Air Barriers - Sika® MultiSeal-500
Sika® MultiSeal-500 is a prefabricated self-adhering sheet-type waterproofing membrane.
Sika® MultiSeal-500 is a prefabricated self-adhering sheet-type waterproofing membrane. It is composed of a tough multi-layer cross-laminated film that is coated with a rubberized asphalt adhesive. A release liner protects the adhesive and is removed as the membrane is installed. Sika® MultiSeal-500 is intended as a multi-purpose waterproofing membrane for use in sub-grade applications and under siding, exterior plaster, as a through wall flashing or anywhere it will be protected from long-term ultraviolet exposure. Sika® MultiSeal-500 adheres aggressively to most clean, dry substrates including metal, wood vinyl, masonry and rigid insulation boards. Sika® MultiSeal-500 may be used to waterproof foundations and other below grade structures, plaza decks, balconies, under siding, and exterior plaster. This advanced system bonds to the substrate and selfseals around nails, staples and other fasteners to prevent damage caused by water penetration.
Sika® MultiSeal-500 offers the contractor and property owner these extra features:
- Uniform thickness for dependable protection
- Self-seals around fasteners including nails, staples and screws
- High strength, high elongation, flexible - accommodates expansion and contraction of the substrates
- Protects ICF foundations and insulation boards from damage during backfill
- Outer film surface is compatible with most construction sealants
- Eliminates leaks - multiple layers of protection seal out water
- Rubberized asphalt won’t crack or dry
- Aggressively adheres - sticks in cool weather to common building materials for ease of application and to eliminate movement of water under the membrane
Usage
- Foundation wall, floor and planter waterproofing, under stucco and at head, sill chimney shoulder, pot shelves, parapets and pony walls
- Use for sealing SIPS building panels and around doors, windows and other potential leak areas
- Waterproofs and protects ICF foundations from damage
- Thru-wall flashing in cavity wall construction
