Hybrid Adhesive & Sealant OTTOCOLL® M550 HiTack Premium
Engineered for professional tilers, stone fabricators, and commercial contractors who cannot afford downtime on site, OTTOCOLL® M 550 HiTack is a professional-grade 1-component hybrid polymer (STP) adhesive featuring phenomenal initial grab. Designed specifically for demanding vertical and overhead bonding applications, it eliminates the need for mechanical props or temporary fixations in most standard installations.
Whether you are mounting heavy natural stone window sills, large-format wall panels, stair treads, or mirrors, M 550 combines immediate holding power with permanent elasticity—completely free from isocyanates and silicones, and 100% safe for sensitive natural stone.
🛠️ The Master Tiler's Verdict
"When you're hanging heavy natural stone thresholds or vertical wall cladding, slip is your worst enemy. M 550 HiTack grabs instantly on contact—around 250 to 280 kg per square meter of initial adhesion—meaning no propping up, no waiting around, and zero risk of staining porous marble or granite. It's an absolute game-changer for high-end fit-outs."
