Multi KSW Connect –

Professional Adhesive for Bonding Mineral Wool Boards in Insulation Systems

Multi KSW Connect is a high-quality, factory-prepared dry adhesive mortar designed for bonding mineral wool boards in ETICS (External Thermal Insulation Composite Systems). Its carefully formulated composition based on cement, mineral aggregates, and polymer modifiers ensures excellent adhesion to both mineral substrates and the fibrous structure of mineral wool. Multi KSW Connect enables quick, durable, and safe installation of façade insulation, regardless of building type.

Applications:

• Bonding mineral wool boards (both lamella and façade types) to mineral substrates such as concrete, cement plaster, cement-lime plaster, brick, or block masonry

• For use in external wall insulation systems (ETICS)

Key Features and Benefits:

• Very high adhesion to mineral substrates and mineral wool structure – ensures strong and long-lasting insulation bonding

• Vapor-permeable – allows walls to "breathe" and supports proper moisture management in the building envelope

• Weather-resistant – ideal for outdoor use, including areas with variable climates

• Plastic and easy-to-work consistency – simplifies application and even distribution of the mortar

• System compatibility – part of comprehensive façade solutions by leading insulation system manufacturers

Technical Data:

• Color: grey

• Consumption: approx. 5–6 kg/m² (depending on board type and application technique)

• Pot life after mixing with water: approx. 2 hours

• Application temperature: from +5°C to +30°C

• Packaging: 25 kg paper bag

Instructions for Use:

Mix the contents of the bag mechanically with clean water (approx. 5.5–6 liters per 25 kg) until a lump-free, homogeneous mass is achieved. The adhesive can be applied using the ribbon-dot or full-surface method, depending on the board type and insulation design. The substrate should be load-bearing, clean, dry, and free of grease, dust, paint residues, or loose particles before application.
