Product description
Sika Stixall Ultra Black combines strong initial grab with flexible sealing in one cartridge. Use it for fitting trims and panels, perimeter sealing around doors and windows, and other compatible bonding and maintenance applications.
Its STP hybrid formula adheres to common building materials including timber, concrete, plasterboard, metals and many plastics, generally without priming. It can be applied to damp surfaces and remains permanently flexible after curing.
Certified for façade and sanitary sealing, Stixall Ultra is suitable for interior and exterior use. It can also be painted with compatible coatings after full cure; test a small area first.

Unsuitable for permanent immersion, swimming pools, structural glazing, PE, PP, PTFE, natural rubber or EPDM. Although approved for food preparation areas, it is not suitable for direct food contact.
