Last in our silicone survival guide, but certainly not least, is Soudal Silirub 2 🟠
Silirub 2 is a premium quality, low modulus, neutral cure silicone that provides the flexibility needed for outdoor bird spike installations.
Because it remains elastic after curing, it can accommodate movement caused by changing temperatures and different building materials, helping to reduce the risk of cracking or the spike base becoming detached.
Its thick bodied formula offers excellent workability, while its neutral curing system is virtually odourless and non corrosive. It also provides primerless adhesion to many common building surfaces.
Colourfast, UV stable and highly resistant to weathering, Silirub 2 is a reliable choice for installations exposed to the elements throughout the year.
Swipe through the carousel to discover what makes Silirub 2 different and when you might choose it for your bird spike installation.
Always begin with a clean, dry surface that is free from dust and grease. We also recommend fixing one test section and leaving it for 24 hours before completing the installation.
