HYPERSEAL®-EXPERT Building is a low modulus expansion joint sealant, especially formulated to ensure bubble free cure even at very high temperature and humidity climatic conditions.
It cures by reaction with atmospheric humidity to produce a joint sealant with a 50% joint movement accommodation factor and excellent adhesion on substrates traditionally problematic for PU sealants, e.g. glass, aluminum, steel, polycarbonate, etc.
In this case, the substrate must be primed with MICROPRIMER-PU, which will re-enforce the concrete and produce a strong durable substrate for sealant application.
• Highly porous substrates, dusty surfaces or poorly compacted concrete, must have their porous bond area surfaces thoroughly sealed to avoid the possibility of air bubbles being blown into the uncured sealant if the substrate temperature rises.
• Not recommended for direct UV exposure. Sealant must be over painted after full cure with a good quality acrylic or polyurethane paint
Sealing joints in:
• in-situ concrete,
• precast concrete panels,
• brick and block work,
• water tanks and swimming pools,
• metal frames,
• aluminum windows and panels,
• irrigation channels,
• glass,
• granite & marble.
