Do I need grout sealer

[Filip]

I have just finished laying - DIY a kitchen floor with 300x600 porcelain tiles with Tilemaster charcoal 3000 grout I have some grout sealer left over from my bathroom so do the experts recommend I use it on the new kitchen floor.
When I used it on my bathroom you could tell where it was used especially on some black grout because the grout that had it applied would not go darker when I added water so I do believe that it dose do what it says on the tin but do I need it with TM 3000

Not really. Won't harm though. Just make sure sealer is compatible with the tiles

Apparently lasts for 10 years ? How do they know ?

Most sealers won’t make ten years as people usually use bleach which strips it I think that it always depends on the use of neutral cleaners

Well I had a go with it but it would not touch the TM 3000 grout and it just sat there and beaded up so looks like the 3000 is the business.
