Sika Sikaflex NP1 in Stone is a contractor-grade polyurethane construction sealant supplied as a 20 oz sausage pack for bulk caulk guns. The stone color is designed to blend with masonry, brick, and concrete tones, making it a great choice for exterior veneer work and clean joint lines on architectural surfaces.
NP1 cures to a durable, elastic seal that flexes with seasonal expansion and contraction to help reduce cracking along joint edges. Use for expansion joints, control joints, and perimeter sealing on properly prepared concrete, masonry, metal, and wood. The sausage pack format supports long joint runs with fewer reloads, improving productivity on jobsite sealing.
