Description
Structural-strength epoxy in a ready-to-use cartridge. Tenax Domo 21 delivers the same permanent bond strength as Domo 10 — one of the strongest epoxies in the stone industry — in a pre-dosed 215ml cartridge for precise, mess-free dispensing on the jobsite or in the shop. Bonds to almost any surface including polished stone, damp substrates, ceramic, and concrete. The stone will break before the bond fails.
