Description
Soudal LMN Brown Silicone Sealant 300ml
Soudal LMN Brown is a professional neutral cure silicone sealant for glazing, frames, joints, and exterior sealing. It gives a neat brown finish and stays flexible after curing. Soudal describes Silirub LMN as a superior quality low modulus neutral cure silicone with primerless adhesion on common construction materials, high movement capability, and resistance to UV, rain, snow, and temperature extremes.
Key Features
This sealant offers low modulus performance for moving joints and perimeter seals. It applies neatly, tools well, and suits common building surfaces including glass, plastics, masonry, metals, and wood. Merchant listings for code 117859 also describe it as a general purpose neutral cure brown building silicone in a 300ml cartridge.
Applications
Use this silicone for window frames, door frames, glazing joints, perimeter sealing, façade work, and general construction sealing. It is a good option where you need a brown seal around darker trims, timber-effect finishes, or external joints. As a result, it works well for both new installations and repair jobs.
Colour Match
The Brown finish is useful for timber-look frames, darker trims, and visible external joints where white or clear sealant would stand out too much. In many cases, it gives a neater and more professional finish around frame edges and perimeter lines. Multiple UK merchants list code 117859 specifically as the brown version of Soudal’s neutral cure low modulus silicone.
Pack Size Options
This product is supplied in a 300ml cartridge and can be sold as 1 tube or box quantity depending on how you want to structure the listing. Apply it to clean, dry, dust-free surfaces with a standard sealant gun. Smooth the bead before skinning begins, and test first on unfamiliar surfaces.
