Product description
Sika Stixall Ultra Grey combines strong initial grab with permanently flexible sealing in one cartridge. Its grey finish helps coordinate joints with grey frames, panels and fittings.
Suitable for interior and exterior work, its STP hybrid formula adheres to common materials including timber, concrete, plasterboard, metals and many plastics, generally without priming. It can also be applied to damp surfaces.
Certified for façade and sanitary sealing, Stixall Ultra suits perimeter joints around doors and windows, fitting trims and jointing cladding panels. Once fully cured, it can be painted with compatible coatings following a small-area test.

Unsuitable for permanent immersion, swimming pools, structural glazing, PE, PP, PTFE, natural rubber or EPDM. Approved for food preparation areas, but not direct food contact.
