Enhance your space with the StoneCare4U Essential Charcoal Perfect Grout. Offering unbeatable coverage and long-term sealing power, it restores and renews wall and floor grout to a better-than-new condition by sealing and recolouring. It contains all the ingredients you need to return any grout to an almost brand-new condition with ease. How To Apply: Make sure the grout joint is clean and thoroughly dry before applying. Shake the bottle and mix well before use. Apply product thinly onto the grout joint using a brush or sponge, working it evenly onto the surface. Wipe away any sealer from the tile surface instantly or within 60 minutes of application. For best results, apply two coats, allowing one to two hours of drying time between applications. Allow a further 48 hours for drying time before wetting (using the shower room) or cleaning the treated floor area. Tip: If using more than one bottle of a single colour for an application, mix all materials to ensure colour match and consistency. Important Note: This product is not recommended for use around porous surfaces, i.e. unglazed tiles and natural stone surfaces, as it could permanently stain. Poor application, applying the product too heavy or thickly onto the grout joint can result in blistering, cracking and de-bonding of the grout colour sealer. Coverage: 3-15m² per 237ml bottle. This will vary depending on tile size and grout width. Quantity: 237ml.
