Today I have been slaughtered (and not in a drinky in the gutter kind of way). Even though we finished this contract a year ago, the client can still call me back in for defects, this is one of my 'defects' a black and white patterned patio, which they now tell me the white marble has turned brown. Tomorrow the 'expert' is turning up to view this floor, tonight I will write my report, but before I do that I just wanted a second opinion from someone. For your information, it was dry laid and checked in Portugal, and we laid it on white adhesive here. I believe I know what has happened but I just want someone to have a look at these photos.

Thanks in Advance

Re: - Advice

Hi Lynn, without stating the obvious it looks like someone has spilt something on there by the colour of the grout which has been affected, looks like creosote or something, assuming that the patio is outside.

Looks like staining from above.

Re: - Advice

Hi Pebbs, this could happen if you drop some multifinish on white marble. even if it's been sealed, plaster could still go in to the stone deep. Hard to say, i beleave your tiles are honed so easier to stain then high polished finish.

Re: - Advice

My 1st thought is somethng has been spilt/dropped on it,but,in pic 2 on the left the grout line looks clean.

Re: - Advice

No they don't have dogs, they hardly use this patio area. Then I remembered something from another job years ago, when we had installed a white marble kitchen top, and it had been stained orange due to a pumpkin sitting on it. There is a 'living wall' that has been installed, and I started reading, about dead leaves and twigs decomposing and tannin being released. I now believe the staining is from the living garden debris that has been left there over the winter. So that's what I'm going with.

I think I am right...well I hope so!

Re: - Advice

i think you are half right seen this before with small plant pots the water get traped under neath with no escape this causes the water to get pushed into the stone a capillare reaction takes place. for water and stains not to go into the surface it needs air flow to dry out the water traped under any surface ie draining boards pepballs garden candales if the water cant escape or is traped between two surface it will push into the weakest

Re: - Advice

just noticed on the pics if you look closely by the staines you will see new scratch marks on the tiles where some think have been pulled plant pots or table legs these are new and clean some one has removed the offending objects

Re: - Advice

I think its tanin from leaf fall

 

[MARBLE_TONY]

Re: - Advice

This is so common in white marble, one it is a natural product sitting outside! My thought would be Iron content in the stone with all this water the iron has probably been "activated" and caused the staining. Its a natural product at the end of the day and nothing you have done wrong

Re: - Advice

I think marble tony is near the mark.
i have seen this before but cant remember the cause.
plant pots do cause stains but they are easier to identify. tannin also stains stone outside but it would be more evenly covered over whole area i think.
i have seen strange discolouration coming through stone from base in past even if laid in white adhesive.
do you know what the base is made up of.
water does of course get in to marble /stone over a period of time even if sealed and this could cause a mineral migration in stone

Re: - Advice

just seen this thread,and yes i can confirm it is staining from plant-life rotting down over a period of time ,when we marblelight a swimming poo in white l iif its an outdoor pool and the winter cover is a bit late going on you have to make sure no leaves a left as they sink to the floor of the pool and break-down over the winter period and the end results are exactly the same, we also get hair slide's/clips rusting and the rust staining in white pools

Re: - Advice

Could it be from metal garden furniture rusting. Only asking as I have just laid stone on my patio and I have stains similar only on Indian stone

I agree here, also seen some tree with purple berries falling on limestone and staining badly.
