The Everbuild 450 Builders Silicone Sealant in Grey is designed for builders and DIY enthusiasts needing a versatile, high-performance sealant for a wide range of applications. Its key benefit is excellent adhesion to numerous surfaces without priming, offering a fast-curing, waterproof, and permanently flexible seal. A potential caveat is its specific formulation, which may require particular application techniques for optimal results.

It adheres to a wide range of porous and non-porous surfaces including PVCu, wood, painted surfaces, metal, glass, and masonry without the need for priming.
In most cases, no primer is required. However, for optimal adhesion on challenging surfaces or in highly demanding conditions, a primer may be beneficial.
It cures quickly, forming a permanently flexible seal. Drying time depends on application thickness and environmental conditions (temperature and humidity).
Yes, it cures to provide a permanently flexible, high-strength waterproof seal.
This sealant is generally not recommended to be painted over. It is designed to provide a finished aesthetic on its own.
This is a low-modulus sealant, meaning it has excellent flexibility and movement accommodation, making it suitable for joints that experience expansion and contraction.
Uncured sealant can be wiped away with a damp cloth. For stubborn residue, use a solvent cleaner suitable for silicone, testing in an inconspicuous area first.
Ensure the surface is clean, dry, and free from dust, grease, or old sealant. For porous surfaces, consider using a compatible primer.
Check that the cartridge has not expired. Ensure the nozzle is cut correctly and the sealant gun is functioning properly. The high viscosity is normal and aids in tooling.
Practice applying a consistent bead on a scrap surface. Use a wet tooling tool (spatula or finger dipped in soapy water) immediately after application to smooth the bead.
This is normal for oxime cure sealants. Ensure good ventilation in the work area during and immediately after application until the odor dissipates.
Setup: This sealant requires a standard silicone sealant gun for application. Ensure the cartridge nozzle is cut to the desired bead size and fitted to the gun.
Compatibility: It adheres to a wide range of surfaces including PVCu, wood, painted surfaces, metal, glass, and masonry without primer. However, always test on a small, inconspicuous area first, especially on plastics or painted surfaces, to ensure compatibility and avoid discoloration. It is not recommended for use on silicone, rubber, or asphalt.
Care: Surfaces must be clean, dry, and free from dust, grease, and old sealant. For porous surfaces, a suitable primer may enhance adhesion. After application, tool the bead immediately with a wet spatula or tool for a neat finish. Avoid exposing the applied sealant to water until fully cured.
