Thanks for your reply
If you could point me towards some products then I would be grateful
I assume that a decent sealer from Rompox cant be used to seal the existing sealed and non-sealed slabs then?
The LPT Grime remover is pretty good, after cleaning some slabs i hosed it down and inadvertently got some ltp stuff on the already sealed stone, when it dried off you could see that the sealer had been removed.
I don't want to throw money away here but want to get it right so any products you suggest I will certainly look into!
The LTP grime remover shouldn't have removed the sealer?? says a lot for the sealer really!!! This LTP Matt sealer? is it an impregnator or a surface sealer, as it sounds like a surface sealer. Anyway, you will need to remover all the LTP sealer so a strip, if it is coming off that easy then Mira Strip will do this,
Here is a link for the product. http://www.tilinglogistics.co.uk/Tile-Fl....miracle
What I would do then is an alkaline clean to clean the surface,
Now you are going to need to check that there is no resin or mortar stains etc as a sealer isn't going to cover these. If you are happy that the surface is as clean as possible, once it has thoroughly dried sealer with a decent sealer, I use this one on Black Limestone,
There are other sealers that are good, Dry-Treat, Lithofin and I have tested Resiblock's natural Stone sealer and results were good.
Just remember you need a colour enhancing impregnating sealer for Black Limestone.
