The Dunlop Flex Grout GX-500 is a premium, polymer-modified, powder-based tile grout engineered for demanding professional applications on both walls and floors. Carrying a CG2WA classification under BS EN 13888, it delivers exceptional durability, high abrasion resistance, and significantly reduced water absorption. Its versatile formulation accommodates joint widths ranging from 1mm up to 15mm, allowing tilers to use a single, reliable product across various tile formats, including ceramics, porcelain, mosaics, and natural stone.
 
Enhanced with advanced polymer additives, this grout offers high flexibility and robust resistance to freeze-thaw cycles. This makes it an ideal choice for challenging environments subject to minor structural movement, vibration, timber overlay substrates, and underfloor heating systems. It is fully certified for use in wet areas such as domestic bathrooms, power showers, wet rooms, and commercial swimming pools without compromising its structural integrity.
 
Engineered to minimize common installation issues like efflorescence, patchiness, and surface discoloration, the GX-500 ensures a uniform, hard-wearing, and aesthetically clean finish. Available in convenient trade packaging and a variety of complementary colorways to match modern silicone sealants, it provides both the functional resilience and the polished look required for high-end tiling projects.
