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?
