Why Getting Your Grout Color Right Actually Matters
Repairing a small section of grout should be simple — until the new grout dries and suddenly you can see exactly where the old ends and the new begins. A grout repair that doesn't match isn't a repair at all; it's a new problem sitting right next to the old one.
The good news: with the right approach, matching your existing grout color is straightforward. This guide walks through exactly how to identify your color correctly and get a seamless result the first time.
Understanding the RAL Color System
Our grout is manufactured to match specific RAL codes — a European color-matching standard that assigns every shade a unique number. The advantage is precision: a RAL code means the same exact color every time, batch after batch.
That's exactly why the identification process below works so reliably — once you know what to look for, matching your color becomes quick and simple.
How to Find and Use Your RAL Code
RAL codes are a universal standard — a given color name (like "Beige" or "Anthracite Grey") corresponds to the same RAL code no matter who manufactures it. This makes finding and matching your color simple:
- Search online. A quick search for your grout's color name plus "RAL code" will typically show you the matching code in seconds — RAL codes and their corresponding names are widely published and easy to look up.
- Buy with confidence. Since our grout colors are manufactured to these same standard RAL codes, a product listed under the color name you're matching is manufactured to the same code — so you can order it and use it with confidence.
- Still not sure? A physical RAL color fan deck (available at most hardware or paint stores, or online) lets you hold real color chips directly against your grout in daylight to confirm the exact shade before you order.
How to Identify Your Existing Grout Color — Step by Step
- Clean the area first. Dirt, soap residue, and years of mopping can shift grout's apparent color — often making it look darker or more yellow than it actually is. Clean the section you're matching with plain water and a soft brush, and let it fully dry before judging color.
- Check it in natural daylight. Indoor lighting — especially warm LED or incandescent bulbs — can shift how a color reads. Compare samples near a window during the day for the truest read.
- Compare dry, not wet. Grout darkens when wet and lightens again as it dries. Always match colors on fully dry grout for the most accurate result.
- Account for natural fading. Grout exposed to sunlight, cleaning chemicals, or years of foot traffic often fades a shade or two lighter than its original color over time. If your grout is older, the closest match is often a shade darker than what you're currently seeing — our full color range covers these in-between shades too.
Tips for the Best Match
- Match in daylight for the truest color read.
- Match on dry grout, not wet.
- Match to the current (faded) shade you see today, not the original installation color — that's what will blend seamlessly.
- Factor in sealed or glossy grout, since a sealer can shift the apparent finish slightly.
Follow these four steps and you'll land on the right shade with confidence.
Frequently Asked Questions
Will grout from a different production batch match perfectly? Yes. Our RAL-based formula is manufactured to a precise, consistent standard, so every batch is made to match the same exact shade — order with confidence.
Is a slight tone difference between old and new grout normal at first? Newly applied grout can look very slightly fresher right after application simply because it hasn't been exposed to light and cleaning yet. This evens out quickly as it settles in, and the color blends beautifully with your existing grout.
What if I'm not sure which shade to choose? Use the daylight check above and compare against our full color range — with RAL-matched precision across every shade, you'll find your match quickly.
