Smartseal Grout Magic – Mid Grey & Pre-Treatment – Professional Reviver & Colour Restorer – Long-Lasting Sealer Superior to Grout Pens & Paint – 15-Year Durability

Very happy with the product on using it. Goes on easily, and goes a long way. I bought the sample version until I found the right shade as my floor tiles are tricky to match. The job itself needs a brush a touch smaller than your grout line, eg artist type brush, small damp cotton wool balls to wipe away excess paint on tile edges as you go, and calm careful work. Two coats worked; looks great again. Mines was a reasonably small job. For big jobs I would split up the work into stages. The product is good but the care and attention is absolutely needed to get it looking well done. Will now see how it lasts.

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!!

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.

Video made this product look easy to use. IT IS NOT! comes off the grout easier than it comes off the tiles! It says leave 15-30 minutes and then wipe off the excess….. I tried this, it wasn’t coming off my tiles so I had to scrub it off…. But that made it come off the grout but still be all over my tiles. Then as it was coming off it made the product all ‘bitty’ like rubber glue…. And it moves around and dries leaving ‘bits’ all over my tiles and and my bath. Nightmare product and it’s expensive for such a small tube. Would not recommend

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

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.

Totally revived my bathroom floor tile grout. Cleaned old grout with Smart Seal surface preparation. Next day applied Grout Magic to small areas, only had to wait about 10 minutes before wiping off residue. If the Grout Magic had dried too much on the tile edges I used a razor blade scraper to remove residue, easy as the tiles are smooth glazed. Then wiped over with a damp sponge cloth. Very pleased, worth the money, thank you.

I had to put 3-4 coats on to achieve an even grout line. After 2 coats my wife said it looks like there's mould on the grout. When finished it looks good from a distance, but close up it looks as though I've painted the grout lines with gloss paint. The best thing to use to paint this on, is a child's thin paintbrush.
