Smartseal Grout Magic – Black, 237ml – 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.

Does not work at all waste of money! Do not buy it’s like watered down paint that does nothing

Ok, so when I grouted the tiles on the chimney breast in our kitchen, I totally should have used grey grout. Years later, with steam and fat splashes and grease, they began to look decidedly yellow. So I thought I’d get some grout paint and try to cover up the ugly. I plumped for this one. So - product-wise, it does the job and does it very well. It’s a bit thick going on (a little like that undiluted child’s poster paint in litre bottles). It is also VERY unforgiving if you don’t have a 100% steady hand and a very small brush. I sprayed on the cleaning solution (they are very prescriptive about PPE and it is quite pungent) but that didn’t touch the years of grease that had soaked into the grout. In the end I had to painstakingly use washing up liquid and hot water, with a tooth brush. Took me ages but it worked. I tried using a tooth brush to paint, to start with, hoping to wipe off the excess, but this wastes a lot of paint and it ain’t cheap. Also it flicks the paint everywhere. So I eventually bought some artist sable brushes and used those, which seemed to do the job ok, but again took me back to my days of painting lead figures for Dungeons and Dragons. I had to water the paint down (yes with water which works just fine) and this made the job a bit easier but it was my prep that let me down. Here’s my tips. If your grout is the least bit greasy, this paint will run off like a child at a funfair. If when you grouted, you were (like me) a bit liberal with where the grout went, then tidy it up first. This paint sticks to grout like a mother to a child who just ran off at a funfair. If your lines aren’t straight in the grout then this will show up every mistake. Don’t go ‘liberal and wipe off’ - take your time, the effort will pay off. Make sure your grout is grease free (and dry - it needs to soak in). Use a good detergent - the cleaning fluid is useless. Make sure your grout lines are clean and true. Use a small, good quality brush and take your time. You will either end up with something looking really nice, or something looking really nice from a distance. The paint will not be to blame if it’s the latter.

Magic , maybe re-name it , like hit and miss . I've got a small bathroom, I had to go over it 3/4 times some area's it was OK and alot wiped off , it was hard work . I tried 15 minutes, then 20 minutes, then 30 minutes it's hit and miss . The ytube videos look so simple and easy to do , trust me it's not , maybe the ytubers have shares in this . Or maybe it's just me ,

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.

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
