Wall & Floor Grout Protector, Kitchen & Bathroom Tile Grout Sealer, Colourless Between Tile Sealant & Waterproof Grout Treatment, Anti Stain Protection for Grouting, Repels Oil & Liquid - 250ml

I applied this to my tiles in my new bathroom about two years ago. This stuff is an absolute pain to apply, especially to a fully tiled bathroom of metro-brick style tiles. You need to use an artist's brush and be diligient about washing off the excess. The upside of this is that it much less messy than the spray type. You're also concentrating the material in the grout lines rather than all over your tiles, so you're not wasting any.Once you get two coats down in a shower area it's basically bulletproof. Water beads straight off the grout and you can clean off soap scum easily with a sponge. Even now I never see the grout change colour when it gets wet. Go into it with eyes open to the time it'll take, but a few hours applying this is far better than having to redo the grout after 18 months because it got soaked.

Quite easy to apply, with the 2 pipettes supplied.No indication of how long it lasts - like, typically 2 to 5 years.Preparation of clean, dry grout is essential

I used this on my tiled shower area, and it was very quick and easy to paint the grout. The longest time was cleaning the grout first, and now it's painted, you can see the grout is no longer porous.

seems to be working OK but could do with a better method of application as it takes rather long and messy

WOW! Skeptical at first as when looking for this product "HG Wall & Floor grout protector" to STOP leaks from the shower when taking a shower, the wall tiles looked ok but on closer inspection you could see very fine breaks in the grout and gaps between tiles and grout. The floor under the bath was very wet after a shower. Having checked for leakage and small amounts of condensation I decided to use this product.I was told by local stores including B&Q this would not work (They had none in stock anyway) and tried to sell something else which was not even for the job.Any way I tried it yesterday followed the instructions apart from they say use 2 coats but I used 4, you cannot see when it is on no mess no staining of tiles or grout and very easy with a brush and yes again WOW! it works. Thanks again HG as I do use your products for most of my ventures.

It's not a bad product but, make sure your grout is perfectly clean before applying product.

I don’t often write reviews, but I felt obliged to given how good this was. I had a dodgy batch of grout that started breaking down after a couple of months. I was pretty gutted. I applied this (after trying others) as a bit of a last resort, and it’s been excellent. Water just rolls straight off of it. Still fine after a year. No mould. Would recommend

Used it to water proof grout in the shower (who knew that was a thing). Put on three coats after re grouting, it’s invisible and works well. After use cleaning is much easier and no more staining on grout. Well worth the money. We used a paint brush to apply. Quality product.
