Neutral Silicone (Soudal)

The Soudal Neutral Silicone is a high-quality, multi-purpose sealant designed for professional sealing applications across a wide range of surfaces. Suitable for use with uPVC, aluminium, glass, and other common building materials, it provides a strong, flexible seal that maintains its performance over time.

Available in White, Black, Anthracite Grey and Clear, this silicone is ideal for matching modern window frames, trims, cladding, and general finishing work. Its neutral cure formula ensures low odour and excellent adhesion without damaging sensitive materials, making it suitable for both internal and external use.

Application is simple using a standard sealant gun — apply evenly along the joint and smooth off for a clean finish. Once cured, it forms a durable, weather-resistant seal that resists cracking, shrinking, and discolouration.
