Tenax TeFill 3 — Activator Pump, 2 oz

Tenax TeFill 3 Activator Pump is the essential curing component of the TeFill Stone Repair System. Without it, TeFill 1 and TeFill 2 cyanoacrylate adhesives cure slowly on their own — TeFill 3 triggers an instant chemical reaction that locks the repair in seconds. Apply the adhesive first, spray TeFill 3 over it, and the repair is solid. Once cured, sand and polish to a seamless, nearly invisible finish.

The precision pump applicator delivers controlled, targeted spray with minimal waste — no overspray, no mess. A must-have for any professional stone repair toolkit.
