Palace Anti Mould Grout

Palace Anti Mould Grout is a high-performance, flexible cement-based grout designed to deliver long-lasting results in both residential and commercial tile installations. Available in a wide range of colour shades, it’s suitable for joint widths of up to 15mm, providing a clean, consistent finish around ceramic, porcelain, and natural stone tiles. What sets this grout apart is its built-in fungicide, which actively prevents the growth of unsightly black spot mould—a common issue in damp or humid environments like bathrooms, showers, and kitchens. This makes it especially ideal for areas that require both hygiene and durability. Designed for flexibility and strength, Palace Anti Mould Grout is also well-suited to modern installations, such as tiles laid over heated sub-floors or plywood overlays. It can be applied easily with a rubber squeegee or sponge, and it offers a generous 4-hour working time, allowing for detailed and precise grouting, even on larger projects. Whether you're working indoors or outdoors, this grout offers high abrasion resistance, minimal shrinkage, and excellent long-term performance. It conforms to BS EN 13888 CG2 WA, ensuring it meets the high standards expected for modern tiling work.
