Overview: 

If you’re using silicone day-in, day-out, the Soudal Silirub 2 Trade Box of 15 is the practical way to stay stocked for ongoing building and maintenance work. This is the same premium neutral cure, low modulus Silirub 2 sealant, supplied in a bulk pack for better site value and fewer interruptions. Made from 100% pure silicone, it’s formulated to skin quickly, cure cleanly without shrinkage, and remain permanently flexible so joints can cope with regular expansion and contraction.

It’s a reliable choice for perimeter sealing around windows and doors, general construction joints and movement joints on many common substrates plus the 24-colour range makes it easier to match frames, trims and surrounding finishes across multiple jobs.

Key Features

• Trade Box of 15 – ideal for contractors, site stores and maintenance teams

Important Use Note

• Not for use on natural stone — leaching may occur. Use a stone-safe silicone for marble, granite and other porous natural stone.

Applications

• Perimeter sealing around window and door frames

• Expansion and movement joints in general construction

• Weather sealing and joint sealing on suitable building materials

• Maintenance and refurbishment sealing where long-term flexibility is required

How to Use

• Clean and dry the joint faces; remove dust, grease and old sealant

• Mask edges for sharper lines if required

• Apply an even bead and tool promptly to the desired profile

• Allow to cure fully before heavy water exposure or cleaning

• Test adhesion on unusual coatings/substrates before full application

Silirub 2 (Box of 15) – Key FAQs

• Why buy the box of 15?
  Lower cost per cartridge, fewer re-orders, and you’ll always have stock ready for repeat sealing work.

• Is it suitable for exterior sealing?
  Yes, it’s designed to resist weathering, UV and temperature extremes for outdoor joints.

• What does “low modulus” mean in practice?
  It stays more flexible, so it’s better suited to joints that move rather than rigid/static joints.

• Can I use it on natural stone?
  No use a dedicated natural-stone silicone to avoid staining or leaching issues.
