Limestone Nightmare

[DHTiling]

Ok.. how many coats...?

Just to add.. Not the best sealer for porous limestones..

 

[Groutcho Marks]

Two in total. One before grouting one after. I have tried some lithofin colour intensifier on a couple of tiles it darkened a bit. Could a few coats of this be an answer?

Be careful...mixing sealers could be costly... personally i would have used lithofin stainstop or LTP mattstone..

Also how long are you leaving the tiles before you are trying sealers..?

restoration work is not my forte, but I'd imagine that a stripping solution for the sealer, altho' you did say it was HG impregnator, and then maybe an alkali solution to neutralise the acid, would that bring it back maybe?

I left the floor for two weeks after tiling before i sealed then a week and a half after grouting.

I mean after stripping it...

And did you neutrilise the stripping solution.

Thanks doug. As I used the acid i was thoroughly washing the acid off as I worked across the floor so I don't think there is any still present.

A couple of days. I was washing as I went with clean water.

So how does the floor stand now...?.. clean or re-sealed.

Re-sealed now. Do you think the acid would have removed the first coat of sealer?
