Follow these guidelines for a smooth, low mess project.
Pay particular attention to CAUTION text in bold.
Assess the tile grout for damage/defects. Repair any holes or cracks and allow to fully cure before using Grout Rescue. NOTE: The grout surface must be sound to achieve a watertight and long-life sealed finish.
For best results, treat the grout lines with Grout Rescue Pre-Treatment Cleaner. This micro-etches, decontaminates and cleans the grout, allowing for optimum bonding. AVOID getting the cleaner onto SENSITIVE SURFACES such as metal and fabric - clean off immediately with clean water.
IMPORTANT: Complete a test patch to determine coverage and ‘time to remove excess from tiles’ for your specific grout and tile finish. Matt tiles must have excess removed sooner than smooth, glazed tiles for example. DO NOT proceed to the full project until you have established your timescales.
Apply Grout Rescue using your preferred method; 100ml brush head, Applicator Kit or 237ml bottle with a small brush (toothbrush or small paintbrush). Apply slowly and evenly to the grout lines, working in small sections.
Removing excess sealer from tile edges; either do it as you apply with a damp cloth and thumb edge, or you can complete a section in full as per your test times, then remove all the excess with an emulsifying pad or similar. ONLY use a fine mist of water to help dislodge residues if needed.
Continue the process until the tile grout colour transformation is complete. DO NOT apply too thickly as it may cause blistering/cracking and the sealer may not bond correctly.
Touch dry within 2-3 hours. Allow 48hrs before wetting the grout (in showers, wet rooms etc) or using cleaning products on the colourised tile grout.
Prepare the grout surface
For optimal results, we recommend all grout to be colour sealed must be primed first with Grout Rescue Pre-Treatment – this easy to apply spray will remove dirt and grime and prep the surface so that Grout Rescue adheres perfectly.
At Grout Rescue, colour isn’t just about aesthetics — it’s about precision, consistency, and confidence. That’s why all our products are formulated using the RAL International Colour System, the benchmark for recognised and reliable colour standards across the globe.
By using RAL colour codes, we ensure that the shade you choose — whether it’s Cappuccino for your bathroom tiles or Sandstone for your patio — is consistent every time. This eliminates any guesswork and guarantees professional, high-quality results, whether you’re a DIY homeowner or a trades professional.
The RAL system is trusted worldwide in design, architecture, and manufacturing. For Grout Rescue, it means you can mix and match colours with confidence, knowing your finished grout will be the exact tone you selected. No surprises, no mismatched shades, just a flawless, uniform finish.
This is particularly important when refreshing or transforming tiled spaces. Even subtle differences in grout colour can completely change the look and feel of a room or patio. By adhering to RAL standards, Grout Rescue makes it simple to achieve a polished, harmonious finish that elevates your space — quickly, easily, and affordably.
With Grout Rescue, colour is more than cosmetic — it’s trusted, precise, and designed to last.
Grout Rescue doesn’t believe in a one-size-fits-all approach. That’s why we’ve developed two specialist formulas, each designed to deliver outstanding results in the environment it’s intended for.
For internal spaces like kitchens, bathrooms, and tiled walls, Grout Rescue Colour & Seal provides a durable, long-lasting finish that protects against stains, mould, and everyday wear — all while enhancing the colour of your grout for a fresh, “better than new” look.
Outdoors, conditions are tougher. Weather, frost, and foot traffic can all take a toll on patio and paving grout. Grout Rescue X Colour Sealer is engineered specifically for these challenges, forming a water-, frost-, and stain-resistant barrier that protects your outdoor surfaces for years. It also keeps weeds and grass from growing between your patio tiles, preserving the clean, uniform look of your paving.
Both formulas are simple to use, designed for homeowners and professionals alike. With the right preparation using our Pre-Treatment cleaners, applying Grout Rescue is straightforward, fast, and highly effective — no re-tiling, no mess, just incredible results.
With Grout Rescue, whether your project is inside or outside, you can trust that there’s a specialist formula to deliver a long-lasting, flawless finish every time.
Grout Rescue isn’t just about colour — it’s about keeping your grout looking fresh and clean for years to come. When applied correctly, our colour sealers create a hydrophobic layer that causes most liquids to bead up and roll off the grout surface instead of sinking in.
Spills from coffee, wine, or sauces? No problem. Everyday grime from mud, dirt, or kitchen splashes? Easily wiped away. Even external surfaces like patios benefit, as seasonal dirt, moss, and lichen struggle to cling to the treated grout.
This protective effect makes cleaning faster, easier, and far less frequent, so your tiles maintain that newly-installed appearance with minimal effort. It’s particularly useful in high-traffic areas, busy family kitchens, bathrooms, or outdoor patios, where dirt and staining would normally build up over time.
By forming a barrier that repels liquids and resists staining, Grout Rescue helps homeowners save time and hassle while keeping tiled surfaces looking uniform, attractive, and welcoming.
With Grout Rescue, your grout isn’t just recoloured and refreshed — it’s shielded against life’s little accidents, making your home or outdoor space look its best, day after day.
Grout Rescue gives you the chance to achieve a professional-looking finish without the professional price tag. Our specialist colour and seal products are designed so that homeowners can complete stunning transformations with minimal effort, time, and cost.
Whether it’s refreshing tired bathroom grout, brightening up a kitchen, or giving your patio a new lease of life, Grout Rescue and Grout Rescue X let you tackle the job yourself — no tradesperson needed in most cases. That means you can enjoy the satisfaction of a DIY makeover that looks polished, uniform, and long-lasting, all at a fraction of the cost of a professional renovation.
With carefully formulated pigments and sealers, the results aren’t just cosmetic — they’re built to last, helping to protect your grout and pointing for years while maintaining a clean, attractive finish. The range of colours, paired with easy-to-use applicators, makes it simple to match, refresh, or even transform the look of any tiled space, inside or out.
Grout Rescue proves that achieving stunning, professional results doesn’t have to break the bank. It’s the perfect combination of quality, simplicity, and affordability — giving every homeowner the confidence to refresh and transform their home, quickly and cost-effectively.

Find out why Grout Rescue is so highly rated
After changing the colour of my kitchen worktops (with vinyl), my kitchen tiles didn't really match and I was considering painting them until I find this product! Very impressed with the outcome and how it works and I get to keep my original tiles.
Brilliant product, saved me from having to replace grout from between small mosaic tiles. Potentially saved me from having to replace the whole floor.
Just wanted to drop you guys a note and say what wonderful products you have, my floor looks amazing! almost new
We were honestly on the verge of covering over our tiled flooring before we bought this product as a final attempt at tackling the discoloured grout. This product has covered it perfectly after 2 coats and it looks so clean and fresh.
