## Description

Need to fill or seal an expansion joint between two different materials? Everbuild Tecnic 825 Silicone Sealant is a low modulus formula designed with a long skinning time to give you a longer tooling time and the flexibility you need to finish the job. It's neutral cure and odourless, so you can feel confident using it indoors, and it's weatherproof for external use, as well. The adhesion is top tier as it suits both porous and non-porous surfaces, including brick, PVCu, glass and more. Simply clean the surfaces, check the joint width is no larger than 50mm wide and 25mm deep, and apply. Also available a range of colours, and white is also available as a 600ml foil.

## Features

- IDEAL FOR USE IN HIGH-MOVING JOINTS – The flexible and non-slump formula means it can be used in joints up to 50mm wide where there's a chance of expansion, such as pointing around doors and windows.
