ARDEX EG 9 is an epoxy grouting material formulated with special resin system. It is composed of premium epoxy resin, water-based hardener, glass microspheres, white fused alumina, and functional additives. Compared with conventional epoxy color grouts, ARDEX EG 9 offers further improvements in yellowing resistance, service life, hiding power, and abrasion resistance, while also supporting customized color matching. The product combines practical application properties such as easy joint filling, smooth spreading, and easy cleaning, making it suitable for a wide range of uses. It is particularly ideal for grouting high-end wall and floor tiles, both indoors and outdoors, with joint widths of 1–10 mm. It is also well suited to wet areas or locations subject to longterm water exposure, such as kitchens, bathrooms, and swimming pools. In addition, the product is environmentally friendly and safe to use, with very low VOC content.
