Adhesive Primer OTTOFLEX®
Adhesive Primer OTTOFLEX®
OTTOFLEX® Adhesive Primer is a premium, solvent-free synthetic resin dispersion based on styrene butadiene. It serves as a high-strength, adhesion-enhancing primer and bonding course for both floor and wall areas indoors and outdoors. Engineered for versatility, it creates a highly secure bond with water-based thin-bed mortars and coatings across a wide variety of substrates, ranging from hydraulically hardening cement to glazed ceramic tiles, steel, and glass.
👷♂️ The Master Tiler's Verdict
"This primer is an absolute essential when you are tiling over existing, smooth, or sealed substrates like glazed ceramics or steel. Because it boasts a very short, 1-hour drying time on non-absorptive surfaces, it keeps jobs moving fast. Even better, on absorptive substrates, there is no drying time at all—you can apply your subsequent coatings while it is still wet."
Pro Trade Tip: Always stir or agitate well before use and apply with a lambswool roller. Use the primer undiluted on non-absorptive substrates, but you must dilute it 1:1 with water on absorptive substrates. If applying outdoors or in wet areas, the primer coating must be protected by a suitable composite sealing like OTTOFLEX Protective coating or Slurry seal coating.
