Limestone floor - colour issues around edges after grouting - TilersForums.com

You know sales

Do you have an off cut that you can grout the face of then let that dry and see if it stains also get another off cut and just get it wet with clean water and see how that looks .

I can give that a go, what are you thinking??

 

[Dumbo]

To see wether it's grout stain or dampness

Need to seal the face before you test

i only ever use lithothin products they very rarely go wrong.
what grout did you use?

The beauty of rapid all in one is you can seal damp stone and it lets the moisture out. Hopefully this sealer also let's the moisture out. It's ok using lithofin if you have loads of time on your hands .
That does look to me more like grout staining than moisture ingress.

Thanks for all the replies guys, I had only grouted 15m2 of 80m2 so stripped off the sealer and sealed remaining 65m2 with two coats of universeal rapid all in one, grouted and everything is awesome with that part of the floor, so now I’m left with 15m with this water ingress/staining ..... I’m really thinking it’s staining....

Tilemaster grout 3000, almond, really come up nice, lovely grout , joints were only 5/6 mm and tile 15mm thick so didn’t feel the need for wide joint

Gents, thank you for all your input , always appreciate it in times of blind panic!! All sorted, Harry has asked me to mention directly at Julian that it was indeed stained rather than moisture think he’s on the wind up!! Managed to get it out with the ltp grout cement and salt remover, the non acidic sister of grout stain remover. Brilliant stuff, think it’s pretty new on the market, check it out fellas
Upwards and onwards god speed!!

Lesson there for me then, never use hydro seal and always call Harry when I need advice

An after pic , great product

 

[hmtiling]

Water ingress into the unsealed sides of the stone and trapped under the sealed surface. Doesn't look like a dark grout so should stain and should dry out slowly over time.
Hope that's what Harry said

I won't tell a soul mate
