This all depends on the type of salts and the porosity of the stone. If the pores are small than the stone has what is called microporosity. Salts can than become trapped in the pores which can lead to spalling. If the pores are large, this is called Macroporosity, than the salts may be easier to escape.  Regardless of the pore structure, efflorescence is only stoped by getting rid of the moisture. You never ever want to seal the stone..This will only abate the evaporation process and could lead to spalling.

I am thinking, regardless of the surface type or location, if efflorescence is present, that is the 1st indicator of moisture.  The second thing I am thinking is that efflorescence is actual mineral moving through the pores and then they cluster together.  Couldn't they eventually break away at the surface if they are left untreated?  I do know how to treat efflorescence.  I am just looking into this as a what if scenario

well there is a certain granite project in town , made of black absolute, that was made without benefit of weep holes that has certainly been severely damaged by it...everyone in town has looked at, and it is still there..very badly discolored, and eventually i would think it would start decompossing the stone. The other part of the story is getting paid for the work..it is a huge planter that was made without benefit of a liner or waterproofing membrane. For the most part, yes i think it is just cosmetic, but  i do think there is also potential damage as well.

Subject: RE: [sccpartners] Efflorescence Question

It's just the natural salts coming through and although it looks unsightly I've never heard of damage. Is it on the floors or walls and is it marble or another material. You can actually saturate it (it'll take a few trips) with water and agitate to draw the excess salts out or if it's a material that won't isn't acid sensitive use Limescale remover from Prosco or a mild acid.

Hi all,

I am familiar with efflorescence but have a question about what it can do.  Am I correct in thinking that if efflorescence goes untreated that it can cause damages?  Couldn't it build up and erode the surface? Or is it just an aesthetic thing?
