Smartseal Grout Magic – Black, 237ml – Professional Reviver & Colour Restorer – Long-Lasting Sealer Superior to Grout Pens & Paint – 15-Year Durability

This grout dye has worked perfectly - my bathroom floor looks like new. I have black tiles which had mismatched grey and white grout - it looked very shabby. I was concerned the colour may be uneven as I had two different shades of grout originally - however this was not a problem. I applied two coats (leaving an hour in between) with a small artists brush. The residue on the tiles I wiped with a disinfectant wet wipe. after 48 hours I have washed with water and bathroom bleach. As I had black tiles and was a applying black grout, it was not so much of an issue if the dye left marks on my tiles. I think this product would be more difficult to use if you were applying the black dye on white tiles! It is very difficult not to overspill onto the tile and I am not sure how easy it would be to wipe off. Be very careful to use a precise brush in the case

Very good product and easy to apply with a fin brush- just wished it came in smaller bottle.just did a full shower cubicle and used about 50ml.

I used black. It has good adhesion, though I wouldn't scrub at it. Light cleaning is fine. Application is not as stated. It's no good trying to wipe the wet excess paint from the tiles: you'll wipe half of it from the grout also. The solution is a find brush and steady hand to paint on the grout and not the tiles. Really pleased with the end result.

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

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 ,

I used black to revive the grout around white tiles. It looks fab where the tiles are whole ones. I took a razorblade to the grout to tidy it up first. Unfortunately after starting I realised that the tiles were VERT badly cut and all the chips and jagged edges are now painfully obvious. Just be aware before you go for dark grout that if your tiles are not cleanly cut, it dark grout will show this up. The product does a good job though. I couldn't find any other way than using a shed load of paper towels to wipe up each tile afterwards though. Maybe a huge stash of rags would be a better option.

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

This was really easy to apply with the use of a toothbrush. I originally used a light grey grout but regretted it and this was an easy solution without needing to regrout. Can't speak for longevitity yet but after a couple months it still looks good. It dried pretty quickly unlike other products I looked at that took days. My pot covered the grout of 20m2 of large floor tiles with some to spare.
