Product Overview
Everbuild Premium+ 450 Builders Silicone supplied in a 300ml cartridge is a low modulus, neutral cure silicone sealant engineered for general construction, perimeter, and façade applications.
It provides excellent adhesion to a wide range of building materials including glass, metal, wood, PVCu, and polycarbonate, forming a durable, flexible, and weather-resistant joint. The non-corrosive formulation ensures compatibility with sensitive metals such as copper, zinc, and lead, while maintaining long-term elasticity under movement conditions up to ±25%.
Ideal for internal and external perimeter pointing, expansion joints, and panel sealing, it performs reliably in all building environments.
The brown colour offers a warm, complementary tone for use with timber, brick, and darker architectural finishes.
Features & Benefits
- Neutral Cure Formulation: Non-corrosive chemistry suitable for use on metal, glass, and composite substrates without surface damage.
- Low Modulus Flexibility: Accommodates joint movement up to ±25% for reliable long-term sealing in dynamic joints.
- High Adhesion Strength: Bonds securely to glass, metals, plastics, wood, and painted or coated surfaces without priming in most cases.
- Weather and UV Resistant: Maintains flexibility and appearance under long-term external exposure and temperature variations.
- Paint Compatibility: Resistant to plasticiser migration, suitable for use with both water-based and solvent-based paints.
- Brown Colour Finish: Provides a rich, natural joint line ideal for use with timber frames, brickwork, and brown-toned cladding systems.
Applications
- Perimeter Pointing: For sealing around PVCu, timber, and metal window and door frames, both internally and externally.
- Expansion Joints: Suitable for general building joints requiring long-term flexibility and weather durability.
- Panel and Façade Sealing: Used for sealing joints between pre-formed panels and building elements.
- Roof and Parapet Sealing: Ideal for waterproofing junctions and terminations on parapets, flashings, and roofing systems.
- Glazing Applications: Suitable for glass-to-glass, glass-to-aluminium, and glazing repair work.
- Metal and Leadwork: For sealing joints in soft metals including lead, copper, and zinc without corrosion risk.
Installation Guidance
- Surface Preparation: Ensure surfaces are dry, clean, and free from dust, oil, or loose material prior to application.
- Priming: Generally not required; if adhesion is uncertain, test a small area before full use.
- Application Method: Apply using a standard sealant gun; cut nozzle to the joint width and tool within 10 minutes for a smooth finish.
- Joint Design: Depth should not exceed 50% of the joint width; use backer rod where necessary.
- Finishing: Smooth with a wetted spatula to ensure full joint contact and a neat appearance.
- Cleaning: Remove uncured material with white spirit; cured material must be removed mechanically.
Compliance & Performance
- Material Type: Neutral cure, low modulus silicone rubber.
- Movement Capability: ±25% for expansion and contraction tolerance.
- Temperature Resistance: Suitable for use in typical construction environments and exterior exposures.
- Weathering Resistance: Excellent UV and moisture stability for long-term outdoor use.
- Adhesion Performance: Bonds effectively to glass, wood, metals, PVCu, and composite materials.

How delivery works
We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.
Delivery areas
Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.
If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.
What to expect on delivery day
- Deliveries are typically kerbside.
- Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
- Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.
Why delivery can cost more than typical parcel delivery
Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.
Returns
Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.
