Sikaflex Construction ⁺ is a one-component, flexible polyurethane putty, which sets under the influence of moisture. For indoor and outdoor use.

Features

• flexible
• odorless
• solvent-free
• very good aging resistance
• very good resistance to weather conditions
• excellent adhesion to various substrates
• very low emissions
• permissible deformation 35% (ASTM C 719)
• cures without microbubble gas evolution
• innovative surface - with a delicate structure (dry-finished joint) or smooth (wet-finished joint)
• easy to apply and level out

Application

The product is used for sealing in construction, for sealing and filling on brick and concrete facades, e.g. for window sills, balconies, sealing around doors and windows, concrete and steel cladding, for steel, wooden, brick and PVC elements.
