👷 📋 The Master Tiler's Verdict

"When you're installing high-end matte tiles or modern matte black/brass fixtures, standard glossy silicone ruins the aesthetic. The S 100 Matt line is my absolute go-to for contemporary bathrooms. It blends seamlessly with non-reflective surfaces while offering the unbeatable mould resistance OTTO is famous for."

Pro Tip: To preserve the perfect matte finish, only tool the joint once with your smoothing agent. The more often the surface is reworked, the more the matte effect is lost and the joint becomes glossier.
