Perodic cleaning will not add enough water to cause a problem. As John said I would make sure that all the moisture is out of the stone before I would apply any sealer or impregnator.  Although impregnators breathe, they will slow down the evaporation rate.

Baird,

 

If the sealer has an acrylic in it is not truly an Impregnating Sealer it more of a topical sealer. a true Impregnating Sealer leave nothing on the surface.

John,

The sealer I used was Aldon SBS which is an impregnating sealer but has an acrylic content and will build up a slight sheen if more than one coat is used.  That is What we removed.  The rest of the floor has a slight sheen to it although I have no idea what sort of sealer was originally used.

First the efflorescent is going to continue to come back until all the moisture  is out of the stone. if moisture is still getting into the stone you will never stop this problem. 

 

You mentioned yo9u had to strip off the sealer. does this mean you used a topical sealer? if you used an impregnating sealer you would not need to strip of the sealer before removing the efflorescence.

 

You can use a mild acid to remove the efflorescence and then re-seal using an Impregnating Sealer.

 

If you use this process you can walk on it as soon as the Impregnating Seal has cured ,

Hi.

We have a job that required removing masonry from a rough granite floor where a planter had been mortared in place.  We used some good products to remove the residual mortar and then sealed (I talked about this in an earlier post).  The sealer we used was Aldon SBS Sealer.  It was good for a while but then quite a lot of efflourescence came back (I believe it came from the hard water being absorbed by the granite floor over many years.  We also have been getting a lot of rain recently). We then stripped the sealer and applied Aldon Efflourescence treatment.  Each time we have applied it (about three times) the efflourescence came back, but less and less.  I put more on last Thursday and checked today and it was in pretty good shape but not perfect. I am a little concerned about reapplying the sealer and, if it doesn't eradicate the efflourescence, I will have to strip again.  Constant treating with efflouresence treatment makes the floor slippery.  Are there any other products that anyone knows about that might either a. be a good maintenance type efflourescence treatment that could be walked on immediately after application, or b. another sealer that really does the job to remove/hide efflourescence and also color enhances?

Thanks so much.

Baird
