Product info

The Avenir Universal Sealant is a high - performance, versatile sealing solution designed for both indoor and outdoor applications. This flexible sealant adheres effectively to a wide range of materials, including wood, metal, glass, as well as various plastics. 

With its superior weather resistance, it provides long - lasting protection against moisture, and temperature fluctuations. This Universal Sealant is a black, waterproof, silicone suitable for creating a long-lasting seal on chases above wall trims. Each cartridge contains approximately 300 ml and covers up to 3 linear metres to create a seal on large existing chases, with only a small bead of sealant being needed.

The sealant cures quickly, forming a durable waterproof barrier, preventing leaks and drafts. It is easy to apply, ensuring a smooth finish that can be painted over if desired. Ideal for use in construction and home repairs, Avenir Universal Sealant offers excellent adhesion, elasticity, and durability, making it an essential tool for professional and DIY use.
