Experience unmatched sealing precision with the Sikaflex®-15 LM and AWF Pro® 10 oz. Caulking Gun Kit, combining a high-performance, low-modulus polyurethane sealant with a durable, 18:1 thrust caulking gun. Perfect for dynamic joints in high-rise, facade, and Exterior Insulation Finish Systems (EIFS), this kit ensures seamless application for construction professionals tackling concrete panels, window/door frames, roofing details, and more.

Kit Includes

• Sikaflex®-15 LM Sealant (10.1 fl. oz. cartridge, select 12 or 24, white or limestone): A one-component, non-sag elastomeric sealant with +100/-50% movement capability (ASTM C-719), meeting ASTM C-920 Class 100/50 and TT-S-00230C standards. Offers superior adhesion to concrete, aluminum, and glass without a primer, plus weather and jet fuel resistance.
• AWF Pro® 10 oz. Caulking Gun: A robust manual caulking gun for 10.3 oz. cartridges, featuring an 18:1 mechanical advantage for effortless application of high-viscosity sealants. Includes a rotating barrel for corners, a seal-puncturing pin, thumb-activated pressure release, and a built-in ladder hook.

Applications

This kit is ideal for sealing dynamic joints in high-rise buildings, facades, and EIFS, as well as concrete wall systems, window/door perimeters, reglets, and roofing details. The AWF Pro Caulking Gun’s pivoting barrel ensures smooth application around corners and tight spaces, making it a must-have for professional contractors.

Application Guidelines

Apply Sikaflex-15 LM at 40°F–100°F to clean, dry, frost-free substrates, conditioning to 65°F–75°F for best results. Use the AWF Pro Caulking Gun to dispense sealant with a steady flow, maintaining a 2:1 width-to-depth ratio (1/4" min., 1/2" max. depth). Tool sealant for full joint contact and allow a 7-day cure before painting or water immersion.
