FERROCEM 520/Gray is a fine-textured, gray skim coat mortar with high-polymer content for superior adhesion. It's designed for thin applications (0.5-2 mm) to fill pinholes, smooth out the surface of precast concrete, or correct rough textures on general plaster walls before painting or wallpapering.

This product is suitable for both interior and exterior use. Once dry, it can be easily sanded for a perfectly smooth finish.
