good talking on the phone

Hi Anne,

From what you told us on the phone, we think laying stone during cold days is a very bad idea. The cement freezes and looses its ability to bond properly. The joints that you showed us would also not bond properly. They will tend to deteriorate over time. Too much pressure washing can also hurt the stone.

We think, based on the pictures, that a bad sealer can cause the discoloration. The efflorescence that seems to be coming out of the stone can be alleviated through chemical removal. However, you need to get the right chemical to do that. Call Prosoco at 1-800-255-4255 to get the best advice for the right chemical.

Whatever treatments you decide to do, do it in a small area, so you don't damage the whole patio. In other words, test before you commit to the whole project.

Great luck and we hope it all works out for you!!
