Construction Silicone Sealant Soudal Silirub N White 310 ml

Soudal Silirub N White 310 ml is a neutral-curing construction silicone sealant formulated for durable, flexible joints in sanitary, window, door and general building applications. Supplied in a 310 ml cartridge, this white silicone bonds to glass, glazed ceramics and many common building substrates while remaining weather-resistant and flexible after curing. It is intended for both interior and exterior use where a neutral cure is required to avoid staining sensitive surfaces and to ensure broad material compatibility.

Advantages

The neutral cure formulation reduces the risk of corrosion and staining on metal and sensitive substrates and provides reliable adhesion to glass and glazed surfaces. Once cured it delivers long-lasting elasticity and weather resistance, maintaining joint integrity under temperature variation and mechanical movement. The 310 ml cartridge format is compatible with standard caulking guns for controlled application and neat finishing.

Suitable for

• Sealing joints around windows and doors
• Sanitary joints in bathrooms and kitchens where neutral cure is preferred
• Sealing around glazed ceramics and glass surfaces
• General building joints and connections exposed to weather

When it may not be suitable

This neutral silicone is not designed for load-bearing structural applications or for adhesives requiring high shear strength. It may not adhere well to certain plastics, polyethylene, polypropylene or bituminous substrates without appropriate priming. For situations requiring paintability, many neutral silicones are not paintable — verify paint compatibility before use.

Key specifications

• Color: White
• Volume: 310 ml cartridge
• Cure type: Neutral (oxime-free) silicone
• Application temperature range: Suitable for typical indoor and outdoor temperatures (check product label for exact limits)
• Properties after curing: Flexible, weather-resistant seal

How to use

Prepare surfaces by cleaning away dust, grease and loose material and ensure surfaces are dry. Cut the cartridge nozzle to the desired bead size and load into a standard caulking gun. Apply a continuous bead into the joint, then tool the sealant within the skin time to obtain a smooth finish and good contact with joint sides. Allow full cure time as specified on the product packaging before exposing to sustained moisture or movement.

What to consider before purchase

• Confirm color and volume (white, 310 ml) suit the intended application
• Check substrate compatibility, especially non-porous plastics and bituminous materials
• Verify whether neutral-cure silicone is required to prevent staining or corrosion on adjacent materials
• Consider required cure time and expected joint movement to ensure performance

Usage recommendations

For best results, use Soudal Silirub N on clean, dry surfaces and tool joints within the product's working time. Store cartridges in a cool, dry place and use a primer where manufacturer guidance indicates limited adhesion. Follow safety instructions on the packaging and allow sufficient cure time before exposing the sealed joint to water or mechanical stress.
