re seal or re impregnate honed travertine floor in bathroom?

[scorpy]

Hi guys,
Excellent forum you have here.

Was wondering if you could advise me on re treating a tricky travertine floor in my bathroom.

I have a floor consisting of two inch honed and filled travertine tiles. When laid down, I filled , impregnated and sealed the tiles.
However, due to a damp problem in the bathroom (now corrected), the tiles next to the external wall of the bathroom have become all mouldy with black mould that was due to moisture running down the inside of the external bathroom wall

I tried to remove the mould with a bal microshield tile cleaner and a tooth brush but that did not work. The only cleaning solution seemed to work was with bleach that got the mould out of the honed travertine tiles. However, this has probably effected the impregnator/ sealer that I used originally?

The only other way I can think of removing the black mould is to sand down the tiles to get the mould out but then the tiles will still have to be re impregnated /resealed?

Can any one advise the best solution to go from here?

Many thanks in advance for any replies or advice given..

Regards,

scorps.

Oww, I meant to ask..Does anyone know the brand of a chip restorer/ filler for a steel bath and if theres a like a spray I can use to coat the inside of the bath to get a glossey finish again? Or is this just wishful thinking?:lol:


Many thanks in advance for any ideas here
