Product Details
Sikalastic-391 N is a two-component polyurethane wear layer designed to protect Sikalastic-390 waterproofing membranes while adding a durable, slip-resistant surface.
It is mainly used in parking garages and traffic areas, where surfaces are exposed to vehicle movement, abrasion, and wear. When combined with broadcast quartz sand, it creates a tough, anti-skid finish that improves safety and extends the life of the waterproofing system below.
This product cures into a hard yet flexible coating, allowing it to handle traffic loads without cracking. It is solvent-free, low-odor, and supplied in pre-measured units, making it safer and easier to mix and apply on site.
