials, including damp surfaces
Suitable for interior, exterior, and sanitary applications
Resistant to extreme temperatures, UV, mould, and chemicals
Waterproof and weatherproof once cured
Environmentally friendly formulation
Cons
Overpainting may require prior testing for compatibility with specific paint types
Initial grab, while strong, might not be sufficient for all immediate load-bearing applications without temporary support
Requires a sealant gun for application (standard cartridge size)
Setup, Compatibility & Care
Setup:
Ensure the surfaces to be bonded or sealed are clean, dry (unless applying to damp surfaces for specific applications), and free from dust, grease, and other contaminants.
Cut the nozzle to the desired bead size.
Apply the sealant using a standard sealant gun.
For sealing joints, ensure adequate joint width and depth. Refer to technical data sheets for recommended joint dimensions.
Compatibility:
Surfaces: Excellent primerless adhesion to most surfaces including metals (aluminium, steel), plastics (ABS, PVC, polycarbonate), glass, concrete, plaster, plasterboard, wood, enamel, and painted surfaces.
Overpainting: Can be overpainted with most water-based and synthetic paints. Always test a small, inconspicuous area first to ensure compatibility and adhesion.
Standards: Certified to EN15651-1 (Facade) and EN15651-3 (Sanitary) standards.
Care:
Storage: Store in original unopened containers in a cool, dry place away from direct sunlight and frost.
Cleaning: Remove excess uncured sealant with a damp cloth or appropriate solvent. Cured sealant can be removed mechanically.
