Black Limestone Paving Nightmare!!!!! Please help!!!!

[Unregistered]

Hello,

I have just laid black indian limestone in my garden. I am halfway through grouting it all but tested the jet washer on the finished bits to see how it came out. Unfortunaley the slabs don't look any different. There are sandy patches (even though i got all the excess cement off the slabs) all over the tile, and even the dust from when cutting the tiles appears to have absorbed into the slabs. The guy i bought it off supplied me with a sealer to put on after i grouted and cleaned the tiles and said everything will go black. However, after spraying water over the finished slabs, the tiles go black but all the marks still show through.

Please help!!! I don't know how to fix this.

Thanks.

They should have been sealed before grouting..

You might need to use a residue remover..

Hi, i've now registered and attached a picture. Unfortunately, couldn't load the original because file too big but took a picture of the original on my phone. Not the best quality but gives you an idea. The darker bit is water on the slabs.

Thanks

OOO not nice...

The dark is emphasising it i think.. Can you take some more tomorrow unless you have some daylight ones,,then they need resizing to no bigger than 2400x1200

Area is 34m squared.

Jesus..

Ok that is one badly stained area...


With it being Black limestone i was worried about etching it when recommending a cleaner.. but that is well stained..

were you not advised to seal first..?
