Smartseal Grout Magic – Dark Brown, 20ml – Professional Reviver & Colour Restorer – Long-Lasting Sealer Superior to Grout Pens & Paint – 15-Year Durability

I used the light brown version of this grout restorer and have to say, the colour match was spot on. It blended really well with the existing grout and instantly made the tiled area look fresher and much cleaner. The product itself works well and gives a more even, professional-looking finish compared to standard grout pens. It also seems quite durable once applied, which is reassuring. That said, it’s definitely not a quick job — especially if you’re doing a whole room. Because it’s quite precise work, it takes a bit of time and patience to apply properly. Worth it for the end result, but something to be aware of before starting. Overall, really pleased with how it looks, just be prepared to set aside some time to get through it all.

The product absolutely works and you can get a good finish, but how it comes out is completely down to your preparation, method, and how good the grout has been done in the first place. Firstly, you need to clean the grout thoroughly, if there's any grease on the kitchen grout or slime on the bathroom grout then it will not penetrate and will come off when you rub off the excess. As someone else in the reviews has said, a wire brush (I used a firm toothbrush) is a good idea, a scourer at least. Secondly, the instructions say that you can remove the excess immediately but I haven't found that to be the case. It needs a good 45 minutes to an hour to soak into the grout, and at least two coats. Lastly, and this likely only relates to darker colours; if your grout is poorly done (as mine was) then making the colour darker show up the poor workmanship. Excess grout on the tiles will show way more and uneven tiles will become more apparent. If you're doing white on white then you should be fine. A decent product, but needs to come with MUCH better instructions and support - a guide video would do the trick.

Really impressed with this product. Our kitchen tile grout was very old and had gone almost totally black in places, it looked awful and felt like it was never clean, despite scrubbing and bleaching. This product has made the grout look new and the floor so much cleaner. It's been nearly a year since we used it and it still looks perfect. It isn't difficult to use, but it does take a LOT of work across a large area, so be ready for that... But it is worth it! We bought a stiff bristled paint brush that was the width of our grout lines to apply it, which worked really well. Wiped off the tiles as we went. You don't need a lot - it looks better if you use as little as possible and really work it into the grout with the stiff bristles. We used the brand's grout cleaner to prep before applying and I think it made a difference. Basically, it's a whole lot of work to do and my back hated the process but the result is excellent! Wish we had done it sooner.

Absolutely rubbish, doesn't colour anything, the dark grey is not not dark it is lucky if you could call it mid grey

So easy to use. Made the grout come up like new. Had a friend try and tell me it wouldn't work that well, and they were amazed how good it looked and how easy it was. Did the kitchen first 2 years ago and still looks brilliant. I did dark grey straight over white. No pretreatment. Just a quick clean, let it dry and then painted on, not perfect, wiped off and it looks like it has been newly re-grouted. Full kitchen took less than half a day!!

This is a very good paint but I ordered the ivory and unfortunately Its more of a pale yellow against my tiles.

Very surprised but pleased I bought this. It covered a larger area than I though it would. Easy to use and I was able to clean the tiles to remove excess

very unhappy i paid a lot for what came just one bottle i thought id paid for 3 like picture showed but was horrible to apply even with a fine art brush so dissapointed it was hard to clean off tile its impossible to get it only on grout
