Amazing grout sealer
Honest review. Our bathroom fitter didn't seal our grout lines. Water was absorbing into the grout and leaking down back of bath. Bought some grout sealer from Topps tiles and applied 4 coats but water was still absorbing in. Searched for best grout sealers and came across this. Bit wary as it has a cancer and reproductive warning on the label and on Amazon description. I opened the windows and wore a face mask and latex gloves. Tipped some product out into an old double cream plastic pot and applied on the grout lines with a paintbrush. Left for 10 minutes and wiped off excess with kitchen towel. Reapplied another coat after 4 hours and left to dry for 36 hours. Used shower and the results were amazing. You can see the water beading up and running over and down the grout lines and tile faces. Absolutely amazing product. I would definitely recommend to anyone who wishes to seal their grout. Dearer than all the other ones but obviously you get what you pay for. The bottle will last a lifetime!!! No more leaks!!! Yay!!!

Does what it says.
As grout is inherently pourus I was looking for a sealant for a bit more protection. Water beads perfect on the grout as advertised. Happy but you pay a premium for it.

Hasta el momento el producto ha funcionado bien. Fácil aplicación, lo absorvió bien el granito y no lo deja manchado, sigue conservando el mismo aspecto que antes de la aplicación.

Very good product.Got this to seal my slate floor.Easy to apply very natural finish and stops the slate flaking.In the bath area applied on the granite floor it works as a sealant and gives a subtle roughness to the surface making it less slippery.

It is very easy to apply the product on the floor.
