DUNLOP GX-500 Flexible Grout is a water and frost-resistant powder-based grout suitable for use with both wall and floor tiles. Ideal for grouting ceramic, porcelain, and mosaic tiles in interior and exterior locations including power showers (without body jets) and swimming pools. The flexible nature of the product reduces the risk of cracking, leaving a super smooth but hard wearing finish without patchiness or surface discolouration. Also suitable for use with brick slips, refer to Technical Department for advice. For the perfect finish use with DUNLOP FX-90 Silicone Sealant, available in matching colours.
