APPLICATIONS
Cut tip off cartridge / sausage with a sharp knife. Cut nozzle at 45° angle to desire bead-width and apply to substrate with cartridge gun. Firmly extrude the sealant into slot ensuring complete contact with joint faces. Tooling time is 15 minutes, tack free time is 20 – 30 minutes. The sealant should be tooled shortly after application before skin forms to ensure good contact with joint substrates. Uncured sealant can be cleaned up with mineral spirits. Use approved backing material for joints over 10mm deep.
