This system uses a high-performance, solvent-free, two-component epoxy putty designed for surface filling, fairing, and sealing fine cracks or pinholes in concrete, masonry, or metal surfaces. The putty provides excellent adhesion, high mechanical strength, and easy application even on vertical or overhead areas without sagging. It is typically used to fill surface imperfections, seal joints, or smooth rough areas before the application of protective coatings, ensuring a durable, defect-free, and smooth finish.
