HG Tile Impregnating Protector Treatment 13, Pre-Treatment Protects Against Grease & Dirt Penetration, Silicone Free for Unglazed Tiles – 1 Litre (391100106)

l'avevo preso anni fa per trattare il cotto ed era ottimo, ora fanno questo qua ad acqua che e' come non dare nulla. come sempre quello a solvente che facevano anni fa non lo fanno piu

I've used this for over 30 years. It's used to seal my slate floors. It's as thin as water and virtually no smell. Very quick drying too.

Lo usé para un suelo de terraza que era muy poroso. Y en la zona donde tengo la barbacoa se manchaba mucho. De momento parece que funciona. Lo que más me interesaba era que dejase de ser tan poroso sin cambiar el color. Y así ha sido

It's easy to use, thin as water. I didn't use a roller as instructed but a paint brush and mostly poured from bottle on my marble table then spread it all over untill it soaks as much and then wiped it. I think it looks fairly glossier. My marble coasters didn't obserb any spilled water after the two coats.I used it on my matte teracotta tiles in the open shower, but water still stand on the tiles, doesn't slide off so not sure if it does anything, if it protects the grout.Time will tell.

I’ve been using the 14 grade for some time and wish I’d always laid down the 13 first, as working on a stone grouted floor does mean that without this preparatory step the grout sucks a lot away and needs proper sealing. Both items are excellent in providing a good sheen on an old quarry floor.
