Sealant Soudal Silicone Universal 310 ml — brown, cartridge 310ml

Soudal Silicone Universal 310 ml in brown is a neutral-curing silicone sealant formulated for sealing, bonding and finishing joints and gaps in building and renovation projects. The cartridge contains 310 ml of elastic, weather-resistant material suitable for interior and exterior use where a neutral cure is required. It adheres well to glass, glazed surfaces, ceramics, many metals and painted substrates, providing a flexible seal that accommodates joint movement and resists moisture and atmospheric influences.

Advantages

The sealant cures without releasing acetic acid, reducing the risk of corrosion on sensitive materials and preventing unpleasant vinegar-like odors during application. It forms a durable, elastic seal that maintains adhesion under thermal expansion and contraction. Its brown color matches common wooden and painted finishes, enabling discreet joints in visible areas. The product is suitable for both sanitary and exterior applications due to its resistance to weathering and mould growth in normal conditions.

Suitable for

• Sealing window and door perimeters
• Finishing skirting and trim joints
• Sanitary sealing around sinks, bathtubs and showers
• Exterior joints between cladding panels and frames
• Bonding glazed ceramics and glass to many substrates

How to use

Prepare joint surfaces by ensuring they are clean, dry and free of dust, grease or loose particles. Cut the cartridge tip to the required bead size and fit a compatible applicator gun. Apply the sealant evenly into the joint, avoiding air pockets, and tool the bead within the product's tack-free time to achieve a smooth finish. For deep joints, use a suitable backer rod to control sealant depth and allow correct joint movement. Allow the sealant to fully cure according to ambient temperature and humidity before exposing to water or heavy loads.

Usage recommendations

For best results, store cartridges at moderate temperature and apply between recommended substrate and ambient temperature ranges. Do not use on polyethylene, polypropylene, bituminous surfaces or surfaces that bleed oils or plasticizers. Test adhesion on painted surfaces if compatibility is uncertain. Follow standard safety measures: ventilate the work area and avoid skin contact.
