Q: Will it make a tiled wetroom floor waterproof? We suspect water is leaking through fine cracks

No it will not! Penetrating sealer reduces water ingress and makes tile & grout more water resistant NOT WATERPROOF! If you want to do that then use PSRP Grout Colourant as that is a urethane colorant and that will make the grout waterproof. However, I would also be looking to see why it cracked in the first place

Q: hi can this be used on unpolished porcelaine

Yes no problemThe Original Penetrating SealerWATER, STAIN & SLIP PROTECTION FOR:* Sanded Grout* Quarry Tile* Ceramic Tile* Glazed Tile * Porcelain Tile* Polished Granite* Polished Marble * Stucco* Slate* Terrazzo * Quartz* Travertine* Agglomerate 511 Impregnator is the original penetrating sealer designed for the protection of all medium to dense porous surfaces. 511 Impregnator forms an invisible barrier that is resistant to moisture and stains while allowing vapor to escape. 511 Impregnator is not a surface coating and will not alter the natural look.

SPECIAL FEATURES:* Interior & Exterior Use* Less Expensive* OK for Food Areas* Superior Coverage

Q: Going to use this on white subways tiles. Will it stain them?

I cannot imagine it would impregnate a good quality glazed tile and I did not notice that the sealant had a yellow tinge (like some varnishes do) but you could always do a test patch which is what the manufacturer would recommend. The other option is to find a UK-based manufacturer of specialist cleaners and sealers (eg Stonehealth) who supply sample pots.

Amazing grout sealer

The media could not be loaded. 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 on the label!

Great product, does the job very well, easy and fast to apply. Water now beads nicely on my unglazed shower tiles/grout instead of being sucked up. Have already recommended to friends and family.
