Soudal LM Silirub Silicone Sealant Low Modulous -300ml

Soudal Silirub LM – Low Modulus Neutral Cure Silicone Sealant (300ml)

Soudal Silirub LM is a professional-grade, low modulus, neutral curing silicone sealant, specially designed for high-movement joints in both internal and external applications. It forms a flexible, elastic joint after curing, making it ideal for expansion joints, building joints, and glazing work.

This versatile sealant offers outstanding adhesion to a wide range of non-porous materials, including PVC, treated timber, glass, and metal, without the need for primer. It’s UV-resistant, colourfast, and remains permanently elastic, even under temperature extremes.

Suitable for professional construction, window fitting, and façade sealing projects, Silirub LM is available in a range of colours to match common construction materials.
