Sikalastic - 612 5L Polyurethane sealing membrane

Sikalastic®-612 is a liquid, cold-applied, one-component, polyurethane-based film with curing technology that is activated by moisture but is not affected by it during curing. It matures to form a durable seamless sealing membrane for exposed room surfaces.

• Cool application, does not require heat or flame
• Seamless membrane
• It can be reinforced with reinforcement where required
• Easy to repaint - no need to remove the existing layer
• Cost-effective life cycle extension for failed room seals
• Water vapor permeable, allows the substrate to breathe
• Elastic, retains its flexibility even at low temperatures
• Good adhesion to most substrates, see primer table
• Rapid ripening, not affected by rain almost immediately after application

• Waterproofing in new constructions and renovation works
• On room surfaces with complex details, even in cases where accessibility is limited
• Cost-effective extension of the service life of failed rooms
• Waterproofing under glued tiles on balconies and terraces
