Wiseal 888 MS — Modified Polymer Sealant for Interior Applications
High-strength MS Polymer hybrid sealant — powerful adhesion, fast cure, paintable for premium interiors
Product description
Wiseal 888 MS is a one-part paste sealant built on Modified Silane Polymer technology — cures at room temperature, with high adhesion strength, fast cure, strong weather resistance and excellent compatibility across most construction substrates. After cure it forms a durable, elastic, paintable bond that needs no primer.
Optimised for interior fit-out — sealing tile joints, finish lines in bathrooms, kitchens and balconies, natural and engineered stone, composite panels, wood and metal. High extrudability even at low temperatures, neat bead profile, and stable performance from -50 °C to 80 °C.
Applications
- Sealing tile joints between construction panels — bathrooms, kitchens, balconies
- Sealing joints around sinks, bathtubs, natural and engineered stone
- Sealing aluminium-glass doors, wood-aluminium doors and composite panels
- Sealing paintable interior cracks — replacing non-paintable silicone sealants
