Product Details
Sikalastic®-390 Membrane is a two-part polyurethane waterproofing membrane designed to protect concrete surfaces from water penetration and cracking. Once applied, it cures into a flexible, rubber-like waterproof layer that bridges cracks and moves with the substrate.
This product is commonly used in parking garages, balconies, rooftops, walkways, ramps, and wet rooms where long-term waterproofing is critical. It cures quickly, allowing faster project turnaround and reduced downtime.
Sikalastic®-390 is solvent-free, low-odour, and easy to apply, making it safer for installers and suitable for enclosed or occupied areas. It is part of Sika’s proven Parking Deck and Traffic Coating Systems and complies with Canadian parking structure standards.
