Soudal Silirub 2 Neutral Low Mod Silicone Sealant Builders Construction 24 Colours

Soudal Silirub 2 Neutral Low Modulus Builders and Construction Silicone Sealant Available in a large range of 24 Colours

Overview:

Soudal Silirub 2 is a premium neutral cure, LM silicone sealant manufactured from 100% pure silicone, designed for professional building and construction sealing. It skins quickly, cures without shrinkage and has a thick-bodied consistency that makes it easy to gun and tool into a clean, reliable joint. Built for long-term flexibility.

Silirub 2 is ideal for perimeter sealing around window and door frames, movement and expansion joints, and general construction joints where you need a weatherproof finish that keeps performing over time. With primerless adhesion on many common building materials and a wide 24-colour range, it’s a practical choice when you want the seal to blend in with surrounding finishes.

Silirub 2 – Key FAQs

• Is Silirub 2 a neutral cure silicone?
  Yes, it’s a neutral cure silicone designed for broad construction use on many common materials.

• What does low modulus mean?
  Low modulus silicone stays more flexible, helping the joint cope with movement without cracking.

• Can I use it outdoors?
  Yes, it’s resistant to weathering, UV and temperature changes for exterior sealing.

• Can it be used on natural stone?
  No, it’s not recommended for natural stone due to potential leaching choose a stone-safe silicone instead.

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.
