Hybrid Adhesive/Sealant OTTOCOLL® M501 Premium
Engineered by OTTO-CHEMIE, OTTOCOLL® M501 Premium is the premier crystal clear hybrid adhesive and sealant designed for professional tilers, contractors, and trade specialists across Ireland. Delivering completely transparent, invisible bondings with zero grease migration on natural stone, it provides robust elasticity and exceptional performance across sensitive architectural and finishing applications.
👷♂️ The Master Tiler's Verdict
"When you're installing glass splashbacks, decorative mirrors, or premium natural stone where any glue line would ruin the finish, M501 is the only crystal-clear hybrid I trust. It doesn't leave greasy residue on marble, grips firmly even on slightly damp surfaces, and stays permanently elastic without yellowing."
Pro Trade Tip: For porous substrates like concrete, plaster, or untreated wood, always prime with OTTO Primer 1105 to provide an alkaline moisture barrier and guarantee maximum long-term adhesion.
Why Irish Trade Professionals Choose OTTOCOLL® M501
- Crystal Clear Transparency: Formulated specifically for inconspicuous, virtually invisible bonds where aesthetics are paramount (glass, transparent plastics, and clear displays).

- Damp Surface Adhesion: Excellent bonding performance on slightly damp substrates without losing working time or bond strength.
- Permanent Elasticity: High movement accommodation factor capable of compensating for thermal expansion and dynamic mechanical stress between dissimilar materials.
- Safe Chemical Profile: Completely free of silicones and isocyanates, making it low-odour, highly health-safe, and EMICODE® EC 1 Plus certified for ultra-low emissions.
- Broad Substrate Versatility: Superior primerless adhesion on glass, metals (aluminium, stainless steel), plastics (PVC, PMMA), ceramic, wood, and mineral building materials.
