illbruck SP523

SP523 is a one-component, non-sagging sealant based on hybrid polymers. It is recommended for construction sealing such as joints in fa├žades, rainscreens and curtain walls; perimeter joints around windows, doors and rooflights; and high movement joints. It can be used for indoor and outdoor applications.

Packaging: 310ml cartridges or 400/600ml sausages
Colour: White, grey, ivory and black

Compatible with most common construction materials. Joint faces should be clean, dry and free from dust, oil, grease, old sealant and any traces of contaminant which may affect adhesion. Any previously applied sealant must be mechanically removed. Movement joints should be back filled with a foam backer rod such as FGT BR135 in order to control the depth of sealant and prevent three-sided adhesion.
